FLORIDA TOWER FOOTPRINT EXPERIMENTS  

SciTech Connect

The Florida Footprint experiments were a series of field programs in which perfluorocarbon tracers were released in different configurations centered on a flux tower to generate a data set that can be used to test transport and dispersion models. These models are used to determine the sources of the CO{sub 2} that cause the fluxes measured at eddy covariance towers. Experiments were conducted in a managed slash pine forest, 10 km northeast of Gainesville, Florida, in 2002, 2004, and 2006 and in atmospheric conditions that ranged from well mixed, to very stable, including the transition period between convective conditions at midday to stable conditions after sun set. There were a total of 15 experiments. The characteristics of the PFTs, details of sampling and analysis methods, quality control measures, and analytical statistics including confidence limits are presented. Details of the field programs including tracer release rates, tracer source configurations, and configuration of the samplers are discussed. The result of this experiment is a high quality, well documented tracer and meteorological data set that can be used to improve and validate canopy dispersion models.

Concentrating Solar Power Tower System Basics Concentrating Solar Power Tower System Basics Concentrating Solar Power Tower System Basics August 20, 2013 - 5:06pm Addthis In power tower concentrating solar power systems, numerous large, flat, sun-tracking mirrors, known as heliostats, focus sunlight onto a receiver at the top of a tall tower. A heat-transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. Some power towers use water/steam as the heat-transfer fluid. Other advanced designs are experimenting with molten nitrate salt because of its superior heat-transfer and energy-storage capabilities. Individual commercial plants can be sized to produce up to 200 megawatts of electricity. Illustration of a power tower power plant. Sunlight is shown reflecting off a series of heliostats surrounding the tower and onto the receiver at the top of the tower. The hot heat-transfer fluid exiting from the receiver flows down the tower, into a feedwater reheater, and then into a turbine, which generates electricity that is fed into the power grid. The cool heat-transfer fluid exiting the turbine flows into a steam condenser to be cooled and sent back up the tower to the receiver.

Cooling tower waste reduction  

SciTech Connect

At Lawrence Livermore National Laboratory (LLNL), the two main cooling tower systems (central and northwest) were upgraded during the summer of 1997 to reduce the generation of hazardous waste. In 1996, these two tower systems generated approximately 135,400 lbs (61,400 kg) of hazardous sludge, which is more than 90 percent of the hazardous waste for the site annually. At both, wet decks (cascade reservoirs) were covered to block sunlight. Covering the cascade reservoirs reduced the amount of chemical conditioners (e.g. algaecide and biocide), required and in turn the amount of waste generated was reduced. Additionally, at the northwest cooling tower system, a sand filtration system was installed to allow cyclical filtering and backflushing, and new pumps, piping, and spray nozzles were installed to increase agitation. the appurtenance upgrade increased the efficiency of the cooling towers. The sand filtration system at the northwest cooling tower system enables operators to continuously maintain the cooling tower water quality without taking the towers out of service. Operational costs (including waste handling and disposal) and maintenance activities are compared for the cooling towers before and after upgrades. Additionally, the effectiveness of the sand filter system in conjunction with the wet deck covers (northwest cooling tower system), versus the cascade reservoir covers alone (south cooling tower south) is discussed. the overall expected return on investment is calculated to be in excess of 250 percent. this upgrade has been incorporated into the 1998 DOE complex-wide water conservation project being led by Sandia National Laboratory/Albuquerque.

Cooling Towers, The Debottleneckers  

E-Print Network (OSTI)

Power generating plants and petro-chemical works are always expanding. An on-going problem is to identify and de-bottle neck restricting conditions of growth. The cooling tower is a highly visible piece of equipment. Most industrial crossflow units are large structures, Illustration 1. Big budget money and engineering time goes into gleaming stainless steel equipment and exotic process apparatus, the poor cooling tower is the ignored orphan of the system. Knowledgeable Engineers, however, are now looking into the function of the cooling tower, which is to produce colder water- and question the quality of water discharged from that simple appearing box. These cross-flow structures are quite large, ranging up to 60 feet tall with as many as 6 or more cells in a row. With cells up to 42 feet long so immense in aspect, with fans rotating, operators assume, just by appearances, that all is well, and usually pay no attention to the quality of cold water returning from the cooling tower. The boxes look sturdy, but the function of the cooling tower is repeated ignored production of water as cold as possible.

Solar power towers  

DOE Green Energy (OSTI)

The high desert near Barstow, California, has witnessed the development of this country's first two solar power towers. Solar One operated successfully from 1982 to 1988 and proved that power towers work efficiently to produce utility-scale power from sunlight. Solar Two was connected to the utility grid in 1996 and is operating today. Like its predecessor, Solar Two is rated at 10 megawatts. An upgrade of the Solar One plant, Solar Two demonstrates how solar energy can be stored in the form of heat in molten salt for power generation on demand. The experience gained with these two pilot power towers has established a foundation on which industry can develop its first commercial plants. These systems produce electricity on a large scale. They are unique among solar technologies because they can store energy efficiently and cost effectively. They can operate whenever the customer needs power, even after dark or during cloudy weather.

Abstract On the Automorphism Tower  

E-Print Network (OSTI)

In this thesis I study the automorphism tower of free nilpotent groups. Our main tool in studying the automorphism tower is to embed every group as a lattice in some Lie group. Using known rigidity results the automorphism group of the discrete group can be embedded into the automorphism group of the Lie group. This allows me to lift the description of the derivation tower of the free nilpotent Lie algebra to obtain information about the automorphism tower of the free nilpotent group. The main result in this thesis states that the automorphism tower of the free nilpotent group ?(n, d) on n generators and nilpotency class d, stabilizes after finitely many steps. If the nilpotency class is small compared to the number of generators we have that the height of the automorphism tower is at most

SunLab: Concentrating Solar Power Program Overview  

DOE Green Energy (OSTI)

DOE's Concentrating Solar Power (CSP) program is collaborating with its partners in the private sector to develop two new solar technologies -- power towers and dish/engines -- to meet the huge commercial potential for solar power. Concentrating solar power plants produce electric power by first converting the sun's energy into heat, and then to electricity in a conventional generator.

Cooling Towers, Energy Conservation Strategies  

E-Print Network (OSTI)

Cooling towers, because of their seeming simplicity, are usually orphans of the facilities operation. We are all aware that cooling towers are the step-children of the chemical process plant, electric power generating station, and refrigeration system. While our engineers are pretty well convinced of the importance of their sophisticated equipment, and rightly so, they take the cooling towers and the cold water returning from them for granted. Design Conditions are specified for the particular requirements before a cooling tower is purchased. After it is put on the line and the cold water temperature or volume becomes inadequate, they look to solutions other than the obvious. While all cooling towers are purchased to function at 100% of capability in accordance with the required Design Conditions, in actual on stream employment, the level of operation many times is lower, downwards to as much as 50% due to a variety of reasons: (1) The present service needed is now greater than the original requirements which the tower was purchased for; (2) 'Slippage' due to usage and perhaps deficient maintenance has reduced the performance of the tower over years of operation; (3) The installation could have been originally undersized due to the low bidder syndrome; and (4) New plant expansion needs colder temperatures off the tower.

Thermal performance of cooling towers  

SciTech Connect

Wet cooling towers are often used in HVAC applications to reject heat to the atmosphere. Heat rejection is accomplished within the tower by heat and mass transfer between hot water droplets and ambient air. These heat and mass transfer processes and the resulting coefficient of performance are often misunderstood and misinterpreted. To demystify these concepts, the heat and mass transfer exchange at the water droplet level are reviewed. This is followed by an analysis of an idealized spray-type tower to show how cooling tower performance is affected by fill height, water retention time, and air and water mass flow rates. Finally, the so-called coefficient of performance of cooling towers is examined.

Cooling Towers, Energy Conservation Machines  

E-Print Network (OSTI)

Cooling towers, in all too many industrial plants, are often the neglected units of the process chain which are hidden bonanzas for energy conservation and dollar savings. By lowering the entire systems temperature by the use of colder water returning from the cooling tower, greater chemical product volume can be condensed and less energy is required to run compressors. This paper will discuss two case histories and the rapid cost-effective savings thereby accruing through retrofit.

Oriented spray-assisted cooling tower  

Science Conference Proceedings (OSTI)

Apparatus useful for heat exchange by evaporative cooling when employed in conjunction with a conventional cooling tower. The arrangement includes a header pipe which is used to divert a portion of the water in the cooling tower supply conduit up stream of the cooling tower to a multiplicity of vertical pipes and spray nozzles which are evenly spaced external to the cooling tower so as to produce a uniform spray pattern oriented toward the central axis of the cooling tower and thereby induce an air flow into the cooling tower which is greater than otherwise achieved. By spraying the water to be cooled towards the cooling tower in a region external to the cooling tower in a manner such that the spray falls just short of the cooling tower basin, the spray does not interfere with the operation of the cooling tower, proper, and the-maximum increase in air velocity is achieved just above the cooling tower basin where it is most effective. The sprayed water lands on a concrete or asphalt apron which extends from the header pipe to the cooling tower basin and is gently sloped towards the cooling tower basin such that the sprayed water drains into the basin. By diverting a portion of the water to be cooled to a multiplicity of sprays external to the cooling tower, thermal performance is improved. 4 figs.

SMUD Kokhala Power Tower Study  

DOE Green Energy (OSTI)

Kokhala is the name of a new hybridized power tower design which integrates a nitrate-salt solar power tower with a gas turbine combined-cycle power plant. This integration achieves high value energy, low costs, and lower investor risk than a conventional solar only power tower plant. One of the primary advantages of this system is that it makes small power tower plants much more economically competitive with conventional power generation technologies. This paper is an overview of a study that performed a conceptual evaluation of a small (30 MWe) commercial plant suitable for the Sacramento Municipal Utility District`s (SMUD) Rancho Seco power plant site near Sacramento, California. This paper discusses the motivation for using a small hybrid solar plant and provides an overview of the analysis methodology used in the study. The results indicate that a power tower integrated with an advanced gas turbine, combined with Sacramento`s summer solar resource, could produce a low- risk, economically viable power generation project in the near future.

Sun tanning/burning  

NLE Websites -- All DOE Office Websites (Extended Search)

Sun tanning/burning Sun tanning/burning Name: Richardo Cossyleon Location: N/A Country: N/A Date: N/A Question: Why doesn't the sun affect or burn people with dark pigment in their skin? Replies: Good question! The pigment, melanin, is more toward the surface of the upper skin layer and absorbs ultraviolet rays from the Sun or artificial sources. This absorption protects the lower layers from damage and inflammation (burning). A very dark skinned person may have over a 1000X the protection from UV compared to a fair skinned person. Fair skinned people should use sun-block lotions especially early in the warm season AND keep exposure to the sun, particularly at midday, to less than 30 min. Even if a person gets a good tan, the sun's UV will age the skin over time. It will get wrinkled and develop age lines, etc. after many years of exposure. Moderation is the key!

Hydrogen Storage in Wind Turbine Towers  

DOE Green Energy (OSTI)

Low-cost hydrogen storage is recognized as a cornerstone of a renewables-hydrogen economy. Modern utility-scale wind turbine towers are typically conical steel structures that, in addition to supporting the rotor, could be used to store hydrogen. This study has three objectives: (1) Identify the paramount considerations associated with using a wind turbine tower for hydrogen storage; (2)Propose and analyze a cost-effective design for a hydrogen-storing tower; and (3) Compare the cost of storage in hydrogen towers to the cost of storage in conventional pressure vessels. The paramount considerations associated with a hydrogen tower are corrosion (in the form of hydrogen embrittlement) and structural failure (through bursting or fatigue life degradation). Although hydrogen embrittlement (HE) requires more research, it does not appear to prohibit the use of turbine towers for hydrogen storage. Furthermore, the structural modifications required to store hydrogen in a tower are not cost prohibitive.

Cooling Tower Inspection with Scuba  

E-Print Network (OSTI)

A serious problem of scale and other solid material settling in heat transfer equipment was threatening to shut down our ethylene plant. All evidence pointed to the cooling tower as the source of the contamination. Visual inspection of the cooling tower pump suction basin was accomplished by diving into the basin using SCUBA gear. It was possible to see a build-up of debris on the pump suction basket strainers and on the floor of the sumps. Also, it was discovered that one of the four baskets had been installed incorrectly. Photographs of the basket strainers were taken to aid in describing their exact condition. With the aid of SCUBA it was possible to sufficiently clean the pump sumps so that costly downtime was avoided. Likewise, using this technique, steps were taken to greatly reduce the chance for further contamination of the circulating cooling water system.

Combined-cycle power tower  

DOE Green Energy (OSTI)

This paper evaluates a new power tower concept that offers significant benefits for commercialization of power tower technology. The concept uses a molten nitrate salt centralreceiver plant to supply heat, in the form of combustion air preheat, to a conventional combined-cycle power plant. The evaluation focused on first commercial plants, examined three plant capacities (31, 100, and 300 MWe), and compared these plants with a solar-only 100-MWe plant and with gas-only combined-cycle plants in the same three capacities. Results of the analysis point to several benefits relative to the solar-only plant including low energy cost for first plants, low capital cost for first plants, reduced risk with respect to business uncertainties, and the potential for new markets. In addition, the concept appears to have minimal technology development requirements. Significantly, the results show that it is possible to build a first plant with this concept that can compete with existing gas-only combined-cycle plants.

Best Management Practice: Cooling Tower Management Best Management Practice: Cooling Tower Management Best Management Practice: Cooling Tower Management October 8, 2013 - 9:39am Addthis Cooling towers regulate temperature by dissipating heat from recirculating water used to cool chillers, air-conditioning equipment, or other process equipment. Heat is rejected from the tower primarily through evaporation. Therefore, by design, cooling towers consume significant amounts of water. Overview The thermal efficiency and longevity of the cooling tower and equipment used to cool depend on the proper management of water recirculated through the tower. Water leaves a cooling tower system in any one of four ways: Evaporation: This is the primary function of the tower and is the method that transfers heat from the cooling tower system to the

Sun-bleached hair

Sun-bleached hair Sun-bleached hair Name: Tami Thein, Kelly Frazier, Liz Valente 8 Glen Crest Jr. High Status: N/A Age: N/A Location: N/A Country: N/A Date: N/A Question: Why does some hair change color when exposed to the sun? We checked archives in biology and general science. Replies: This is a good question for a chemist but I'll try and give you a partial answer. Hair contains pigments that are vulnerable to chemical modification by a process called photobleaching. Rearrangements in the pigments molecular structure changes the way light is absorbed and reflected. A similar effect can be caused by chemical bleaching by the hair stylist or from chlorine in a swimming pool by a process called chemical bleaching. The sun may also change the water content of the hair and this can cause subtle color changes by changing the relative density of the color pigments. Try the chemistry board for a more complete answer. Don't let your roots show!

Noise from cooling towers of power parks  

SciTech Connect

A study is presented of the noise pollution problem for large power parks proposed for the future. Such parks might have an area of about 75 sq. miles, and a generating capacity up to 48000 MW. A comparative analysis has been done for natural and mechanical-draft wet towers as the major sources of acoustic power. Noise radiation from single isolated towers as well as from a dispersed array of towers has been considered for both types of cooling systems. Major noise attenuation effects considered are due to the atmospheric absorption and A- weighting. Conditions of 60F and 70 percent relative humidity in a still atmosphere have been assumed. (auth)

CCD Camera Calibration based on the Suns Images  

E-Print Network (OSTI)

A Nikon D70s Digital camera with resolution of 6M, equipped with a narrow angle Nikkor 85 mm f/1.8D lens and suitable filters; was calibrated successfully, by two sets of the sun's images. Each set was taken while the cameras orientation was held unchanged for more than a hour. During this time the suns image cross the cameras field of view from left to right and thirty photographs were taken at fixed known time intervals, controlled by a GPS receiver that was used as an intervalometer. The camera was held so that the suns trajectory during the first set of images was an arc approximately at the direction of the sensors lines. The suns trajectory in the second set was nearly perpendicular to it. The two trajectories pass close to the sensor center. The elements of the cameras interior orientation and its tilt angles in each set of photography were determined simultaneously by least squares adjustment procedure. Due to the big number of the suns images located in good positions, the elements in the variance-covariance matrix were small. In addition the location of the suns image was determined accurately on the digital photograph, by an edge detection techniques. As a result the RMS values of the interior orientation parameters were small. 1.

Cooling Tower Considerations for Energy Optimizations  

E-Print Network (OSTI)

Energy conservation strategies and production economies involve more than examining the cooling tower fan consumption of horse power. Colder water provides vast potentials for savings. Ask yourself, "What is the dollar and energy utilization value if I can obtain 1F colder water off my cooling tower than I am now getting?" Therefore, let us first examine the elements of the cooling tower to determine the areas of greatest potential improvement to generate that colder water. The air flow generated by the fan should first be looked at In both counterflow or crossflow towers to determine that maximum flow is available through pitching fans up to within the motor plate amperage limitations and fan stall point calculations. If applicable, new fiberglass state of the art fans can be installed and additional motor horse power added. However, the most dramatic improvement that can be obtained in producing colder water is to retrofit modern film fill to replace the old fashioned wood splash bar slats.

Technologies that enable wind turbines to capture more energy at a given site have the potential to reduce the overall cost of energy, thereby making wind power more competitive against conventional power generation. Because wind speed generally increases with height above ground, one way to increase energy capture is to elevate the rotor by means of a taller tower. To exploit this potential, a number of tall tower models are under development or have recently been introduced to the wind energy market. I...

The purpose of this letter is to submit these calculation native files. The supplemental information contained in the files on the attached CD is provided to support the NRC's review of the Shearon Harris Nuclear Power Plant Units 2 and 3 (HAR) Environmental Report (ER), but does not comply with the requirements for electronic submission in the NRC Guidance Document. The NRC staff requested the files be submitted in their native formats, required for utilization in the software employed to support the ER development. As discussed with the NRC's environmental project manager responsible for review of the HAR ER, the data provided on the attached CD are of a nature that is not easily convertible to PDF output files. Furthermore, PEC understands that converting the information to PDF output files; would not serve the underlying purpose of the submittal; i.e., to provide the raw, unprocessed data to enable reviewers to evaluate software used in the HAR application.

Wet cooling towers: rule-of-thumb design and simulation  

DOE Green Energy (OSTI)

A survey of wet cooling tower literature was performed to develop a simplified method of cooling tower design and simulation for use in power plant cycle optimization. The theory of heat exchange in wet cooling towers is briefly summarized. The Merkel equation (the fundamental equation of heat transfer in wet cooling towers) is presented and discussed. The cooling tower fill constant (Ka) is defined and values derived. A rule-of-thumb method for the optimized design of cooling towers is presented. The rule-of-thumb design method provides information useful in power plant cycle optimization, including tower dimensions, water consumption rate, exit air temperature, power requirements and construction cost. In addition, a method for simulation of cooling tower performance at various operating conditions is presented. This information is also useful in power plant cycle evaluation. Using the information presented, it will be possible to incorporate wet cooling tower design and simulation into a procedure to evaluate and optimize power plant cycles.

Optimal sequencing of a cooling tower with multiple cells  

E-Print Network (OSTI)

This paper evaluates the energy savings potential of multi-cell cooling tower optimal sequencing control methods. Annual tower fan energy usage is calculated for a counter-flow tower with multiple variable-speed fans. Effectiveness-NTU tower model is employed to predict the cooling tower performance at various conditions. Natural convection when the fan is off is accounted by using an assumed airflow rate. The energy savings at five cities representing different typical climates are studied using typical meteorological year data. The results show that, if the tower capacity can be increased by 50% and 100% by running extra tower cells, the annual total fan power usage can be reduced by 44% and 61%, respectively. A cumulative saving percent curve is generated to help estimate the annual total savings percent when extra cooling tower capacity is available during only part of a year.

Loving care is paid to the compressors, condensers, and computer programs of refrigeration and air conditioning systems. When problems arise, operators and engineers run around in circles with expensive "fixes" , but historically ignore the poor orphan of the system, the cooling tower perched on the roof or located somewhere in the backyard. When cooling water is too hot, high temperature cut-outs occur and more energy must be provided to the motors to maintain the refrigeration cycle. Cooling towers: 1) are just as important a link in the chain as the other equipment; 2) are an important source of energy conservation; 3) can be big money makers; 4) operators should be aware of the potential of maximising cold water. Most towers were designed over 20 years ago and were inefficiently engineered due to cheap power and the "low bidder gets the sale" syndrome. Operating energy costs were ignored and purchasing criteria was to award the contract to the lowest bidder. All too often the low bidder - even though some of the most respected firms were involved - cut thermal corners for the sale. This paper investigates the internal elements of the typical types of cooling towers currently used, delineates their functions and shows how to upgrade them in the real world for energy savings and profitability of operation. Hard before and after statistics of costs and profits obtained through optimization of colder water by engineered thermal upgrading will be discussed. Salient points will be reenforced with on-the-job, hands-on, slides and illustrations.

Untapped Energy Savings from Cooling Towers  

E-Print Network (OSTI)

A cooling tower is often an overlooked source of easy energy savings. As long as it's running not much thought is usually given to it, but when numbers are applied to how much a degree of colder water is worth it can become a valuable and ready source of energy and monetary savings. Many of these savings can come from simple maintenance or by changing the way the tower is operated. The more dramatic savings can come from changing to advanced fill concepts. Over our 40 years of working in the cooling tower industry we have measured the effects of doing simple maintenance, the effects of blocking air flow with seemingly good ideas like maintenance walkways, the effects of nearby heat sources, and what fill changes are likely to get. We have put numbers to what a degree is worth to a large petrochemical company so you can get an idea of the magnitude of what these sometimes simple changes are actually worth. Also, we've included a way to monitor your tower for changes in performance.

Industrial processes use mechanical draft cooling towers (MDCT's) to dissipate waste heat by transferring heat from water to air via evaporative cooling, which causes air humidification. The Savannah River Site (SRS) has cross-flow and counter-current MDCT's consisting of four independent compartments called cells. Each cell has its own fan to help maximize heat transfer between ambient air and circulated water. The primary objective of the work is to simulate the cooling tower performance for the counter-current cooling tower and to conduct a parametric study under different fan speeds and ambient air conditions. The Savannah River National Laboratory (SRNL) developed a computational fluid dynamics (CFD) model and performed the benchmarking analysis against the integral measurement results to accomplish the objective. The model uses three-dimensional steady-state momentum, continuity equations, air-vapor species balance equation, and two-equation turbulence as the basic governing equations. It was assumed that vapor phase is always transported by the continuous air phase with no slip velocity. In this case, water droplet component was considered as discrete phase for the interfacial heat and mass transfer via Lagrangian approach. Thus, the air-vapor mixture model with discrete water droplet phase is used for the analysis. A series of parametric calculations was performed to investigate the impact of wind speeds and ambient conditions on the thermal performance of the cooling tower when fans were operating and when they were turned off. The model was also benchmarked against the literature data and the SRS integral test results for key parameters such as air temperature and humidity at the tower exit and water temperature for given ambient conditions. Detailed results will be published here.

The Sun's Shallow Meridional Circulation  

E-Print Network (OSTI)

The Sun's global meridional circulation is evident as a slow poleward flow at its surface. This flow is observed to carry magnetic elements poleward - producing the Sun's polar magnetic fields as a key part of the 11-year sunspot cycle. Current theories for the sunspot cycle assume that this surface flow is part of a circulation which sinks inward at the poles and turns equatorward at depths below 100 Mm. Here we use the advection of the Sun's convection cells by the meridional flow to map the flow velocity in latitude and depth. Our measurements show the largest cells clearly moving equatorward at depths below 35 Mm - the base of the Sun's surface shear layer. This surprisingly shallow return flow indicates the need for substantial revisions to solar/stellar dynamo theory.

The colours of the Sun  

E-Print Network (OSTI)

We compile a sample of Sun-like stars with accurate effective temperatures, metallicities and colours (from the UV to the near-IR). A crucial improvement is that the effective temperature scale of the stars has recently been established as both accurate and precise through direct measurement of angular diameters obtained with stellar interferometers. We fit the colours as a function of effective temperature and metallicity, and derive colour estimates for the Sun in the Johnson/Cousins, Tycho, Stromgren, 2MASS and SDSS photometric systems. For (B-V)_Sun, we favour the ``red'' colour 0.64 versus the ``blue'' colour 0.62 of other recent papers, but both values are consistent within the errors; we ascribe the difference to the selection of Sun-like stars versus interpolation of wider colour-Teff-metallicity relations.

Predict particle collection in spray towers  

SciTech Connect

Spray tower wet scrubbers are used for control of particulates (as well as gaseous pollutants). The author has found that in cocurrent spray scrubbers, the most important parameter in determining particle collection efficiency is inlet dust particle size, followed by (in decreasing order of importance) gas velocity, collector droplet size, liquid-to-gas ratio, and length of scrubber. In countercurrent scrubbers, the most important parameters are collector droplet size, liquid-to-gas ratio, length of scrubber, and gas velocity. Note that some of these factors are directly related to collection, and some are related indirectly. This article provides equations, based on theoretical considerations and empirical data, for predicting particle collection efficiencies. The parameter ranges covered are typical of those encountered in the practical operation of conventional spray towers that use a ``cool`` (or cooled) inlet gas stream, so the equations are applicable to many industrial spray tower systems. The results are limited based on the ranges of the parameters evaluated, and while it may be possible to extrapolate beyond that, this has not been verified. (The initial model was for a flue-gas desulfurization system at a large power station that requires both particulate removal and SO{sub 2} absorption.)

As a result all SU(N) irreducible representations are simple monomials of $(N-1)$ types of SU(N) irreducible Schwinger bosons. Further, we show that these representations are free of multiplicity problems. Thus all SU(N) representations are made as simple as SU(2).

A Microcomputer Model of Crossflow Cooling Tower Performance  

E-Print Network (OSTI)

The energy use characteristics of evaporative cooling towers are of interest because, although such towers are widely used in industry, they do require a substantial amount of energy. Evaporative cooling towers are basically large heat exchangers that use both sensible heat transfer and mass transfer to cool. The heat and mass transfer process for a crossflow cooling tower has been modeled on an Apple II microcomputer. Various heat loads or weather conditions can be imposed on a given tower to evaluate its response; moreover, a subprogram can evaluate pressure drop and motor/fan characteristics. Determination of the energy required to operate the tower enables its performance to be compared against energy-saving operations such as variable speed drive or changes in fill height or type.

Earth's Heat Source - The Sun  

E-Print Network (OSTI)

The Sun encompasses planet Earth, supplies the heat that warms it, and even shakes it. The United Nation Intergovernmental Panel on Climate Change (IPCC) assumed that solar influence on our climate is limited to changes in solar irradiance and adopted the consensus opinion of a Hydrogen-filled Sun, the Standard Solar Model (SSM). They did not consider the alternative solar model and instead adopted another consensus opinion: Anthropogenic greenhouse gases play a dominant role in climate change. The SSM fails to explain the solar wind, solar cycles, and the empirical link of solar surface activity with Earth changing climate. The alternative solar model, that was molded from an embarrassingly large number of unexpected observations revealed by space-age measurements since 1959, explains not only these puzzles but also how closely linked interactions between the Sun and its planets and other celestial bodies induce turbulent cycles of secondary solar characteristics that significantly affect Earth climate.

Application of upspray type water distribution systems in cooling towers  

SciTech Connect

The efficient and uniform distribution of the warm circulating water on to the filling of cooling towers has been the continuing goal of the tower designer. The final element in the water distribution system, the sprayer, plays an important role in achieving this objective. This paper discusses the performance and operational characteristics of a sprayer utilized in counterflow towers that directs the water leaving the sprayer nozzle in an upward direction and briefly compares its performance with that of downward sprayers. The discussion also covers relative tower economics and application data of the sprayer.

The Damaging Effects of Earthquake Excitation on Concrete Cooling Towers  

SciTech Connect

Reinforced concrete cooling towers of hyperbolic shell configuration find widespread application in utilities engaged in the production of electric power. In design of critical civil infrastructure of this type, it is imperative to consider all the possible loading conditions that the cooling tower may experience, an important loading condition in many countries is that of the earthquake excitation, whose influence on the integrity and stability of cooling towers is profound. Previous researches have shown that the columns supporting a cooling tower are sensitive to earthquake forces, as they are heavily loaded elements that do not possess high ductility, and understanding the behavior of columns under earthquake excitation is vital in structural design because they provide the load path for the self weight of the tower shell. This paper presents the results of a finite element investigation of a representative 'dry' cooling tower, using realistic horizontal and vertical acceleration data obtained from the recent and widely-reported Tabas, Naghan and Bam earthquakes in Iran. The results of both linear and nonlinear analyses are reported in the paper, the locations of plastic hinges within the supporting columns are identified and the ramifications of the plastic hinges on the stability of the cooling tower are assessed. It is concluded that for the (typical) cooling tower configuration analyzed, the columns that are instrumental in providing a load path are influenced greatly by earthquake loading, and for the earthquake data used in this study the representative cooling tower would be rendered unstable and would collapse under the earthquake forces considered.

Climate Change: The Sun's Role  

E-Print Network (OSTI)

The sun's role in the earth's recent warming remains controversial even though there is a good deal of evidence to support the thesis that solar variations are a very significant factor in driving climate change both currently and in the past. This precis lays out the background and data needed to understand the basic scientific argument behind the contention that variations in solar output have a significant impact on current changes in climate. It also offers a simple, phenomenological approach for estimating the actual-as opposed to model dependent-magnitude of the sun's influence on climate.

The Journey of the Sun  

E-Print Network (OSTI)

An analysis of the distribution and kinematics of interstellar material within 500 pc of the Sun leads to the conclusion that the galactic environment of the Sun changes with time. Consideration of evidence for interstellar gas interacting with the solar wind implies that these variations may alter the interplanetary environment of the Earth. The events causing the 10Be spikes 33,000 years and 60,000 years ago in the Antarctic ice record must be associated with the Local Fluff cloud complex, possibly due to solar encounters with structures with subparsec scale sizes. An encounter with "dense" interstellar cloud material could attenuate the solar L-alpha flux by as much as 70%, modify mesospheric chemistry, modify the magnetosphere-solar wind coupling, and alter the global electrical circuit. Prior to the entry of the Sun into the Local Fluff cloud complex, within the past 200,000 years, the galactic environment of the Sun differed radically from the environment prevailing today and expected for the near future.

Hydraulic Cooling Tower Driver- The Innovation  

E-Print Network (OSTI)

One of the weaknesses of present day cooling tower drives are fan wrecks caused by shaft couplings breaking, gear box malfunctions due to inadequate lubrication, gear tooth wear, and inaccessibility for inspection and routine maintenance. The hydro-drive eliminates these items from the drive train and puts the same electric motor HP at ground level close coupled to a hydraulic pump, filters, and oil reservoir. Hydraulic lines bring oil pressure to the hydraulic motor, which is more than 75% less weight than comparable gear boxes and presents a smooth practically trouble free performance. In this three cell installation, the original 75 horsepower motors and 18 diameter fans were cooling a total of 14,000 GPM which were CTI tested and 74.7% of capability. The upgrading and retrofit consisted of installing at ground level 100 horse power motors, 22 diameter fans, 14 high velocity recovery fan cylinders, V PVC splash bars, and high efficiency cellular drift eliminators. Testing after completion indicated a 92% tower now circulating 21,000 GPM instead of the original 14,000.

Hydrogen Storage in Wind Turbine Towers: Design Considerations; Preprint  

DOE Green Energy (OSTI)

The paramount considerations associated with a hydrogen tower are corrosion (in the form of hydrogen embrittlement) and structural failure (through bursting or fatigue life degradation). Although hydrogen embrittlement (HE) requires more research and experimentation, it does not appear to prohibit the use of turbine towers for hydrogen storage. Furthermore, the structural modifications required to store hydrogen in a tower are technically feasible. We discovered that hydrogen towers have a''crossover pressure'' at which their critical mode of failure crosses over from fatigue to bursting. The crossover pressure for many turbine towers is between 10 and 15 atm. The cost of hydrogen storage per unit of storage capacity is lowest near the crossover pressure. Above the crossover pressure, however, storage costs rise quickly.

Whither Does the Sun Rove?  

E-Print Network (OSTI)

If one asked some friends where on the horizon they should expect to see the sunrise, half of the answers would be "in the east". Of course, something analogous would happen with the sunset and the west. However, sunrise and sunset virtually never occur at these cardinal points. In fact, those answers correctly describe observations only during the equinoxes, when either autumn or spring begin. Once we recall this, the next natural question to ask ourselves is: how far from the east (or from the west) the rising (or setting) Sun is located for a given latitude of the observer and for a given day of the year. In this paper we supply some simple tools to easily visualize the angular (southward or northward) departure of the rising and setting Sun on the horizon from the east-west direction in a pictorial way, without the need of mathematics. These tools have proven a valuable resource in teaching introductory physics and astronomy courses.

Conversion Tower for Dispatchable Solar Power: High-Efficiency Solar-Electric Conversion Power Tower  

Science Conference Proceedings (OSTI)

HEATS Project: Abengoa Solar is developing a high-efficiency solar-electric conversion tower to enable low-cost, fully dispatchable solar energy generation. Abengoas conversion tower utilizes new system architecture and a two-phase thermal energy storage media with an efficient supercritical carbon dioxide (CO2) power cycle. The company is using a high-temperature heat-transfer fluid with a phase change in between its hot and cold operating temperature. The fluid serves as a heat storage material and is cheaper and more efficient than conventional heat-storage materials, like molten salt. It also allows the use of a high heat flux solar receiver, advanced high thermal energy density storage, and more efficient power cycles.

Cooling Towers--Energy Conservation Strategies Preservative Spray Treatment Maintains Cooling Tower  

E-Print Network (OSTI)

Several problems common to most industrial wood framed cooling towers can be easily controlled with annual preservative spray treatment applications to the plenum area framework and drift eliminators. It eliminates the expensive periodic repairs due to wood decay which sooner or later will occur without preservative protection. Preventing or minimizing the destructive effect of internal wood decay of the framework also avoids unexpected down time due to emergency maintenance or unexpected collapse of the main supporting framework.

Tower reactors for bioconversion of lignocellulosic material  

DOE Patents (OSTI)

An apparatus is described for enzymatic hydrolysis and fermentation of pretreated lignocellulosic material, in the form of a tower bioreactor, having mixers to achieve intermittent mixing of the material. Precise mixing of the material is important for effective heat and mass transfer requirements without damaging or denaturing the enzymes or fermenting microorganisms. The pretreated material, generally in the form of a slurry, is pumped through the bioreactor, either upwards or downwards, and is mixed periodically as it passes through the mixing zones where the mixers are located. For a thin slurry, alternate mixing can be achieved by a pumping loop which also serves as a heat transfer device. Additional heat transfer takes place through the reactor heat transfer jackets. 5 figs.

Experimental Investigation of the Padding Tower for Air Dehumidifier  

E-Print Network (OSTI)

Air conditioning with all fresh air is founded on the principle of dehumidifying by liquid desiccant. It has the characteristics of being clean, power-saving, easy to operate, and requiring low-grade heat. It is suitable for applying waste heat, and solar power as the heat source for regeneration. Hence, this system has a great latent potential for energy savings and environmental protection. The system chooses the padding tower as a dehumidifier and regenerator, which are often used in petrochemical industry. The system chooses a padding tower as a dehumidifier, and LiCl-Water as a liquid desiccant. The vapor in the air is absorbed by the spray of the LiCl solution, and then the absorbed vapor will be released by heating the absorbent. These processes form the circle of absorptive refrigeration operating in atmospheric pressure. This paper describes studies on the theory and experiment of the padding tower of the dehumidifying air conditioning, including selecting different padding and measuring the speed of the air flow and the solution flow and the pressure drop between the layers of the padding. The experimental and computational results indicate that the design parameters of the padding tower significantly influence the characteristics of the liquid desiccant air conditioning. Of these design parameters, the framework of the padding tower, ratio of the air and the concentration of the inlet solution is largest through the tower, the temperature and effects of the dehumidifying capability of the tower.

Power Tower Technology Roadmap and cost reduction plan.  

DOE Green Energy (OSTI)

Concentrating solar power (CSP) technologies continue to mature and are being deployed worldwide. Power towers will likely play an essential role in the future development of CSP due to their potential to provide dispatchable solar electricity at a low cost. This Power Tower Technology Roadmap has been developed by the U.S. Department of Energy (DOE) to describe the current technology, the improvement opportunities that exist for the technology, and the specific activities needed to reach the DOE programmatic target of providing competitively-priced electricity in the intermediate and baseload power markets by 2020. As a first step in developing this roadmap, a Power Tower Roadmap Workshop that included the tower industry, national laboratories, and DOE was held in March 2010. A number of technology improvement opportunities (TIOs) were identified at this workshop and separated into four categories associated with power tower subsystems: solar collector field, solar receiver, thermal energy storage, and power block/balance of plant. In this roadmap, the TIOs associated with power tower technologies are identified along with their respective impacts on the cost of delivered electricity. In addition, development timelines and estimated budgets to achieve cost reduction goals are presented. The roadmap does not present a single path for achieving these goals, but rather provides a process for evaluating a set of options from which DOE and industry can select to accelerate power tower R&D, cost reductions, and commercial deployment.

Use of nanofiltration to reduce cooling tower water usage.  

SciTech Connect

Nanofiltration (NF) can effectively treat cooling-tower water to reduce water consumption and maximize water usage efficiency of thermoelectric power plants. A pilot is being run to verify theoretical calculations. A side stream of water from a 900 gpm cooling tower is being treated by NF with the permeate returning to the cooling tower and the concentrate being discharged. The membrane efficiency is as high as over 50%. Salt rejection ranges from 77-97% with higher rejection for divalent ions. The pilot has demonstrated a reduction of makeup water of almost 20% and a reduction of discharge of over 50%.

Introducing an Online Cooling Tower Performance Analysis Tool  

E-Print Network (OSTI)

Cooling towers are used extensively for numerous industrial, residential, and commercial applications. Yet despite how common their uses, operators often do not know how to properly evaluate and optimize their performance. This is due to the complex and variable nature of all of the factors that can influence performance; fan speed, wind speed, sump temperature, heat load, ambient temperature, relative humidity, etc. This can be overwhelming for a regular operator resulting in many cooling towers being set to a default operating condition and forgotten. This paper will introduce a web-based cooling tower analysis tool being developed to help users understand and optimize operational efficiency. The calculations, evaluations, and models will be discussed in detail to highlight important design considerations and issues. This will include how the Merkel Theory, psychometric properties, tower types, and historical weather data are incorporated into the analysis.

Cooling-tower rebuild, treatment overhaul halt fouling  

SciTech Connect

Partial fixes over a period of time were insufficient to meet cooling requirements at this four-tower powerplant. The eventual remedy involved complete fill replacement and chemistry-program revision. Cooling-tower performance hinges on many factors. Assuming the proper water and air distribution and unhindered operation of spray nozzles, pumps, valves, etc, fill design is the key element. However, a decade of experience at Keystone station (operated by Pennsylvania Electric Co for a consortium of East Coast utilities) showed that more than just changing to a fouling-resistant fill was required to provide and maintain design performance. As described in this article, careful analysis, revision, and continuous monitoring of the chemical water-treatment program were needed as well. At each of Keystone's two units, two natural-draft, hyperbolic towers provide cooling for main-condenser circulating water and service water. The 325-ft-tall towers are counter-current flow, and measure 247 ft across the basin. Film-type fill originally installed in the towers consisted of assemblies of fiber-cement board, 9 ft deep in the center and 7 ft in the peripheral regions. Fiber-cement was also the construction material used in the drift eliminators, and in the piping connected to concrete distribution flumes within the towers.

The Tower Shielding Facility: Its glorious past  

Science Conference Proceedings (OSTI)

The Tower Shielding Facility (TSF) is the only reactor facility in the US that was designed and built for radiation-shielding studies in which both the reactor source and shield samples could be raised into the air to allow measurements to be made without interference from ground scattering or other spurious effects. The TSF proved its usefulness as many different programs were successfully completed. It became active in work for the Defense Atomic Support Agency (DASA) Space Nuclear Auxiliary Power, Defense Nuclear Agency, Liquid Metal Fast Breeder Reactor Program, the Gas-Cooled and High-Temperature Gas-Cooled Reactor programs, and the Japanese-American Shielding Program of Experimental Research, just to mention a few of the more extensive ones. The history of the TSF as presented in this report describes the various experiments that were performed using the different reactors. The experiments are categorized as to the programs which they supported and placed in corresponding chapters. The experiments are described in modest detail, along with their purpose when appropriate. Discussion of the results is minimal, but references are given to more extensive topical reports.

Wind Shear Characteristics at Central Plains Tall Towers  

Science Conference Proceedings (OSTI)

The object of this study is to analyze wind shear characteristics at tall tower sites in the Central Plains of the United States. The hub heights of modern turbines used for wind farm projects are now 70 meters (m) to 100 m above ground and some advanced turbines under development for deployment during the second half of this decade are rated at 2-5 megawatts of energy generation with rotor diameters near 100 m and hub heights of 100-120 m. These advanced turbines will take advantage of the higher wind speeds aloft to generate more wind energy. Specific knowledge of important wind shear characteristics near and at turbine hub height is needed to optimize turbine design and wind farm layout. Unfortunately, wind speed shear measurements at heights of 80-120 m were virtually nonexistent a few years ago and are still quite uncommon today. The Central Plains is a prime wind energy development region and knowledge about the wind shear characteristics will reduce uncertainty about the resource and enhance wind farm design. Previous analyses of tall tower data (Schwartz and Elliott, 2005) concentrated on data from specific states. The wind energy community has recognized the need to fill the gap of direct wind speed measurements at levels 70 m and higher above the ground. Programs instituted during the last 5 years at the state level and supported by the U.S. Department of Energy's (DOE) State Energy Program initiative have placed anemometers and vanes at several levels on existing tall (70 m+) communication towers. The Central Plains has a fairly high concentration of tall tower sites. The distribution of tall tower sites varies among the states in the Central Plains, because the tall tower program is new and the available state and federal funding to establish tall towers is variable. Our wind resource assessment group at DOE's National Renewable Energy Laboratory (NREL) has obtained much of these necessary measurement data from both individual state sources and regional organizations. Most of the data are available to the public, though data from one tower in Colorado are proprietary. We have begun to analyze important wind climate parameters, including wind shear from the tall towers. A total of 13 tall towers were used for this study. Eleven of the towers had the highest anemometer level between 100 m and 113 m. Two towers had the highest measurement level between 70 m and 85 m above ground. The distribution of the towers among the states is: two sites in Texas and Oklahoma; six sites in Kansas; and one site each in Colorado, South Dakota, and North Dakota. Figure 1 shows the locations and names of the thirteen towers. The wind resource at these sites can be classified as ranging from good-to-excellent. Eight tall tower sites have Class 3 resource, four sites have Class 4 resource, and one has Class 5 resource at 50 m.

THE INFRARED COLORS OF THE SUN  

Science Conference Proceedings (OSTI)

Solar infrared colors provide powerful constraints on the stellar effective temperature scale, but they must be measured with both accuracy and precision in order to do so. We fulfill this requirement by using line-depth ratios to derive in a model-independent way the infrared colors of the Sun, and we use the latter to test the zero point of the Casagrande et al. effective temperature scale, confirming its accuracy. Solar colors in the widely used Two Micron All Sky Survey (2MASS) JHK{sub s} and WISE W1-4 systems are provided: (V - J){sub Sun} = 1.198, (V - H){sub Sun} = 1.484, (V - K{sub s} ){sub Sun} = 1.560, (J - H){sub Sun} = 0.286, (J - K{sub s} ){sub Sun} = 0.362, (H - K{sub s} ){sub Sun} = 0.076, (V - W1){sub Sun} = 1.608, (V - W2){sub Sun} = 1.563, (V - W3){sub Sun} = 1.552, and (V - W4){sub Sun} = 1.604. A cross-check of the effective temperatures derived implementing 2MASS or WISE magnitudes in the infrared flux method confirms that the absolute calibration of the two systems agrees within the errors, possibly suggesting a 1% offset between the two, thus validating extant near- and mid-infrared absolute calibrations. While 2MASS magnitudes are usually well suited to derive T{sub eff}, we find that a number of bright, solar-like stars exhibit anomalous WISE colors. In most cases, this effect is spurious and can be attributed to lower-quality measurements, although for a couple of objects (3% {+-} 2% of the total sample) it might be real, and may hint at the presence of warm/hot debris disks.

Gravity Waves in the Sun  

E-Print Network (OSTI)

We present numerical simulations of penetrative convection and gravity wave excitation in the Sun. Gravity waves are self-consistently generated by a convective zone overlying a radiative interior. We produce power spectra for gravity waves in the radiative region as well as estimates for the energy flux of gravity waves below the convection zone. We calculate a peak energy flux in waves below the convection zone to be three orders of magnitude smaller than previous estimates for m=1. The simulations show that the linear dispersion relation is a good approximation only deep below the convective-radiative boundary. Both low frequency propagating gravity waves as well as higher frequency standing modes are generated; although we find that convection does not continually drive the standing g-mode frequencies.

Gravitational Lensing Characteristics of the Transparent Sun  

E-Print Network (OSTI)

The transparent Sun is modeled as a spherically symmetric and centrally condensed gravitational lens using recent Standard Solar Model (SSM) data. The Sun's minimum focal length is computed to a refined accuracy of 23.5 +/- 0.1 AU, just beyond the orbit of Uranus. The Sun creates a single image of a distant point source visible to observers inside this minimum focal length and to observers sufficiently removed from the line connecting the source through the Sun's center. Regions of space are mapped where three images of a distant point source are created, along with their associated magnifications. Solar caustics, critical curves, and Einstein rings are computed and discussed. Extremely high gravitational lens magnifications exist for observers situated so that an angularly small, unlensed source appears near a three-image caustic. Types of radiations that might undergo significant solar lens magnifications as they can traverse the core of the Sun, including neutrinos and gravitational radiation, are discussed.

Analysis of mass transfer performance in an air stripping tower  

Science Conference Proceedings (OSTI)

The carryover of working solution in a traditional stripping tower is of serious concern in real applications. A U-shaped spray tower to prevent carryover has been designed to study the stripping of water vapor from aqueous desiccant solutions of 91.8 to 95.8 wt% triethylene glycol. In this study, water vapor was removed from the diluted desiccant solution by heating the solution and stripping it with the ambient air. Therefore, the solution was concentrated to a desired concentration. This spray tower was capable of handling air flow rates from 3.2 to 5.13 kg/min and liquid flow rates from 1.6 to 2.76 kg/min. Since the literature data on air stripping towers are limited, studies on the mass transfer coefficient and other mass transfer parameters were carried out in this study. Under the operating conditions, the overall mass transfer coefficient calculated from the experimental data varied from 0.053 to 0.169 mol/m{sup 3}{center{underscore}dot}s. These corresponded to heights of a transfer unit of 2.3 to 0.71 m, respectively. The rates of stripping in this spray tower were typically varied from 2.28 to 12.15 kg H{sub 2}O/h. A correlation of the mass transfer coefficient for the air stripping process was also developed in this study.

Integrated reactor-containment hyperbolic-cooling-tower system  

Science Conference Proceedings (OSTI)

A preliminary feasibility analysis has been conducted to evaluate placing a nuclear reactor containment building inside a large hyperbolic cooling tower, a concept previously suggested for fossil-fired units but for reasons other than those that motivate this evaluation. The geometry of the design, the amount of water available, and the shielding provided by the cooling tower are beneficial to the safety characteristics of the containment under accident conditions. Three means of decay heat management are employed: an initial water spray on the containment exterior, long-term air convection on side of the containment, and creation of a water pool inside the containment. A continuously spraying water tank on top of the containment allows for a completely passive decay heat removal system. An annular air chimney around the containment is effective in long-term removal of {approximately} 1O MW (thermal) through air convection. Five percent of the water inventory in the cooling-tower pond surrounding the containment is sufficient to flood the containment interior to a depth of 14.6 ft, thereby providing an internal containment heat sink. The packing and the height of the tower provide major scrubbing and dispersing sources for any uncontrolled radioactive leak. The cooling tower veil also protects the containment from external events such as lane crashes.

Cooling Towers - Energy Conservation and Money Making Mechanisms  

E-Print Network (OSTI)

The utilization of colder water conserves energy, creates profits, increases product output. In an effort to obtain greater efficiencies and conserve both energy and dollars, all too many engineers neglect the potential of the cooling tower. Many cooling towers in operation are performing at levels as low as 50% of capability. This is energy wasteful and financially foolish. There are many reasons for this deficiency, among them the present service is greater than the original requirements, slippage due to age and deterioration, or the installation could have been originally installed undersized. This paper will investigate the various elements, their functions and methods of upgrading their performance by retrofit with the use of modern technology. Case histories will be examined in three major industries, chemicals, refrigeration and petrochemical illustrating how intelligent rebuilding can produce profits and conserve energy. Actual statistics will be cited showing that the return of investment (ROI) can be quite rapid by optimizing the performance of the cooling tower.

Conversion of Solar Two to a Kokhala hybrid power tower  

DOE Green Energy (OSTI)

The continued drop in energy prices and restructuring of the utility industry have reduced the likelihood that a follow-on commercial 100-MW, power tower project will be built immediately following the Solar Two demonstration project. Given this, it would be desirable to find a way to extend the life of the Solar Two project to allow the plant to operate as a showcase for future power tower projects. This paper looks at the possibility of converting Solar Two into a commercial Kokhala hybrid power tower plant at the end of its demonstration period in 1998. The study identifies two gas turbines that could be integrated into a Kokhala cycle at Solar Two and evaluates the design, expected performance, and economics of each of the systems. The study shows that a commercial Kokhala project at Solar Two could produce power at a cost of less than 7 e/kWhr.

Dry cooling tower operating experience in the LOFT reactor  

SciTech Connect

A dry cooling tower has been uniquely utilized to dissipate heat generated in a small experimental pressurized water nuclear reactor. Operational experience revealed that dry cooling towers can be intermittently operated with minimal wind susceptibility and water hammer occurrences by cooling potential steam sources after a reactor scram, by isolating idle tubes from the external atmosphere, and by operating at relatively high pressures.

Comparison of Second Wind Triton Data with Meteorological Tower Measurements  

DOE Green Energy (OSTI)

With the increased interest in remote sensing of wind information in recent years, it is important to determine the reliability and accuracy of new wind measurement technologies if they are to replace or supplement conventional tower-based measurements. In this study, we present the results of an analysis characterizing the measurement performance of a state-of-the-art SOund Detection And Ranging (sodar) device when compared to a high-quality tower measurement program. Second Wind Inc. (Somerville, MA, USA) provided NREL with more than six months of data from a measurement program conducted near an operating wind farm in western Texas.

Modeling, loading, and preliminary design considerations for tall guyed towers  

Science Conference Proceedings (OSTI)

In this paper, the authors first summarize the results of an investigation they carried out on the collapse of a 1900 ft tall guyed tower under ice and wind loads. Based on this investigation, they then proceed to present some structural analysis recommendations relating to loading and modeling concerns. Special emphasis is placed on the importance of ice loading, and on the level of accuracy required in modeling the nonlinear response behavior. Finally, the conclusions drawn from this study are used to formulate preliminary design guidelines. This facilitates a systematic approach for the design of tall guyed towers. 23 refs.

On Why Disks Generate Magnetic Towers and Collimate Jets  

E-Print Network (OSTI)

We show that accretion disks with magnetic fields in them ought to make jets provided that their electrical conductivity prevents slippage and there is an ambient pressure in their surroundings. We study equilibria of highly wound magnetic structures. General Energy theorems demonstrate that they form tall magnetic towers whose height grows with every turn at a velocity related to the circular velocity in the accretion disk. The pinch effect amplifies the magnetic pressures toward the axis of the towers whose stability is briefly considered.

2006 Is the Sun a Random Star  

E-Print Network (OSTI)

Abstract: The properties of our star may be associated with special prerequisites for life. By comparing our Sun to other stars in our galaxy, we may be able to identify such prerequisites. If our star is typical, stellar conditions appropriate for life, and life itself may be common in the Universe. On the other hand, if the Sun is atypical, conditions appropriate for life may be uncommon. Here we describe a method to quantify how typical or atypical the Sun is compared with other stars

The galactic environment of the Sun  

E-Print Network (OSTI)

The interstellar cloud surrounding the solar system regulates the galactic environment of the Sun and constrains the physical characteristics of the interplanetary medium. This paper compares interstellar dust grain properties observed within the solar system with dust properties inferred from observations of the cloud surrounding the solar system. Properties of diffuse clouds in the solar vicinity are discussed to gain insight into the properties of the diffuse cloud complex flowing past the Sun. Evidence is presented for changes in the galactic environment of the Sun within the next 10$^4$--10$^6$ years. The combined history of changes in the interstellar environment of the Sun, and solar activity cycles, will be recorded in the variability of the ratio of large- to medium-sized interstellar dust grains deposited onto geologically inert surfaces. Combining data from lunar core samples in the inner and outer solar system will assist in disentangling these two effects.

POLAR Investigation of the Sun - POLARIS  

E-Print Network (OSTI)

The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the Sun with an inclination of 75 degrees with respect to solar equator. This challenging orbit is made possible by the challenging development of solar sail propulsion. This first extended view of the high-latitude regions of the Sun will enable crucial observations not possible from the ecliptic viewpoint or from Solar Orbiter. While Solar Orbiter would give the first glimpse of the high latitude magnetic field and flows to probe the solar dynamo, it does not have sufficient viewing of the polar regions to achieve POLARIS' primary objective : determining the relation between the magnetism and dynamics of the Sun's polar regions and the solar cycle.

Solar Power Tower Design Basis Document, Revision 0  

DOE Green Energy (OSTI)

This report contains the design basis for a generic molten-salt solar power tower. A solar power tower uses a field of tracking mirrors (heliostats) that redirect sunlight on to a centrally located receiver mounted on top a tower, which absorbs the concentrated sunlight. Molten nitrate salt, pumped from a tank at ground level, absorbs the sunlight, heating it up to 565 C. The heated salt flows back to ground level into another tank where it is stored, then pumped through a steam generator to produce steam and make electricity. This report establishes a set of criteria upon which the next generation of solar power towers will be designed. The report contains detailed criteria for each of the major systems: Collector System, Receiver System, Thermal Storage System, Steam Generator System, Master Control System, and Electric Heat Tracing System. The Electric Power Generation System and Balance of Plant discussions are limited to interface requirements. This design basis builds on the extensive experience gained from the Solar Two project and includes potential design innovations that will improve reliability and lower technical risk. This design basis document is a living document and contains several areas that require trade-studies and design analysis to fully complete the design basis. Project- and site-specific conditions and requirements will also resolve open To Be Determined issues.

The Sun in Time: Activity and Environment  

E-Print Network (OSTI)

(abridged) The Sun's magnetic activity has steadily declined during its main-sequence life. While the solar photospheric luminosity was about 30% lower 4.6 Gyr ago when the Sun arrived on the main sequence compared to present-day levels, its faster rotation generated enhanced magnetic activity; magnetic heating processes in the chromosphere, the transition region, and the corona induced ultraviolet, extreme-ultraviolet, and X-ray emission about 10, 100, and 1000 times, respectively, the present-day levels, as inferred from young solar-analog stars. Also, the production rate of accelerated, high-energy particles was orders of magnitude higher than in present-day solar flares, and a much stronger wind escaped from the Sun, permeating the entire solar system. The consequences of the enhanced radiation and particle fluxes from the young Sun were potentially severe for the evolution of solar-system planets and moons. Interactions of high-energy radiation and the solar wind with upper planetary atmospheres may have led to the escape of important amounts of atmospheric constituents. The present dry atmosphere of Venus and the thin atmosphere of Mars may be a product of early irradiation and heating by solar high-energy radiation. High levels of magnetic activity are also inferred for the pre-main sequence Sun. At those stages, interactions of high-energy radiation and particles with the circumsolar disk in which planets eventually formed were important. Traces left in meteorites by energetic particles and anomalous isotopic abundance ratios in meteoritic inclusions may provide evidence for a highly active pre-main sequence Sun. The present article reviews these various issues related to the magnetic activity of the young Sun and the consequent interactions with its environment.

Theoretical analysis of natural-convection towers for solar-energy conversion  

DOE Green Energy (OSTI)

A theoretical study of solar-powered natural convection tower (chimney) performance is presented. Both heated and cooled towers are analyzed, the latter using evaporating water as the cooling mechanism. The results, which are applicable to any open-cycle configuration, show that the ideal conversion efficiencies of both heated and cooled natural convection towers are linear functions of height. The performance of a heated tower in an adiabatic atmospheric ideally approaches the Carnot efficiency limit of approx. 3.4%/km(1.0%/1000 ft). Including water pumping requirements, the ideal limit to cooled tower performance is approx. 2.75%/km(0.85%/1000 ft). Ambient atmospheric conditions such as vertical temperature gradient (lapse rate) and relative humidity can have significantly adverse effects on natural convection tower performance. The combined effects of lapse rate and ambient relative humidity are especially important for cooled natural convection towers.

Computer Simulation of Cooling Effect of Wind Tower on Passively Ventilated Building  

E-Print Network (OSTI)

Traditional buildings are cooled and ventilated by mechanically induced drafts. Natural ventilation aspires to cool and ventilate a building by natural means, such as cross ventilation or wind towers, without mechanical equipment. A simple computer program was developed to simulate airflow through a wind tower based on tower dimensions and air temperature. The program was compared to experimental results with reasonable agreement. Parametric analysis indicates that interior air temperature approaches outdoor air temperature asymptotically as tower height and cross-sectional area are increased, and that it may be more cost effective to increase the tower?s height than its cross sectional area. The program was then used to simulate hour-by-hour indoor air temperatures of an occupied auditorium in Dayton, OH. The results indicate that a large wind tower was able to keep the temperature of an occupied auditorium at a comfortable level year round.

The place of the Sun among the Sun-like stars  

E-Print Network (OSTI)

Context. Monitoring of the photometric and chromospheric HK emission data series of stars similar to the Sun in age and average activity level showed that there is an empirical correlation between the average stellar chromospheric activity level and the photometric variability. In general, more active stars show larger photometric variability. Interestingly, the measurements and reconstructions of the solar irradiance show that the Sun is significantly less variable than indicated by the empirical relationship. Aims. We aim to identify possible reasons for the Sun to be currently outside of this relationship. Methods. We employed different scenarios of solar HK emission and irradiance variability and compared them with available time series of Sun-like stars. Results. We show that the position of the Sun on the diagram of photometric variability versus chromospheric activity changes with time. The present solar position is different from its temporal mean position as the satellite era of continuous solar irra...

No Chemical, Zero Bleed Cooling Tower Water Treatment Process  

E-Print Network (OSTI)

This paper describes a process to treat cooling tower water by means of a fully automated and chemical free mechanical water treatment process. This is an alternative to conventional chemical treatment. Beginning with a suction pump to draw water out of the tower sump, water goes through a permanent magnetic descaler to increase the water solubility and begin the scale inhibition process. This also descales existing scale build-up in the system. Ozone is manufactured from ambient air and injected into the bypass system through a venturi type injector. This kills algae, slime and bacteria and enhances the magnetic descaling process. The final stage filter separates solids from the water to prevent corrosion from impingement. These solids are automatically purged to the sanitary drain. Clarified water is returned to the sump where the process repeats on a 10%-20% by volume side stream basis.

CFD MODELING ANALYSIS OF MECHANICAL DRAFT COOLING TOWER  

Science Conference Proceedings (OSTI)

Industrial processes use mechanical draft cooling towers (MDCT's) to dissipate waste heat by transferring heat from water to air via evaporative cooling, which causes air humidification. The Savannah River Site (SRS) has a MDCT consisting of four independent compartments called cells. Each cell has its own fan to help maximize heat transfer between ambient air and circulated water. The primary objective of the work is to conduct a parametric study for cooling tower performance under different fan speeds and ambient air conditions. The Savannah River National Laboratory (SRNL) developed a computational fluid dynamics (CFD) model to achieve the objective. The model uses three-dimensional steady-state momentum, continuity equations, air-vapor species balance equation, and two-equation turbulence as the basic governing equations. It was assumed that vapor phase is always transported by the continuous air phase with no slip velocity. In this case, water droplet component was considered as discrete phase for the interfacial heat and mass transfer via Lagrangian approach. Thus, the air-vapor mixture model with discrete water droplet phase is used for the analysis. A series of the modeling calculations was performed to investigate the impact of ambient and operating conditions on the thermal performance of the cooling tower when fans were operating and when they were turned off. The model was benchmarked against the literature data and the SRS test results for key parameters such as air temperature and humidity at the tower exit and water temperature for given ambient conditions. Detailed results will be presented here.

High Flux Isotopes Reactor (HFIR) Cooling Towers Demolition Waste Management  

SciTech Connect

This paper describes the results of a joint initiative between Oak Ridge National Laboratory, operated by UT-Battelle, and Bechtel Jacobs Company, LLC (BJC) to characterize, package, transport, treat, and dispose of demolition waste from the High Flux Isotope Reactor (HFIR), Cooling Tower. The demolition and removal of waste from the site was the first critical step in the planned HFIR beryllium reflector replacement outage scheduled. The outage was scheduled to last a maximum of six months. Demolition and removal of the waste was critical because a new tower was to be constructed over the old concrete water basin. A detailed sampling and analysis plan was developed to characterize the hazardous and radiological constituents of the components of the Cooling Tower. Analyses were performed for Resource Conservation and Recovery Act (RCRA) heavy metals and semi-volatile constituents as defined by 40 CFR 261 and radiological parameters including gross alpha, gross beta, gross gamma, alpha-emitting isotopes and beta-emitting isotopes. Analysis of metals and semi-volatile constituents indicated no exceedances of regulatory limits. Analysis of radionuclides identified uranium and thorium and associated daughters. In addition 60Co, 99Tc, 226Rm, and 228Rm were identified. Most of the tower materials were determined to be low level radioactive waste. A small quantity was determined not to be radioactive, or could be decontaminated. The tower was dismantled October 2000 to January 2001 using a detailed step-by-step process to aid waste segregation and container loading. The volume of waste as packaged for treatment was approximately 1982 cubic meters (70,000 cubic feet). This volume was comprised of plastic ({approx}47%), wood ({approx}38%) and asbestos transite ({approx}14%). The remaining {approx}1% consisted of the fire protection piping (contaminated with lead-based paint) and incidental metal from conduit, nails and braces/supports, and sludge from the basin. The waste, except for the asbestos, was volume reduced via a private contract mechanism established by BJC. After volume reduction, the waste was packaged for rail shipment. This large waste management project successfully met cost and schedule goals.

The Sun and Climate Solar Irradiance  

E-Print Network (OSTI)

The Sun and Climate #12;Solar Irradiance The Solar Constant f = 1.4 x 106 erg/cm2/s. Over the surface of the Earth, this is 2 x 1024 erg/s, or 2 x 1017 watts (100 million gigawatts). This energy input keeps the Earth warm. If the solar constant were To change, so would the Earth's temperature. Solar

Electrochromic sun control coverings for windows  

DOE Green Energy (OSTI)

The 2 billion square meters (m{sup 2}) of building windows in the United States cause a national energy drain almost as large as the energy supply of the Alaskan oil pipeline. Unlike the pipeline, the drain of energy through windows will continue well into the 21st century. A part of this energy drain is due to unwanted sun gain through windows. This is a problem throughout the country in commercial buildings because they generally require air conditioning even in cold climates. New commercial windows create an additional 1600 MW demand for peak electric power in the United States each year. Sun control films, widely used in new windows and as retrofits to old windows, help to mitigate this problem. However, conventional, static solar control films also block sunlight when it is wanted for warmth and daylighting. New electrochromic, switchable, sun-gain-control films now under development will provide more nearly optimal and automatic sun control for added comfort, decreased building operating expense, and greater energy saving. Switchable, electrochromic films can be deposited on polymers at high speeds by plasma enhanced chemical vapor deposition (PECVD) in a process that may be suitable for roll coating. This paper describes the electrochromic coatings and the PECVD processes, and speculates about their adaptability to high-speed roll coating. 8 refs., 3 figs.

Hybrid Tower Study: Volume 3: Phase 3 -- Scale Model Development and Full-Scale Tests  

Science Conference Proceedings (OSTI)

Hybrid towers maximize the power transmission efficiency of the available space whenever there is the need to have both ac and dc lines in the same corridor. This study developed calculation techniques and design rules for the placement of conductors energized with HVAC and HVDC circuits on the same towers. Significantly, the study did not identify any hybrid interactions that would prevent the successful operation of a hybrid corridor or hybrid tower transmission line.

Lower Cost CPV 3-Sun Mirror Modules  

SciTech Connect

In a series of patent applications filed between 2002 and 2005, JX Crystals Inc described a evolutionary lower-cost low-concentration planar solar photovoltaic module that uses multiple linear rows of silicon cells and standard one-sun circuit laminations incorporating glass and EVA weather proofing encapsulations. The three novel features that we described are interdependent and integrated together to yield lower cost PV modules. These 3 novel features are: (1) The use of rows of linear mirrors or linear Fresnel lenses aligned with the cell rows and concentrating the sunlight onto the cell rows. (2) The addition of a thin aluminum sheet heat spreader on the back of the circuit lamination to spread the heat away from the cell rows so that the cell operating temperature remains acceptably low. (3) The incorporation of slots in the back of the aluminum sheet heat spreader to accommodate the differences in thermal expansion between the silicon cells, the glass, and the aluminum so that the circuit interconnectivity is maintained over time. Various embodiments of this planar linear concentrator panel are shown in figures 1 to 5. Figures 1 and 2 show the original planar linear concentrator module concept from July of 2002 with either mirrors (figure 1) or linear Fresnel lenses (figure 2). The idea was expanded in 2003 with the idea of an aluminum sheet heat spreader added to the back of a standard PV circuit lamination as shown in figure 3. In 2003, we also transitioned from half cells to third cells using SunPower cells as shown in figure 4. JX Crystals Inc then received funding for the 3-sun PV mirror module concept from the Shanghai Science and Technology Commission in 2003 and from the Shanghai Flower Port and the Shanghai Import and Export Trading Company in 2005. This funding led to a 800 panel pilot production run of our JX Crystals designed 3-sun module in 2006. 672 of these panels were installed in a 100 kW demonstration and an additional 24 panels were installed in a second 4 kW demonstration both at the Flower Port in Shanghai. Both of these systems were completed in 2006. Our 3-sun PV Panel concept has been described previously (see references 1, 2, & 3 available at www.jxcrystals.com under publication tab). We are now interested in bringing this potentially lower cost 3-sun technology back to the US. For any new technology, three issues need to be addressed. They are performance, durability, and cost. These topics are addressed in the next 3 sections.

Putting the sun to work in Sacramento  

SciTech Connect

At dawn this morning, the sun went to work for customers of the Sacramento Municipal Utility District (SMUD). The largest photovoltaic (PV) power plant in the world, adjacent to the closed nuclear power plant at Rancho Seco, generated enough electricity for over a thousand customers, rooftop solar water heaters lowered thousands of residential electric bills and rooftop PV systems turned hundreds of Sacramento homes into mini power plants. SMUD, in partnership with their customers-owners, is leading the way in putting the sun to work today. SMUD plans to have at least half of its energy come from energy efficiency, existing hydroelectric plants and renewable resources in this decade. SMUD expects investments made in solar power today to provide its customer-owners with substantial long-term energy, environmental and community benefits. This article describes some of SMUD's efforts.

Properties of Near-Sun Asteroids  

E-Print Network (OSTI)

Asteroids near the Sun can attain equilibrium temperatures sufficient to induce surface modification from thermal fracture, desiccation and decomposition of hydrated silicates. We present optical observations of nine asteroids with perihelia solar temperatures greater than/equal to 800 K) taken to search for evidence of thermal modification. We find that the broadband colors of these objects are diverse but statistically indistinguishable from those of planet-crossing asteroids having perihelia near 1 AU. Furthermore, images of these bodies taken away from perihelion show no evidence for on-going mass-loss (model-dependent limits roughly less than/equal to 1 kg /s) that might result from thermal disintegration of the surface. We conclude that, while thermal modification may be an important process in the decay of near-Sun asteroids and in the production of debris, our new data provide no evidence for it.

Solar neutrinos: Probing the sun or neutrinos  

SciTech Connect

The decade of the 1990's should prove to be a landmark period for the study of solar neutrino physics. Current observations show 2-3 times fewer neutrinos coming from the sun than are theoretically expected. As we enter the decade, new experiments are poised to attempt and discover whether this deficit is a problem with our understanding of how the sun works, is a hint of new neutrino properties beyond those predicted by the standard model of particle physics, or perhaps a combination of both. This paper will review the current status of the field and point out how future measurements should help solve this interesting puzzle. 11 refs., 3 figs., 1 tab.

The Sun's Interior Metallicity Constrained by Neutrinos  

E-Print Network (OSTI)

Observed solar neutrino fluxes are employed to constrain the interior composition of the Sun. Including the effects of neutrino flavor mixing, the results from Homestake, Sudbury, and Gallium experiments constrain the Mg, Si, and Fe abundances in the solar interior to be within a factor 0.89 to 1.34 of the surface values with 68% confidence. If the O and/or Ne abundances are increased in the interior to resolve helioseismic discrepancies with recent standard solar models, then the nominal interior Mg, Si, and Fe abundances are constrained to a range of 0.83 to 1.24 relative to the surface. Additional research is needed to determine whether the Sun's interior is metal poor relative to its surface.

The Daemon Kernel of the Sun  

E-Print Network (OSTI)

The daemon-stimulated proton decay is capable of providing an appreciable part of the Sun luminosity as well as nonelectron flavor component in the solar neutrino flux. This follows (1) from our experiments on detection of negative daemons in Earth-crossing orbits, which give ~1 microsec for the decay time of a daemon-containing proton, and (2) from an estimate of the total number of daemons which could be captured by the Sun from the Galactic disk (up to \\~2.4E30). Because of their huge mass (~3E-5 g), the captured daemons form in the Sun's center a kernel a few cm in size. The protons diffuse into the kernel to decay there with a release of energy. Physically sound estimates of the parameters of the kernel can be obtained if it consists mainly of negative daemons. Proton decay maintains a high temperature of the daemon gas (up to \\~1E11-1E12 K), which makes it physically collisionless and prevents kernel collapse into a black hole.

A Regenerative High-Rise Tower in Shreveport, Louisiana  

E-Print Network (OSTI)

Zero Net Energy Buildings are increasingly being designed and constructed in response to the demand for sustainable buildings. But, we must now go beyond merely sustaining our environment for future generations we must provide regenerative designs that restore our natural environment. This paper will document the design of a regenerative high-rise tower in Shreveport, Louisiana, which will serve as a facility to train individuals in a non-profit organizations renewal strategies and demonstrate by example the pedagogy of regenerative design. The 16-story structure built in the 1950s and named the Petroleum Tower, reflecting the commodity that then ruled the local economy was vacant and asbestos-laden when given to the non-profit Community Renewal International (CRI) in 2001. In 2006, funded by a grant from the U.S. Environmental Protection Agency, workers removed the asbestos. Through a follow up grant from the U.S. Department of Energy to support the design process of a new CRI headquarters building, the University of Texas at Austin School of Architecture completed architectural design studies for the building renewal. The principles of this new design include: day lighting, envelope configuration, building integrated photovoltaic systems, green surfaces, ventilation strategies, advanced mechanical cooling systems, regenerative elevator systems, energy management systems, water harvesting, grey water systems, trigeneration systems and a combined heating, hot water and power biodiesel plant.

FLUX MEASUREMENTS FROM A TALL TOWER IN A COMPLEX LANDSCAPE  

Science Conference Proceedings (OSTI)

The accuracy and representativeness of flux measurements from a tall tower in a complex landscape was assessed by examining the vertical and sector variability of the ratio of wind speed to momentum flux and the ratio of vertical advective to eddy flux of heat. The 30-60 m ratios were consistent with theoretical predictions which indicate well mixed flux footprints. Some variation with sector was observed that were consistent with upstream roughness. Vertical advection was negligible compared with vertical flux except for a few sectors at night. This implies minor influence from internal boundary layers. Flux accuracy is a function of sector and stability but 30-60 m fluxes were found to be generally representative of the surrounding landscape. This paper will study flux data from a 300 m tower, with 4 levels of instruments, in a complex landscape. The surrounding landscape will be characterized in terms of the variation in the ratio of mean wind speed to momentum flux as a function of height and wind direction. The importance of local advection will be assessed by comparing vertical advection with eddy fluxes for momentum and heat.

ON THE STRUCTURE AND STABILITY OF MAGNETIC TOWER JETS  

SciTech Connect

Modern theoretical models of astrophysical jets combine accretion, rotation, and magnetic fields to launch and collimate supersonic flows from a central source. Near the source, magnetic field strengths must be large enough to collimate the jet requiring that the Poynting flux exceeds the kinetic energy flux. The extent to which the Poynting flux dominates kinetic energy flux at large distances from the engine distinguishes two classes of models. In magneto-centrifugal launch models, magnetic fields dominate only at scales {approx}< 100 engine radii, after which the jets become hydrodynamically dominated (HD). By contrast, in Poynting flux dominated (PFD) magnetic tower models, the field dominates even out to much larger scales. To compare the large distance propagation differences of these two paradigms, we perform three-dimensional ideal magnetohydrodynamic adaptive mesh refinement simulations of both HD and PFD stellar jets formed via the same energy flux. We also compare how thermal energy losses and rotation of the jet base affects the stability in these jets. For the conditions described, we show that PFD and HD exhibit observationally distinguishable features: PFD jets are lighter, slower, and less stable than HD jets. Unlike HD jets, PFD jets develop current-driven instabilities that are exacerbated as cooling and rotation increase, resulting in jets that are clumpier than those in the HD limit. Our PFD jet simulations also resemble the magnetic towers that have been recently created in laboratory astrophysical jet experiments.

Coagulation chemistries for silica removal from cooling tower water.  

SciTech Connect

The formation of silica scale is a problem for thermoelectric power generating facilities, and this study investigated the potential for removal of silica by means of chemical coagulation from source water before it is subjected to mineral concentration in cooling towers. In Phase I, a screening of many typical as well as novel coagulants was carried out using concentrated cooling tower water, with and without flocculation aids, at concentrations typical for water purification with limited results. In Phase II, it was decided that treatment of source or make up water was more appropriate, and that higher dosing with coagulants delivered promising results. In fact, the less exotic coagulants proved to be more efficacious for reasons not yet fully determined. Some analysis was made of the molecular nature of the precipitated floc, which may aid in process improvements. In Phase III, more detailed study of process conditions for aluminum chloride coagulation was undertaken. Lime-soda water softening and the precipitation of magnesium hydroxide were shown to be too limited in terms of effectiveness, speed, and energy consumption to be considered further for the present application. In Phase IV, sodium aluminate emerged as an effective coagulant for silica, and the most attractive of those tested to date because of its availability, ease of use, and low requirement for additional chemicals. Some process optimization was performed for coagulant concentration and operational pH. It is concluded that silica coagulation with simple aluminum-based agents is effective, simple, and compatible with other industrial processes.

Method and system for simulating heat and mass transfer in cooling towers  

DOE Patents (OSTI)

The present invention is a system and method for simulating the performance of a cooling tower. More precisely, the simulator of the present invention predicts values related to the heat and mass transfer from a liquid (e.g., water) to a gas (e.g., air) when provided with input data related to a cooling tower design. In particular, the simulator accepts input data regarding: (a) cooling tower site environmental characteristics; (b) cooling tower operational characteristics; and (c) geometric characteristics of the packing used to increase the surface area within the cooling tower upon which the heat and mass transfer interactions occur. In providing such performance predictions, the simulator performs computations related to the physics of heat and mass transfer within the packing. Thus, instead of relying solely on trial and error wherein various packing geometries are tested during construction of the cooling tower, the packing geometries for a proposed cooling tower can be simulated for use in selecting a desired packing geometry for the cooling tower.

Performance of 3-Sun Mirror Modules on Sun Tracking Carousels on Flat Roof Buildings  

Science Conference Proceedings (OSTI)

Commercial buildings represent a near term market for cost competitive solar electric power provided installation costs and solar photovoltaic module costs can be reduced. JX Crystals has developed a carousel sun tracker that is prefabricated and can easily be deployed on building flat roof tops without roof penetration. JX Crystals is also developing 3-sun PV mirror modules where less expensive mirrors are substituted for two-thirds of the expensive single crystal silicon solar cell surface area. Carousels each with four 3-sun modules have been set up at two sites, specifically at Oak Ridge National Lab and at the University of Nevada in Las Vegas. The test results for these systems are presented.

Carousel Trackers with 1-Sun or 3-Sun Modules for Commercial Building Rooftops  

Science Conference Proceedings (OSTI)

The goal is lower cost solar electricity. Herein, two evolutional steps are described toward achieving this goal. The first step is to follow the sun with a solar tracker. Herein, a carousel tracker is described for mounting on commercial building flat rooftops in order to produce more kWh per kW relative to fixed PV modules. The second evolutionary improvement is to produce lower cost 3-sun CPV modules where two thirds of the expensive single crystal silicon material is replaced by less expensive mirror material. This paper describes the performance and durability of two prototype installations demonstrating these evolutionary innovations. In the first case, the installation and operation of 2 carousels equipped with traditional flat plate modules is described. In the second case, the operation of a carousel equipped with new 3-sun CPV modules is described. Both systems have been operating as expected for several months through the winter of 2007.

Verification of BModes: Rotary Beam and Tower Modal Analysis Code; Preprint  

DOE Green Energy (OSTI)

This paper describes verification of BModes, a finite-element code developed to provide coupled modes for the blades and tower of a wind turbine. The blades, which may be rotating or non-rotating, and the towers, whether onshore or offshore, are modeled using specialized 15-dof beam finite elements. Both blade and tower models allow a tip attachment, which is assumed to be rigid body with six moments of inertia, and a mass centroid that may be offset from the blade or tower axis. Examples of tip attachments are aerodynamic brakes for blades and nacelle-rotor subassembly for towers. BModes modeling allows for tower supports including tension wires, floating platforms, and monopiles on elastic foundations. Coupled modes (implying coupling of flap, lag, axial, and torsional motions) are required for modeling major flexible components in a modal-based, aeroelastic code such as FAST1. These are also required for validation of turbine models using experimental data, modal-based fatigue analysis, controls design, and understanding aeroelastic-stability behavior of turbines. Verification studies began with uniform tower models, with and without tip inertia, and progressed to realistic towers. For the floating turbine, we accounted for the effects of hydrodynamic inertia, hydrostatic restoring, and mooring lines stiffness. For the monopole-supported tower, we accounted for distributed hydrodynamic mass on the submerged part of the tower and for distributed foundation stiffness. Finally, we verified a model of a blade carrying tip mass and rotating at different speeds (verifications of other blade models, rotating or non-rotating, have been reported in another paper.) Verifications were performed by comparing BModes-generated modes with analytical results, if available, or with MSC.ADAMS results. All results in general show excellent agreement.

Search for Neutrinos from the Sun  

DOE R&D Accomplishments (OSTI)

A solar neutrino detection system has been built to observe the neutrino radiation from the sun. The detector uses 3,900,000 liters of tetrachloroethylene as the neutrino capturing medium. Argon is removed from the liquid by sweeping with helium gas, and counted in a small low level proportional counter. The recovery efficiency of the system was tested with Ar{sup 36} by the isotope dilution method, and also with Ar{sup 37} produced in the liquid by fast neutrons. These tests demonstrate that Ar{sup 37} produced in the liquid by neutrino capture can be removed with a 95 percent efficiency by the procedure used.
