Implosion sound  

Science Journals Connector (OSTI)

An open end axisymmetrical cavity is used to study the generation of implosion sound. The cross section of the cavitys profile has a shape which will distort the wave front of a plane shock wave converging it into a single point. Hence a spherical collapsing phenomenon can be approximately achieved when a shock wave propagates into the opening of this finite size artificial cavity. Through the shock and shock interference mechanism a strong impulse therefore is generated at the focal point caused by the pressure difference between the inside and outside of the cavity. This highly localized impulse then is radiated out from the opening of the cavity as a sound projector. A prototype model of 0.5 l size has been constructed and tested in the laboratory. The preliminary experimental results indicated that this device can reach a peak sound pressure level of 146 dB//20 ?Pa in air and 185 dB//30 ?Pa in water with an ambient pressure of 1 atmosphere (1 bar). The 50% pulse width is about 20 and 30 ?s for air and water respectively. Analysis and application of this type of sound projector will be discussed.

Sound | Open Energy Information  

Open Energy Info (EERE)

Sound Sound Jump to: navigation, search Improved engineering and appropriate use of setbacks near residents has largely eliminated the problem wind farms had with noise in the 1980s and 1990s. Aerodynamic noise has been reduced by advancing blade design and orienting blades upwind of the turbine tower. A small amount of noise is generated by the mechanical components of the turbine. Modern wind turbines are designed with noise reduction in mind. Sound power levels at the source of a wind turbine are in the range of 90-105 dB(A). Proper setback requirements reduce wind farm sound pressure to background-noise levels. For example, at a distance of 350 meters, the sound pressure level for a wind farm is typically less than 45 dB(A). Rural background sound pressure is typically around 30-45dB(A). Higher wind

Zero lattice sound  

SciTech Connect (OSTI)

We study the N{sub f}-flavor Gross-Neveu model in 2+1 dimensions with a baryon chemical potential {mu}, using both analytical and numerical methods. In particular, we study the self-consistent Boltzmann equation in the Fermi liquid framework using the quasiparticle interaction calculated to O(1/N{sub f}), and find solutions for zero sound propagation for almost all {mu}>{mu}{sub c}, the critical chemical potential for chiral symmetry restoration. Next we present results of a numerical lattice simulation, examining temporal correlation functions of mesons defined using a point-split interpolating operator, and finding evidence for phononlike behavior characterized by a linear dispersion relation in the long wavelength limit. We argue that our results provide the first evidence for a collective excitation in a lattice simulation.

Transmission of sound through suspended ceilings from HVAC terminal units  

Science Journals Connector (OSTI)

An ASHRAE project to investigate factors determining the sound pressure levels in rooms below ceilings concealing air?terminal units has been completed. Four terminal units installed close to the six ceiling types used were the major noise sources. They were supplemented by two simulators powered by loudspeakers. Sound power was measured for each device in the 156 cubic meter test room in its reverberant condition. The levels in the room were measured for each combination of source and ceiling tile. Sound pressure level was measured as a function of distance from two sources in the room below. The main intent of the project was to validate ARI Standard 885 which provides a calculation method for such situations. Differences among ceiling types were less than expected; leakage around the edges of each panel is a dominant transmission path. Ceiling attenuations at low frequencies were found to depend on the area of the lower face of the units. Sound levels in the room were essentially uniform when the source was above the ceiling. The decay of sound with distance from the sources below the ceiling was found to depend on the inverse of the room reverberation time.

Puget Sound Dissolved Oxygen Modeling Study: Development of an Intermediate-Scale Hydrodynamic Model  

SciTech Connect (OSTI)

The Washington State Department of Ecology contracted with Pacific Northwest National Laboratory to develop an intermediate-scale hydrodynamic and water quality model to study dissolved oxygen and nutrient dynamics in Puget Sound and to help define potential Puget Sound-wide nutrient management strategies and decisions. Specifically, the project is expected to help determine 1) if current and potential future nitrogen loadings from point and non-point sources are significantly impairing water quality at a large scale and 2) what level of nutrient reductions are necessary to reduce or dominate human impacts to dissolved oxygen levels in the sensitive areas. In this study, an intermediate-scale hydrodynamic model of Puget Sound was developed to simulate the hydrodynamics of Puget Sound and the Northwest Straits for the year 2006. The model was constructed using the unstructured Finite Volume Coastal Ocean Model. The overall model grid resolution within Puget Sound in its present configuration is about 880 m. The model was driven by tides, river inflows, and meteorological forcing (wind and net heat flux) and simulated tidal circulations, temperature, and salinity distributions in Puget Sound. The model was validated against observed data of water surface elevation, velocity, temperature, and salinity at various stations within the study domain. Model validation indicated that the model simulates tidal elevations and currents in Puget Sound well and reproduces the general patterns of the temperature and salinity distributions.

SANSMIC Validation.  

SciTech Connect (OSTI)

SANSMIC is solution mining software that was developed and utilized by SNL in its role as geotechnical advisor to the US DOE SPR for planning purposes. Three SANSMIC leach modes - withdrawal, direct, and reverse leach - have been revalidated with multiple test cases for each mode. The withdrawal mode was validated using high quality data from recent leach activity while the direct and reverse modes utilized data from historical cavern completion reports. Withdrawal results compared very well with observed data, including the location and size of shelves due to string breaks with relative leached volume differences ranging from 6 - 10% and relative radius differences from 1.5 - 3%. Profile comparisons for the direct mode were very good with relative leached volume differences ranging from 6 - 12% and relative radius differences from 5 - 7%. First, second, and third reverse configurations were simulated in order to validate SANSMIC over a range of relative hanging string and OBI locations. The first-reverse was simulated reasonably well with relative leached volume differences ranging from 1 - 9% and relative radius differences from 5 - 12%. The second-reverse mode showed the largest discrepancies in leach profile. Leached volume differences ranged from 8 - 12% and relative radius differences from 1 - 10%. In the third-reverse, relative leached volume differences ranged from 10 - 13% and relative radius differences were ~4 %. Comparisons to historical reports were quite good, indicating that SANSMIC is essentially the same as documented and validated in the early 1980's.

Development of a Hydrodynamic Model of Puget Sound and Northwest Straits  

SciTech Connect (OSTI)

The hydrodynamic model used in this study is the Finite Volume Coastal Ocean Model (FVCOM) developed by the University of Massachusetts at Dartmouth. The unstructured grid and finite volume framework, as well as the capability of wetting/drying simulation and baroclinic simulation, makes FVCOM a good fit to the modeling needs for nearshore restoration in Puget Sound. The model domain covers the entire Puget Sound, Strait of Juan de Fuca, San Juan Passages, and Georgia Strait at the United States-Canada Border. The model is driven by tide, freshwater discharge, and surface wind. Preliminary model validation was conducted for tides at various locations in the straits and Puget Sound using National Oceanic and Atmospheric Administration (NOAA) tide data. The hydrodynamic model was successfully linked to the NOAA oil spill model General NOAA Operational Modeling Environment model (GNOME) to predict particle trajectories at various locations in Puget Sound. Model results demonstrated that the Puget Sound GNOME model is a useful tool to obtain first-hand information for emergency response such as oil spill and fish migration pathways.

Anthropogenic sounds ? Potential effects on fish  

Science Journals Connector (OSTI)

There is concern that human?generated sounds may have deleterious effects on fish. This paper will review some of what is currently known about these effects and consider the questions that have to be answered before developing models to enable "prediction" of sound effects on particular fish species. A major restriction is that there are few peer?reviewed data on effects of anthropogenic sources on fish. Extrapolation from these results is further confounded since experiments differ in many ways each of which may alter the resultant impact on fish. For example studies vary in sounds types tested (e.g. pile driving vs. ship noise) signal parameters (intensity number of repetitions) species used fish age etc. Moreover a singularly important issue is that while many of the issues and impact mechanisms are potentially amenable to experimental lab study the ultimate questions regarding the effects of sound on fish behavior need to field based and require long?term observations where behaviour of wild fish is not constrained. Only by observing fish in the wild will we ultimately understand if and how anthropogenic sounds impact fish both during exposure and more importantly for extended periods after the termination of the sound.

On the Radiation of Sound from an Unflanged Circular Pipe  

Science Journals Connector (OSTI)

A rigorous and explicit solution is obtained for the problem of sound radiation from an unflanged circular pipe, assuming axially symmetric excitation. The solution is valid throughout the wave-length range of dominant mode (plane wave) propagation in the pipe. The reflection coefficient for the velocity potential within the pipe and the power-gain function, embodying the characteristics of the radiation pattern, are evaluated numerically. The absorption cross section of the pipe for a plane wave incident from external space, and the gain function for this direction, are found to satisfy a reciprocity relation. In particular, the absorption cross section for normal incidence is just the area of the mouth. At low frequencies of vibration, the velocity potential within the pipe is the same as if the pipe were lengthened by a certain fraction of the radius and the open end behaved as a loop. The exact value of the end correction turns out to be 0.6133.

Sound Speed Perturbations Due to Internal Tides  

Science Journals Connector (OSTI)

Internal tides are perhaps the most prevalent and largest amplitude internal gravity waves in the ocean. They are commonly generated by the scattering of surfacetidal energy into internal modes when the surfacetides propagate on to continental shelves. A portion of the internal tidal energy propagates into the deep ocean. One of the effects of internal tides on underwater acoustic propagation is to perturb the temperature and salinity versus depth profiles and thus the sound speed versus depth profile. Starting with temperature and salinity versus depth profiles from near Eleuthera Island the internal tide eigenfunctions as well as the sound speed profile have been computed for a water depth of 4500 m. Assuming a value for the vertical displacement amplitude of a first vertical mode internal tide the perturbed temperature and salinity profiles have been computed. From these perturbed profiles the consequent perturbed sound speed profiles have been computed for cases of maximum up and down internal tide displacement. The first mode internal tide has no vertical displacement at the sea surface and bottom and a maximum near the base of the main thermocline (depth of about 1200 m). Since the SOFAR axis is also near the base of the main thermocline and since the pressureeffects on sound speed are predominant below the SOFAR axis the sound speed perturbation due to the first mode internal tide is greatest at a depth (about 550 m) above the SOFAR axis. An internal tide with a maximum vertical displacement of 10 m produces a maximum sound speed perturbation of 0.7 m/sec.

Determination of sound power of coupled machines  

Science Journals Connector (OSTI)

Several procedures are available for the determination of the sound power level of machines in normal environments. Most of these give adequate results for single medium?sized equipment but difficulties arise in extending the concepts to large coupled machines. [Evaluation of Proposed ASME PTC 36 Code for Sound Power Level Determination of Large Steam Turbine Generators S.E. Grabkowski J. MacDonald and T. Van Schaick (General Electric Company) to be presented at Fall 1975 ASME meeting.] Much of the problem is because the direct acoustic field of a component machine may not extend to as much as one foot from its surface due to reverberation from other components. A procedure is suggested in which all acoustic measurements are confined to surfaces near each component machine. Correction is made for the reverberant acoustic field of the entire environment. The correction procedure utilizes reverberation time determinations from impulsive noise tests; and applies a Monte Carlo approach to the problem of correcting for nearfield effects in the evaluation of sound power. An iterative computation is employed. Comparisons with free?field sound power determinations are shown.

Sound radiation measurement with nearfield holography  

Science Journals Connector (OSTI)

With holography an entire 3D wave field can be reconstructed from data obtained on a single 2D surface. Such high information content has made holography a powerful research tool and useful extensions from its original optical domain to other wave fields such as sound have naturally been pursued. However it has usually been assumed that the resolution of a holographicreconstruction is limited by the wavelength of the radiation; this limitation severely diminishes the usefulness of holography for sound fields when the wavelengths are many times larger than the objects to be imaged. We have developed a new technique called nearfield holography which eliminates the wavelength resolution limit and in addition permits a determination of: (1) the complete sound pressure and particle velocity fields produced by the source; (2) the mode of vibration of the surfaces of the source; (3) the vector intensity field (showing flow of acoustic energy) around the source; (4) the farfield directivity pattern; (5) the total power radiated into a half?space. A particularly interesting application of nearfield holography occurs in the study of sound radiation from musical instruments. [Work supported by ONR.

Sound?Power Production in Wind Instruments  

Science Journals Connector (OSTI)

This paper presents data for output sound powerP O of wind instruments relation to input power P I supplied by the player. P I was calculated as pV? where p equals mouth pressure and V? air flow rate through the instrument. P O was calculated from sound?pressure level and measurements of reverberation time in a live room of known volume. A part of the data was obtained in a room of unknown characteristics; from 15 comparable measurements on 8 different instruments in both the live and the unknown room data were obtained that allowed calculation of P O also from other experiments in the unknown room. Measurements were made on single notes played both pp and ff on each instrument; one low and one high note on the scale of each instrument were chosen. The ratio P O/P I representing the mechanical efficiency of wind instruments as sources of sound power varies from less than 0.001% to about 2%. It appears to increase with increasing P I and in some instruments with frequency. The consistent results obtained for 3 different flutes played by one performer suggest that the variability noted in the other data at least partially reflects individual differences in mechanical efficiency.

Sound insulation ratingsthe STC revisited  

Science Journals Connector (OSTI)

About twenty years ago building authorities and their acoustical experts were faced with a confusing variety of schemes for rating the sound insulation of walls and floors. There was need for a definitive rating system that would digest the 16 transmission loss values that characterize a partition and produce a single number that would describe its sound insulation performance especially in respect to multi?family dwellings. Two standards committees ISO/TC 43 and ASTM E6 (now E33) began more or less together to develop a new improved rating system to fill this need. The product of these labors was what is known in North America as the ASTM sound transmission class (STC). This rating system was so successful that it was almost universally adoptedeven in applications for which it was not intended. Despite the apparent success there is now increasing awareness of imperfections in the system. These are examined in light of accumulated data and experience to see whether the system could or should be improved by certain minor changes.

Future directions in impulsive sound sources  

Science Journals Connector (OSTI)

While impulsive acoustic sources have long been used by the geophysical community for underwater exploration sonar applications have been relatively uncommon. Recent work in the area of electric discharge devices has led to both a better understanding of the physics of this class of impulsive soundgenerator and to new devices which may in turn lead to an expanded role for such technology in sonar applicationsin particular the observation that the electric arc commonly associated with sparker sound sources represents a wasteful and unnecessary complication. Proper electrode design and control of the electric discharge can eliminate the arc leaving only a steam bubble and can thereby enhance the low?frequency performance of such a device. Insight into the performance and potential of such devices is in part a result of improved computer modeling capabilities of the nonlinear processes associated with impulsive devices as well as on the use of high?speed data acquisition in interpreting experimental results. This is especially true for determining the effects of interactions in arrays of bubble sources. Beyond the electric discharge sources understanding of the coupling of energy from the bubble to the sound field suggests improvements for chemically driven sound sources as well. An update of work on these impulsive devices and the modeling efforts that support them is presented. The performance of some recently developed devices and the potential for future development will be discussed.

Model Validation Status Review  

SciTech Connect (OSTI)

The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M&O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and engineered barriers, plus the TSPA model itself Description of the model areas is provided in Section 3, and the documents reviewed are described in Section 4. The responsible manager for the Model Validation Status Review was the Chief Science Officer (CSO) for Bechtel-SAIC Co. (BSC). The team lead was assigned by the CSO. A total of 32 technical specialists were engaged to evaluate model validation status in the 21 model areas. The technical specialists were generally independent of the work reviewed, meeting technical qualifications as discussed in Section 5.

Verification and validation benchmarks.  

SciTech Connect (OSTI)

Verification and validation (V&V) are the primary means to assess the accuracy and reliability of computational simulations. V&V methods and procedures have fundamentally improved the credibility of simulations in several high-consequence fields, such as nuclear reactor safety, underground nuclear waste storage, and nuclear weapon safety. Although the terminology is not uniform across engineering disciplines, code verification deals with assessing the reliability of the software coding, and solution verification deals with assessing the numerical accuracy of the solution to a computational model. Validation addresses the physics modeling accuracy of a computational simulation by comparing the computational results with experimental data. Code verification benchmarks and validation benchmarks have been constructed for a number of years in every field of computational simulation. However, no comprehensive guidelines have been proposed for the construction and use of V&V benchmarks. For example, the field of nuclear reactor safety has not focused on code verification benchmarks, but it has placed great emphasis on developing validation benchmarks. Many of these validation benchmarks are closely related to the operations of actual reactors at near-safety-critical conditions, as opposed to being more fundamental-physics benchmarks. This paper presents recommendations for the effective design and use of code verification benchmarks based on manufactured solutions, classical analytical solutions, and highly accurate numerical solutions. In addition, this paper presents recommendations for the design and use of validation benchmarks, highlighting the careful design of building-block experiments, the estimation of experimental measurement uncertainty for both inputs and outputs to the code, validation metrics, and the role of model calibration in validation. It is argued that the understanding of predictive capability of a computational model is built on the level of achievement in V&V activities, how closely related the V&V benchmarks are to the actual application of interest, and the quantification of uncertainties related to the application of interest.

Effective speed of sound in phononic crystals  

E-Print Network [OSTI]

A new formula for the effective quasistatic speed of sound $c$ in 2D and 3D periodic materials is reported. The approach uses a monodromy-matrix operator to enable direct integration in one of the coordinates and exponentially fast convergence in others. As a result, the solution for $c$ has a more closed form than previous formulas. It significantly improves the efficiency and accuracy of evaluating $c$ for high-contrast composites as demonstrated by a 2D example with extreme behavior.

Sound velocity bound and neutron stars  

E-Print Network [OSTI]

It has been conjectured that the velocity of sound in any medium is smaller than the velocity of light in vacuum divided by $\\sqrt{3}$. Simple arguments support this bound in non-relativistic and/or weakly coupled theories. The bound has been demonstrated in several classes of strongly coupled theories with gravity duals and is saturated only in conformal theories. We point out that the existence of neutron stars with masses around two solar masses combined with the knowledge of the equation of state of hadronic matter at "low" densities is in strong tension with this bound.

Sound Absorption in the Pacific Ocean  

Science Journals Connector (OSTI)

The absorption of sound in the Pacific Ocean at a nominal frequency of 75 kHz was measured over a horizontal path at depths of 910 and 3350 m. The results are 20.01.5 dB/km and 13.51.5 dB/km respectively which may be compared to values of 27.3 dB/km and 22.7 dB/km extrapolated from the empirical relation of Schulkin and Marsh. Evidently the useful range of this relation is severely limited. In addition the effect of pressure may be greater than previously suspected.

Quality-Controlled Upper-Air Sounding Dataset for DYNAMO/CINDY/AMIE: Development and Corrections  

SciTech Connect (OSTI)

The upper-air sounding network for DYNAMO (Dynamics of the Madden-Julian Oscillation or MJO) has provided an unprecedented set of observations for studying the MJO over the Indian Ocean (IO) where coupling of this oscillation with deep convection first occurs. With 72 sounding sites and dropsonde data from 13 aircraft mission, the sonde network covers the tropics from Eastern African to the West Pacific. In total nearly 26,000 sondes were collected from this network during the experiments 6-month extended observing period (from October 2011 to March 2012). Slightly more than half of the sondes, collected from 33 sites, are at high vertical resolution. Rigorous post-field phase processing of the sonde data included several levels of quality checks and a variety of corrections which address a number of issues (e.g., daytime dry bias, baseline surface data errors, ship deck-heating effects, artificial dry spikes in slow ascent sondes). Because of the importance of an accurate description of the moisture field in meeting the scientific goals of the experiments, particular attention is given to humidity correction and its validation. The humidity corrections, though small relative to some previous field campaigns, produced high fidelity moisture analyses in which sonde precipitable water compared well with independent estimates. An assessment of model operational analyses moisture using corrected sonde data shows an overall good agreement with the exception at upper-levels where model moisture and clouds are more abundant than the sounding data would indicate.

Localization of sound sources in rooms using an improved version of steered response power algorithm.  

Science Journals Connector (OSTI)

Localization of sound sources inside a room is a challenging problem. The possible applications involving speech?based source localization systems range from teleconferencing to home automation systems. For example the localization of a speaker inside a conference room can be very useful to place the speaker in a remote room by means of a spatial audio reproduction system. Also new applications will appear in home automation if accurate source localization systems are available in the future. One of the most robust approaches to source localization is the SRP?PHAT algorithm which has shown to provide very good localization results inside rooms with moderate reverberation. However the computational cost is highly dependent on the spatial sampling and the number of microphones making very difficult the localization of sound events if a coarse spatial sampling is used. In this paper we propose an improvement of this method where sound events are not missed even if a very coarse grid is used. The improvement is based on a previous calculation of the existent cross?correlation lags between spatially adjacent points in the grid assuring that the non?sampled space is covered in terms of cross?correlation lags between microphone pairs when running the algorithm. Several experiments conducted in different rooms with complex acoustics confirm the validity and benefits of the proposed method.?

Pitch Perception of Complex Sounds: Nonlinearity Revisited  

E-Print Network [OSTI]

The ability of the auditory system to perceive the fundamental frequency of a sound even when this frequency is removed from the stimulus is an interesting phenomenon related to the pitch of complex sounds. This capability is known as ``residue'' or ``virtual pitch'' perception and was first reported last century in the pioneering work of Seebeck. It is residue perception that allows one to listen to music with small transistor radios, which in general have a very poor and sometimes negligible response to low frequencies. The first attempt, due to Helmholtz, to explain the residue as a nonlinear effect in the ear considered it to originate from difference combination tones. However, later experiments have shown that the residue does not coincide with a difference combination tone. These results and the fact that dichotically presented signals also elicit residue perception have led to nonlinear theories being gradually abandoned in favour of central processor models. In this paper we use recent results from the theory of nonlinear dynamical systems to show that physical frequencies produced by generic nonlinear oscillators acted upon by two independent periodic excitations can reproduce with great precision most of the experimental data about the residue without resorting to any kind of central processing mechanism.

ENERGY CONSERVATION AND GRAVITY WAVES IN SOUND-PROOF TREATMENTS OF STELLAR INTERIORS. PART I. ANELASTIC APPROXIMATIONS  

SciTech Connect (OSTI)

Typical flows in stellar interiors are much slower than the speed of sound. To follow the slow evolution of subsonic motions, various sound-proof equations are in wide use, particularly in stellar astrophysical fluid dynamics. These low-Mach number equations include the anelastic equations. Generally, these equations are valid in nearly adiabatically stratified regions like stellar convection zones, but may not be valid in the sub-adiabatic, stably stratified stellar radiative interiors. Understanding the coupling between the convection zone and the radiative interior is a problem of crucial interest and may have strong implications for solar and stellar dynamo theories as the interface between the two, called the tachocline in the Sun, plays a crucial role in many solar dynamo theories. Here, we study the properties of gravity waves in stably stratified atmospheres. In particular, we explore how gravity waves are handled in various sound-proof equations. We find that some anelastic treatments fail to conserve energy in stably stratified atmospheres, instead conserving pseudo-energies that depend on the stratification, and we demonstrate this numerically. One anelastic equation set does conserve energy in all atmospheres and we provide recommendations for converting low-Mach number anelastic codes to this set of equations.

Thermo-acoustic Sound Generation in the Interaction of Pulsed Proton and Laser Beams with a Water Target  

E-Print Network [OSTI]

The generation of hydrodynamic radiation in interactions of pulsed proton and laser beams with matter is explored. The beams were directed into a water target and the resulting acoustic signals were recorded with pressure sensitive sensors. Measurements were performed with varying pulse energies, sensor positions, beam diameters and temperatures. The obtained data are matched by simulation results based on the thermo-acoustic model with uncertainties at a level of 10%. The results imply that the primary mechanism for sound generation by the energy deposition of particles propagating in water is the local heating of the medium. The heating results in a fast expansion or contraction and a pressure pulse of bipolar shape is emitted into the surrounding medium. An interesting, widely discussed application of this effect could be the detection of ultra-high energetic cosmic neutrinos in future large-scale acoustic neutrino detectors. For this application a validation of the sound generation mechanism to high accur...

Sound power level measurement of Sheng, a Chinese wind instrument  

Science Journals Connector (OSTI)

Sheng is one of the Chinese traditional wind instruments. But its sound power level has never been carefully measured. In this paper the sound powermeasurements of Sheng were performed for the first time in a reverberation chamber according to ISO standard and Chinese national standard. Two qualified musicians performed on their own instruments in the center of the reverberation chamber. The radiated sound energy and the dynamic ranges of the Sheng were investigated by four channel acoustic measuring equipments. Typical sound power values were obtained through averaging and the results were reported in this paper. It was showed that the mean forte sound power level can reach up to 98dB with a dynamic range of 22.5dB when music scale was performed. The method discussed here is valuable for the sound powermeasurements of other musical instruments. The measurement of the sound power radiated by national musical instruments lays foundations for the investigation into the acoustics of national music halls.

Sound quality descriptors for HVAC equipment from ARI Standards  

Science Journals Connector (OSTI)

The Air Conditioning and Refrigeration Institute (ARI) has several standards that provide methods to evaluate the sound quality of heating ventilating and air?conditioning (HVAC) equipment. These include Standard 270 Sound rating of outdoor unitary equipment Standard 350 Sound rating of non?ducted indoor air?conditioning equipment and Standard 1140P Procedures for evaluating sound quality of HVAC equipment. The preferred method in these standards is best described in Standard 1140P which uses one?third octave band sound power levels that are weighted to adjust for the sensitivity to frequency distribution and presence of tones and are then converted to a single number sound quality indicator. The tone adjustment is based on the projection of a given one?third octave band level relative to the average of the adjacent one?third octave bands. An alternate use of Zwicker method B to determine loudness and loudness level is also provided in ARI Standard 1140P. These standards provide a convenient method by which complex sounds for similar products may be compared.

Sound propagation conditions in the equatorial South Pacific Ocean  

Science Journals Connector (OSTI)

A major part of the South Pacific Ocean is impacted by a cold water circulation induced by the Antarctic Circumpolar Current. This results in either a double or a very broad deep sound channel axis [R. N. Denham et al. J. Acoust. Soc. Am. 81 787789 (1987)]. However nearer the equator this impact is reduced and a series of equatorial currents and counter currents come into play. An analysis is made of existing oceanographic data to determine the resulting sound?speed profile shape and sound channel axis depth. A comparison is made to profiles from the temperate regions of the South Pacific Ocean.

Design and implementation of an underwater sound recording device  

SciTech Connect (OSTI)

The purpose of this study was to design and build two versions of an underwater sound recording device. The device designed is referred to as the Underwater Sound Recorder (USR), which can be connected to one or two hydrophones or other underwater sound sensors. The URS contains a 26 dB preamplifier and a user selectable gain that permits additional amplification of input to the system from 26 dB to 46 dB. Signals within the frequency range up to 15 kHz may be recorded using the USR. Examples of USR applications are monitoring underwater processes that have the potential to create large pressure waves that could potentially harm fish or other aquatic life, such as underwater explosions or pile driving. Additional applications are recording sound generated by vessels or the vocalizations of some marine mammals, such as the calls from many species of whales.

Puget Sound area electric reliability plan  

SciTech Connect (OSTI)

Various conservation, load management, and fuel switching programs were considered as ways to reduce or shift system peak load. These programs operate at the end-use level, such as residential water heat. Figure D-1a shows what electricity consumption for water heat looks like on normal and extreme peak days. Load management programs, such as water heat control, are designed to reduce electricity consumption at the time of system peak. On the coldest day in average winter, system load peaks near 8:00 a.m. In a winter with extremely cold weather, electricity consumption increases fr all hours, and the system peak shifts to later in the morning. System load shapes in the Puget Sound area are shown in Figure D-1b for a normal winter peak day (February 2, 1988) and extreme peak day (February 3, 1989). Peak savings from any program are calculated to be the reduction in loads on the entire system at the hour of system peak. Peak savings for all programs are measured at 8:00 a.m. on a normal peak day and 9:00 a.m. on an extreme peak day. On extremely cold day, some water heat load shifts to much later in the morning, with less load available for shedding at the time of system peak. Models of hourly end-use consumption were constructed to simulate the impact of conservation, land management, and fuel switching programs on electricity consumption. Javelin, a time-series simulating package for personal computers, was chosen for the hourly analysis. Both a base case and a program case were simulated. 15 figs., 7 tabs.

The Puget Sound Area Electric Reliability Plan Draft Environmental Impact Statement (DEIS) identifies the alternatives for solving a power system problem in the Puget Sound area. This Plan is undertaken by Bonneville Power Administration (BPA), Puget Sound Power & Light, Seattle City Light, Snohomish Public Utility District No. 1 (PUD), and Tacoma Public Utilities. The Plan consists of potential actions in Puget Sound and other areas in the State of Washington. A specific need exists in the Puget Sound area for balance between east-west transmission capacity and the increasing demand to import power generated east of the Cascades. At certain times of the year, there is more demand for power than the electric system can supply in the Puget Sound area. This high demand, called peak demand, occurs during the winter months when unusually cold weather increases electricity use for heating. The existing power system can supply enough power if no emergencies occur. However, during emergencies, the system will not operate properly. As demand grows, the system becomes more strained. To meet demand, the rate of growth of demand must be reduced or the ability to serve the demand must be increased, or both. The plan to balance Puget Sound`s power demand and supply has these purposes: The plan should define a set of actions that would accommodate ten years of load growth (1994--2003). Federal and State environmental quality requirements should be met. The plan should be consistent with the plans of the Northwest Power Planning Council. The plan should serve as a consensus guideline for coordinated utility action. The plan should be flexible to accommodate uncertainties and differing utility needs. The plan should balance environmental impacts and economic costs. The plan should provide electric system reliability consistent with customer expectations. 29 figs., 24 tabs.

Increasing the efficiency of thermoacoustic carbon nanotube sound projectors  

Science Journals Connector (OSTI)

Carbon nanotubes (CNTs) can generate smooth-spectra sound emission over a wide frequency range (1105Hz) by means of thermoacoustics (TA). However, in the low frequencies f, where the need for large area sound projectors is high, the sound generation efficiency ? of open CNT sheets is low, since ??f2. Together with this problem, the nanoscale thickness of CNT sheets, their high sensitivity to the environment and the high surface temperatures useful for TA sound generation are other drawbacks, which we address here by protective encapsulation of free-standing CNT sheets in inert gases. We provide an extensive experimental study of such closed systems for different thermodynamic regimes and rationalize our observations within a basic theoretical framework. The observed sound pressure levels for encapsulated argon filled TA transducers (130dB in air and 200dB underwater in the near field at 5cm distance, and 100 and 170dB in the far field at 1m distance) are Q times higher than those for open systems, where Q is the resonant quality factor of the thin enclosure plates. Moreover, the sound generation efficiency of the encapsulated system increases toward low frequencies (??1/f2). Another method to increase ? in the low frequency region is by modulation of the applied high frequency carrier current with a low frequency resonant envelope. This approach enables sound generation at the frequency of the applied current without the need for additional energy-consuming biasing. The acoustical and geometrical parameters providing further increases in efficiency and transduction performance for resonant systems are discussed.

Sound Waves in the Atmosphere at Infrasonic Frequencies  

Science Journals Connector (OSTI)

Various geophysical processes generate sound waves in the atmosphere. Some typical sources are auroral discharges in the upper atmosphere tornadoes and severe storms surface waves on the oceans volcanic explosions earthquakes and atmospheric oscillations arising from unstable wind flow at the tropopause. Man?made sources include powerful explosions and the shock waves from vehicles moving at supersonic speeds at altitudes below about 125 km. The components of sound?wave energy at infrasonic frequencies (oscillation periods >1.0 sec) are propagated for large distances (thousands of kilometers) over the earth's surface with very little loss of energy from absorption by viscosity and heat conduction. But the propagation depends strongly on (a) the horizontally stratified temperature structure of the atmosphere (b) the influence of gravity at oscillation periods greater than the atmospheric resonance period ?300 sec and (c) the nonuniform distribution of atmospheric winds. The microphones and electroacoustical apparatus at an infrasonics observation station e.g. the one at Washington D. C. measure (1) the amplitude and waveform of incident sound pressure (2) the direction of local propagation of the wave (3) the horizontal trace velocity and (4) the distribution of sound wave energy at various oscillation frequencies. Researches on propagation require observational data from a network of stations separated geographically by large distances coupled with theoretical analysis of sound propagation to arrive at useful results on the acoustics of the atmosphere.

Airborne sound propagation over sea during offshore wind farm piling  

Science Journals Connector (OSTI)

Offshore piling for wind farm construction has attracted a lot of attention in recent years due to the extremely high noise emission levels associated with such operations. While underwater noise levels were shown to be harmful for the marine biology the propagation of airborne piling noise over sea has not been studied in detail before. In this study detailed numerical calculations have been performed with the Green's Function Parabolic Equation (GFPE) method to estimate noise levels up to a distance of 10?km. Measured noise emission levels during piling of pinpiles for a jacket-foundation wind turbine were assessed and used together with combinations of the sea surface state and idealized vertical sound speed profiles (downwind sound propagation). Effective impedances were found and used to represent non-flat sea surfaces at low-wind sea states 2 3 and 4. Calculations show that scattering by a rough sea surface which decreases sound pressure levels exceeds refractive effects which increase sound pressure levels under downwind conditions. This suggests that the presence of wind even when blowing downwind to potential receivers is beneficial to increase the attenuation of piling sound over the sea. A fully flat sea surface therefore represents a worst-case scenario.

Improving sound propagation modeling for wind power projects  

Science Journals Connector (OSTI)

Sound propagation from wind power projects can be modeled in the same manner as other more common outdoor noisesources but are these models suited to wind turbines' uniquely high source heights operating under high wind conditions and various degrees of terrain ruggedness. In "Propagation Modeling Parameters for Wind Turbines" (K. Kaliski and E.

Sound emission from the gas of molecular superrotors  

E-Print Network [OSTI]

We use an optical centrifuge to deposit a controllable amount of rotational energy into dense molecular ensembles. Subsequent rotation-translation energy transfer, mediated by thermal collisions, results in the localized heating of the gas and generates strong sound wave, clearly audible to the unaided ear. For the first time, the amplitude of the sound signal is analyzed as a function of the experimentally measured rotational energy. The proportionality between the two experimental observables confirms that rotational excitation is the main source of the detected sound wave. As virtually all molecules, including the main constituents of the atmosphere, are amenable to laser spinning by the centrifuge, we anticipate this work to stimulate further development in the area of photo-acoustic control and spectroscopy.

Outdoor sound propagation in the U.S. Civil War  

Science Journals Connector (OSTI)

In a number of major battles in the U.S. Civil War unusual atmospheric acoustics played a major role. In this study the probable causes of the unusual acoustics are given and the resulting effect on military command decisions is described. The causes discussed include sound absorption wind shear temperature gradients and combinations of these. Several cases will also be described in which multiple ground reflections caused sounds of battle to be heard at unusually great distances. The battles studied include Gettysburg Seven Pines Perryville Iuka Fort Donelson Gaines Mill Five Forks and Chancellorsville.

Metric approach for sound propagation in nematic liquid crystals  

E-Print Network [OSTI]

In the eikonal approach, we describe sound propagation near to topological defects of nematic liquid crystal as geodesics of a non-euclidian manifold endowed with an effective metric tensor. The relation between the acoustics of the medium and this geometrical description is given by Fermat's principle. We calculate the ray trajectories and propose a diffraction experiment to retrieve informations about the elastic constants.

Wind turbine sound prediction - the consequence of getting it wrong  

Science Journals Connector (OSTI)

The application to permit a wind turbine power development usually involves submission of a prediction for the sound level that will occur at residences schools places of worship and elsewhere people gather for restorative rest. This paper uses the example of a wind power development and follows iterations taken to finalize the sound level prediction. The paper provides quantitative information collected since the start up of the wind power development on measured sound levels and octave band distribution; and qualitative observations on the special characteristics of the sound. Actual observations are compared to the predictions. More importantly the paper reviews the consequences self-reported in qualitative interviews by citizens living with the changed environment after four years of operation of the wind power development. Reported impacts included difficulty sleeping loss of jobs and changes to social relationships caregiving pursuit of hobbies leisure learning and overall health. Changes in measured health outcomes are identified. Both the quantitative and qualitative findings justify revision of the permitting process.

The science of underwater sound: Education, communication, and outreach  

Science Journals Connector (OSTI)

As a complex scientific topic underwater sound can be challenging for scientists to discuss and effectively communicate with non-science audiences. Educational audiences span formal K-16 classrooms to museum and aquarium visitors. The science of sound is often included in upper middle school physical sciences curricula high school physics classes and undergraduate and graduate university courses which can take advantage of calculus to support student understanding. Communicating with the media presents other challenges: pressing or immediate deadlines; a need to deliver eye-catching flashy pieces that capture reader attention; and a general lack of fundamental knowledge of underwater sound by readers. Scientists must be proactive in their engagement with media to ensure good fundamental science is communicated and to increase useful stories about new developments in underwater sound research. Regulators and other decision-makers are also pressed for time when contemplating a topic yet they need the most up-to-date scientific findings to support their decision-making. This talk will provide an overview of the challenges that ocean acoustic specialists face when trying to communicate the results of their research and meet the needs of diverse audiences. In addition strategies and possible solutions will be discussed.

On the evolution of controllers for sound spatialization  

Science Journals Connector (OSTI)

Dynamic changes in spatialsound attributes have played a role in classical Western music for a long time. It is known that choreographic movements of operasingers were sometimes made for acoustic considerations. Probably the first mechanical spatialsound controller is the so?called wind swell that is found in pipe organs. Already in 1712 Renatus Harris mentions how swelling enables the player to project the sound of the pipes ad libitum to nearby or further distances. With the invention of electroacoustic music a number of electromechanical devices were developed to control spatial aspects of sound (primarily positioning sound sources in 3?D space). Typical examples are Stockhausens rotational table (developed in the 1950s) and Manfred Krauses sound mill (1960). In this presentation the evolutionary steps in the design of spatialsound controllers will be outlinedbeginning with early purely mechanical devices up to recent approaches including the authors participation in the development of a gestural controllable soundsystem based on virtual microphone control (ViMiC).

Velocity of sound in relativistic heavy-ion collisions  

Science Journals Connector (OSTI)

We have studied the rapidity distribution of secondary hadrons produced in nucleus-nucleus collisions at ultrarelativistic energies within the ambit of the Landaus hydrodynamical model. A reasonable description of the data can also be obtained by using the Bjorkens hydrodynamical model if the boost invariance is restricted to a finite rapidity range. The sensitivity of the hadronic spectra on the equation of state vis--vis the velocity of sound has been discussed. The correlation between the velocity of sound and the freeze-out temperature has been indicated. The effects of the nonzero widths of various mesonic and baryonic degrees of freedom up to the mass value ?2.5GeV are seen to be small.

Processing of prosthetic heart valve sounds for classification. Revision 1  

SciTech Connect (OSTI)

People with serious heart conditions have had their expected life span extended considerably with the development of the prosthetic heart valve especially with the great strides made in valve design. Even though the designs are extremely reliable, the valves are mechanical and operating continuously over a long period, therefore, structural failures can occur due to fatigue. Measuring heart sounds non-invasively in a noisy environment puts more demands on the signal processing to extract the desired signals from the noise. In this paper the authors discuss acoustical signal processing techniques developed to process noisy heart valve sounds measured by a sensitive, surface contact microphone and used for the eventual classification of the valve.

Sound radiation due to rapid deformation of an impacted plate  

Science Journals Connector (OSTI)

Sound radiation due to forced deformation of an impacted plate was investigated. An initial sound pressure pulse due to rapid local deformation of a plate was generated before the radiation from natural modes of the plate occurred. On the axis of impact near the plate a distinct pressure pulse is observed to reproduce the velocity waveform of the plate at the opposite side of the impact point. Data from experiments involving impact of spheres on plates differing in size and material properties are presented to show the plate behavior and the radiated soundpressure. Theoretical results were obtained from an analytical model in which impulsive acceleration of a plate with Gaussian spatial distribution is convoluted with the acceleration?time history of the actual impact. Theoretical results for the on?axis pressure are compared with the experimental results.

Near-Field Imaging with Sound: An Acoustic STM Model  

Science Journals Connector (OSTI)

The invention of scanning tunneling microscopy(STM) 30 years ago opened up a visual window to the nano-world and sparked off a bunch of new methods for investigating and controlling matter and its transformations at the atomic and molecular level.1 However an adequate theoretical understanding of the method is demanding; STM images can be considered quantum theory condensed into a pictorial representation. A hands-on model is presented for demonstrating the imaging principles in introductory teaching. It uses sound waves and computer visualization to create mappings of acoustic resonators. The macroscopic simile is made possible by quantum-classical analogies between matter and sound waves. Grounding STM in acoustic experience may help to make the underlying quantum concepts such as tunneling less abstract to students.

Generation of Sound Bullets with a Nonlinear Acoustic Lens  

E-Print Network [OSTI]

Acoustic lenses are employed in a variety of applications, from biomedical imaging and surgery, to defense systems, but their performance is limited by their linear operational envelope and complexity. Here we show a dramatic focusing effect and the generation of large amplitude, compact acoustic pulses (sound bullets) in solid and fluid media, enabled by a tunable, highly nonlinear acoustic lens. The lens consists of ordered arrays of granular chains. The amplitude, size and location of the sound bullets can be controlled by varying static pre-compression on the chains. We support our findings with theory, numerical simulations, and corroborate the results experimentally with photoelasticity measurements. Our nonlinear lens makes possible a qualitatively new way of generating high-energy acoustic pulses, enabling, for example, surgical control of acoustic energy.

Validation Validation MARMOT Validation January 29, 2013 - 10:35am Addthis The composition-dependent mobility in the formulism of the phase-field modeling is implemented into the MARMOT phase-field algorithm. Benchmarking was done for the MARMOT, finite element (FE)-based phase-field framework that utilizes the new implementation of the variable splitting algorithm. The results indicate that while the variable splitting algorithm executes about eight times faster, the use of higher-order Hermite elements offers faster convergence. A manuscript summarizing these results has been submitted for publication. Work is also continuing on implementing a J2 von-Mises' time-dependent and independent plasticity into the Marmot phase-field algorithm. The current studies do not include adoptive meshing,

Sound speed and thermophysical properties of liquid iron and nickel  

Science Journals Connector (OSTI)

An electrical-pulse-heating technique has been used to heat iron and nickel to high temperatures to measure thermophysical properties in the liquid state. A dynamic technique was used because static techniques, which are capable of greater precision, fail at a relatively low temperature. Measurements have been made, and results are shown for enthalpy, temperature, density, electrical resistivity, and sound speed up to 3950 K in iron and 4250 K in nickel.

Observation of a second-sound-like mode in superfluid-filled aerogel  

Science Journals Connector (OSTI)

Superfluid He4 is interesting acoustically because it can support more than one mode of sound propagation, and these can be used to study critical properties. Recently, there has been interest in superfluid-filled aerogels, but for such compressible materials one does not observe the ordinary (fourth) sound; instead there is a mode intermediate between first and fourth sound and a second-sound-like mode. We present a theory for the modes and the first observation of the aerogel second-sound-like mode, which is important because it propagates near the critical temperature.

Experimental study on sound absorbing performance of rubber crumb  

Science Journals Connector (OSTI)

The present paper describes an experimental campaign aimed at the determination of acoustical properties of vulcanized rubber crumbs obtained by the shredding of used tires. In particular their performance as sound absorbing material in lined ducts was investigated. The most innovative aspect that is addressed in the study is the use of a waste material such as rubber tires reduced into small grains as a sound absorbing material: tires are in fact usually used at the end of their life cycle as fuel and burned in cement kilns in order to take advantage of their high heating value with all the problems of pollution that this solution produces. Two kinds of rubber crumbs have been investigated in terms of characteristic dimension of the grains porosity and sound absorbing coefficient while their "in situ" performance when used inside lined and parallel-baffle rectangular ducts has been evaluated measuring their insertion loss. The results of this research show that the acoustical behaviour of the tested rubber crumbs is the typical behaviour of the granular materials showing a noteworthy performance of the tested material in the low frequency range opening a scenery of possible applications where noise has relevant tonal components below 315 Hz.

Low?frequency sound radiation and scattering from bubble clouds.  

Science Journals Connector (OSTI)

Recent experimental evidence has shown that when wave breaking occurs low?frequency (LF?200 Hz) sound is produced and LF scatter has a different characteristic than expected from rough sea surface scattering. These effects have been attributed to the bubbles produced during wave breaking which are convected to depth by the breaking turbulence vorticity and Langmuir circulation as observed by Thorpe [S. Thorpe Oceanic White Caps edited by E. Monahan and G. MacNiocaill (Reidel Boston 1986) pp. 5758]. While the radiation and scatteringcharacteristics at frequencies greater than 1 kHz are explained by incoherent scatter from the observed bubble size and space distributions the lower frequency phenomena are not easily explained. However if bubble plumes and clouds produced in the wave breaking have appreciable volume fractions (?10?5) then LF sound radiation and scattering can be explained by classical theories. This paper reviews the scattering and radiation from bubbleclouds in water as a function of volume fraction. When the cloud is compact coherent and collective scatter are shown to occur. The natural frequency of radiation is shown to be described by a modified Minnaert result while the backscatter target strength is described by the first?order volume mode. These analytical results agree with experimental sound radiation and scatter measurements. Finally the collective radiation of bubble plumes and clouds is discussed as a possible explanation of the observed ocean low?frequency scattering and radiation phenomena.

Measurement of sound transmission through mud at Dodge Pond, Connecticut.  

Science Journals Connector (OSTI)

Questions important to the sonic detection of buried ordinance are whether the sound dispersion and attenuation of muddy bottoms can be predicted and verified. Wood and Weston [Acustica (1964)] measured compressional speeds in harbor mud 3% less than that of water with attenuation considerably less than those of sandy/silty sediments. A recent theoretical treatment [Pierce and Carey POMA 7001 (2009)] making use of the MallockWood equation and of a card?house theory of the structure of mud estimates the slow sound speed to depend on porosity as 1?(0.35)(1??). Present measurements at frequencies between 1 and 10 kHz with a buried array in the depositional mud at the bottom of Dodge Pond which contains considerable gas microbubbles yield speeds of the order of 60% of the sound speed in water. The initial measurements on the disturbed sediment were found to be strongly influenced by scattering from larger bubbles whereas the results after a period of 10 months showed the effect of a smaller size distribution of bubbles. Estimates based on the Dodge Pondmeasurements and on the card?house theory of the propagation characteristics and of the effect of micro?bubbles are discussed. [Sponsored by SERDP?NSWC?PCD.

Thermoacoustic sound projectors using carbon nanotubes and other nanostructures  

Science Journals Connector (OSTI)

The application of solid-state fabricated carbon nanotube sheets as thermoacoustic (TA) projectors is extended from air to underwater applications. Due to non-resonant sound generation the emission spectrum of nanotube sheets in air or underwater varies smoothly over a wide frequency range 1-105 Hz. Encapsulating the nanotube sheet projectors using inert gases with low heat capacity provided attractive performance at needed low frequencies as well as a realized energy conversion efficiency in air of 0.2% and 1.5% underwater which can be enhanced by further increasing the modulation temperature. We suggest enhancement of sound generation efficiency of encapsulated device by using high quality resonant acoustical windows and modulation of high frequency carrier current with a low frequency resonant envelope. Applications of TA projectors for high power sonar arrays and transparent flexible loudspeakers will be discussed. Finally the alternative nanostructures for excitation of thermoacoustic sound waves will be surveyed. [We gratefully acknowledge support by Office of Naval Research grant N00014-13-1-0180.

Model Validation with Hybrid Dynamic Simulation  

SciTech Connect (OSTI)

AbstractModel validation has been one of the central topics in power engineering studies for years. As model validation aims at obtaining reasonable models to represent actual behavior of power system components, it has been essential to validate models against actual measurements or known benchmark behavior. System-wide model simulation results can be compared with actual recordings. However, it is difficult to construct a simulation case for a large power system such as the WECC system and to narrow down to problematic models in a large system. Hybrid dynamic simulation with its capability of injecting external signals into dynamic simulation enables rigorous comparison of measurements and simulation in a small subsystem of interest. This paper presents such a model validation methodology with hybrid dynamic simulation. Two application examples on generator and load model validation are presented to show the validity of this model validation methodology. This methodology is further extended for automatic model validation and dichotomous subsystem model validation.

Electromagnetic soundings over a geothermal reservoir in Dixie Valley, Nevada  

SciTech Connect (OSTI)

An electromagnetic (EM) sounding survey was performed over a region encompassing the Dixie Valley geothermal field with the purpose of mapping the subsurface resistivity in the geothermal field and its surroundings. The EM survey consisted of 19 frequency-domain depth soundings made with the EM-60 system using three separate horizontal-loop transmitters, and was designed to explore a narrow region adjacent to the Stillwater Range to a depth of 2 to 3 k. Most sounding curves could be fitted to three-layer resistivity models. The surface layer is moderately conductive (10 to 15 ohm-m), has a maximum thickness of 500 m, and consists mainly of alluvial fan and lake sediments. More conductive zones are associated with hydrothermally altered rocks; a resistivity high may be associated with siliceous hot spring deposits. The conductive second layer (2 to 5 ohm-m) varies in thickness from 400 to 800 m and thickens toward the center of the valley. This layer probably consists of lacustrine sediments saturated with saline waters. Local resistivity lows observed in the second layer may be related to elevated subsurface temperatures. This layer may act as a cap rock for the geothermal system. Resistivities of the third layer are high (50 to 100 ohm-m) except in a narrow 5-km band paralleling the range front. This low-resistivity zone, within volcanic rocks, correlates well in depth and location with reported zones of geothermal fluid production. It also seems to correlate with the western margin of a concealed graben structure previously inferred from other geophysical data.

On Heating of Cluster Cooling Flows by Sound Waves  

E-Print Network [OSTI]

We investigate heating of the cool core of a galaxy cluster through the dissipation of sound waves excited by the activities of the central active galactic nucleus (AGN). Using a weak shock theory, we show that this heating mechanism alone cannot reproduce observed temperature and density profiles of a cluster, because the dissipation length of the waves is much smaller than the size of the core and thus the wave energy is not distributed to the whole core. However, we find that if it is combined with thermal conduction from the hot outer layer of the cluster, the wave heating can reproduce the observational results.

Spatial coherence measurement of sound in the northwest Pacific Ocean  

Science Journals Connector (OSTI)

An experiment on the transverse horizontal spatial coherence of sound propagating in the ocean was performed jointly by Chinese and Russian acousticians in the northwest Pacific Ocean in June 1990. Three hydrophones with spacings of 270 and 130 m were put in the water at a 30?m depth. The acoustic source with four cw (from 109 to 860 Hz) and a broadband pseudorandom noise signal was drifted at a depth of 100 m. Part of the measurement results of up to 140 km are presented in this paper. It seems that the spatial coherence was related to the amplitude of the received signals and rises considerably in convergence zones.

Zero sound modes of dilute Fermi gases with arbitrary spin  

Science Journals Connector (OSTI)

Motivated by the recent success of optical trapping of alkali-metal bosons, we have studied the zero sound modes of dilute Fermi gases with arbitrary spin-f, which are spin-S excitations (0<~S<~2f). The dispersion of the mode (S) depends on a single Landau parameter F(S), which is related to the scattering lengths of the system through a simple formula. Measurement of (even a subset of) these modes in finite magnetic fields will enable one to determine all the interaction parameters of the system.

The sound quality of vehicle interior noise: a challenge for the NVH-engineers  

Science Journals Connector (OSTI)

The sound quality of vehicle interior noise has become a very important task for the acoustic engineers since more than 20 years. As vehicles become more and more quiet, the customer's sensitiveness for the acoustical comfort increases. On the one hand, no disturbing noises should be heard and on the other hand, the perceived sound quality, for example from the powertrain, should fulfill the expectations of the listener with respect to the sound design. The development of a good sound quality is in conflict with other targets. The development time of a new car has to be reduced and the production costs have to be lower, the total weight of the car should not increase ?? without any negative influence on the sound quality. For the acoustical engineer it becomes important to know what kind of tools are available to measure, to analyse and to describe sound quality on the one hand and how to improve it on the other hand.

Underwater and in-air sounds from a small hovercraft  

Science Journals Connector (OSTI)

Underwater and in-air recordings were made from a boat anchored near Prudhoe Bay Alaska while a Griffon 2000TD hovercraft drove by at or near full power on four passes. At the closest point of approach (CPA 6.5 m ) underwater broadband ( 10 10 000 Hz ) levels reached 133 and 131 dB re : 1 ? Pa at depths of 1 and 7 m respectively. In-air unweighted and A-weighted broadband ( 10 10 000 Hz ) levels reached 104 and 97 dB re : 20 ? Pa respectively. The hovercraft produced sound at a wide range of frequencies. Both underwater and in air the largest spectral peak was near 87 Hz which corresponded to the blade rate of the thrust propeller. In addition the spectral composition included several harmonics of this frequency. The shaft or blade rate of the lift fan was barely detectable underwater despite its proximity to the water. The hovercraft was considerably quieter underwater than similar-sized conventional vessels and may be an attractive alternative when there is concern over underwater sounds.

Assessment of HVAC sound power data for sensitive spaces.  

Science Journals Connector (OSTI)

Certification testing of air handling unit sound power (PWL) indicates that individual unit PWL can vary significantly from manufacturer published data. Published data are typically based on a limited number of actual tests with results extrapolated for other fan sizes and operating conditions. Although published data are normally acceptable for routine applications indiscriminate use for sensitive designs (studios theaters conference centers etc.) can result in excessive finished space noise levels. The fact that the design goals have been exceeded can be accurately documented. The exact reason for the exceedance however cannot be as firmly established in a complex system. Certification PWL testing of air handling units prior to installation can detect PWL variations from the published data. Individual unit PWL certification was often not cost effective prior to the developement of sound intensity and the establishment and use of recognized standards for in situ PWL testing (e.g. ASA 104?1992 ANSI S.12.12.1992). Case histories to be presented document fan PWL variations from published data of up to 10 dB and higher in certain octave bands.

Air handler sound power prediction method based on ARI Standard 260  

Science Journals Connector (OSTI)

A method of predicting air handler sound power based on ratings for a product line is described. The method provides octave band sound power levels based on ratings obtained using Air?Conditioning and Refrigeration Institute (ARI) Standard 260 Sound Rating Of Ducted Air Moving And Conditioning Equipment. Detailed sound power information for HVAC equipment is not always available but it is important in accurately predicting noise levels in acoustically sensitive spaces. To address this need a rating program was undertaken using ARI 260. This standard is a reverberant room technique for sound rating ducted air conditioning equipment using a reference sound source substitution method. Since sound travels from the source to receiver along numerous paths this standard differentiates between sound power emanating from several common paths called components. Components for this project included ducted discharge free inlet plus casing ducted inlet and casing. The standard provides guidance on adequate number of fan sizes appurtenances and operating characteristics. The intent of the project was to provide a model to predict sound power by unit size component operating condition and unit configuration. Good agreement was found between predicted levels and measured data.

ALEGRA-HEDP validation strategy.  

SciTech Connect (OSTI)

This report presents a initial validation strategy for specific SNL pulsed power program applications of the ALEGRA-HEDP radiation-magnetohydrodynamics computer code. The strategy is written to be (1) broadened and deepened with future evolution of particular specifications given in this version; (2) broadly applicable to computational capabilities other than ALEGRA-HEDP directed at the same pulsed power applications. The content and applicability of the document are highly constrained by the R&D thrust of the SNL pulsed power program. This means that the strategy has significant gaps, indicative of the flexibility required to respond to an ongoing experimental program that is heavily engaged in phenomena discovery.

Benchmarks for GADRAS performance validation.  

SciTech Connect (OSTI)

The performance of the Gamma Detector Response and Analysis Software (GADRAS) was validated by comparing GADRAS model results to experimental measurements for a series of benchmark sources. Sources for the benchmark include a plutonium metal sphere, bare and shielded in polyethylene, plutonium oxide in cans, a highly enriched uranium sphere, bare and shielded in polyethylene, a depleted uranium shell and spheres, and a natural uranium sphere. The benchmark experimental data were previously acquired and consist of careful collection of background and calibration source spectra along with the source spectra. The calibration data were fit with GADRAS to determine response functions for the detector in each experiment. A one-dimensional model (pie chart) was constructed for each source based on the dimensions of the benchmark source. The GADRAS code made a forward calculation from each model to predict the radiation spectrum for the detector used in the benchmark experiment. The comparisons between the GADRAS calculation and the experimental measurements are excellent, validating that GADRAS can correctly predict the radiation spectra for these well-defined benchmark sources.

Dispersal of measured sound power levels for wind turbines  

Science Journals Connector (OSTI)

The standard IEC 61400?11 provides guidance in the measurement analysis and reporting of acoustic emissions(sound power levels) from wind turbine generator systems. The application of this standard aims to provide accurate results that can be replicated by others. We did several measurement operations according to this standard on various wind farms fitted with many turbine manufacturers on different ground types. Important differences have been noticed with equal working conditions between the most and the less noisy wind turbine on a single farm. We will present these results compared to the manufacturers' guaranteed values and initiate explanations (like the difficulties to link the wind speed at 10m above ground with the wind speed received at hub height; or the influence of wind incidence on blades).

The CSULB Mobile Science Museum: Sights and sounds of science  

Science Journals Connector (OSTI)

In 1980 a 27?ft recreational vehicle was adapted to carry interactive science displays to local schools and community groups. This Mobile Science Museum (MSM) exhibits as many as 40 individual hands?on displays both inside as well as on tables directly outside the vehicle. University science students serve as docents and pass on their enthusiasm for science while providing role models for young visitors. Most displays are borrowed from university science teaching and research laboratories while others are developed and fabricated by faculty staff and students. Topics found to be particularly effective for presentation in the hands?on mode include sound light and marine biology. Far more schools request visits by the MSM than can be served within current budgetary constraints. While this project is supported by CSULB School of Natural Sciences the majority of the operating budget comes from other sources of funding including companies specializing in science and technology school districts parent/teacher associations and private individuals.

Sound transmission loss of nontraditional building materials and redundancies  

Science Journals Connector (OSTI)

This line of inquiry aims to provide sound transmission loss data both lab? and field?tested for novel transparent and translucent wall assemblies. Special attention is paid to: (1) Redundant assemblies featuring two layers of material with a large gap or small room between them (2) assemblies featuring emerging materials and (3) assemblies with high thermal resistance values. To that end composite configurations of acrylic polycarbonate aerogel and glass were tested in a laboratory and an acrylic room and glass vestibule were tested in the field. Results will be presented with an eye toward future use of the data. Indeed it was the unavailability of the data in existing publications that initially drove the research.

Pressure dependence of sound attenuation in the Pacific Ocean  

Science Journals Connector (OSTI)

Measurements of the attenuation of sound at a nominal frequency of 75 kHz have been made over vertical and horizontal acoustic paths located between depths of 700 and 3400 m in the Pacific Ocean. Results indicate that the equation used to predict attenuation overestimates the values actually encountered at these frequencies and depths. (Compare calculated values of 27.3 and 22.7 dB/km to measured values of 19.90.5 and 13.30.5 dB/km at depths of 910 and 3350 m respectively.) The measurements definitely establish the decrease of attenuation with increasing pressure. However the magnitude of the pressure coefficient of attenuation is almost twice as large as previously suspected (12.31.110?4/bar or approximately 12.310?4/atm compared to 6.5410?4/atm).

Model Validation with Hybrid Dynamic Simulation  

SciTech Connect (OSTI)

AbstractModel validation has been one of the central topics in power engineering studies for years. As model validation aims at obtaining reasonable models to represent actual behavior of power system components, it has been essential to validate models against actual measurements or known benchmark behavior. System-wide model simulation results can be compared with actual recordings. However, it is difficult to construct a simulation case for a large power system such as the WECC system and to narrow down to problematic models in a large system. Hybrid dynamic simulation with its capability of injecting external signals into dynamic simulation enables rigorous comparison of measurements and simulation in a small subsystem of interest. This paper presents such a model validation methodology with hybrid dynamic simulation. Two application examples on generator and load model validation are presented to show the validity of this model validation methodology. This methodology is further extended for automatic model validation and dichotomous subsystem model validation. A few methods to define model quality indices have been proposed to quantify model error for model validation criteria development.

Processing of prosthetic heart valve sounds for single leg separation classification  

SciTech Connect (OSTI)

Efforts are concentrated on the sounds corresponding to the heart valve opening cycle. Valve opening and closing acoustics present additional information about the outlet strut condition---the structural component implicated in valve failure. The importance of the opening sound for single leg separation detection/classification is based on the fact that as the valve opens, the disk passively hits the outlet strut. The opening sounds thus yield direct information about outlet strut condition with minimal amount of disturbance caused by the energy radiated from the disk. Hence the opening sound is a very desirable acoustic signal to extract. Unfortunately, the opening sounds have much lower signal levels relative to the closing sounds and therefore noise plays a more significant role than during the closing event. Because of this it is necessary to screen the sounds for outliers in order to insure a high sensitivity of classification. Because of the sharp resonances appearing in the corresponding spectrum, a parametric processing approach is developed based on an autoregressive model which was selected to characterize the sounds emitted by the Bjork--Shiley convexo--concave (BSCC) valve during opening cycle. First the basic signals and the extraction process used to create an ensemble of heart valve sounds are briefly discussed. Next, a {ital beat} {ital monitor} capable of rejecting beats that fail to meet an acceptance criteria based on their spectral content is developed. Various approaches that have been utilized to enhance the screened data and produce a reliable {ital heart} {ital valve} {ital spectrogram} which displays the individual sounds (power) as a function of beat number and temporal frequency are discussed. Once estimated, the spectrogram and associated parameters are used to develop features supplied to the various classification schemes. Finally, future work aimed at even further signal enhancement and improved classifier performance is discussed.

System and method for characterizing, synthesizing, and/or canceling out acoustic signals from inanimate sound sources  

DOE Patents [OSTI]

A system and method for characterizing, synthesizing, and/or canceling out acoustic signals from inanimate sound sources is disclosed. Propagating wave electromagnetic sensors monitor excitation sources in sound producing systems, such as machines, musical instruments, and various other structures. Acoustical output from these sound producing systems is also monitored. From such information, a transfer function characterizing the sound producing system is generated. From the transfer function, acoustical output from the sound producing system may be synthesized or canceled. The methods disclosed enable accurate calculation of matched transfer functions relating specific excitations to specific acoustical outputs. Knowledge of such signals and functions can be used to effect various sound replication, sound source identification, and sound cancellation applications.

Structural-borne sound mitigation in small wind turbines using constrained viscoelastic layer  

Science Journals Connector (OSTI)

As the growing acceptance of small wind turbines operating in suburban and rural communities coincides with increasingly stringent regulations on the sound emitted by these turbines the need for sound mitigation solutions becomes urgent. Small turbines need to be affordable for small business use and thus proposed solutions must be cost-effective and low maintenance. Easy retrofit to existing turbines is also desirable. Wind turbines generate sound via two main mechanisms: structural borne sound generated by the gearbox and generator and transmitted through the nacelle structure and aeroacoustic sound generated by the interaction of the airstream with the rotating blades and other turbine components. Current study focused on the mitigation of structural-borne sound in a 50 kW wind turbine using a constrained viscoelastic layer. The viscoelastic layer comprised of multiple tiles with normal force to the nacelle structure provided by ratcheting bands. Optimal value for the normal force was empirically determined and the resulting reductions in generated sound were documented both in the laboratory and on a working turbine under a number of operating conditions. The result is a cost-effective solution with zero cost of ownership and easy installation on a wide range of small to medium-size wind turbines.

Auralization of urban soundscaping designs using the Arup SoundLab  

Science Journals Connector (OSTI)

Noise is unwanted sound (from an urban planning point of view). The standard practice to controlnoise while valuable is a negative process (i.e. reducing unwanted noise). In response there is a drive by several authorities to take a more positive approach to improve and manage soundscapes in cities and civic spaces. Urban soundscape design consists of planning shaping and managing the sound to fit each area of the masterplan in terms of civic cultural and social character. Arup uses its SoundLab a 3D sound facility (ambisonic) to design and auralise (the sound equivalent to visualisation) soundscapes with planners architects or artists and demonstrate to Local Planning Authorities or clients the results of the design. An example of urban soundscaping design is Dark Neville Street Leeds for Leeds City Council where architectural lighting design acoustical soundscaping design were integrated together with an artistic sonic piece by Hans?Peter Kuhn which was auralised in the Arup SoundLab. An example of indoor sonic art and soundscape design installation is Harmonic Bridge by Bill Fontana and Arup Acoustics in the Turbine Hall of the Tate Modern (June?August 2006) where the sonic art piece was composed in the SoundLab.

Sound insulation property of Al-Si closed-cell aluminum foam bare board material  

Science Journals Connector (OSTI)

A1-Si closed-cell aluminum foam bare boards of 1?240 mm1?100 mm with different densities and thicknesses were prepared by molten body transitional foaming process. The sound reduction index(R) of AI-Si closed-cell aluminum foam bare boards was investigated experimentally under different frequencies (100-4?000 Hz). It is found that sound reduction index(R) is small under low frequencies, large under high frequencies and is controlled by different mechanisms. The sound insulation property basically conforms with the monolayer board sound insulation theory. The sound reduction index(R) increases with the even growth of thickness and density, but its rising trend is tempered. The single number sound reduction indexes(Rw) of specimen with thickness of 20 cm and density of 0.51 g/cm3 are 30.8 dB and 33 dB respectively, which demonstrates good sound insulation property for lightmass materials.

Covariance of dark energy parameters and sound speed constraints from large HI surveys  

E-Print Network [OSTI]

An interesting probe of the nature of dark energy is the measure of its sound speed, $c_s$. We review the significance for constraining sound speed models of dark energy using large neutral hydrogen (HI) surveys with the Square Kilometre Array (SKA). Our analysis considers the effect on the sound speed measurement that arises from the covariance of $c_s$ with the dark energy density, $\\Omega_\\LLambda$, and a time-varying equation of state, $w(a)=w_0+(1-a)w_a$. We find that the approximate degeneracy between dark energy parameters that arises in power spectrum observations is lifted through redshift tomography of the HI-galaxy angular power spectrum, resulting in sound speed constraints that are not severely degraded. The cross-correlation of the galaxy and the integrated Sachs-Wolfe (ISW) effect spectra contributes approximately 10 percent of the information that is needed to distinguish variations in the dark energy parameters, and most of the discriminating signal comes from the galaxy auto-correlation spectrum. We also find that the sound speed constraints are weakly sensitive to the HI bias model. These constraints do not improve substantially for a significantly deeper HI survey since most of the clustering sensitivity to sound speed variations arises from $z \\lsim 1.5$. A detection of models with sound speeds close to zero, $c_s \\lsim 0.01,$ is possible for dark energy models with $w\\gsim -0.9$.

Propagation of sound waves through a spatially homogeneous but smoothly time-dependent medium  

SciTech Connect (OSTI)

The propagation of sound through a spatially homogeneous but non-stationary medium is investigated within the framework of fluid dynamics. For a non-vortical fluid, especially, a generalized wave equation is derived for the (scalar) potential of the fluid velocity distribution in dependence of the equilibrium mass density of the fluid and the sound wave velocity. A solution of this equation for a finite transition period ? is determined in terms of the hypergeometric function for a phenomenologically realistic, sigmoidal change of the mass density and sound wave velocity. Using this solution, it is shown that the energy flux of the sound wave is not conserved but increases always for the propagation through a non-stationary medium, independent of whether the equilibrium mass density is increased or decreased. It is found, moreover, that this amplification of the transmitted wave arises from an energy exchange with the medium and that its flux is equal to the (total) flux of the incident and the reflected wave. An interpretation of the reflected wave as a propagation of sound backward in time is given in close analogy to Feynman and Stueckelberg for the propagation of anti-particles. The reflection and transmission coefficients of sound propagating through a non-stationary medium is analyzed in more detail for hypersonic waves with transition periods ? between 15 and 200 ps as well as the transformation of infrasound waves in non-stationary oceans. -- Highlights: Analytically exact study of sound propagation through a non-stationary medium. Energy exchange between the non-stationary medium and the sound wave. Transformation of hypersonic and ultrasound frequencies in non-stationary media. Propagation of sound backward in time in close analogy to anti-particles. Prediction of tsunamis both in spatially and temporally inhomogeneous oceans.

Propagation of Transient Sound Signals into a Viscous Fluid  

Science Journals Connector (OSTI)

An arbitrary excitation of the plane x = 0 sends sound signals into the half?space x ? 0 occupied by the viscous fluid. The governing third?order partial differential equation is solved exactly using the Laplace transform on time and the sine transform on space. New expressions for the most general solution are derived. The specific inputs considered in detail are the Dirac delta function the Heaviside unit function a decaying exponential and a sinusoidal excitation. The final expressions are given in the form of real integrals and of exact power series. Short?time approximations are also given for a general input and for the four aforementioned specific inputs. Previously obtained approximations for the case of small attenuation coefficients are corrected and extended for the decaying exponential and the sinusoidal input. The results found indicate that viscosity tends to reduce the sharpness of the propagating disturbance and thus to smooth out any initially imposed discontinuity. The presence of the disturbance is felt immediately everywhere in the medium and in fact the short?time approximations satisfy the parabolic heat equation.

Processing of Prosthetic Heart Valve Sounds from Anechoic Tank Measurements  

SciTech Connect (OSTI)

People with serious cardiac problems have had their life span extended with the development of the prosthetic heart valve. However, the valves operate continuously at approximately 39 million cycles per year and are therefore subject to structural failures either by faulty design or material fatigue. The development of a non-invasive technique using an acoustic contact microphone and sophisticated signal processing techniques has been proposed and demonstrated on limited data sets. In this paper we discuss an extension of the techniques to perform the heart valve tests in an anechoic like. Here the objective is to extract a ''pure'' sound or equivalently the acoustical vibration response of the prosthetic valves in a quiet environment. The goal is to demonstrate that there clearly exist differences between values which have a specific mechanical defect known as single leg separation (SLS) and non-defective valves known as intact (INT). We discuss the signal processing and results of anechoic acoustic measurements on 50 prosthetic valves in the tank. Finally, we show the results of the individual runs for each valve, point out any of the meaningful features that could be used to distinguish the SLS from INT and summarize the experiments.

Measurement of sound transmission through mud at Dodge Pond, Connecticut  

Science Journals Connector (OSTI)

Depositional muddy sediments are slow bottoms and pose a problem for the sonic detection of buried ordnance. This paper addresses the question: can the frequency dependent dispersion be predicted and verified by measurements in areas where buried object detection is required? Wood and Weston (Acustica V14 1964) have indicated that muddy sediments in the kHz range have a compressional speed 3% less than water with a frequency dependent attenuation (less than that of sand). A theoretical treatment of "muddy sediments" the Card House Theory (Pierce and Carey POMA (5) 7001 2009) estimates the slow sound speed and frequency dispersion proportional to mud porosity. Preliminary Dodge Pond results obtained with a buried array (1 to 10 kHz) are presented and illustrate the importance of micro-bubbles on the dispersion characteristic. The initial measurements on the disturbed sediment were found strongly influenced by scattering from larger bubbles whereas the results after a period of 10 months showed the effect of a smaller size distribution of bubbles. Estimates of the dispersion characteristic of mud and the effect of micro-bubbles are discussed. Finally the application of an impedance tube to the characterization of mud is discussed.

Sound propagation over Dickins Seamount in the Northeast Pacific Ocean  

Science Journals Connector (OSTI)

The acoustic propagation losses between a 230?Hz cw source and a multi?hydrophone receiving system were measured over Dickins Seamount in the Northeast Pacific. The source was towed at depths of 18 and 184 m. The receiving system had hydrophones spaced in depth from 323 to 633 m. The measurements were made to a maximum range of 130 km with the receiver located at a range of 60 km from the seamount peak. The results show that the seamount cast an acoustic shadow over the receiver increasing the propagation loss by up to 15 dB when the source was shallow and in a position which enabled the seamount to intercept all of the deep refracted source energy. Back reflections from the seamount with levels 6 to 13 dB below the direct signal level were present when the shallow source was 3 to 5 km from the seamount peak. Downslope reflections enhanced the direct signal by up to 10 dB when the shallow source was within 3 km of the peak. Acoustic shadowing and reflection effects were minimal in the results for the deep source because most of the source energy propagated along the sound?channel axis above the seamount peak. The analysis indicates that ray theory is adequate for describing the reflection effects of the acoustic propagation but does not account for all of the acoustic energy in the shadow zone.

The Velocity of Sound in an Absorptive Gas  

Science Journals Connector (OSTI)

The theory of velocity propagation in a gas as conditioned by internal energy exchanges is considered in detail for the simplest case in which the "lags" may be differentnamely, the model with three sets of states. This "second order" theory is required for the interpretation of experimental results where the wave period is of the order of the lag for some states. Assuming the first vibration state of CO2 to have the largest lag in accordance with Kneser's interpretation of his recent experiments, the necessary approximations are given explicitly and the results are directly applicable to CO2. The apparent lag as measured in sound velocity experiments is not the simple stationary state mean "collision life" nor the mean life of the energy quantum except under special conditions and then for only one of the states. The velocity increment in the "resonance" region is given more accurately in terms of transition probabilities and is not described completely by the specific heats as might be expected from the "first order" theory. Contrary to the indications of the simple theory with an empirical constant the external energy is always merely the translation term. The status of the assumed lag assignment in CO2 is discussed in the light of the results and underlying theory of this paper.

Instrumentation for Studies of Sound in the Atmosphere  

Science Journals Connector (OSTI)

Explosive charges are fired on the earth's surface at points in Arizona California and San Clemente Island. The resulting sound waves centering at 2 cps are detected by an array of sensing units in Southwestern Arizona. This array extends 108 miles along an east?west segment of a great circle with units placed at 4?mile intervals. From these units transmission lines are routed along the ground to recording stations near Dateland and Gila Bend. A single twin?conductor field line serves from one to three units and may be as long as 40 miles. Over such a line the sensing units are turned on by relays and the signals are transmitted to the recording station. The use of carriers has permitted the separation of multiplexed signals by means of tuning controls. Push?pull condenser?coupled amplifiers drive the Brush recording pens. Sensitivity is controlled in 6?db steps through a range from 5 to 160 dynes per sq cm peak?to?peak for full scale deflection. A pass band from 0.2 to 5 cps is set by an acoustic filter in the sensing unit. Several years of use and development have resulted in a system which has proved to be quite satisfactory.

HEARING AND LATERAL LINE | Effects of Human-Generated Sound on Fish  

Science Journals Connector (OSTI)

Abstract Fish depend on sound to communicate with one another, detect prey and predators, navigate from one place to another, avoid hazards, and analyze the world around them. The generation of noise in the ocean, lakes, and rivers by shipping, construction activities, seismic surveys, and sonar systems may affect fish adversely. In recent years, there has been a significant increase in the levels and incidence of human-generated underwater sound, and much of the technology contributing to ocean noise is new. Efforts are now underway to regulate activities that generate underwater sound with the aim of reducing noise levels and minimizing effects upon fish and other aquatic animals.

Health-risk assessment of chemical contamination in Puget Sound seafood. Final report 1985-1988  

SciTech Connect (OSTI)

This report provides resource management and health agencies with a general indication of the magnitude of potential human health risks associated with consumption of recreationally harvested seafoods from Puget Sound. Data collection and evaluation focused on a variety of metal and organic contaminants in fish, shellfish and edible seaweeds from 22 locations in the Sound. EPA risk assessment techniques were used to characterize risks to average and high consumer groups for both carcinogens and noncarcinogens. Theoretical risks associated with consumption of both average and high quantities of Puget Sound seafood appear to be comparable to or substantially less than those for fish and shellfish from other locations in the United States.

Possibility of Sound Propagation in Vacuums with the Speed of Light  

E-Print Network [OSTI]

An important question of theoretical physics is whether sound is able to propagate in vacuums at all and if this is the case, then it must lead to the reinterpretation of one zero-restmass particle which corresponds to vacuum-sound waves. Taking the electron-neutrino as the corresponding particle, its observed non-vanishing rest-energy may only appear for neutrino-propagation inside material media. The idea may also influence the physics of dense matter, restricting the maximum speed of sound, both in vacuums and in matter to the speed of light.

Study of the Acoustic Effects of Hydrokinetic Tidal Turbines in Admiralty Inlet, Puget Sound  

SciTech Connect (OSTI)

Hydrokinetic turbines will be a source of noise in the marine environment - both during operation and during installation/removal. High intensity sound can cause injury or behavioral changes in marine mammals and may also affect fish and invertebrates. These noise effects are, however, highly dependent on the individual marine animals; the intensity, frequency, and duration of the sound; and context in which the sound is received. In other words, production of sound is a necessary, but not sufficient, condition for an environmental impact. At a workshop on the environmental effects of tidal energy development, experts identified sound produced by turbines as an area of potentially significant impact, but also high uncertainty. The overall objectives of this project are to improve our understanding of the potential acoustic effects of tidal turbines by: (1) Characterizing sources of existing underwater noise; (2) Assessing the effectiveness of monitoring technologies to characterize underwater noise and marine mammal responsiveness to noise; (3) Evaluating the sound profile of an operating tidal turbine; and (4) Studying the effect of turbine sound on surrogate species in a laboratory environment. This study focuses on a specific case study for tidal energy development in Admiralty Inlet, Puget Sound, Washington (USA), but the methodologies and results are applicable to other turbine technologies and geographic locations. The project succeeded in achieving the above objectives and, in doing so, substantially contributed to the body of knowledge around the acoustic effects of tidal energy development in several ways: (1) Through collection of data from Admiralty Inlet, established the sources of sound generated by strong currents (mobilizations of sediment and gravel) and determined that low-frequency sound recorded during periods of strong currents is non-propagating pseudo-sound. This helped to advance the debate within the marine and hydrokinetics acoustic community as to whether strong currents produce propagating sound. (2) Analyzed data collected from a tidal turbine operating at the European Marine Energy Center to develop a profile of turbine sound and developed a framework to evaluate the acoustic effects of deploying similar devices in other locations. This framework has been applied to Public Utility District No. 1 of Snohomish Country's demonstration project in Admiralty Inlet to inform postinstallation acoustic and marine mammal monitoring plans. (3) Demonstrated passive acoustic techniques to characterize the ambient noise environment at tidal energy sites (fixed, long-term observations recommended) and characterize the sound from anthropogenic sources (drifting, short-term observations recommended). (4) Demonstrated the utility and limitations of instrumentation, including bottom mounted instrumentation packages, infrared cameras, and vessel monitoring systems. In doing so, also demonstrated how this type of comprehensive information is needed to interpret observations from each instrument (e.g., hydrophone data can be combined with vessel tracking data to evaluate the contribution of vessel sound to ambient noise). (5) Conducted a study that suggests harbor porpoise in Admiralty Inlet may be habituated to high levels of ambient noise due to omnipresent vessel traffic. The inability to detect behavioral changes associated with a high intensity source of opportunity (passenger ferry) has informed the approach for post-installation marine mammal monitoring. (6) Conducted laboratory exposure experiments of juvenile Chinook salmon and showed that exposure to a worse than worst case acoustic dose of turbine sound does not result in changes to hearing thresholds or biologically significant tissue damage. Collectively, this means that Chinook salmon may be at a relatively low risk of injury from sound produced by tidal turbines located in or near their migration path. In achieving these accomplishments, the project has significantly advanced the District's goals of developing a demonstration-scale tidal energy proj

Radio sounding in space: magnetosphere and topside ionosphere  

Science Journals Connector (OSTI)

Modern sounding techniques have been developed for the space-borne exploration of Earth's magnetosphere and topside ionosphere. Two new satellite instruments will use the advanced techniques of the ground-based Digisondes. The Radio Plasma Imager (RPI), a low-frequency sounder with 500-m dipole antennas designed to sweep from 3 kHz to 3 MHz, will be part of NASA's IMAGE mission to be launched in February 2000 into an elliptical orbit with an altitude at apogee of 7Re. While in the magnetospheric cavity, RPI will receive echoes from the magnetopause and the plasmasphere and will measure the direct response of the magnetosphere's configuration to changes in the solar wind. With three orthogonal dipole antennas (two 500-m tip-to-tip antennas in the spin plane used for transmission and reception, one 20-m antenna along the spin axis for reception only) the arrival angle of returning echoes can be determined with high accuracy. The other instrument is the \\{TOPside\\} Automated Sounder (TOPAS), which was originally conceived for the Ukrainian WARNING mission with a launch date in 2001. Using one antenna for transmission and three orthogonal 10-m antennas for reception, TOPAS will be able to determine the arrival angle of ionospheric echoes and their wave polarization. It will then be possible to automatically scale the topside ionograms and calculate the electron density profiles in real time. Operating as a high-frequency radar, TOPAS will for the first time measure topside plasma velocities by tracking the motions of plasma irregularities.

Inter?laboratory variation in sound power levels in qualified reverberant rooms.  

Science Journals Connector (OSTI)

Reverberant acoustic test facilities can be qualified to determine the sound power levels of broadband and tonal noise sources using the procedures defined in Air?Conditioning Heating and Refrigeration Institute (AHRI) Std. 220 Sound Power Testing Using Reverberant Rooms for HVAC Equipment. Member companies from AHRIs Technical Committee on Sound participated in a round robin test program in which tonal noise sources were shipped to and tested in a number of qualified reverberant rooms. This report summarizes the results of this effort. The mean and standard deviations of the sound power levels for multiple locations/orientations of the noise sources in each facility and for all facilities are presented. The standard deviations as a function of frequency for these sources were found to be generally less than the values established for broadband sources and therefore less than those allowed for tonal sources.

Untangling the roles of wind, run-off and tides in Prince William Sound  

Science Journals Connector (OSTI)

Prince William Sound (PWS) oceanic circulation is driven by a combination of local wind, large run-off and strong tides. Using a regional oceanic model of the Gulf of Alaska, adequately resolving the mean circulation and mesoscale eddies, we configure a series of three nested domains. The inner domain zooms in on Prince William Sound with a 1-km horizontal grid resolution. We analyze a set of four experiments with different combinations of run-off, wind and tides to demonstrate the relative influence of these forcing on the central Sound mean circulation cell and its seasonal variability. The mean circulation in the central PWS region is generally characterized by a cyclonic cell. When forced only by the wind, the circulation is cyclonic in winter and fall and strongly anticyclonic in summer. The addition of freshwater run-off greatly enhances the eddy kinetic energy in PWS partly through near-surface baroclinic instabilities. This leads to a much more intermittent circulation in the central Sound, with the presence of intense small-scale turbulence and a disappearance of the summer wind-forced anticyclonic cell. The addition of tides reduces the turbulence intensity (relatively to the experiment with run-off only), particularly in the central Sound. The generation of turbulent motions by baroclinic processes is lowered by tidal mixing and by modification of the exchange at Hinchinbrook Entrance. Tides have an overall stabilizing effect on the central Sound circulation. Tidal rectification currents help maintain a mean cyclonic circulation throughout the year.

Science Journals Connector (OSTI)

AlSi closed-cell aluminum foam sandwich panels (1240mmנ1100mm) of different thicknesses and different densities were prepared by molten body transitional foaming process in Northeastern University. The experiments were carried out to investigate the sound insulation property of AlSi closed-cell aluminum foam sandwich panels of different thicknesses and different densities under different frequencies (1004000Hz). Results show that sound reduction index (R) is small under low frequencies, large under high frequencies; thickness affects the sound insulation property of material obviously: when the thicknesses of AlSi closed-cell aluminum foam sandwich panels are 12, 22, and 32mm, the corresponding weighted sound reduction indices (RW) are 26.3, 32.2, and 34.6dB, respectively, the rising trend tempered; the increase of density of AlSi closed-cell aluminum foam can also increase the sound insulation property: when the densities of aluminum foam are 0.31, 0.51, and 0.67g/cm3, the corresponding weighted sound reduction indices (RW) are 28.9, 34.3, and 34.6dB, the increasing value mitigating.

The modeling and calculation of sound radiation from facilities with gas flowed pipes  

Science Journals Connector (OSTI)

Computer modeling of industrial facilities like chemical plants refineries or other production areas is the first and most important step in the calculation of sound exposure in the environment. The pipework with gas flows is often contributing relevant to the sound radiation of the complete facility. This radiation can be determined applying the methods described in technical papers like VDI 3733 and ISO 15664. On the basis of these descriptions a software tool was developed that allows to create pipework in 3D models with line sources and to calculate the sound propagation with methods like ISO 9613-2. The line sources are linked with the technical parameters like pipe cross section flow rate pressure density and temperature of the gas and material parameters of the pipe wall. The sound power emission from the pipe to the environment and the internal flow of sound powerlinked to the next section of pipingis calculated on the basis of these parameters. The same technique is used to calculate the sound emission of cooling towers electric and fuel driven motors gears pumps and other devices. This powerful technique allows creating sustainable models that can be adapted to different operation conditions with minimum time and effort.

Reaction of plaice (Pleuronectes platessa) and cod (Gadus morhua) to low?frequency sound in an experimental tank  

Science Journals Connector (OSTI)

Anthropogenic sound in the sea is an increasing problem and more knowledge on the influence of sound on fish needs to be collected. For this reason experiments are carried out in an experimental tank 10 m in diameter to examine the reaction of juvenile and adult cod and plaice to sound. Pure tones from the frequency range of offshore wind turbines are artificially emitted in typical wind turbinesound levels of 130 and 140 dB re 1 Pa. A sound gradient in the tank enables the fish to avoid highest sound levels. The number of fish in the vicinity of the sound source is determined in regular time intervals before during and after the 24?h period of sound exposure. Changes in numbers of fish can be seen in the periods with and without sound in many experiments. Reactions of plaice are ambiguous pointing to both avoidance of or attraction to the sound. In the majority of the experiments carried out on cod avoidance behavior to the sound can be seen with strongest reactions at 25 60 and 90 Hz. The results indicate potential avoidance behavior of cod to the operational noise of offshore wind farms.

Classification of heart valve sounds from experiments in an anechoic water tank  

SciTech Connect (OSTI)

In vivo studies in both sheep and humans were plagued by a number of problems including movement artifacts, biological noise, low signal-to-noise ratio (SNR), chest-wall reverberation, and limited bandwidth recordings as discussed by [1]. To overcome these problems it was decided to record heart valve sounds under controlled conditions deep in an anechoic water tank, free from reverberation noise. The main goal of this experiment was to obtain measurements of ''pure'' heart valve sounds free of the scattering effects of the body. Experiments were conducted at the Transdec facility in San Diego [2]. We used a high quality hydrophone together with a wide-band data acquisition system [2]. We recorded sounds from 100 repetitions of the opening-closing cycles on each of 50 different heart valves, including 21 SLS valves and 29 intact valves. The power spectrum of the opening and closing phases of each cycle were calculated and outlier spectra removed as described by Candy [2]. In this report, we discuss the results of our classification of the heart valve sound measurements. The goal of this classification task was to apply the fundamental classification algorithms developed for the clinical data in 1994 and 1996 to the measurements from the anechoic water tank. From the beginning of this project, LLNL's responsibility has been to process and classify the heart valve sounds. For this experiment, however, we processed both the opening sounds and closing sounds for comparison purposes. The results of this experiment show that the classifier did not perform well because of low signal-to-noise ratio and excessive variability in signal power from beat-to-beat for a given valve.

Puget Sound Dissolved Oxygen Modeling Study: Development of an Intermediate Scale Water Quality Model  

SciTech Connect (OSTI)

The Salish Sea, including Puget Sound, is a large estuarine system bounded by over seven thousand miles of complex shorelines, consists of several subbasins and many large inlets with distinct properties of their own. Pacific Ocean water enters Puget Sound through the Strait of Juan de Fuca at depth over the Admiralty Inlet sill. Ocean water mixed with freshwater discharges from runoff, rivers, and wastewater outfalls exits Puget Sound through the brackish surface outflow layer. Nutrient pollution is considered one of the largest threats to Puget Sound. There is considerable interest in understanding the effect of nutrient loads on the water quality and ecological health of Puget Sound in particular and the Salish Sea as a whole. The Washington State Department of Ecology (Ecology) contracted with Pacific Northwest National Laboratory (PNNL) to develop a coupled hydrodynamic and water quality model. The water quality model simulates algae growth, dissolved oxygen, (DO) and nutrient dynamics in Puget Sound to inform potential Puget Sound-wide nutrient management strategies. Specifically, the project is expected to help determine 1) if current and potential future nitrogen loadings from point and non-point sources are significantly impairing water quality at a large scale and 2) what level of nutrient reductions are necessary to reduce or control human impacts to DO levels in the sensitive areas. The project did not include any additional data collection but instead relied on currently available information. This report describes model development effort conducted during the period 2009 to 2012 under a U.S. Environmental Protection Agency (EPA) cooperative agreement with PNNL, Ecology, and the University of Washington awarded under the National Estuary Program

Recording and Calculating Gunshot SoundChange of the Volume in Reference to the Distance  

Science Journals Connector (OSTI)

An experiment was conducted in an open practice ground (shooting range) regarding the recording of the sound of gunshots. Shots were fired using various types of firearms (seven pistols five revolvers two submachine guns one rifle and one shotgun) in different calibers from several various distances with reference to the recording sources. Both a conventional sound level meter (device) and a measurement microphone were used having been placed in a fixed point behind the shooting line. The sound of each shot was recorded (from the device). At the same time the signal received by the microphone was transferred to a connected computer through an appropriate audio interface with a pre?amplifier. Each sound wave was stored and depicted as a wave function. After the physic?mathematical analysis of these depictions the volume was calculated in the accepted engineering units(Decibels or dB) of Sound Pressure Level (SPL). The distances from the recording sources were 9.60 meters 14.40 m 19.20 m and 38.40 m. The experiment was carried out by using the following calibers: .22 LR 6.35 mm(.25 AUTO) 7.62 mm Tokarev (7 6225) 7.65 mm(.32 AUTO) 9 mm Parabellum (919) 9 mm Short (917) 9 mm Makarov (918) .45 AUTO .32 S&W .38 S&W .38 SPECIAL .357 Magnum 7 62 mm Kalashnikov (7 6239) and 12 GA. Tables are given for the environmental conditions (temperature humidity altitude & barometric pressure) the length of the barrel of each gun technical characteristics of the used ammunition as well as for the volume taken from the SLM. The data for the sound intensity were collected after 168 gunshots (158 single shot & 10 bursts). According to the results a decreasing of the volume equivalent to the increasing of the distance was remarked as it was expected. Values seem to follow the Inverse square Law. For every doubling of the distance from the sound source the sound intensity diminishes by 5.99040.2325 decibels (on average). In addition we have the chance of determining the volume of the gunshot sound coming from a certain type of weapon. A further application could be the calculation of the distance from a shooting firearm if one is aware of a recorded volume.

Uncertainty of sound power levels determined following Air Conditioning Heating and Refrigeration Institute Standard 220  

Science Journals Connector (OSTI)

As part of the AHRI ASA-ANSI and ISO standards development processes the uncertainty of sound power measurements needs to be quantified for inclusion in sound power standards. A study of four reverberation rooms with volumes of 140 280 560 and 1790 cubic meters was undertaken. Sound power levels for five noise sources (two vertical shafted sound sources two horizontal shafted sound sources and a leaf blower) were determined using ARI Standard 220. Variables investigated include: source location source orientation room conditions source operating characteristics and microphone traverse length. The frequency range of interest was 25 Hz to 10 kHz. Measurements were repeated and the order of tests was randomized. Of particular interest was the difference between the 140 cubic foot room and the other rooms to confirm the room qualification process required by ARI Standard 220 because the 140 cubic foot room does not meet the ARI Standard 220 qualification process but does meet the requirements in ISO 3741. This work will be helpful in understanding the sources of variation and allow for a starting point for determining if improvements are needed and if so what factors should be considered.

Artificial neural networks for breathing and snoring episode detection in sleep sounds  

Science Journals Connector (OSTI)

Obstructive sleep apnea (OSA) is a serious disorder characterized by intermittent events of upper airway collapse during sleep. Snoring is the most common nocturnal symptom of OSA. Almost all OSA patients snore, but not all snorers have the disease. Recently, researchers have attempted to develop automated snore analysis technology for the purpose of OSA diagnosis. These technologies commonly require, as the first step, the automated identification of snore/breathing episodes (SBE) in sleep sound recordings. Snore intensity may occupy a wide dynamic range (>95dB) spanning from the barely audible to loud sounds. Low-intensity SBE sounds are sometimes seen buried within the background noise floor, even in high-fidelity sound recordings made within a sleep laboratory. The complexity of SBE sounds makes it a challenging task to develop automated snore segmentation algorithms, especially in the presence of background noise. In this paper, we propose a fundamentally novel approach based on artificial neural network (ANN) technology to detect SBEs. Working on clinical data, we show that the proposed method can detect SBE at a sensitivity and specificity exceeding 0.892 and 0.874 respectively, even when the signal is completely buried in background noise (SNR

Effects of attenuation, dispersion, and high sound?pressure levels on acoustic wave distortion in horns  

Science Journals Connector (OSTI)

High?power sound sources have received a lot of attention in the past few years due to renewed interest in industrial applications of high?intensity sounds such as the acoustic agglomeration of aerosols or combustion enhancement. Most high?power sound sources require a horn to match the source impedance to the medium where the sound is radiated. Such horns introduce distortion in the initial waveform which can be detrimental to the agglomeration or combustion enhancement process. Boundary?layer attenuation smooths the wave shape while dispersion breaks up the symmetry of the waveform. Horn?induced dispersion is usually the dominant dispersion mechanism resulting in strong peaks in the waveform. Finally due to the very high acoustic levels at the horn throat finite?amplitude effects are responsible for a significant amount of distortion at high frequencies. Simple examples of waveform distortion due to these various mechanisms are shown. The effects of sound?pressure level horn design and frequency on distortion are illustrated for an exponential horn and several initial wave shapes. Experimental results are presented that compare very well with theory.

Anthropogenic soundIntroduction and overview of the ambient and anthropogenic environment  

Science Journals Connector (OSTI)

Interest in anthropogenic sound in the marine environment has been directed at concerns about the effects of sound on marine mammals. However fish make up a far larger and more diverse portion of the oceans than do marine mammals and they hold considerable economic importance internationally. This has led to a growing interest in the effect of anthropogenic sounds on fish in environments ranging from shallow waters near in?shore shipping lanes to the deep sea. Concerns for effects on fish are parallel to those for marine mammals and include issues ranging from the death of individual animals to the potential for behavioral changes that could lead to impacts on the survival of populations or species. While the body of data on the effects of anthropogenic sounds on fish is still small and much of the work is not in the peer?reviewed literature the number of peer?reviewed studies is growing. The purpose of this special session is to provide an overview of what we currently know about the effects of anthropogenic sound on fish help define the major outstanding questions on these effects and to provide the basis for discussion of current and future research in order to help resolve these questions.

Combining SRP-PHAT and two Kinects for 3D Sound Source Localization  

Science Journals Connector (OSTI)

Abstract The Kinect has been developed to recognize gestures and voice commands, through a set of cameras and microphones, respectively. This paper proposes and evaluates low-cost Sound Source Localization (SSL) solution based this off-the-shelf equipment. It consists of employing a pair of Kinect devices as an alternative for microphone array, and executing the Steered Response Power using the \\{PHAse\\} Transform (SRP-PHAT) localization algorithm over acquired sound data. A fully functional prototype has been implemented and put to test under a realistic scenario. Experimental results indicate that although our approach is capable of achieving limited position estimation, and it can accurately point towards the sources direction. Two different high performance versions of the algorithm have been implemented to improve overall system performance under 3D Sound Source Localization setup.

Ultrasonic Sound Field Mapping Through Coarse Grained Cast Austenitic Stainless Steel Components  

SciTech Connect (OSTI)

The Pacific Northwest National Laboratory (PNNL) has been involved with nondestructive examination (NDE) of coarse-grained cast austenitic stainless steel (CASS) components for over 30 years. More recent work has focused on mapping the ultrasonic sound fields generated by low-frequency phased array probes that are typically used for the evaluation of CASS materials for flaw detection and characterization. The casting process results in the formation of large grained material microstructures that are nonhomogeneous and anisotropic. The propagation of ultrasonic energy for examination of these materials results in scattering, partitioning and redirection of these sound fields. The work reported here provides an assessment of sound field formation in these materials and provides recommendations on ultrasonic inspection parameters for flaw detection in CASS components.

Dark energy with non-adiabatic sound speed: initial conditions and detectability  

SciTech Connect (OSTI)

Assuming that the universe contains a dark energy fluid with a constant linear equation of state and a constant sound speed, we study the prospects of detecting dark energy perturbations using CMB data from Planck, cross-correlated with galaxy distribution maps from a survey like LSST. We update previous estimates by carrying a full exploration of the mock data likelihood for key fiducial models. We find that it will only be possible to exclude values of the sound speed very close to zero, while Planck data alone is not powerful enough for achieving any detection, even with lensing extraction. We also discuss the issue of initial conditions for dark energy perturbations in the radiation and matter epochs, generalizing the usual adiabatic conditions to include the sound speed effect. However, for most purposes, the existence of attractor solutions renders the perturbation evolution nearly independent of these initial conditions.

A validated dynamic model of the first marine molten carbonate fuel cell  

Science Journals Connector (OSTI)

In this work we present a modular, dynamic and multi-dimensional model of a molten carbonate fuel cell (MCFC) onboard the offshore supply vessel Viking Lady serving as an auxiliary power unit. The model is able to capture detailed thermodynamic, heat transfer and electrochemical reaction phenomena within the fuel cell layers. The model has been calibrated and validated with measured performance data from a prototype installation onboard the vessel. The model is able to capture detailed thermodynamic, heat transfer and electrochemical reaction phenomena within the fuel cell layers. The model has been calibrated and validated with measured performance data from a prototype installation onboard the offshore supply vessel. The calibration process included parameter identification, sensitivity analysis to identify the critical model parameters, and iterative calibration of these to minimize the overall prediction error. The calibrated model has a low prediction error of 4% for the operating range of the cell, exhibiting at the same time a physically sound qualitative behavior in terms of thermodynamic heat transfer and electrochemical phenomena, both on steady-state and transient operation. The developed model is suitable for a wide range of studies covering the aspects of thermal efficiency, performance, operability, safety and endurance/degradation, which are necessary to introduce fuel cells in ships. The aim of this MCFC model is to aid to the introduction, design, concept approval and verification of environmentally friendly marine applications such as fuel cells, in a cost-effective, fast and safe manner.

Classification of heart valve sounds from experiments in an anechoic water tank  

SciTech Connect (OSTI)

In vivo studies in both sheep and humans were plagued by a number of problems including movement artifacts, biological noise, low signal-to-noise ratio (SNR), chest-wall reverberation, and limited bandwidth recordings as discussed by [1]. To overcome these problems it was decided to record heart valve sounds under controlled conditions deep in an anechoic water tank, free from reverberation noise, including surface reflections. Experiments were conducted in a deep water tank at the Transdec facility in San Diego, which satisfies these requirements. The Transdec measurements are free of reverberations, but not totally free of acoustic and electrical noise. We used a high quality hydrophone together with a wide-band data acquisition system [2]. We recorded sounds from 100 repetitions of the opening-closing cycles on each of 50 different heart valves, including 21 SLS valves and 29 intact valves. The power spectrum of the opening and closing phases of each cycle were calculated and outlier spectra removed as described by Candy [2]. In this report, we discuss the results of our classification of the heart valve sound measurements. The goal of this classification task was to apply the fundamental classification algorithms developed for the clinical data in 1994 and 1996 to the measurements from the anechoic water tank. From the beginning of this project, LLNL's responsibility has been to process and classify the heart valve opening sounds. For this experiment, however, we processed both the opening sounds and closing sounds for comparison purposes. The results of this experiment show that the classifier did not perform well. We believe this is because of low signal-to-noise ratio and excessive variability in signal power from beat-to-beat for a given valve.

Evaluation of hydro sound and vibration measurements during the use of the Hydro-Sound-Damper (HSD) at the wind farm London Array  

Science Journals Connector (OSTI)

Since some years a noise prevention concept for the protection of marine animals exists in Germany. Based on that the acoustic underwater noise from the pile driving at offshore wind farms is required to be less than 160 dB (SEL) at a distance of 750 m. This value however is often exceeded so that the use of a soundproofing system is necessary. The Hydro-Sound-Damper (HSD) is a new versatile method to reduce the noise during offshore pile driving. To achieve this elements of different sizes and materials are used which are fixed to fishing nets. The principle of operation and the effectiveness of these HSD elements were investigated in the laboratory and in situ under offshore conditions at the worlds largest offshore wind farm London Array. During the offshore tests thorough measurements were performed which metered the propagation of the hydro sound and the vibrations of the sea floor at various distances and directions. The evaluation of these data led to very promising results concerning underwater noise reduction. This article describes the theory and implementation of the HSD at London Array and focuses on the interpretation of the data from the hydro sound and vibration measurements.

Broadband low?frequency sound radiator with high?frequency pump resonator.  

Science Journals Connector (OSTI)

A new type of underwater low?frequency radiator is described. Operation of the radiator is based on the nonlinear conversion of high?frequency acoustic pump energy to low?frequency sound pulsation of the water volume of the open acoustic pump resonator. High?intensity pump waves in the resonator produce cavitation. Water containing bubbles is highly nonlinear (hundreds and even thousands of times more than pure water) and dispersive. Both of these factors and also the use of the pump resonator promote much stronger conversion of pump energy to low?frequency sound in comparison with a parametric radiator. The calculation of the acoustical characteristics is presented.

The application to permit a wind turbine power development usually involves submission of a prediction for the sound level that will occur at residences schools places of worship and elsewhere people gather for restorative rest. This paper uses the example of a wind power development and follows iterations taken to finalize the sound level prediction. The paper provides quantitative information collected since the start up of the wind power development on measured sound levels and octave band distribution; and qualitative observations on the special characteristics of the sound. Actual observations are compared to the predictions. More importantly the paper reviews the consequences self-reported in qualitative interviews by citizens living with the changed environment after four years of operation of the wind power development. Reported impacts included difficulty sleeping loss of jobs and changes to social relationships caregiving pursuit of hobbies leisure learning and overall health. Changes in measured health outcomes are identified. Both the quantitative and qualitative findings justify revision of the permitting process.

Passive acoustic monitoring of biological and anthropogenic sounds at Americas first offshore wind farm  

Science Journals Connector (OSTI)

Cape Wind situated in Nantucket Sound Massachusetts is poised to become Americas first offshore windfarm. Our objective is to establish baseline (pre-construction) sound levels of human and biological activity including diel and seasonal variability of various sound types at the construction site and three nearby comparison sites. Acoustic recorders have been deployed since April 2012 recording on a 10% duty cycle (sample rate: 80 kHz). Biological contributions to the local soundscape are primarily fish sounds with the dominant signal likely being cusk eel (Family Ophidiidae) calls. These calls which are composed of stereotyped pulses with an average bout duration of 3.3 0.8 s and mean peak frequency of 1030 200 Hz show both seasonal and diel variation. Dense choruses were detected during summer (July) but limited activity occurred in the fall and winter. During vocal periods detections occurred throughout the day but peaked near dusk. Vessel traffic also showed diel and seasonal trends with peaks during the daytime and in the summer which indicates that boat activity can be tracked acoustically. These trends in biological and anthropogenic activity provide key baseline records for evaluating the influence of windfarm construction and operation on a local US soundscape.

Compression of felt?type thermal insulation layer for underfloor heating system and floor impact sound  

Science Journals Connector (OSTI)

In Korea almost every house uses underfloor heating which has advantages of thermal comfort and energy efficiency. However when it is constructed for high?rise apartment houses it yields a problem in floor impact sound insulation. It accounts for the fact that a foam?type thermal insulator sandwiched between structural slab and heating floor functions as a spring and easily transmits impacts on the floor to the slab. In that case the system's transmissibility is determined by dynamic stiffness of the thermal insulation layer and the lower the dynamic stiffness is the more the floor impact is isolated. For that reason apartments construction companies are attempting to lower the dynamic stiffness of the thermal insulation layer for impact sound reduction. As part of the attempt felt?type materials with relatively low dynamic stiffness such as glass wool or polyester felt are considered as a substitution for the foam?type thermal insulator. However there is a possibility that compression of the felt?type materials would increase the dynamic stiffness and the impact sound insulation effect at early stage might be weakened in the long term. This paper investigates the correlation between gradual compression of the felt?type thermal insulation layer and the impact sound variation.

Behavioral reactions of cod and sole to playback of pile driving sound.  

Science Journals Connector (OSTI)

The effect of anthropogenic underwater sound on fish has become an important environmental issue. Pile?driving noise during construction is of particular concern as the very high sound pressure levels could potentially prevent fish from reaching breeding or spawning sites finding food and acoustically locating mates. This could result in long?term effects on reproduction and populationparameters. Additionally avoidance reactions might result in displacement away from potential fishing grounds and lead to reduced catches. However reaction thresholds and therefore the impacts of pile driving on the behavior of fish are completely unknown. Pile?driving noise was played back to cod and sole held in two large (40 m) net pens located in a quiet bay. Movements of the fish were analyzed using a novel acoustic tracking system. Received sound pressure level and particle motion were measured during the experiments. The results show significant movement responses to the pile?driving stimulus in both species at relatively low received sound pressure levels. This might indicate a rather large area of avoidance during real pile?driving operations. The results of the study have important implications on regulatory advice and the implementation of mitigation measures in the construction of offshore wind farms.

Acoustic conversion of heat to sound at mid?audio frequencies  

Science Journals Connector (OSTI)

A thermoacoustic prime mover was developed for conversion of heat to sound that is then directly converted to electricity. The acoustic device consists of a 2.7?kHz quarter?wave resonator with a stack of random material between a hot heat exchanger and a cold heat exchanger. It is loaded by a cavity that couples the sound to a piezoelectric device for generation of electrical power. Optimization of this device for energy conversion was based on studies of heat injection temperature difference threshold for onset of oscillation heat flow in the device quality factor Q of the resonator response time to heat input and sound power output. Parameters for optimization included different mesh sizes for the heat exchangers given stack filling factors and levels of positive feedback from the acoustic cavity. Response time to heat injection was lowered by coupling the heat source directly to the hot heat exchanger. Device efficiency was doubled by reducing heat losses along the supporting structure of the stack. Temperature differences for oscillation were as low as 50C and sound levels of 130 dB were achieved. Thus device performance was enhanced substantially by optimizing geometric factors.

Drilling and operational sounds from an oil production island in the ice-covered Beaufort Sea  

Science Journals Connector (OSTI)

Recordings of sounds underwater and in air and of iceborne vibrations were obtained at Northstar Island an artificial gravel island in the Beaufort Sea near Prudhoe Bay (Alaska). The aim was to document the levels characteristics and range dependence of sounds and vibrations produced by drilling and oil production during the winter when the island was surrounded by shore-fast ice. Drilling produced the highest underwater broadband (1010?000 Hz) levels (maximum=124 dB re: 1 ?Pa at 1 km) and mainly affected 7001400 Hz frequencies. In contrast drilling did not increase broadband levels in air or ice relative to levels during other island activities. Production did not increase broadband levels for any of the sensors. In all media broadband levels decreased by ?20 dB/tenfold change in distance. Background levels underwater were reached by 9.4 km during drilling and 34 km without. In the air and ice background levels were reached 510 km and 210 km from Northstar respectively depending on the wind but irrespective of drilling. A comparison of the recorded sounds with harbor and ringed seal audiograms showed that Northstar sounds were probably audible to seals at least intermittently out to ?1.5 km in water and ?5 km in air.

As part of a general study of underwater industrial noises and their effects on bowhead whales sounds from drilling and dredging operations were measured in the shallow waters (drilling drilling at a caisson?retained island transfer dredges and hopper dredges. Results are presented in spectrum graphs as sound pressure levels in third?octave and octave bands and as overall levels in the 20? to 1000?Hz band. Most energy from these sources was below 1000 Hz. The weakest drilling/dredging soundsmeasured came from a drillship performing logging operations (122125 dB r e:1 ?Pa 201000 Hz range 0.17 km). The strongest sounds came from a hopper dredge underway with a damaged propeller (150 dB range 0.46 km). Measured data were used to derive regression equations for received sound level versus range. In these shallow waters the overall noise (20? to 1000?Hz band) from most drilling and dredging operations would be at levels below the median ambient noise (99 dB) at ranges greater than 30 km.

Long?Range Sound?Propagation Study in the Southern OceanProject Neptune  

Science Journals Connector (OSTI)

An experiment to determine some characteristics of long?range underwater sound propagation was undertaken by the U.S. Naval Ordnance Laboratory in April 1964. In this experiment Project Neptune sound signals were dropped at various ranges from a listening station in Bermuda. To supplement this and other stations one was established by the New Zealand Naval Research Laboratory off southern New Zealand to record the sound signals dropped on the final phase between Cape Town South Africa and Perth Australia. The recorded energy was analyzed in 1 3 ?oct bands to determine the transmission?path characteristics for low frequencies. The signal envelopes were found to differ in shape from the usual solar case and the attenuations were much larger than previously obtained for either RSR (refracted?surface reflected) or sofar propagation. These differences may be explained in terms of the different velocity structure of the Southern Ocean from that sound in the Atlantic or Pacific Oceans. In particular the thermocline is not as pronounced as in temperate or tropical regions and is absent south of the Antarctic convergence. Thus the energy was transmitted by a mixture of RSR and sofar modes little sofar energy arriving from those shots whose tracks crossed the Antarctic convergence.

Visualization of the sound field generated by a plate?cavity coupled system using acoustic holography  

Science Journals Connector (OSTI)

In most cases of structural?acoustic problems it is reasonable to assume that structural vibration is not influenced by the surrounding fluid. In these cases the vibration of the structure is solved first then the radiation sound field is calculated by simply applying the KirchhoffHelmholtz integral equation. However this assumption is no longer satisfied when structural stiffness is small or fluid impedance is comparable to it. In this situation the vibration and acoustic fields are to be solved simultaneously. Although many researchers have studied this structural?acoustic coupling problem there are still difficulties in solving the problem analytically or even numerically. In this study visualization of sound field by a geometrically simple system (plate?cavity coupled system) is performed experimentally in order to figure out the coupling mechanism between fluid and structure. The system is excited by a speaker and both internal and external sound pressures are measured. The acoustic holographic method is used to estimate the sound field. The results exhibit that there are frequencies where both plate and cavity are strongly coupled as well as ones where the plate can be considered rigid. Visualization that shows acoustic power flow between the internal cavity and external field enables us to understand the fluid?structure coupling mechanism.

Ultrasonic Phased Array Sound Field Mapping Through Large-Bore Coarse Grained Cast Austenitic Stainless Steel (CASS) Piping Materials  

SciTech Connect (OSTI)

A sound field beam mapping exercise was conducted to further understand the effects of coarse grained microstructures found in CASS materials on phased array ultrasonic wave propagation. Laboratory measurements were made on three CASS specimens with different microstructures; the specimens were polished and etched to reveal measurable grain sizes, shapes and orientations. Three longitudinal, phased array probes were fixed on a specimen's outside diameter with the sound field directed toward one end (face) of the pipe segment over a fixed range of angles. A point receiver was raster scanned over the surface of the specimen face generating a sound field image.

Analyses were conducted between the resulting sound fields and the microstructural characteristics of each specimen.

Tidal Residual Eddies and their Effect on Water Exchange in Puget Sound  

SciTech Connect (OSTI)

Tidal residual eddies are one of the important hydrodynamic features in tidally dominant estuaries and coastal bays, and they could have significant effects on water exchange in a tidal system. This paper presents a modeling study of tides and tidal residual eddies in Puget Sound, a tidally dominant fjord-like estuary in the Pacific Northwest coast, using a three-dimensional finite-volume coastal ocean model. Mechanisms of vorticity generation and asymmetric distribution patterns around an island/headland were analyzed using the dynamic vorticity transfer approach and numerical experiments. Model results of Puget Sound show that a number of large twin tidal residual eddies exist in the Admiralty Inlet because of the presence of major headlands in the inlet. Simulated residual vorticities near the major headlands indicate that the clockwise tidal residual eddy (negative vorticity) is generally stronger than the anticlockwise eddy (positive vorticity) because of the effect of Coriolis force. The effect of tidal residual eddies on water exchange in Puget Sound and its sub-basins were evaluated by simulations of dye transport. It was found that the strong transverse variability of residual currents in the Admiralty Inlet results in a dominant seaward transport along the eastern shore and a dominant landward transport along the western shore of the Inlet. A similar transport pattern in Hood Canal is caused by the presence of tidal residual eddies near the entrance of the canal. Model results show that tidal residual currents in Whidbey Basin are small in comparison to other sub-basins. A large clockwise residual circulation is formed around Vashon Island near entrance of South Sound, which can potentially constrain the water exchange between the Central Basin and South Sound.

PV array simulator development and validation.  

SciTech Connect (OSTI)

The ability to harvest all available energy from a photovoltaic (PV) array is essential if new system developments are to meet levelized cost of energy targets and achieve grid parity with conventional centralized utility power. Therefore, exercising maximum power point tracking (MPPT) algorithms, dynamic irradiance condition operation and startup and shutdown routines and evaluating inverter performance with various PV module fill-factor characteristics must be performed with a repeatable, reliable PV source. Sandia National Laboratories is collaborating with Ametek Programmable Power to develop and demonstrate a multi-port TerraSAS PV array simulator. The simulator will replicate challenging PV module profiles, enabling the evaluation of inverter performance through analyses of the parameters listed above. Energy harvest algorithms have traditionally implemented methods that successfully utilize available energy. However, the quantification of energy capture has always been difficult to conduct, specifically when characterizing the inverter performance under non-reproducible dynamic irradiance conditions. Theoretical models of the MPPT algorithms can simulate capture effectiveness, but full validation requires a DC source with representative field effects. The DC source being developed by Ametek and validated by Sandia is a fully integrated system that can simulate an IV curve from the Solar Advisor Model (SAM) module data base. The PV simulator allows the user to change the fill factor by programming the maximum power point voltage and current parameters and the open circuit voltage and short circuit current. The integrated PV simulator can incorporate captured irradiance and module temperature data files for playback, and scripted profiles can be generated to validate new emerging hardware embedded with existing and evolving MPPT algorithms. Since the simulator has multiple independent outputs, it also has the flexibility to evaluate an inverter with multiple MPPT DC inputs. The flexibility of the PV simulator enables the validation of the inverter's capability to handle vastly different array configurations.

Verification and Validation of TMAP7  

SciTech Connect (OSTI)

The Tritium Migration Analysis Program, Version 7 (TMAP7) code is an update of TMAP4, an earlier version that was verified and validated in support of the International Thermonuclear Experimental Reactor (ITER) program and of the intermediate version TMAP2000. It has undergone several revisions. The current one includes radioactive decay, multiple trap capability, more realistic treatment of heteronuclear molecular formation at surfaces, processes that involve surface-only species, and a number of other improvements. Prior to code utilization, it needed to be verified and validated to ensure that the code is performing as it was intended and that its predictions are consistent with physical reality. To that end, the demonstration and comparison problems cited here show that the code results agree with analytical solutions for select problems where analytical solutions are straightforward or with results from other verified and validated codes, and that actual experimental results can be accurately replicated using reasonable models with this code. These results and their documentation in this report are necessary steps in the qualification of TMAP7 for its intended service.

Structures of resonators in a cavity for improving a sound insulation of a thin double-leaf panel  

Science Journals Connector (OSTI)

The specific acoustic problem of a double-leaf panel is a less sound insulation caused by a mass-air-mass resonance. For improving the sound insulation many studies have suggested Helmholtz resonators in the cavity which are tuned at the resonant frequency. They have measured and analyzed this problem of double-walls spaced with 100 mm thickness of air gap. They have suggested that the resonators improve the sound insulation to the resonant transmission and discussed its optimization for a gain by the resonators and structures set in the cavity. But it is unclear that those results can apply to sound insulation by a double grassing with 5 mm thickness of air gap which is often seen even as a thermal insulated window and whose air gap is quite thinner than that of the walls. Then this study measured effects of various resonators in the cavity for improving the sound insulation of thin double-leaf panels and discusses effects of structures and perforation ratio to the sound insulation. Moreover for analyzing the effects of resonators this study discusses measured results with theoretical studies of sound absorption models for resonators.

Validating the Melusine Gamma Spectroscopy Tool  

SciTech Connect (OSTI)

This technical report describes testing to evaluate the gamma spectroscopy tool, Melusine, under development by Pacific Northwest National Laboratory. The goal was to verify that the software can successfully be used to provide accurate results and statistical uncertainties for the detection of isotopes of interest and their activities. Of special interest were spectra similar to those produced by radionuclide stations that contribute to the Comprehensive Nuclear Test Ban Treaty Organizations International Monitoring System. Two data sets were used to test Melusines capabilities. The first was the result of a multi-lab calibration effort based on neutron activations produced at the University of California at Davis. The second was taken from the Proficiency Test Exercises conducted by the CTBTO directly in 2005. In 37 of 42 cases, Melusine produced results in agreement with the best answer presently available, in most cases with calculated uncertainties comparable to or better than competing analyses. In fact, Melusine technically provided one more result than CTBTOs PTE analyses that agreed with the book answer (Monte Carlo simulation). Despite these promising results, the Melusine software is still under development. Effort is especially needed to simplify its analysis process, improve stability, and provide user documentation. Some significant analysis tasks require further vetting, such as those to address summing effects. However, our test results indicate that Melusines calculations as presently implemented are sound and can be used to reliably analyze spectra from the CTBTOs radionuclide stations.

Rapid deterioration of sound level benefits for quieter pavements in Washington state based on the on?board sound intensity method.  

Science Journals Connector (OSTI)

This paper provides detailed descriptions of the three test sections of quieter pavement evaluated by the Washington State Department of Transportation (WSDOT) using the on?board sound intensity (OBSI) method and the unique deterioration of those pavements. Within 6 months of installation OBSI for the test sections were not audibly lower than the control sections. OBSI is the predominant metric used to evaluate the success of quieter pavements in Washington State. Monthly OBSI measurements describe the seasonal variability in measuredsound levels and highlight more rapid general sound level increases in the test pavements relative to the control. Asphalt mix compositions and installation procedures used in Washington were similar or identical to those used in southern states where the same pavements have been successful. Challenges to the success of all pavements in Washington State include studded tires frequent freeze?thaw cycles and cool summers that encourage lower surface temperatures during installation than in southern states. These challenges are particularly significant for open?graded friction course OGFC pavements as evidenced by spikes in OBSI measurements following seasonal weather events. Parallels between OBSI measurements and structural durability measurements are described in detail.

Difference between zero- and first-sound propagation in solid Kr  

Science Journals Connector (OSTI)

We point out that the zero-sound-first-sound difference in solid rare gases is a very sensitive probe of the phonon self-energy. Recent advances in our knowledge of the interatomic potentials of these solids have enabled us to remove much of the ambiguity from this source and hence focus directly on the influence of different model self-energies. We have investigated the approximations of Koehler and Goldman, Horton, and Klein using a self-consistent harmonic basis with no explicit inclusion of hard-core effects. We find that the previously unexplained experimental result for solid Kr near melting, that C44 as measured by neutron scattering is 12% greater than obtained from Brillouim scattering, lies between the predictions of these two approximations.

Attenuation of low?frequency sound in the Northeast Pacific Ocean  

Science Journals Connector (OSTI)

Long?range propagation losses were measured at frequencies from 0.025 to 0.8 kHz to the north and south of a receiver at 46?N 14330?W in the Northeast Pacific. To the south of the station the attenuation losses experienced a pronounced minimum near 50 Hz and approached the one?half Thorp value at 0.8 kHz. An examination of the behavior of the attenuation coefficient as a function of range indicated that a range of at least 700 km would be required to make meaningful measurements of attenuation in this area. To the north of the receiving station focusing of the sound due to a rapidly shallowing sound channel prevented reliable measurement of the attenuation coefficient at any range.

In the present work, we analyze the corrections caused by an anomalous dispersion relation, suggested in several quantum gravity models, upon the speed of sound in a weakly interacting Bose--Einstein Condensate, trapped in a potential of the form $V(r)\\sim r^{2}$. We show that the corresponding ground state energy and consequently, the associated speed of sound, present corrections respect to the usual case, which may be used to explore the sensitivity to Planck--scale effects on these relevant properties associated with the condensate. Indeed, we stress that this type of macroscopic bodies may be more sensitive, under certain conditions, to Planck--scale manifestations than its constituents. In addition, we prove that the inclusion of a trapping potential, together with many--body contributions, improves the sensitivity to Planck--scale signals, compared to the homogeneous system.

Microscopic theory of sound propagation in the superfluid {sup 3}He-aerogel system  

SciTech Connect (OSTI)

We present a theory of sound propagation in superfluid {sup 3}He confined in aerogel, taking dragged aerogel motion into account. The superfluid dynamics coupled with the aerogel motion is formulated by use of the Keldysh Green's function for weak-coupling superfluid Fermi liquid. We apply the theory to the hydrodynamic regime and calculate the attenuation of a hydrodynamic longitudinal sound mode, the so-called fast mode. The result is compared to the acoustic experiment reported by the Northwestern University group [R. Nomura, G. Gervais, T. M. Haard, Y. Lee, N. Mulders, and W. P. Halperin, Phys. Rev. Lett. 85, 4325 (2000); G. Gervais, R. Nomura, T. M. Haard, Y. Lee, N. Mulders, and W. P. Halperin, J. Low Temp. Phys. 122, 1 (2001)]. We find reasonable agreement between the theory and the experiment.

For the application of new digital control and monitoring systems in nuclear power plants (NPPs), it is required to satisfy the proven technology requirements. They should have at least three years of documented, satisfactory service as modules of subsystems in power plant applications similar to that of NPP, or it should have three years of documented, satisfactory service in other plant applications which are similar to the use in NPP (EPRI-URD's first option). However, tlte digital control and monitoring systems developed by Korea Nuclear Instrumentation A Control System (KNICS) R and D Center, due to the nature of the firstly developed system, have had no prior application in any NPPs as well as industrial and fossil power plants. Therefore, well defined program using 'Integrated Performance Validation Facility (IPVF) 'for prototype testing has been prepared to verify their performance, operability and reliability according to EPRI-URD's second option: It has satisfactorily completed a defined program of prototype testing which has been designed to verify its performance. The IPVF for KNICS is being designed to justify that new control systems are proven to meet utility's requirements. The IPVF comprises Virtual Operating Crew (VOC) and Test Commander (TC).

We investigate heating of the cool core of a galaxy cluster through the dissipation of sound waves and weak shocks excited by the activities of the central active galactic nucleus (AGN). Using a weak shock theory, we show that this heating mechanism alone cannot reproduce observed temperature and density profiles of a cluster, because the dissipation length of the waves is much smaller than the size of the core and thus the wave energy is not distributed to the whole core.

GIVS: integrity validation for grid security  

Science Journals Connector (OSTI)

In recent years, grid computing has been recognised as the next step in the evolution of distributed systems. However, only limited efforts have been made to address the security issues involved in these architectures. Questions like 'What happens if a user of the grid is interested in making the overall computation fail?' are still unanswered. In this paper, we address the problem of granting the correctness of grid computations. We introduce a Grid Integrity Validation Scheme (GIVS) that may reveal the presence of malicious hosts through statistical sampling of computational results. Performance overheads of GIVS strategies are evaluated using statistical models and simulation.

The Equation of State of Water and Seawater as Determined from Sound Velocity Data  

Science Journals Connector (OSTI)

Using the high?pressure (0 to 1000 bars) sound?velocity measurements of Wilson (1960) an equation of state for PVT properties of water and seawater has been developed based on a modified Tait equation of the form V?V P VP = 1 B+A 1 P+A 2 P 2 in which V is the specific volume at atmospheric pressure VP the specific volume at pressureP and B A 1 and A 2 are functions of temperature and salinity. The equation has been fit with a maximum deviation in compressibility of 0.0110?6 bar?1 for seawater and 0.0210?6 bar?1 for pure water. The data from this equation will yield specific volumes that show the excellent consistency of Ekman's (1908) measurements with the sound data. The results for pure water show a definite shift in Kell and Whalley's (1965) measurements and the superiority of the PVT data generated from the sound data to direct experimental measurements.

Low frequency radiation from a (compact) structure with and without sound holes.  

Science Journals Connector (OSTI)

At long wavelengths a force driven closed elastic structure radiates as a dipole. However this may or may not be the case in the presence of a sound hole. Radiation remains dipole?like when the interior volume behaves as an acoustic fluid coupled to the structure. This is commonly referred to as the sound hole sum rule in musical acoustics [Weinreich (1985)]. However should the interior acoustic volume be uncoupled or simply ignored the radiated field is dominated by a monopole contribution. For example this may occur with mechanically isolated piping systems exposed to the exterior medium. In this situation the monopole or dipole nature of the radiation depends on the effective number of sound holes for example whether the driven system is well connected to the exterior along both the inlet and outlet. Finite element structural?acoustic models are developed and exercised to investigate these systems and issues. In addition a substructuring technique is utilized to account for the potential influences of interior structural complexity.

The low?frequency radiation and scattering of sound from bubbly mixtures near the sea surface  

Science Journals Connector (OSTI)

Microbubble plumes are produced when waves break and are convected to depth. What role these microbubble plumes have in the production of sound and the scattering of sound near the sea surface from the low? (20?Hz) to mid? (2?kHz) frequency range? Ocean ambient noise shows a dramatic increase in midfrequency levels when wave breaking occurs. Measurements of scattering from the sea surface have a different characteristic than expected by Bragg scattering from gravity waves i.e. a large zero Doppler component. If microbubbleclouds and plumes with void fractions greater than 0.0001 act as collective resonant oscillators then noise can be produced and scattering can occur with little Doppler shift but ample spread. This hypothesis was based on the theory that the mixture properties determine the radiation and scattering from such a compact region. Experimental results show that the far field radiation of sound from a compact region can be described by monopole volume pulsation beneath a pressure release surface with the natural frequency described by a modified Minneart formula. Scattering measurements from submerged bubble clouds show a significant low frequency scattering. Experimental evidence and theoretical formulations are consistent with collective phenomenon.

Quench dynamics in SRF cavities: can we locate the quench origin with 2nd sound?  

SciTech Connect (OSTI)

A newly developed method of locating quenches in SRF cavities by detecting second-sound waves has been gaining popularity in SRF laboratories. The technique is based on measurements of time delays between the quench as determined by the RF system and arrival of the second-sound wave to the multiple detectors placed around the cavity in superfluid helium. Unlike multi-channel temperature mapping, this approach requires only a few sensors and simple readout electronics; it can be used with SRF cavities of almost arbitrary shape. One of its drawbacks is that being an indirect method it requires one to solve an inverse problem to find the location of a quench. We tried to solve this inverse problem by using a parametric forward model. By analyzing the data we found that the approximation where the second-sound emitter is a near-singular source does not describe the physical system well enough. A time-dependent analysis of the quench process can help us to put forward a more adequate model. We present here our current algorithm to solve the inverse problem and discuss the experimental results.

On the stability of long-range sound propagation through a structured ocean  

E-Print Network [OSTI]

Several acoustic experiments show a surprising degree of stability in wave fronts propagating over multi-megameter ranges through the ocean's sound channel despite the presence of random-like, sound speed fluctuations. Previous works have pointed out the existence of chaos in simplified ray models incorporating structure inspired by the true ocean environment. A ``predictability horizon'' has been introduced beyond which stable wave fronts cease to exist and point-wise, detailed comparisons between even the most sophisticated models and experiment may be limited for fundamental reasons. We find, by applying one of the simplified models, that for finite ranges, the fluctuations of the ray stabilities are very broad and consistent with lognormal densities. A fraction of the rays retain a much more stable character than the typical ray. This may be one of several possible mechanisms leading to greater than anticipated sound field stability. The lognormal ray stability density may underlie the recent, experimentally determined, lognormal density of wave field intensities [J. Acoust. Soc. Am. 105 (1999) 3202--18].

Universal power spectra for acoustic turbulence: Applications to wind waves, 1/f noise, and classical second sound  

Science Journals Connector (OSTI)

A continuum pumped full of waveenergy at an amplitude sufficiently large so that reversible nonlinearities dominate irreversible linear response becomes waveturbulent. In the limit of high nonlinearity acoustic turbulence and wind waveturbulence accumulate at 1/f and 1/f 5 power spectra respectively. A waveturbulent system can support new propagating energy modes analogous to second sound in superfluid He4. This hyperbolic (nondiffusive) transport could account for the anomalous diffusivity observed in plasma devices and for the difficulties faced in achieving confinement. The key to the understanding of these phenomena is the nonlinearity in the continuum mechanics which leads to three basic effects: (1) scattering of sound by sound to produce waves with sum and difference frequencies; (2) refraction of waves by a slowly varying (inhomogeneous) background; (3) reaction of the background due to changes in the distribution of sound waves. Details of these processes are presented in the framework of the Euler equations.

CASL Validation Data: An Initial Review  

SciTech Connect (OSTI)

The study aims to establish a comprehensive view of data needed for supporting implementation of the Consortium of Advanced Simulation of LWRs (CASL). Insights from this review (and its continual refinement), together with other elements developed in CASL, should provide the foundation for developing the CASL Validation Data Plan (VDP). VDP is instrumental to the development and assessment of CASL simulation tools as predictive capability. Most importantly, to be useful for CASL, the VDP must be devised (and agreed upon by all participating stakeholders) with appropriate account for nature of nuclear engineering applications, the availability, types and quality of CASL-related data, and novelty of CASL goals and its approach to the selected challenge problems. The initial review (summarized on the January 2011 report version) discusses a broad range of methodological issues in data review and Validation Data Plan. Such a top-down emphasis in data review is both needed to see a big picture on CASL data and appropriate when the actual data are not available for detailed scrutiny. As the data become available later in 2011, a revision of data review (and regular update) should be performed. It is expected that the basic framework for review laid out in this report will help streamline the CASL data review in a way that most pertinent to CASL VDP.

Evaluating the bonding condition of NASA spray on foam insulation (SOFI) using audio frequency sound absorption measurements  

Science Journals Connector (OSTI)

The bonding condition of the spray on foam insulation (SOFI) used to insulate the external tank of the NASA space shuttle can be found by using the audio frequency sound absorption coefficient. The ASTM E1050 standard method for sound absorptionmeasurements was used with an open?ended 1?in?diam cast acrylic impedance tube sealed to the SOFI with closed cell PVC foam. Two artificially disbonded locations measuring 1.0 in. by 5.5 in. by 0.0625 in. and 2.0 in. by 8.0 in. by 0.0625 in. were detected by peaks in the sound absorption coefficient spectrum. The peaks in the sound absorptionspectrum between 1000 and 4000 Hz were 25% to 50% higher over disbonded areas when compared to bonded locations. The maximum and minimum sound absorption levels for the foam ranged between approximately 0.1 and 0.3. The entire sample was scanned using the sound absorption peaks as indicators. Samples of 2?in.?thick polystyrene foam were used with different sized defects at different locations in the foam to relate defect size and location to peaks in absorption coeffi?cient spectrum.

Structures of resonators in a cavity for improving a sound insulation of a thin double-leaf panel  

Science Journals Connector (OSTI)

The specific acoustic problem of a double-leaf panel is a less sound insulation caused by a mass-air-mass resonance. For improving the sound insulation many studies have suggested Helmholtz resonators in the cavity which are tuned at the resonant frequency. They have measured and analyzed this problem of double-walls spaced with 100 mm thickness of air gap. They have suggested that the resonators improve the sound insulation to the resonant transmission and discussed its optimization for a gain by the resonators and structures set in the cavity. But it is unclear that those results can apply to sound insulation by a double grassing with 5 mm thickness of air gap which is often seen even as a thermal insulated window and whose air gap is quite thinner than that of the walls. Then this study measured effects of various resonators in the cavity for improving the sound insulation of thin double-leaf panels and discusses effects of structures and perforation ratio to the sound insulation.

The MAX facility for CFD code validation  

SciTech Connect (OSTI)

ANL has recently completed construction of a fluid dynamics test facility devised to provide validation data for CFD simulation tools used to evaluate various aspects of nuclear power plant design and safety. Experiments with the facility involve mixing air jets within a 1x1x1.7m long glass tank at atmospheric pressure. A particle image velocimetry system measures flow velocity and turbulence quantities within the tank while a high-speed infrared camera records temperatures across the tank lid. The tandem of high fidelity thermal and turbulence data is particularly useful for benchmarking transient heat transfer phenomena such as thermal striping. This paper describes the MAX facility, preliminary data obtained during shakedown tests, and the results of companion CFD calculations employing RANS-based Star-CCM+ and large eddy simulations with Nek 5000.

Validity of the reduced Salpeter equation  

Science Journals Connector (OSTI)

We adapt a general method to solve both the full and reduced Salpeter equations and systematically explore the conditions under which these two equations give equivalent results in meson dynamics. The effects of consistituent mass, angular momentum state, type of interactions, and the nature of confinement are all considered in an effort to clearly delineate the range of validity of the reduced Salpeter approximations. We find that for J?0 the solutions are strikingly similar for all constituent masses. For zero angular momentum states the full and reduced Salpeter equations give different results for a small quark mass, especially with a large additive constant coordinate space potential. We also show that 1/m corrections to heavy-light energy levels can be accurately computed with the reduced equation. 1995 The American Physical Society.

Validating agent based models through virtual worlds.  

SciTech Connect (OSTI)

As the US continues its vigilance against distributed, embedded threats, understanding the political and social structure of these groups becomes paramount for predicting and dis- rupting their attacks. Agent-based models (ABMs) serve as a powerful tool to study these groups. While the popularity of social network tools (e.g., Facebook, Twitter) has provided extensive communication data, there is a lack of ne-grained behavioral data with which to inform and validate existing ABMs. Virtual worlds, in particular massively multiplayer online games (MMOG), where large numbers of people interact within a complex environ- ment for long periods of time provide an alternative source of data. These environments provide a rich social environment where players engage in a variety of activities observed between real-world groups: collaborating and/or competing with other groups, conducting battles for scarce resources, and trading in a market economy. Strategies employed by player groups surprisingly re ect those seen in present-day con icts, where players use diplomacy or espionage as their means for accomplishing their goals. In this project, we propose to address the need for ne-grained behavioral data by acquiring and analyzing game data a commercial MMOG, referred to within this report as Game X. The goals of this research were: (1) devising toolsets for analyzing virtual world data to better inform the rules that govern a social ABM and (2) exploring how virtual worlds could serve as a source of data to validate ABMs established for analogous real-world phenomena. During this research, we studied certain patterns of group behavior to compliment social modeling e orts where a signi cant lack of detailed examples of observed phenomena exists. This report outlines our work examining group behaviors that underly what we have termed the Expression-To-Action (E2A) problem: determining the changes in social contact that lead individuals/groups to engage in a particular behavior. Results from our work indicate that virtual worlds have the potential for serving as a proxy in allocating and populating behaviors that would be used within further agent-based modeling studies.

Report on a workshop concerning code validation  

SciTech Connect (OSTI)

The design of wind turbine components is becoming more critical as turbines become lighter and more dynamically active. Computer codes that will reliably predict turbine dynamic response are, therefore, more necessary than before. However, predicting the dynamic response of very slender rotating structures that operate in turbulent winds is not a simple matter. Even so, codes for this purpose have been developed and tested in North America and in Europe, and it is important to disseminate information on this subject. The purpose of this workshop was to allow those involved in the wind energy industry in the US to assess the progress invalidation of the codes most commonly used for structural/aero-elastic wind turbine simulation. The theme of the workshop was, ``How do we know it`s right``? This was the question that participants were encouraged to ask themselves throughout the meeting in order to avoid the temptation of presenting information in a less-than-critical atmosphere. Other questions posed at the meeting are: What is the proof that the codes used can truthfully represent the field data? At what steps were the codes tested against known solutions, or against reliable field data? How should the designer or user validate results? What computer resources are needed? How do codes being used in Europe compare with those used in the US? How does the code used affect industry certification? What can be expected in the future?

Normal modes, virtual modes, and alternative representations in the theory of surface?duct sound propagation  

Science Journals Connector (OSTI)

This paper presents a theoretical study of sound propagation in an ocean?surface duct. It deals with several aspects of the theory from a point of view which has not heretofore been taken in the analyses of this problem. The model used to describe a duct assumes the ocean surface to be smooth and the square of the refractive index to be bilinear. Alternative representations of the sound field excited by a point source are derived the two playing the most significant role in this paper being the residue series and the normal?mode representation. It is shown that the depth functions of the residue series do not form a complete set as those of a normal?mode representation must and that the normal?mode spectrum is continuous rather than discrete. The completeness properties of the normal?mode functions are then utilized in a study of the energy?trapping capabilities of the duct. In this connection virtual modes are introduced and shown to lead naturally to the derivation of a leakage coefficient characteristic of the exponential leakage of energy out of the duct with increasing range. In addition a cutoff?frequency criterion useful in determining when a surface duct can trap energy is derived.

Puget Sound Area Electric Reliability Plan : Appendix E, Transmission Reinforcement Analysis.  

SciTech Connect (OSTI)

The purpose of this appendix to the draft environmental impact statement (EIS) report is to provide an update of the latest study work done on transmission system options for the Puget Sound Area Electric Reliability Plan. Also included in the attachments to the EIS are 2 reports analyzing the voltage stability of the Puget Sound transmission system and a review by Power Technologies, Inc. of the BPA voltage stability analysis and reactive options. Five transmission line options and several reactive options are presently being considered as possible solutions to the PSAFRP by the Transmission Team. The first two line options would be built on new rights-of way adjacent (as much as possible) to existing corridors. The reactive options would optimize the existing transmission system capability by adding new stations for series capacitors and/or switchgear. The other three line options are rebuilds or upgrades of existing cross mountain transmission lines. These options are listed below and include a preliminary assessment of the additional transmission system reinforcement required to integrate the new facilities into the existing transmission system. Plans were designed to provide at least 500 MVAR reactive margin.

Concentration and toxicity of sea-surface contaminants in Puget Sound  

SciTech Connect (OSTI)

The Marine Research Laboratory conducted studies during CY 1985 to evaluate the effects of sea-surface contamination on the reproductive success of a valued marine species. Microlayer and bulk water samples were collected from a rural bay, central Puget Sound, and three urban bays and analyzed for a number of metal and organic contaminants as well as for densities of neuston and plankton organisms. Fertilized neustonic eggs of sand sole (Psettichthys melanostictus) were exposed to the same microlayer samples during their first week of embryonic and larval development. Also, we evaluated the effects of microlayer extracts on the growth of trout cell cultures. Compared to rural sites, urban bays generally contained lower densities of neustonic flatfish eggs during the spawning season. Also, in contrast to the rural sites or the one central Puget Sound site, approximately half of the urban bay microlayer samples resulted in significant increases in embryo mortality (up to 100%), kyphosis (bent spine abnormalities) in hatched larvae, increased anaphase aberrations in developing embryos, and decreased trout cell growth. The toxic samples generally contained high concentrations of polycyclic aromatic and/or chlorinated hydrocarbons and/or potentially toxic metals. In some cases, concentrations of contaminants on the sea surface exceeded water-quality criteria by several orders of magnitude. Several samples of subsurface bulk water collected below highly contaminated surfaces showed no detectable contamination or toxicity.

Use of Advanced Meteorological Model Output for Coastal Ocean Modeling in Puget Sound  

SciTech Connect (OSTI)

It is a great challenge to specify meteorological forcing in estuarine and coastal circulation modeling using observed data because of the lack of complete datasets. As a result of this limitation, water temperature is often not simulated in estuarine and coastal modeling, with the assumption that density-induced currents are generally dominated by salinity gradients. However, in many situations, temperature gradients could be sufficiently large to influence the baroclinic motion. In this paper, we present an approach to simulate water temperature using outputs from advanced meteorological models. This modeling approach was applied to simulate annual variations of water temperatures of Puget Sound, a fjordal estuary in the Pacific Northwest of USA. Meteorological parameters from North American Region Re-analysis (NARR) model outputs were evaluated with comparisons to observed data at real-time meteorological stations. Model results demonstrated that NARR outputs can be used to drive coastal ocean models for realistic simulations of long-term water-temperature distributions in Puget Sound. Model results indicated that the net flux from NARR can be further improved with the additional information from real-time observations.

Heavy metals in the eastern oyster, Crassostrea virginica, of the Mississippi Sound  

SciTech Connect (OSTI)

Levels of metals in oysters in the Sound are of profound interest not only because they document those geographic areas where metal pollution levels may be problematic but because they may disclose possible problems to consumers of oysters. At the present time objective federal standards for heavy metals in oysters and other seafood are restricted to mercury. The closure of Mississippi oyster reefs has been predicated upon bacteriological standards with little if any attention paid to heavy metals. A study of fourteen metals in oysters of the Sound was began in 1988 with objectives differing from that of the Status and Trends Program (STP) in three ways. STP levels are reported on dry weight basis of composites from three sites. In the present study, oysters were analyzed and reported on wet weight basis. Additionally analyses were made of individual specimens to indicate expected specimen to specimen variations and were conducted on oysters from the three STP and two other important oyster reef sites. In the future three or more additional sites will be added to this continuing survey effort. Metals chosen for this study were lead (Pb), cadmium (Cd), iron (Fe), copper (Cu), cobalt (Co), manganese (Mn), zinc (Zn), silver (Ag), nickel (Ni), mercury (Hg), aluminum (Al), chromium (Cr), molybdenum (Mo), and vanadium (V).

Sounding Brighton: Update on soundscape planning with a user centric approach  

Science Journals Connector (OSTI)

The potential of soundscape planning has been widely illustrated in recent years. Sounding Brighton is a collaborative initiative pioneered by the Noise Abatement Society and Brighton and Hove City Council in 2010 with the support of the former COST Action TD0804. The project continues and is exploring the positive effects soundscapes can have on health wellbeing and quality of life. It recently undertook a city-wide soundscape survey and interviews leading to West Street Story a night-noise intervention pilot to gauge whether ambient soundscapes might act as an antidote to the Saturday night drinking culture seen on the city's most dangerous street and the follow on project: West Street Tunnel investigating the same approach in a disused pedestrian subway. The work has also gained inclusion in the Masterplan for the redevelopment of the city center leading to its willingness to participate in and its acceptance into the European Union funded FP7 SONORUS project looking at holistic ways to include urban sound planning into city planning. This paper will provide an update of the project and its results so far.

Puget Sound Area Electric Reliability Plan. Appendix E: Transmission Reinforcement Analysis : Draft Environmental Impact Statement.  

SciTech Connect (OSTI)

Five transmission line options and several reactive (voltage support) options are presently being considered as possible solutions to the PSAERP by the Transmission Team. The first two line options would be built on new rights-of way adjacent (as much as possible) to existing corridors. The reactive options would optimize the existing transmission system capability by adding new stations for series capacitors and/or switchgear. The other three line options are rebuilds or upgrades of existing cross mountain transmission lines. These options are listed below and include a preliminary assessment of the additional transmission system reinforcement required to integrate the new facilities into the existing transmission system. These options were derived from earlier study work that was summarized in Puget Sound Reinforcement Transmission Options'' and New Cross Mountain Transmission Line Alternative: The Crosstie'', which are attached. The initial Transmission Options study report recognized the value to system performance of adding an entirely new circuit rather than rebuilding an existing one. However, siting realities require that rebuild options be considered. Typically, the most attractive rebuild options would be the lowest capacity (lowest voltage) circuits. But because of corridor location, length and terminal proximity, the rebuild options listed below appear to be the most promising. Schematic diagrams and QV Curves of each option are also attached. It should be noted that Snoqualmie and Echo Lake refer to the same station east of Puget Sound and Naneum and Kittitas refer to the same station in the Ellensburg area. 100 figs., 20 tabs.

Testing Thermo-acoustic Sound Generation in Water with Proton and Laser Beams  

E-Print Network [OSTI]

Experiments were performed at a proton accelerator and an infrared laser acility to investigate the sound generation caused by the energy deposition of pulsed particle and laser beams in water. The beams with an energy range of 1 PeV to 400 PeV per proton beam spill and up to 10 EeV for the laser pulse were dumped into a water volume and the resulting acoustic signals were recorded with pressure sensitive sensors. Measurements were performed at varying pulse energies, sensor positions, beam diameters and temperatures. The data is well described by simulations based on the thermo-acoustic model. This implies that the primary mechanism for sound generation by the energy deposition of particles propagating in water is the local heating of the media giving rise to an expansion or contraction of the medium resulting in a pressure pulse with bipolar shape. A possible application of this effect would be the acoustical detection of neutrinos with energies greater than 1 EeV.

Measurement of sound speed vs. depth in South Pole ice: pressure waves and shear waves  

SciTech Connect (OSTI)

We have measured the speed of both pressure waves and shear waves as a function of depth between 80 and 500 m depth in South Pole ice with better than 1% precision. The measurements were made using the South Pole Acoustic Test Setup (SPATS), an array of transmitters and sensors deployed in the ice at the South Pole in order to measure the acoustic properties relevant to acoustic detection of astrophysical neutrinos. The transmitters and sensors use piezoceramics operating at {approx}5-25 kHz. Between 200 m and 500 m depth, the measured profile is consistent with zero variation of the sound speed with depth, resulting in zero refraction, for both pressure and shear waves. We also performed a complementary study featuring an explosive signal propagating vertically from 50 to 2250 m depth, from which we determined a value for the pressure wave speed consistent with that determined for shallower depths, higher frequencies, and horizontal propagation with the SPATS sensors. The sound speed profile presented here can be used to achieve good acoustic source position and emission time reconstruction in general, and neutrino direction and energy reconstruction in particular. The reconstructed quantities could also help separate neutrino signals from background.

Validation of an Integrated Hydrogen Energy Station  

SciTech Connect (OSTI)

This report presents the results of a 10-year project conducted by Air Products and Chemicals, Inc. (Air Products) to determine the feasibility of coproducing hydrogen with electricity. The primary objective was to demonstrate the technical and economic viability of a hydrogen energy station using a high-temperature fuel cell designed to produce power and hydrogen. This four-phase project had intermediate go/no-go decisions and the following specific goals: ?¢???¢ Complete a technical assessment and economic analysis of the use of high-temperature fuel cells, including solid oxide and molten carbonate, for the co-production of power and hydrogen (energy park concept). ?¢???¢ Build on the experience gained at the Las Vegas H2 Energy Station and compare/contrast the two approaches for co-production. ?¢???¢ Determine the applicability of co-production from a high-temperature fuel cell for the existing merchant hydrogen market and for the emerging hydrogen economy. ?¢???¢ Demonstrate the concept on natural gas for six months at a suitable site with demand for both hydrogen and electricity. ?¢???¢ Maintain safety as the top priority in the system design and operation. ?¢???¢ Obtain adequate operational data to provide the basis for future commercial activities, including hydrogen fueling stations. Work began with the execution of the cooperative agreement with DOE on 30 September 2001. During Phase 1, Air Products identified high-temperature fuel cells as having the potential to meet the coproduction targets, and the molten carbonate fuel cell system from FuelCell Energy, Inc. (FuelCell Energy) was selected by Air Products and DOE following the feasibility assessment performed during Phase 2. Detailed design, construction and shop validation testing of a system to produce 250 kW of electricity and 100 kilograms per day of hydrogen, along with site selection to include a renewable feedstock for the fuel cell, were completed in Phase 3. The system also completed six months of demonstration operation at the wastewater treatment facility operated by Orange County Sanitation District (OCSD, Fountain Valley, CA). As part of achieving the objective of operating on a renewable feedstock, Air Products secured additional funding via an award from the California Air Resources Board. The South Coast Air Quality Management District also provided cost share which supported the objectives of this project. System operation at OCSD confirmed the results from shop validation testing performed during Phase 3. Hydrogen was produced at rates and purity that met the targets from the system design basis, and coproduction efficiency exceeded the 50% target set in conjunction with input from the DOE. Hydrogen production economics, updated from the Phase 2 analysis, showed pricing of $5 to $6 per kilogram of hydrogen using current gas purification systems. Hydrogen costs under $3 per kilogram are achievable if next-generation electrochemical separation technologies become available.

Method and apparatus for ultrasonic doppler velocimetry using speed of sound and reflection mode pulsed wideband doppler  

DOE Patents [OSTI]

According to the present invention, a method and apparatus rely upon tomographic measurement of the speed of sound and fluid velocity in a pipe. The invention provides a more accurate profile of velocity within flow fields where the speed of sound varies within the cross-section of the pipe. This profile is obtained by reconstruction of the velocity profile from the local speed of sound measurement simultaneously with the flow velocity. The method of the present invention is real-time tomographic ultrasonic Doppler velocimetry utilizing a to plurality of ultrasonic transmission and reflection measurements along two orthogonal sets of parallel acoustic lines-of-sight. The fluid velocity profile and the acoustic velocity profile are determined by iteration between determining a fluid velocity profile and measuring local acoustic velocity until convergence is reached.

Radcalc for Windows validation and benchmark study  

SciTech Connect (OSTI)

Radcalc for Windows, version 2.01 (Radcalc), is a software program developed by Waste Management Federal Services, Inc., Northwest Operations for the US Department of Energy. It is used to generate selected transportation and packaging data necessary for the shipment of radioactive waste materials. Among its applications are the classification of waste per US Department of Transportation regulations, the calculation of heat and daughter products generated as a result of radioactive decay, and the calculation of the radiolytic production of hydrogen gas. The Radcalc program has been extensively tested and validated by comparison of each Radcalc algorithm to hand calculations. An opportunity to benchmark Radcalc hydrogen gas generation calculations to experimental data arose when the Rocky Flats Environmental Technology Site (REFETS) residue stabilization program collected hydrogen gas generation data to determine compliance with requirements for shipment of waste in the TRUPACT-II. Previously, Radcalc had been benchmarked to residue/waste drums tested at RFETS containing contaminated solid inorganic materials in plastic bags. In this paper Radcalc is compared with data collected for contaminated solid organic waste. The contamination is predominantly due to plutonium and americium isotopes. The information provided by RFETS includes decay heat, hydrogen gas generation rates, calculated hydrogen G{sub eff} values (molecules of hydrogen formed per 100-eV decay heat energy released), and waste material. Radcalc cases are run using RFETS G{sub eff} values, TRUPACT-II G values, and dose-dependent G values. Work on calculating the radiolytic production of hydrogen gas and related increase in package pressure has also been performed at the Savannah River Site (SRS) in support of efforts to ship nuclear materials in the 9975 package. The calculations made at SRS are contained in an Excel spreadsheet. The SRS model has been compared with experimental data collected at SRS and at Los Alamos National Laboratory.

Roll-up of validation results to a target application.  

SciTech Connect (OSTI)

Suites of experiments are preformed over a validation hierarchy to test computational simulation models for complex applications. Experiments within the hierarchy can be performed at different conditions and configurations than those for an intended application, with each experiment testing only part of the physics relevant for the application. The purpose of the present work is to develop methodology to roll-up validation results to an application, and to assess the impact the validation hierarchy design has on the roll-up results. The roll-up is accomplished through the development of a meta-model that relates validation measurements throughout a hierarchy to the desired response quantities for the target application. The meta-model is developed using the computation simulation models for the experiments and the application. The meta-model approach is applied to a series of example transport problems that represent complete and incomplete coverage of the physics of the target application by the validation experiments.

Puget Sound Tidal Energy In-Water Testing and Development Project Final Technical Report  

SciTech Connect (OSTI)

Tidal energy represents potential for the generation of renewable, emission free, environmentally benign, and cost effective energy from tidal flows. A successful tidal energy demonstration project in Puget Sound, Washington may enable significant commercial development resulting in important benefits for the northwest region and the nation. This project promoted the United States Department of Energyâ??s Wind and Hydropower Technologies Programâ??s goals of advancing the commercial viability, cost-competitiveness, and market acceptance of marine hydrokinetic systems. The objective of the Puget Sound Tidal Energy Demonstration Project is to conduct in-water testing and evaluation of tidal energy technology as a first step toward potential construction of a commercial-scale tidal energy power plant. The specific goal of the project phase covered by this award was to conduct all activities necessary to complete engineering design and obtain construction approvals for a pilot demonstration plant in the Admiralty Inlet region of the Puget Sound. Public Utility District No. 1 of Snohomish County (The District) accomplished the objectives of this award through four tasks: Detailed Admiralty Inlet Site Studies, Plant Design and Construction Planning, Environmental and Regulatory Activities, and Management and Reporting. Pre-Installation studies completed under this award provided invaluable data used for site selection, environmental evaluation and permitting, plant design, and construction planning. However, these data gathering efforts are not only important to the Admiralty Inlet pilot project. Lessons learned, in particular environmental data gathering methods, can be applied to future tidal energy projects in the United States and other parts of the world. The District collaborated extensively with project stakeholders to complete the tasks for this award. This included Federal, State, and local government agencies, tribal governments, environmental groups, and others. All required permit and license applications were completed and submitted under this award, including a Final License Application for a pilot hydrokinetic license from the Federal Energy Regulatory Commission. The tasks described above have brought the project through all necessary requirements to construct a tidal pilot project in Admiralty Inlet with the exception of final permit and license approvals, and the selection of a general contractor to perform project construction.

Potential use of feebate systems to foster environmentally sound urban waste management  

SciTech Connect (OSTI)

Waste treatment facilities are often shared among different municipalities as a means of managing wastes more efficiently. Usually, management costs are assigned to each municipality depending on the size of the population or total amount of waste produced, regardless of important environmental aspects such as per capita waste generation or achievements in composting or recycling. This paper presents a feebate (fee+rebate) system aimed to foster urban waste reduction and recovery. The proposal suggests that municipalities achieving better results in their waste management performance (from an ecological viewpoint) be recompensated with a rebate obtained from a fee charged to those municipalities that are less environmentally sound. This is a dynamic and flexible instrument that would positively encourage municipalities to reduce waste whilst increasing the recycling.

Photoacoustically Measured Speeds of Sound of Liquid HBO2: On Unlocking the Fuel Potential of Boron  

SciTech Connect (OSTI)

Elucidation of geodynamic, geochemical, and shock induced processes is often limited by challenges to accurately determine molecular fluid equations of state (EOS). High pressure liquid state reactions of carbon species underlie physiochemical mechanisms such as differentiation of planetary interiors, deep carbon sequestration, propellant deflagration, and shock chemistry. Here we introduce a versatile photoacoustic technique developed to measure accurate and precise speeds of sound (SoS) of high pressure molecular fluids and fluid mixtures. SoS of an intermediate boron oxide, HBO{sub 2} are measured up to 0.5 GPa along the 277 C isotherm. A polarized Exponential-6 interatomic potential form, parameterized using our SoS data, enables EOS determinations and corresponding semi-empirical evaluations of > 2000 C thermodynamic states including energy release from bororganic formulations. Our thermochemical model propitiously predicts boronated hydrocarbon shock Hugoniot results.

Some Applications of Meteorology to Underwater Ambient Noise Studies in Block Island Sound  

Science Journals Connector (OSTI)

Turbulent atmospheric boundary?layer theory is applied to wind observations made over a shallow?water embayment to explain variations in ambient noise levels. Broad?band ambient?noise data for sea states up to 3 obtained at a fixed receiving site are presented for a shallow water acoustic test range in Block IslandSound. Hourly wind?speed averages are analyzed by means of spectra and covariance functions in order to compare the frequency composition of the acoustic and meteorological data. The power spectrum computed from the record of ambient noise pressure level as a function of time has significant peaks centered on frequencies of 0.04 and 0.10. Similar peaks at the corresponding frequencies are present in the spectra of wind speeds. The results of this experiment suggest that for wind speed fluctuations of less than 0.33 nonlinear effects of the wind are relatively unimportant in the generation of ambient noise.

Sustainability at Navistar: a model distinguished by sustainable innovation, proactive product stewardship, and sound science  

Science Journals Connector (OSTI)

While corporate sustainability is interpreted broadly to mean ensuring success in the present without compromising the future, a well-accepted workable definition has remained elusive. Sustainability is often defined using a set of criteria or metrics that address the recognised environmental, social, and economic pillars of sustainability. However, standard metrics fail to account for how companies deal with operational challenges to their sustainability and viability. As a 175 year old diesel engine manufacturer, Navistar, Inc. has developed a model to address not only the three pillars of sustainability but also its significant business challenges, including those related to health concerns over its diesel products and environmental and employee legacies. Featuring a commitment to sustainable innovation and product stewardship and reliance on sound science, Navistar's sustainability model has evolved in response to its unique operating environment. This model illustrates the benefits of designing sustainability strategies to address specific business challenges rather than a standard set of criteria.

Pressure Dependence of High?Frequency Sound Attenuation in the Deep Pacific Ocean  

Science Journals Connector (OSTI)

Vertical and horizontal acoustic paths located in the Pacific Ocean between depths of 910 and 3350 m have been utilized to determine the attenuation of sound at a nominal frequency of 75 kHz. Results from these two different geometries show that predicted values exceed the observed magnitudes of acoustic attenuation at this frequency and at these depths. At 3350 m the predicted value is 22.7 dB/km vs a measured value of 13.30.5 dB/km a discrepancy of more than 9 dB. Furthermore increasing pressure reduces the attenuation a fact which supports the work of Fisher [J. Acoust. Soc. Amer. 38 805 (1965)] in contrast to that of Kester and Pytkowicz [Geochimica et Cosmochimica Acta 34 1039 (1970)]. However the amount of reduction is larger than previously suspected by more than 80% [This paper represents results of research sponsored by the Office of Naval Research.

Shift in the longitudinal sound velocity due to sliding charge-density waves  

Science Journals Connector (OSTI)

The nonlinear conductivity observed for moderate electric fields in NbSe3, TaS3, (TaS4)2I, and K0.3MoO3 below the charge-density-wave-transition is believed to be due to the sliding of the charge-density waves. The sliding motion leads to a Doppler shift of the x-ray diffraction peaks, but this effect has not yet been resolved. We show here that besides the Doppler shift, a sliding incommensurate charge-density wave causes a change in the longitudinal sound velocity of the crystal that is linear in the charge-density-wave velocity. The resulting anisotropic shift is estimated in a mean-field approximation and found to be experimentally observable.

To support marine ecological resource management and emergency response and to enhance scientific understanding of physical and biogeochemical processes in Puget Sound, a real-time Puget Sound Operational Forecast System (PS-OFS) was developed by the Coastal Ocean Dynamics & Ecosystem Modeling group (CODEM) of Pacific Northwest National Laboratory (PNNL). PS-OFS employs the state-of-the-art three-dimensional coastal ocean model and closely follows the standards and procedures established by National Oceanic and Atmospheric Administration (NOAA) National Ocean Service (NOS). PS-OFS consists of four key components supporting the Puget Sound Circulation and Transport Model (PS-CTM): data acquisition, model execution and product archive, model skill assessment, and model results dissemination. This paper provides an overview of PS-OFS and its ability to provide vital real-time oceanographic information to the Puget Sound community. PS-OFS supports pacific northwest regions growing need for a predictive tool to assist water quality management, fish stock recovery efforts, maritime emergency response, nearshore land-use planning, and the challenge of climate change and sea level rise impacts. The structure of PS-OFS and examples of the system inputs and outputs, forecast results are presented in details.

Validation of the G-PASS code : status report.  

SciTech Connect (OSTI)

Validation is the process of determining whether the models in a computer code can describe the important phenomena in applications of interest. This report describes past work and proposed future work for validating the Gas Plant Analyzer and System Simulator (G-PASS) code. The G-PASS code was developed for simulating gas reactor and chemical plant system behavior during operational transients and upset events. Results are presented comparing code properties, individual component models, and integrated system behavior against results from four other computer codes. Also identified are two experiment facilities nearing completion that will provide additional data for individual component and integrated system model validation. The main goal of the validation exercise is to ready a version of G-PASS for use as a tool in evaluating vendor designs and providing guidance to vendors on design directions in nuclear-hydrogen applications.

Verification and validation of RADMODL Version 1.0  

SciTech Connect (OSTI)

RADMODL is a system of linked computer codes designed to calculate the radiation environment following an accident in which nuclear materials are released. The RADMODL code and the corresponding Verification and Validation (V&V) calculations (Appendix A), were developed for Westinghouse Savannah River Company (WSRC) by EGS Corporation (EGS). Each module of RADMODL is an independent code and was verified separately. The full system was validated by comparing the output of the various modules with the corresponding output of a previously verified version of the modules. The results of the verification and validation tests show that RADMODL correctly calculates the transport of radionuclides and radiation doses. As a result of this verification and validation effort, RADMODL Version 1.0 is certified for use in calculating the radiation environment following an accident.

Multi-terminal Subsystem Model Validation for Pacific DC Intertie  

SciTech Connect (OSTI)

this paper proposes to validate dynamic model of Pacific DC Intertie with the concept of hybrid simulation by combing simulation with PMU measurements. The Playback function available in GE PSLF is adopted for hybrid simulation. It is demonstrated for the first time the feasibility of using Playback function on multi-terminal subsystem. Sensitivity studies are also presented as a result of common PMU measurement quality problem, ie, offset noise and time synchronization. Results indicate a good tolerance of PDCI model generally. It is recommended that requirements should apply to phasor measurements in model validation work to ensure better analysis. Key parameters are identified based on impact of value change to model behavior. Two events are employed for preliminary model validation with PMU measurements. Suggestions are made for PDCI model validation work in the future.

An extensive system of computer codes is used at Argonne National Laboratory to analyze whole-plant transient behavior of the Experimental Breeder Reactor 2. Three of these codes, NATDEMO/HOTCHAN, SASSYS, and DSNP have been validated with data from reactor transient tests. The validated codes are the foundation of safety analyses and pretest predictions for the continuing design improvements and experimental programs in EBR-II, and are also valuable tools for the analysis of innovative reactor designs.
