Development of analytic intermodal freight networks for use within a GIS  

SciTech Connect (OSTI)

The paper discusses the practical issues involved in constructing intermodal freight networks that can be used within GIS platforms to support inter-regional freight routing and subsequent (for example, commodity flow) analysis. The procedures described can be used to create freight-routable and traffic flowable interstate and intermodal networks using some combination of highway, rail, water and air freight transportation. Keys to realistic freight routing are the identification of intermodal transfer locations and associated terminal functions, a proper handling of carrier-owned and operated sub-networks within each of the primary modes of transport, and the ability to model the types of carrier services being offered.

Suborbital freight delivery concept exploration  

SciTech Connect (OSTI)

Suborbital Freight, sometimes called Fast Freight, is delivery of high priority packages over intercontinental distances in periods of approximately one hour. The vehicles required are usually rocket-powered and have total ideal velocities of around 7.5 km/second. Analysis of this market indicates that there are niches where commercial operations are possible and might even be profitable using today{close_quote}s state-of-the-art technologies. The key requirements to capture this market are low nonrecurring costs, quick turnaround ({lt}9hours), and high reliability (0.999). This draft is a report on work in progress. The Fast Freight study will be completed before the STAIF-97 conference and results will be presented at that time. {copyright} {ital 1997 American Institute of Physics.}

Methodology for Estimating ton-Miles of Goods Movements for U.S. Freight Mulitimodal Network System  

SciTech Connect (OSTI)

Ton-miles is a commonly used measure of freight transportation output. Estimation of ton-miles in the U.S. transportation system requires freight flow data at disaggregated level (either by link flow, path flows or origin-destination flows between small geographic areas). However, the sheer magnitude of the freight data system as well as industrial confidentiality concerns in Census survey, limit the freight data which is made available to the public. Through the years, the Center for Transportation Analysis (CTA) of the Oak Ridge National Laboratory (ORNL) has been working in the development of comprehensive national and regional freight databases and network flow models. One of the main products of this effort is the Freight Analysis Framework (FAF), a public database released by the ORNL. FAF provides to the general public a multidimensional matrix of freight flows (weight and dollar value) on the U.S. transportation system between states, major metropolitan areas, and remainder of states. Recently, the CTA research team has developed a methodology to estimate ton-miles by mode of transportation between the 2007 FAF regions. This paper describes the data disaggregation methodology. The method relies on the estimation of disaggregation factors that are related to measures of production, attractiveness and average shipments distances by mode service. Production and attractiveness of counties are captured by the total employment payroll. Likely mileages for shipments between counties are calculated by using a geographic database, i.e. the CTA multimodal network system. Results of validation experiments demonstrate the validity of the method. Moreover, 2007 FAF ton-miles estimates are consistent with the major freight data programs for rail and water movements.

The Passenger Pigeon

Passenger Pigeon Passenger Pigeon Nature Bulletin No. 181-A February 27, 1965 Forest Preserve District of Cook County Seymour Simon, President Roland F. Eisenbeis, Supt. of Conservation THE PASSENGER PIGEON We Americans have been a greedy heedless people plundering and wasting the natural resources which made possible the building of this great nation -- the soils, the waters, the forests, the minerals and the wildlife, In the United States there was once an abundance of wildlife never found on any other land. We have come close to exterminating many valuable kinds, notably the buffalo and the beaver. Several species once abundant are extinct, among them the Passenger Pigeon. The passenger pigeon was a graceful elegant bird with a long wedge- shaped tail, considerably larger than our Mourning Dove and mighty good to eat. The males were handsome: slaty blue and brown above; the head blue; the sides and back of the neck iridescent with pink, purple, green and gold; the breast a rich reddish-brown shading to pinkish on the sides; with short stout red legs. Unlike other doves and pigeons, its voice was rather loud and harsh. The females were more drab in color. Native to the unbroken forests which covered most of central and eastern North America, they nested in huge colonies. An area of 100 square miles might have every tree loaded with nests, some times 100 nests in a single tree. The nests were merely a crisscross jumble of sticks in which one pure-white egg was laid.

Freight Shuttle System: Cross-Border Movement of Goods  

SciTech Connect (OSTI)

The Freight Shuttle System (FSS) is designed to provide freight transportation services between those short and intermediate distance locations (within 600 miles) that are currently handling large volumes of freight traffic. Much like trucks, the FSS's transporters are autonomous: each transporter has its own propulsion and travels independently of other transporters. Inspired by railroads, each FSS transporter has steel wheels operating on a steel running surface and can carry either a standardsize freight container or an over-the-road truck trailer. However, unlike either rail or trucks, the FSS runs on an elevated, dedicated guideway to avoid the interference of other transportation systems. The objective of this report is to examine the potential viability for an alternative transportation system for trailers and containers in a multi-national, cross-border setting. The El Paso-Ciudad Juarez region serves as the environment of this analysis.

Transportation Energy Futures Series: Freight Transportation Demand: Energy-Efficient Scenarios for a Low-Carbon Future  

SciTech Connect (OSTI)

Freight transportation demand is projected to grow to 27.5 billion tons in 2040, and to nearly 30.2 billion tons in 2050. This report describes the current and future demand for freight transportation in terms of tons and ton-miles of commodities moved by truck, rail, water, pipeline, and air freight carriers. It outlines the economic, logistics, transportation, and policy and regulatory factors that shape freight demand, the trends and 2050 outlook for these factors, and their anticipated effect on freight demand. After describing federal policy actions that could influence future freight demand, the report then summarizes the capabilities of available analytical models for forecasting freight demand. This is one in a series of reports produced as a result of the Transportation Energy Futures project, a Department of Energy-sponsored multi-agency effort to pinpoint underexplored strategies for reducing GHGs and petroleum dependence related to transportation.

Measurement of energy-saving effect by intermodal freight transport in Thailand  

Science Journals Connector (OSTI)

In Thailand, transport sector is the largest energy consuming sector (38%). Road haulage of freight transport accounts for approximately 92% of total domestic freight movements. Accordingly, it is one of the largest contributors to adverse environmental impacts. This study presents one option to reduce energy consumption through modal shift from trailer to intermodal transport involving railway and waterway. It focuses on freight movements between Bangkok and Hat Yai in Thailand. Energy savings are measured by multi-objective optimisation model using decision variables consisting of three mode options: trailer only, intermodal-rail and intermodal-waterway. In addition to energy consumption, the objective function also includes time and charge of shipment factor.

Localisation of freight consolidation centres serving small road hauliers in a wider urban area: barriers for more efficient freight deliveries in Gothenburg  

Science Journals Connector (OSTI)

Abstract This paper discusses the negative impacts of freight transport growth, especially in and around urban areas. Over time, a growing number of road freight vehicles have delivered less freight over longer distances, while average load factors have been reduced. This development is unsatisfactory, as transport capacity that could have been used more efficiently is lost. To mitigate negative impact, it has been suggested that freight consolidation and better planned localisation of freight consolidation centres (FCCs) would improve city logistics. Based on primary data, this paper investigates the potential to establish urban \\{FCCs\\} intended for small road hauliers (SRHs) delivering goods to the retail sector in a wider geographical area, the Gothenburg region in Sweden. While the findings show that a large majority of \\{SRHs\\} could reach potential FCC locations in a short time, congestion affects deliveries and several factors, many of which were observed already in the 1970s, restrict FCC establishments. Under present conditions, there is little scope for \\{SRHs\\} to successfully deliver goods to retailers in the Gothenburg region from FCCs; therefore, a more efficient urban transport system from a business or societal perspective is unlikely. Policy makers need to take into consideration the different segments, requirements, and characteristics of different cities before venturing into costly FCC projects.

Exhaust emissions from two intercity passenger locomotives  

SciTech Connect (OSTI)

To enhance the effectiveness of intercity passenger rail service in mitigating exhaust emissions in California, the California Department of Transportation (Caltrans) included limits on exhaust emissions in its intercity locomotive procurement specifications. Because there were no available exhaust emission test data on which emission reduction goals could be based, Caltrans funded a test program to acquire gaseous and particulate exhaust emissions data, along with smoke opacity data, from two state-of-the-art intercity passenger locomotives. The two passenger locomotives (an EMD F59PH and a GE DASH8-32BWH) were tested at the Association of American Railroads Chicago Technical Center. The EMD locomotive was equipped with a separate Detroit Diesel Corporation (DDC) 8V-149 diesel engine used to provide 480 V AC power for the trailing passenger cars. This DDC engine was also emission tested. These data were used to quantify baseline exhaust emission levels as a challenge to locomotive manufacturers to offer new locomotives with reduced emissions. Data from the two locomotive engines were recorded at standard fuel injection timing and with the fuel injection timing retarded 4 deg in an effort to reduce NO[sub x] emissions. Results of this emissions testing were incorporated into the Caltrans locomotive procurement process by including emission performance requirements in the Caltrans intercity passenger locomotive specification, and therefore in the procurement decision. This paper contains steady-state exhaust emission test results for hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NO[sub x]), and particulate matter (PM) from the two locomotives. Computed sulfur dioxide (SO[sub 2]) emissions are also given, and are based on diesel fuel consumption and sulfur content. Exhaust smoke opacity is also reported.

The enablers and inhibitors of intermodal rail freight between Asia and Europe  

Science Journals Connector (OSTI)

Abstract Contemporary modes in intercontinental transportation are sea and air freight. The geographical connection of Eurasia additionally enables rail freight via the Eurasian landbridge. This transport concept reduces lead time compared to sea freight at lower cost than air or sea-air freight and hence fits into a strategic niche between established modes. These characteristics facilitate developments in supply chain management like increasing transport distances and continuous cost reduction together with relatively new trends (smaller, but more frequent shipments, flexibility and sustainability) that are only partly satisfied by contemporary modes. At this moment, the Eurasian landbridge is at an immature state, used by few shippers. This paper intends to identify factors that enable, respectively, inhibit Eurasian rail freight and understand how inhibitors can be overcome. The research based on case studies reviewing literature and conducting interviews to investigate individual landbridge routes. Besides providing secondary data, literature identified stakeholders and thus served as input for 24 semi-structured interviews to gather primary data. Both data streams were then combined to reveal the current attractiveness of Eurasian rail freight. A future outlook in the closing section aims at stimulating further research and thinking in order to create a viable alternative for global supply chain management.

Location of Freight Consolidation Centres Serving the City and Its Surroundings  

Science Journals Connector (OSTI)

This paper investigates small road haulier's spatial location and road network accessibility in relation to proposed freight consolidation centres (FCCs). For many decades, the overall load factor in freight vehicles has decreased; smaller volumes of goods have been transported over longer distances. To counteract this, a well-planned localisation of \\{FCCs\\} has been suggested as a measure to improve transport efficiency. Based on 3,024 road hauliers, road haulier associations, freight forwarders, and delivery firms/couriers located in the Western part of Sweden, the analysis show a high concentration of small road hauliers towards the largest city, its immediate surroundings, and towards existing facilities of large freight forwarders and road haulier associations. Furthermore, the accessibility analysis shows that a very large majority of the small road hauliers as well as large forwarders and haulier associations are reached within a short time distance from the proposed FCCs, indicating the potential to establish \\{FCCs\\} serving small road hauliers. While it is not possible to conclude that the proposed \\{FCCs\\} are optimally located, the paper provides a basis to further investigate the most appropriate locations of \\{FCCs\\} serving the city and its surroundings, and whether and under what conditions FCC establishments are viable.

Emissions Control Failures in Passenger Cars

5 5 Emissions Control Failures in Passenger Cars Two measures of car model malfunction probability, fraction of cars over 1% CO (y-axis) and average CO concentration of all cars (x-axis), demonstrate that five 1987-89 car models (14 year-model combinations) have a malfunction probability several times that of all other models. When an automobile's emissions control system fails, it may be because that model is more prone to failure than others, according to a study conducted by the Center's Energy Analysis Program and Marc Ross of the University of Michigan. This finding goes against the conventional wisdom that improper maintenance or deliberate disabling of the emissions systems by car owners is the cause of "high-emitting" vehicles. The results may provide clean-air

An empirical study of direct rebound effect for road freight transport in China  

Science Journals Connector (OSTI)

Abstract Improving energy efficiency has been considered as a major approach to reduce transportation fuel consumption, whereas its effectiveness that reduced transportation cost may lead to incremental energy use-i.e., a direct rebound effect. This paper provides a critical review of direct rebound effect literature, adopts a double logarithmic regression equation and a error correction model respectively to measure the magnitude of long-term and short-term direct rebound effects by 31 provincial panel data of China from 1999 to 2011. The empirical study shows that: in aspect of long term, a partial rebound effect exist in Chinese road freight transportation department, and its magnitude of entire nation, eastern, central and western regions are 84%, 52%, 80% and 78%. A majority of the expected energy reduction from efficiency improvement could be offset due to the existence of rebound effect; independent policy of improving energy efficiency is not as effective as people expected. In aspect of short term, a tiny super conservation effect exists in Chinese road freight transportation department. Further investigation indicated that direct rebound effect for road freight transportation tends to decline as growth rate of urbanization decrease.

Transportation Energy Futures Series: Freight Transportation Modal Shares: Scenarios for a Low-Carbon Future  

SciTech Connect (OSTI)

Truck, rail, water, air, and pipeline modes each serve a distinct share of the freight transportation market. The current allocation of freight by mode is the product of technologic, economic, and regulatory frameworks, and a variety of factors -- price, speed, reliability, accessibility, visibility, security, and safety -- influence mode. Based on a comprehensive literature review, this report considers how analytical methods can be used to project future modal shares and offers insights on federal policy decisions with the potential to prompt shifts to energy-efficient, low-emission modes. There are substantial opportunities to reduce the energy used for freight transportation, but it will be difficult to shift large volumes from one mode to another without imposing considerable additional costs on businesses and consumers. This report explores federal government actions that could help trigger the shifts in modal shares needed to reduce energy consumption and emissions. This is one in a series of reports produced as a result of the Transportation Energy Futures project, a Department of Energy-sponsored multi-agency effort to pinpoint underexplored strategies for reducing GHGs and petroleum dependence related to transportation.

Effect of a sudden fuel shortage on freight transport in the United States: an overview  

SciTech Connect (OSTI)

A survey was made of the potential effects of a sudden reduction of fuel supplies on freight transport via truck, rail, water, and pipeline. After a brief discussion of the energy characteristics of each of these modes of transport, short-term strategies for making better use of fuel in a crisis are investigated. Short-term is taken to mean something on the order of six months, and a crisis is taken to be the result of something on the order of a 20% drop in available fuel. Although no succinct or well-established conclusions are drawn, the gist of the paper is that the potential for short-term conservation, without a serious disruption of service, exists but does not appear to be large. It is remarked that it is possible, through further study, to obtain a fairly accurate reckoning of the physical ability of the freight transport network to weather a fuel crisis, but that it is impossible to say in advance what freight carriers will in fact do with the network.

Global energy consumption due to friction in passenger cars  

Science Journals Connector (OSTI)

This study presents calculations on the global fuel energy consumption used to overcome friction in passenger cars in terms of friction in the engine, transmission, tires, and brakes. Friction in tribocontacts was estimated according to prevailing contact mechanisms such as elastohydrodynamic, hydrodynamic, mixed, and boundary lubrication. Coefficients of friction in the tribocontacts were estimated based on available information in the literature on the average passenger car in use today, a car with todays advanced commercial tribological technology, a car with todays best advanced technology based upon recent research and development, and a car with the best technology forecasted in the next 10 years. The following conclusions were reached: In passenger cars, one-third of the fuel energy is used to overcome friction in the engine, transmission, tires, and brakes. The direct frictional losses, with braking friction excluded, are 28% of the fuel energy. In total, 21.5% of the fuel energy is used to move the car. Worldwide, 208,000 million liters of fuel (gasoline and diesel) was used in 2009 to overcome friction in passenger cars. This equals 360 million tonne oil equivalent per year (Mtoe/a) or 7.3millionTJ/a. Reductions in frictional losses will lead to a threefold improvement in fuel economy as it will reduce both the exhaust and cooling losses also at the same ratio. Globally, one passenger car uses on average of 340l of fuel per year to overcome friction, which would cost 510 euros according to the average European gas price in 2011 and corresponds to an average driving distance of 13,000km/a. By taking advantage of new technology for friction reduction in passenger cars, friction losses could be reduced by 18% in the short term (510 years) and by 61% in the long term (1525 years). This would equal worldwide economic savings of 174,000 million euros and 576,000 million euros, respectively; fuel savings of 117,000 million and 385,000 million liters, respectively; and CO2 emission reduction of 290 million and 960 million tonnes, respectively. The friction-related energy losses in an electric car are estimated to be only about half those of an internal combustion passenger car. Potential actions to reduce friction in passenger cars include the use of advanced coatings and surface texturing technology on engine and transmission components, new low-viscosity and low-shear lubricants and additives, and tire designs that reduce rolling friction.

Influence of different configurations of a catalyst and a trap on particulate emission of a diesel passenger car  

Science Journals Connector (OSTI)

New particulate emission measurements performed on a diesel passenger car to see the influence of different configurations of after-treatment systems are reported. Five combinations of a particle trap and an oxidation catalyst are investigated. These configurations are discussed in view of particulate emission, measured by number and mass. All measurements were carried out at a chassis dynamometer of the EMPA. A diesel passenger car with an IDI engine was operated at four steady state conditions. Exhaust gas was diluted in a standard constant volume sampler (CVS) device (full flow dilution tunnel). Particulate size distributions were measured with a scanning mobility particle sizer (SMPS) and gravimetric measurements were performed according to regulations. Furthermore, measurements without CVS tunnel were done by using external dilution units to see the influence of the sampling method. We used a thermo desorber to distinguish volatile and non-volatile aerosol fractions and we analysed filter samples for determination of organic soluble fraction, water-soluble fraction and sulphur content. Huge differences depending on the configuration of the after-treatment system and load were observed. In general it was found that a large reduction of particulate emission could be obtained by using a particle trap. A catalyst converter has minor effect on particulate emission. Nucleation of new particles was observed under certain conditions depending on configuration and sampling method.

Cell division control by the Chromosomal Passenger Complex  

SciTech Connect (OSTI)

The Chromosomal Passenger Complex (CPC) consisting of Aurora B kinase, INCENP, Survivin and Borealin, is essential for genomic stability by controlling multiple processes during both nuclear and cytoplasmic division. In mitosis it ensures accurate segregation of the duplicated chromosomes by regulating the mitotic checkpoint, destabilizing incorrectly attached spindle microtubules and by promoting the axial shortening of chromosomal arms in anaphase. During cytokinesis the CPC most likely prevents chromosome damage by imposing an abscission delay when a chromosome bridge connects the two daughter cells. Moreover, by controlling proper cytoplasmic division, the CPC averts tetraploidization. This review describes recent insights on how the CPC is capable of conducting its various functions in the dividing cell to ensure chromosomal stability.

Policy effectiveness for road passenger transport emissions reductions across the world  

E-Print Network [OSTI]

The effectiveness of policy for emissions reductions in private passenger road transport depends on its ability to incentivise consumers to make choices oriented towards lower emissions vehicles. However, car purchase choices are known to be strongly socially determined, and this sector is highly diverse due to significant socio-economic differences between consumer groups. Here, we present a comprehensive analysis of the structure of the 2012 private passenger vehicle fleet-years in six major economies across the World (UK, USA, China, India, Japan and Brazil) in terms of prices, engine sizes and emissions. This is done in order to evaluate the effectiveness of existing and possible fiscal and technological change policies for emissions reductions. We provide tools to understand and evaluate the effectiveness of policy taking account of the distributive structure of prices and emissions in segments of a diverse market, both for conventional as well as unconventional engine technologies. We furthermore explai...

Experimental study on the effects of high/low pressure EGR proportion in a passenger car diesel engine  

Science Journals Connector (OSTI)

Abstract An experimental study was conducted to investigate the effects of the proportion between high pressure and low pressure exhaust gas recirculation (HP/LP EGR) on engine operation. The study focused on the characteristics of combustion, emissions, and fuel consumption in a 2.2L passenger car diesel engine. The experiments were performed under three part-load and steady-state operating conditions. The LP EGR portion was swept from 0 to 1, while the mass flow rate of fresh air and boost pressure were fixed. The results showed that the intake manifold temperature decreased gradually as the LP EGR portion increased due to its greater cooling capability by a longer supply line and an intercooler. However, the required cooling power for the intercooler increased because the LP EGR gas, which has a higher temperature than the fresh air, was induced upstream of the compressor. The lowered intake manifold temperature with the increase of the LP EGR portion led to the prolonged ignition delay of pilot injections, which resulted in a slightly higher peak heat release rate in the main combustion. A higher LP EGR portion showed a lower fuel consumption level than the HP EGR only case because the variable geometry turbocharger (VGT) nozzle opened more widely to maintain the boost pressure, which means a lower pumping loss. Nitrogen oxide (NOx) emissions were also decreased as the LP EGR portion increased due to lowered intake charge temperature. Consequently, it was possible to improve the trade-off relationship between \\{NOx\\} emissions and fuel consumption with the increase of the LP EGR portion under steady-state operating conditions.

Reduction of idle knock by EGR in a passenger car diesel engine  

SciTech Connect (OSTI)

In order to reduce the diesel idle knock, the effects of EGR on the idling characteristics were investigated on a passenger car equipped with an EGR Idle Knock Reduction System developed for practical use. It was found that EGR was effective not only for reducing idle knock but also for decreasing fuel consumption, smoke density, exhaust emissions and engine vibration. Moreover, the practical range and possibility of the EGR Idle Knock Reduction System were found by clarifying the relationship between EGR, injection timing, cooling water temperature, noise level and fuel consumption.

Transient in cab noise investigation on a light duty diesel passenger vehicle.  

Science Journals Connector (OSTI)

A diesel engine in cab sound quality for passenger car market is scrutinized more closely than in the mid? to heavy duty diesel truck applications. This is obviously due to the increasing expectations from the customers for gasolinelike sound quality. This paper deals with a sound quality issue recently investigated on a light duty diesel engine for a passenger van application. The objectionable noise complaint occurred during the vehicle transient operating conditions and was found to be caused by the change in the pilot quantity over a very short period of time. The root cause of the noise complaint was investigated on the noise complaint vehicle as well as simultaneously on a standalone engine in the noise test cell. Several critical combustion and performance parameters were recorded for diagnosing the issue. In addition various standard sound quality metrics were employed to differentiate the sound quality of the objectionable noise. The issue was resolved and verified by making appropriate changes to the engine calibration without affecting key requirements such as emissions and fuel economy. Finally the findings from the experimental tests are summarized and appropriate conclusions are drawn with respect to understanding characterizing and resolving this transient combustion related impulsive powertrain interior noise issue.

Cotton flow

Using the conformally invariant Cotton tensor, we define a geometric flow, the "Cotton flow", which is exclusive to three dimensions. This flow tends to evolve the initial metrics into conformally flat ones, and is somewhat orthogonal to the Yamabe flow, the latter being a flow within a conformal class. We define an entropy functional, and study the flow of nine homogeneous spaces both numerically and analytically. In particular, we show that the arbitrarily deformed homogeneous 3-sphere flows into the round 3-sphere. Two of the nine homogeneous geometries, which are degenerated by the Ricci flow, are left intact by the Cotton flow.

Analysis of different control strategies for the simultaneous reduction of CO2 and NOx emissions of a diesel hybrid passenger car  

Science Journals Connector (OSTI)

Different control strategies for a diesel parallel hybrid passenger car were evaluated through numerical simulations. Two different control strategies were analysed: the first focused on fuel consumption minimisation, the second on NOx emissions cuts. Each of these goals was addressed through two different methodologies, the first based on a group of heuristic laws, the second focused on the instantaneous minimisation of a cost function that takes into account both the fuel and battery energies. A first assessment of the potential of a diesel hybrid passenger car as far as fuel consumption and NOx emissions reductions are concerned was obtained.

Energy use and CO2 emissions reduction potential in passenger car fleet using zero emission vehicles and lightweight materials  

Science Journals Connector (OSTI)

Introduction of \\{ZEVs\\} (zero emission vehicles) and lightweight materials in a conventional steel-intensive internal combustion engine vehicle fleet will affect energy consumption and automotive material requirements. We developed a bottom-up dynamic accounting model of the light-duty vehicle fleet, including vehicle production and disposal, with detailed coverage of powertrains and automotive materials. The model was used to study the potential for energy consumption and CO2 emissions reduction of \\{ZEVs\\} and lightweight materials in the Colombian passenger car fleet from 2010 to 2050. Results indicate that passenger car stock in Colombia is increased by 6.6 times between 2010 and 2050. In the base scenario energy consumption and CO2 emissions are increased by 5.5 and 4.9 times respectively. Lightweighting and battery electric vehicles offer the largest tank-to-wheel energy consumption and CO2 emissions reductions, 48 and 61% respectively, compared to 2050 baseline values. Slow stock turnover and fleet size increment prevent larger reductions. Switching to electric powertrains has larger impact than lightweighting on energy consumption and CO2 emissions. Iron and steel remain major materials in new cars. Aluminum consumption increases in all scenarios; while carbon fiber reinforced polymer consumption only increases due to fuel cell hybrid electric vehicle or lightweight vehicle use.

Pouring flows  

Science Journals Connector (OSTI)

Free surface flows of a liquid poured from a container are calculated numerically for various configurations of the lip. The flow is assumed to be steady two dimensional and irrotational; the liquid is treated as inviscid and incompressible; and gravity is taken into account. It is shown that there are jetlike flows with two free surfaces and other flows with one free surface which follow along the underside of the lip or spout. The latter flows occur in the well?known teapot effect which was treated previously without including gravity. Some of the results are applicable also to flows over weirs and spillways.

Multi-parametric study of the effect of materials substitution on life cycle energy use and waste generation of passenger car structures  

Science Journals Connector (OSTI)

Aluminium and fibre reinforced plastics have been put forward as alternatives for steel to reduce passenger car weight and save energy during use. Often-reported drawbacks are increased energy for production and reduced recyclability, and hence, increased waste generation. This study considers the merits of the alternatives by making a multi-parametric comparison of the life cycle energy use and waste generation of three lightweight alternatives to todays all-steel car structure. The development level, captured as the percentage of high strength steel in todays car structure, is identified as an important new variable in the analysis of automotive life cycle energy use.

Low volume flow meter  

DOE Patents [OSTI]

The low flow monitor provides a means for determining if a fluid flow meets a minimum threshold level of flow. The low flow monitor operates with a minimum of intrusion by the flow detection device into the flow. The electrical portion of the monitor is externally located with respect to the fluid stream which allows for repairs to the monitor without disrupting the flow. The electronics provide for the adjustment of the threshold level to meet the required conditions. The apparatus can be modified to provide an upper limit to the flow monitor by providing for a parallel electronic circuit which provides for a bracketing of the desired flow rate.

Study of the impact of rainfall on freeway traffic flow in Southeast China  

Science Journals Connector (OSTI)

The purpose of this paper is to quantify the impact of rainfall on freeway traffic flow using toll station data and precipitation data. Five rainfall categories were classified based on precipitation intensity. Hourly traffic volume and travel times were retrieved and analysed in three spatial scales: at toll stations, on freeway sections between two toll stations, and on freeway corridors composed of multiple sections. Travel times for passenger cars in each rainfall category were studied and the impact of rainfall on traffic volume and travel time was quantified. The non-parametric Kruskal-Wallis test was performed to check the significance of difference among various categories.Calculated traffic volume reduction coefficients and travel time incremental coefficients for each rainfall category were compared with existing research results, which showed obvious differences. Potential causes are discussed to explain the discrepancy in coefficient values.

Flow Distances on Open Flow Networks  

E-Print Network [OSTI]

Open flow network is a weighted directed graph with a source and a sink, depicting flux distributions on networks in the steady state of an open flow system. Energetic food webs, economic input-output networks, and international trade networks, are open flow network models of energy flows between species, money or value flows between industrial sectors, and goods flows between countries, respectively. Flow distances (first-passage or total) between any given two nodes $i$ and $j$ are defined as the average number of transition steps of a random walker along the network from $i$ to $j$ under some conditions. They apparently deviate from the conventional random walk distance on a closed directed graph because they consider the openness of the flow network. Flow distances are explicitly expressed by underlying Markov matrix of a flow system in this paper. With this novel theoretical conception, we can visualize open flow networks, calculating centrality of each node, and clustering nodes into groups. We apply fl...

Real-world fuel consumption and CO2 (carbon dioxide) emissions by driving conditions for light-duty passenger vehicles in China  

Science Journals Connector (OSTI)

Abstract The increasing discrepancy between on-road and type-approval fuel consumption for \\{LDPVs\\} (light-duty passenger vehicles) has attracted tremendous attention. We measured on-road emissions for 60 \\{LDPVs\\} in three China's cities and calculated their fuel consumption and CO2 (carbon dioxide) emissions. We further evaluated the impacts of variations in area-averaged speed on relative fuel consumption of gasoline \\{LDPVs\\} for the UAB (urban area of Beijing). On-road fuel consumption under the average driving pattern is 102% higher than that normalized to the NEDC (new European driving cycle) cycle for all tested vehicles, and the on-road NEDC-normalized fuel consumption is higher by 3012% compared to type-approval values for gasoline vehicles. We observed very strong correlations between relative fuel consumption and average speed. Traffic control applied to \\{LDPVs\\} driving within the UAB during weekdays can substantially reduce total fleet fuel consumption by 235% during restriction hours by limiting vehicle use and improving driving conditions. Our results confirmed that a new cycle for the type approval test for \\{LDPVs\\} with more real-world driving features is of great necessity. Furthermore, enhanced traffic control measures could play an important role in mitigating real-world fuel consumption and CO2 emissions for \\{LDPVs\\} in China.

Low flow fume hood  

DOE Patents [OSTI]

A fume hood is provided having an adequate level of safety while reducing the amount of air exhausted from the hood. A displacement flow fume hood works on the principal of a displacement flow which displaces the volume currently present in the hood using a push-pull system. The displacement flow includes a plurality of air supplies which provide fresh air, preferably having laminar flow, to the fume hood. The displacement flow fume hood also includes an air exhaust which pulls air from the work chamber in a minimally turbulent manner. As the displacement flow produces a substantially consistent and minimally turbulent flow in the hood, inconsistent flow patterns associated with contaminant escape from the hood are minimized. The displacement flow fume hood largely reduces the need to exhaust large amounts of air from the hood. It has been shown that exhaust air flow reductions of up to 70% are possible without a decrease in the hood's containment performance. The fume hood also includes a number of structural adaptations which facilitate consistent and minimally turbulent flow within a fume hood.

The dependence of the conductivity on the system parameters arising from the turbulent flow is very different from that due to scattering.

Muffler Theory Considering Flow  

Science Journals Connector (OSTI)

The effect of a steady subsonic flow component upon the acoustical properties of pipes and of laminar and turbulent flow resistances is accounted for in an elementary fashion. The effect of the alternating or acoustic component upon the steady?flow properties is treated likewise. Acoustic transmission loss referred to the end radiation from a pipe is related to back pressure (increase in steady pressure due to the muffler). Equivalent circuits and diagrams of transmission loss vs back pressure are presented for some simple arrangements of pipes volumes irises and flow resistances.

Shroud leakage flow discouragers  

DOE Patents [OSTI]

A turbine assembly includes a plurality of rotor blades comprising a root portion, an airfoil having a pressure sidewall and a suction sidewall, and a top portion having a cap. An outer shroud is concentrically disposed about said rotor blades, said shroud in combination with said tip portions defining a clearance gap. At least one circumferential shroud leakage discourager is disposed within the shroud. The leakage discourager(s) increase the flow resistance and thus reduce the flow of hot gas flow leakage for a given pressure differential across the clearance gap to improve overall turbine efficiency.

Noise Levels due to Trains  

Science Journals Connector (OSTI)

Some fifty freight and passenger trains were investigated at distances between 25 and 1000 ft. The decrease of sound?pressure levels with increasing distance indicates that whistles are to be considered as point sources but engines and track noise are line sources out to distances comparable with the lengths of the source. All engines showed a pure tone in the region of 100 cps and freight engines a second tone at about 300 cps when pulling hard. Otherwise freight engines showed little change in level whatever the operating conditions. Noise from passenger engines showed marked changes in level since they operate with much more exaggerated changes in power than freight engines. Track noise depends on the rolling stockfreight cars and run?of?the?mill passenger cars have very similar noise spectra whereas the deluxe cars used on prestige trains have spectra lying 10 to 20 db lower in all frequency bands. All the cars have coil springs but the latter alone have hydraulic shock absorbers.

Holographic supersymmetric membrane flows  

Science Journals Connector (OSTI)

The M-theory lift of SU(3) ? U(1)R-invariant RG flow via a combinatorical use of the four-dimensional flow and 11-dimensional EinsteinMaxwell equations was found previously. By taking the three internal coordinates differently and preserving only the SU(3) symmetry from the CP2 space, we find a new 11-dimensional solution of the SU(3)-invariant RG flow interpolating from the SO(8)-invariant UV fixed point to the SU(3) ? U(1)R-invariant IR fixed point in four dimensions. We describe how the corresponding three-dimensional superconformal ChernSimons matter theory deforms. By replacing the above CP2 space with the EinsteinKahler twofold, we also find out a new 11-dimensional solution of the SU(2) ? U(1)-invariant RG flow connecting the above two fixed points in four dimensions.

Two-phase flow studies  

SciTech Connect (OSTI)

The two-phase flow program is directed at understanding the hydrodynamics of two-phase flows. The two-phase flow regime is characterized by a series of flow patterns that are designated as bubble, slug, churn, and annular flow. Churn flow has received very little scientific attention. This lack of attention cannot be justified because calculations predict that the churn flow pattern will exist over a substantial portion of the two-phase flow zone in producing geothermal wells. The University of Houston is experimentally investigating the dynamics of churn flow and is measuring the holdup over the full range of flow space for which churn flow exists. These experiments are being conducted in an air/water vertical two-phase flow loop. Brown University has constructed and is operating a unique two-phase flow research facility specifically designed to address flow problems of relevance to the geothermal industry. An important feature of the facility is that it is dedicated to two-phase flow of a single substance (including evaporation and condensation) as opposed to the case of a two-component two-phase flow. This facility can be operated with horizontal or vertical test sections of constant diameter or with step changes in diameter to simulate a geothermal well profile.

Evaluation of flow hood measurements for residential register flows  

SciTech Connect (OSTI)

Flow measurement at residential registers using flow hoods is becoming more common. These measurements are used to determine if the HVAC system is providing adequate comfort, appropriate flow over heat exchangers and in estimates of system energy losses. These HVAC system performance metrics are determined by using register measurements to find out if individual rooms are getting the correct airflow, and in estimates of total air handler flow and duct air leakage. The work discussed in this paper shows that commercially available flow hoods are poor at measuring flows in residential systems. There is also evidence in this and other studies that flow hoods can have significant errors even when used on the non-residential systems they were originally developed for. The measurement uncertainties arise from poor calibrations and the sensitivity of exiting flow hoods to non-uniformity of flows entering the device. The errors are usually large--on the order of 20% of measured flow, which is unacceptably high for most applications. Active flow hoods that have flow measurement devices that are insensitive to the entering airflow pattern were found to be clearly superior to commercially available flow hoods. In addition, it is clear that current calibration procedures for flow hoods may not take into account any field application problems and a new flow hood measurement standard should be developed to address this issue.

Workshop on hypersonic flow  

SciTech Connect (OSTI)

An overview is given of research activity on the application of computational fluid dynamics (CDF) for hypersonic propulsion systems. After the initial consideration of the highly integrated nature of air-breathing hypersonic engines and airframe, attention is directed toward computations carried out for the components of the engine. A generic inlet configuration is considered in order to demonstrate the highly three dimensional viscous flow behavior occurring within rectangular inlets. Reacting flow computations for simple jet injection as well as for more complex combustion chambers are then discussed in order to show the capability of viscous finite rate chemical reaction computer simulations. Finally, the nozzle flow fields are demonstrated, showing the existence of complex shear layers and shock structure in the exhaust plume. The general issues associated with code validation as well as the specific issue associated with the use of CFD for design are discussed. A prognosis for the success of CFD in the design of future propulsion systems is offered.

I discuss the multiphase nature of the intracluster medium whose neglect can lead to overestimates of the baryon fraction of clusters by up to a factor of two. The multiphase form of the cooling flow equations are derived and reduced to a simple form for a wide class of self-similar density distributions. It is shown that steady-state cooling flows are \\emph{not} consistent with all possible emissivity profiles which can therefore be used as a test of the theory. In combination, they provide strong constraints on the mass distribution within the cooling radius.

Furthermore, conflicts or coordination problems of intersecting or merging flows are considered as well. Making assumptions regarding the permeability of the intersection as a function of the conflicting flows and the queue lengths, we find self-organized oscillations in the flows similar to the operation of traffic lights.

Structural power flow measurement  

SciTech Connect (OSTI)

Previous investigations of structural power flow through beam-like structures resulted in some unexplained anomalies in the calculated data. In order to develop structural power flow measurement as a viable technique for machine tool design, the causes of these anomalies needed to be found. Once found, techniques for eliminating the errors could be developed. Error sources were found in the experimental apparatus itself as well as in the instrumentation. Although flexural waves are the carriers of power in the experimental apparatus, at some frequencies longitudinal waves were excited which were picked up by the accelerometers and altered power measurements. Errors were found in the phase and gain response of the sensors and amplifiers used for measurement. A transfer function correction technique was employed to compensate for these instrumentation errors.

The outer peripheral surfaces of the heater pads are configured as segments of a cylinder and form a full cylinder when taken together. A plurality of temperature sensors are located on each pad so as to extend along the length and across the width thereof, with a heating element being located in each pad beneath the temperature sensors. An expansion mechanism driven by a clamping motor provides expansion and retraction of the heater pads and expandable packet-type seals are provided along the probe above and below the heater pads.

Attractor Flows from Defect Lines  

E-Print Network [OSTI]

Deforming a two dimensional conformal field theory on one side of a trivial defect line gives rise to a defect separating the original theory from its deformation. The Casimir force between these defects and other defect lines or boundaries is used to construct flows on bulk moduli spaces of CFTs. It turns out, that these flows are constant reparametrizations of gradient flows of the g-functions of the chosen defect or boundary condition. The special flows associated to supersymmetric boundary conditions in N=(2,2) superconformal field theories agree with the attractor flows studied in the context of black holes in N=2 supergravity.

UZ Flow Models and Submodels  

SciTech Connect (OSTI)

The purpose of this report is to document the unsaturated zone (UZ) flow models and submodels, as well as the flow fields that have been generated using the UZ flow model(s) of Yucca Mountain, Nevada. In this report, the term ''UZ model'' refers to the UZ flow model and the several submodels, which include tracer transport, temperature or ambient geothermal, pneumatic or gas flow, and geochemistry (chloride, calcite, and strontium) submodels. The term UZ flow model refers to the three-dimensional models used for calibration and simulation of UZ flow fields. This work was planned in the ''Technical Work Plan (TWP) for: Unsaturated Zone Flow Analysis and Model Report Integration'' (BSC 2004 [DIRS 169654], Section 1.2.7). The table of included Features, Events, and Processes (FEPs), Table 6.2-11, is different from the list of included FEPs assigned to this report in the ''Technical Work Plan for: Unsaturated Zone Flow Analysis and Model Report Integration'' (BSC 2004 [DIRS 169654], Table 2.1.5-1), as discussed in Section 6.2.6. The UZ model has revised, updated, and enhanced the previous UZ model (BSC 2001 [DIRS 158726]) by incorporating the repository design with new grids, recalibration of property sets, and more comprehensive validation effort. The flow fields describe fracture-fracture, matrix-matrix, and fracture-matrix liquid flow rates, and their spatial distributions as well as moisture conditions in the UZ system. These three-dimensional UZ flow fields are used directly by Total System Performance Assessment (TSPA). The model and submodels evaluate important hydrogeologic processes in the UZ as well as geochemistry and geothermal conditions. These provide the necessary framework to test hypotheses of flow and transport at different scales, and predict flow and transport behavior under a variety of climatic conditions. In addition, the limitations of the UZ model are discussed in Section 8.11.

Fluid flow monitoring device  

DOE Patents [OSTI]

A flow meter and temperature measuring device are described comprising a tube with a body centered therein for restricting flow and a sleeve at the upper end of the tube to carry several channels formed longitudinally in the sleeve to the appropriate axial location where they penetrate the tube to allow pressure measurements and temperature measurements with thermocouples. The high pressure measurement is made using a channel penetrating the tube away from the body and the low pressure measurement is made at a location at the widest part of the body. An end plug seals the end of the device and holes at its upper end allow fluid to pass from the interior of the tube into a plenum. The channels are made by cutting grooves in the sleeve, the grooves widened at the surface of the sleeve and then a strip of sleeve material is welded to the grooves closing the channels. Preferably the sleeve is packed with powdered graphite before cutting the grooves and welding the strips. 7 figures.

Active combustion flow modulation valve  

DOE Patents [OSTI]

A flow modulation valve has a slidably translating hollow armature with at least one energizable coil wound around and fixably attached to the hollow armature. The energizable coil or coils are influenced by at least one permanent magnet surrounding the hollow armature and supported by an outer casing. Lorentz forces on the energizable coils which are translated to the hollow armature, increase or decrease the flow area to provide flow throttling action. The extent of hollow armature translation depends on the value of current supplied and the direction of translation depends on the direction of current flow. The compact nature of the flow modulation valve combined with the high forces afforded by the actuator design provide a flow modulation valve which is highly responsive to high-rate input control signals.

Module bay with directed flow  

DOE Patents [OSTI]

A module bay requires less cleanroom airflow. A shaped gas inlet passage can allow cleanroom air into the module bay with flow velocity preferentially directed toward contaminant rich portions of a processing module in the module bay. Preferential gas flow direction can more efficiently purge contaminants from appropriate portions of the module bay, allowing a reduced cleanroom air flow rate for contaminant removal. A shelf extending from an air inlet slit in one wall of a module bay can direct air flowing therethrough toward contaminant-rich portions of the module bay, such as a junction between a lid and base of a processing module.

Effect of flow fluctuations and nonflow on elliptic flow methods  

SciTech Connect (OSTI)

We discuss how the different estimates of elliptic flow are influenced by flow fluctuations and nonflow effects. It is explained why the event-plane method yields estimates between the two-particle correlation methods and the multiparticle correlation methods. It is argued that nonflow effects and fluctuations cannot be disentangled without other assumptions. However, we provide equations where, with reasonable assumptions about fluctuations and nonflow, all measured values of elliptic flow converge to a unique mean v_2,PP elliptic flow in the participant plane and, with a Gaussian assumption on eccentricity fluctuations, can be converted to the mean v_2,RP in the reaction plane. Thus, the 20percent spread in observed elliptic flow measurements from different analysis methods is no longer mysterious.

Proper planning improves flow drilling  

SciTech Connect (OSTI)

Underbalanced operations reduce formation damage, especially in horizontal wells where zones are exposed to mud for longer time periods. Benefits, risks, well control concerns, equipment and issues associated with these operations are addressed in this paper. Flow drilling raises many concerns, but little has been published on horizontal well control and flow drilling operations. This article covers planning considerations for flow drilling, but does not address horizontal ''overbalanced'' drilling because considerations and equipment are the same as in vertical overbalanced drilling and many references address that subject. The difference in well control between vertical and horizontal overbalanced drilling is fluid influx behavior and how that behavior affects kill operations.

Zonal flow as pattern formation  

SciTech Connect (OSTI)

Zonal flows are well known to arise spontaneously out of turbulence. We show that for statistically averaged equations of the stochastically forced generalized Hasegawa-Mima model, steady-state zonal flows, and inhomogeneous turbulence fit into the framework of pattern formation. There are many implications. First, the wavelength of the zonal flows is not unique. Indeed, in an idealized, infinite system, any wavelength within a certain continuous band corresponds to a solution. Second, of these wavelengths, only those within a smaller subband are linearly stable. Unstable wavelengths must evolve to reach a stable wavelength; this process manifests as merging jets.

Subcritical dynamos in shear flows  

E-Print Network [OSTI]

Identifying generic physical mechanisms responsible for the generation of magnetic fields and turbulence in differentially rotating flows is fundamental to understand the dynamics of astrophysical objects such as accretion disks and stars. In this paper, we discuss the concept of subcritical dynamo action and its hydrodynamic analogue exemplified by the process of nonlinear transition to turbulence in non-rotating wall-bounded shear flows. To illustrate this idea, we describe some recent results on nonlinear hydrodynamic transition to turbulence and nonlinear dynamo action in rotating shear flows pertaining to the problem of turbulent angular momentum transport in accretion disks. We argue that this concept is very generic and should be applicable to many astrophysical problems involving a shear flow and non-axisymmetric instabilities of shear-induced axisymmetric toroidal velocity or magnetic fields, such as Kelvin-Helmholtz, magnetorotational, Tayler or global magnetoshear instabilities. In the light of several recent numerical results, we finally suggest that, similarly to a standard linear instability, subcritical MHD dynamo processes in high-Reynolds number shear flows could act as a large-scale driving mechanism of turbulent flows that would in turn generate an independent small-scale dynamo.

Pressure and flow characteristics of restrictive flow orifice devices.  

SciTech Connect (OSTI)

A Restrictive Flow Orifice (RFO) can be used to enhance the safe design of a pressure system in several ways. Pressure systems frequently incorporate a regulator and relief valve to protect the downstream equipment from accidental overpressure caused by regulator failure. Analysis frequently shows that in cases of high-flow regulator failure, the downstream pressure may rise significantly above the set pressure of the relief valve. This is due to limited flow capacity of the relief valve. A different regulator or relief valve may need to be selected. A more economical solution to this problem is to use an RFO to limit the maximum system flow to acceptable limits within the flow capacity of the relief valve, thereby enhancing the overpressure protection of laboratory equipment. An RFO can also be used to limit the uncontrolled release of system fluid (gas or liquid) upon component or line failure. As an example, potential asphyxiation hazards resultant from the release of large volumes of inert gas from a 'house' nitrogen system can be controlled by the use of an RFO. This report describes a versatile new Sandia-designed RFO available from the Swagelok Company and specifies the gas flow characteristics of this device. Two sizes, 0.010 and 0.020 inch diameter RFOs are available. These sizes will allow enhanced safety for many common applications. This new RFO design are now commercially available and provide advantages over existing RFOs: a high pressure rating (6600 psig); flow through the RFO is equal for either forward or reverse directions; they minimize the potential for leakage by incorporating the highest quality threaded connections; and can enhance the safety of pressure systems.

Mach flow angularity probes for scramjet engine flow path diagnostics  

SciTech Connect (OSTI)

Mach-flow angularity (MFA) probes were developed for use in scramjet flow path probe rakes. Prototype probes were fabricated to demonstrate the assembly processes (numerical control machining, furnace brazing, and electron beam welding). Tests of prototype probes confirmed the thermal durability margins and life cycle. Selected probes were calibrated in air at Mach numbers from 1.75 to 6.0. Acceptance criteria for the production probes stressed thermal durability and pressure (and, consequently, Mach number) measurement quality. This new water-cooled MFA probe has 0.397-cm shaft diameter and is capable of withstanding heat fluxes of 2.724 kW/sq cm.

There are public areas, shared laboratories, shared office space, and privately assigned places. A newcomer to the building should become familiar with locations of the key areas. Stairs and Elevators - Building 555 The central main staircase and a passenger elevator are for personnel traffic only. Each wing has a staircase. There is a rear staircase for traffic directly to service areas. The building has a freight elevator at the rear core. Flammable material, chemicals, solvents, gas cylinders, etc. can be transported in the freight elevator but not in the passenger elevator. Do not ride with gas cylinders or dewars charged with cryogens as the presence of these in a confined space introduces a suffocation hazard.

POSITIVE TRAIN CONTROL  

E-Print Network [OSTI]

Abstract Positive train control (PTC) is a modern system of monitoring and controlling train movements to provide advanced safety. This system uses the latest technology in mobile wireless communication. In Sept 2008, the US Congress considered a new rail safety law that sets a deadline of 2015 for implementation of positive train control (PTC) technology across most of the U.S. rail network. The bill was developed in response to the collision of a Metro link passenger train and a Union Pacific freight train Sept. 12 in California, which resulted in the deaths of 25 and injuries to more than 135 Metrolink passengers.

Assessing current vehicle performance and simulating the performance of hydrogen and hybrid cars  

Science Journals Connector (OSTI)

A measure of the efficiency in transforming energy input into transport work is defined and applied to road vehicles as well as to sea, air and rail vehicles for passenger or freight transportation. The insight obtained with this measure is compared with the results of applying the conventional measure of kilometres per unit of energy for current fleets of vehicles. Then, simulation methods are used to assess the performance of fuel cell vehicles, electric vehicles and hybrids between the two. The latter are found to provide an optimum performance for a small, efficient passenger car.

Renormalization Group and the Ricci flow  

E-Print Network [OSTI]

We discuss from a geometric point of view the connection between the renormalization group flow for non--linear sigma models and the Ricci flow. This offers new perspectives in providing a geometrical landscape for 2D quantum field theories. In particular we argue that the structure of Ricci flow singularities suggests a natural way for extending, beyond the weak coupling regime, the embedding of the Ricci flow into the renormalization group flow.

11 - Knowledge Flow in Universities  

Science Journals Connector (OSTI)

In this chapter, a typical American university is chosen as a model for the quantitative analysis for the flow of knowledge in a reasonably well-defined academic setting. Knowledge flow assumes quantifiable patterns and much like the flow and retention of rain water over a given terrain of land; the quality (of teaching) and quantity (number of credit hours) of knowledge retained by students is estimated on a qualitative and quantitative basis. The model presented in this chapter is entirely generic. It can be applied in any center of learning and during any period of training, residency in limited time frame, or even to the evolution of species as they gain survival skills, and build their knowledge potential to survive, another generation, calamity, meteor fall, a catastrophic disaster, or a global nuclear fall-out. Though the probability of outcome is not accurately known, it is still bounded by confidence limits.

Pressure compensated flow control valve  

DOE Patents [OSTI]

The invention is an air flow control valve which is capable of maintaining a constant flow at the outlet despite changes in the inlet or outlet pressure. The device consists of a shell assembly with an inlet chamber and outlet chamber separated by a separation plate. The chambers are connected by an orifice. Also located within the inlet chamber is a port controller assembly. The port controller assembly consists of a differential pressure plate and port cap affixed thereon. The cap is able to slide in and out of the orifice separating the inlet and outlet chambers. When the pressure differential is sufficient, the differential pressure plate rises or falls to maintain a constant air flow. Movement of the port controller assembly does not require the use of seals, diaphragms, tight tolerances, bushings, bearings, hinges, guides, or lubricants.

Flow optimization in diving helmets  

SciTech Connect (OSTI)

Improved carbon dioxide transport from the annular space between the head and helmet is necessary to reduce fresh gas flow and associated noise. This paper gives an overview of new techniques for investigating this transport, and for optimizing helmet flow to remove CO{sub 2}. An analytical model predicts inhaled carbon dioxide fraction in terms of helmet and respiration characteristics. Fundamental behavior over a wide range of helmet parameters is computed. An experimental model uses Reynolds scaling with water and dye to simulate fresh gas and carbon dioxide respectively. The water/dye model supports measurement of inhaled dye concentration, and flow visualization. Detailed behavior is investigated for one helmet with air/CO{sub 2} and water/dye experiments. Results support validity of the analytic and water models, provide new insight to CO{sub 2} transport mechanisms, and suggest directions for optimizing helmet design.

Life Cycle Assessment Comparing the Use of Jatropha Biodiesel in the Indian Road and Rail Sectors  

SciTech Connect (OSTI)

This life cycle assessment of Jatropha biodiesel production and use evaluates the net greenhouse gas (GHG) emission (not considering land-use change), net energy value (NEV), and net petroleum consumption impacts of substituting Jatropha biodiesel for conventional petroleum diesel in India. Several blends of biodiesel with petroleum diesel are evaluated for the rail freight, rail passenger, road freight, and road-passenger transport sectors that currently rely heavily on petroleum diesel. For the base case, Jatropha cultivation, processing, and use conditions that were analyzed, the use of B20 results in a net reduction in GHG emissions and petroleum consumption of 14% and 17%, respectively, and a NEV increase of 58% compared with the use of 100% petroleum diesel. While the road-passenger transport sector provides the greatest sustainability benefits per 1000 gross tonne kilometers, the road freight sector eventually provides the greatest absolute benefits owing to substantially higher projected utilization by year 2020. Nevertheless, introduction of biodiesel to the rail sector might present the fewest logistic and capital expenditure challenges in the near term. Sensitivity analyses confirmed that the sustainability benefits are maintained under multiple plausible cultivation, processing, and distribution scenarios. However, the sustainability of any individual Jatropha plantation will depend on site-specific conditions.

Liquid metal Flow Meter - Final Report  

SciTech Connect (OSTI)

Measuring the flow of liquid metal presents serious challenges. Current commercially-available flow meters use ultrasonic, electromagnetic, and other technologies to measure flow, but are inadequate for liquid metal flow measurement because of the high temperatures required by most liquid metals. As a result of the reactivity and high temperatures of most liquid metals, corrosion and leakage become very serious safety concerns. The purpose of this project is to develop a flow meter for Lockheed Martin that measures the flow rate of molten metal in a conduit.

Cascade redox flow battery systems  

DOE Patents [OSTI]

A reduction/oxidation ("redox") flow battery system includes a series of electrochemical cells arranged in a cascade, whereby liquid electrolyte reacts in a first electrochemical cell (or group of cells) before being directed into a second cell (or group of cells) where it reacts before being directed to subsequent cells. The cascade includes 2 to n stages, each stage having one or more electrochemical cells. During a charge reaction, electrolyte entering a first stage will have a lower state-of-charge than electrolyte entering the nth stage. In some embodiments, cell components and/or characteristics may be configured based on a state-of-charge of electrolytes expected at each cascade stage. Such engineered cascades provide redox flow battery systems with higher energy efficiency over a broader range of current density than prior art arrangements.

Anisotropic Flow from RHIC to the LHC  

E-Print Network [OSTI]

Anisotropic flow is recognized as one of the main observables providing information on the early stage of a heavy-ion collision. At RHIC the large observed anisotropic flow and its successful description by ideal hydrodynamics is considered evidence for an early onset of thermalization and almost ideal fluid properties of the produced strongly coupled Quark Gluon Plasma. This write-up discusses some key RHIC anisotropic flow measurements and for anisotropic flow at the LHC some predictions.

Building up the elliptic flow: analytical insights  

E-Print Network [OSTI]

In this paper, we present a fully analytical description of the early-stage formation of elliptic flow in relativistic viscous hydrodynamics. We first construct an elliptic deformation of Gubser flow which is a boost invariant solution of the Navier-Stokes equation with a nontrivial transverse profile. We then analytically calculate the momentum anisotropy of the flow as a function of time and discuss the connection with the empirical formula by Bhalerao {\\it et al.} regarding the viscosity dependence of elliptic flow.

Entrained Flow Gasifiers Entrained Flow Gasifiers Uhde - Prenflo PRENFLO(tm) is a pressurized (>40 bar), entrained-flow gasification technology first demonstrated in the late 1980s, and currently offered by Uhde (Krupp Koppers merged with Uhde in 1997). Notably, PRENFLO(tm) is the gasification technology used at the world's largest solid feedstock-based gasifier at ELCOGAS's Puertollano IGCC plant in Spain (which is fueled with a 50%/50% mix of petcoke and coal). PRENFLO(tm) is offered in two varieties, the PRENFLO(tm) PSG (with steam generation) depicted in Figures 1 & 2, and PRENFLO(tm) PDQ (direct quench) as depicted in Figures 3 & 4. The gasifier conditions and feed characteristics are similar, but PRENFLO(tm) PSG includes an integrated waste heat boiler and uses compressed recirculated quench gas as illustrated in Figure 2, resulting in relatively low moisture raw syngas at relatively high exit temperature. PRENFLO(tm) PDQ uses direct quench, resulting in considerably lower raw syngas exit temperature (200-250°C) which is saturated. Uhde notes that PDQ has lower investment cost and shorter construction and supply schedule than PSG, though this would be at the performance expense of somewhat lower thermal efficiency and slightly higher concentration of CO2 in raw syngas.

Cyclotron resonance in plasma flow  

SciTech Connect (OSTI)

This paper is devoted to the mechanism of particle acceleration via resonant interaction with the electromagnetic circular wave propagating along the inhomogeneous background magnetic field in the presence of a plasma flow. We consider the system where the plasma flow velocity is large enough to change the direction of wave propagation in the rest frame. This system mimics a magnetic field configuration typical for inner structure of a quasi-parallel shock wave. We consider conditions of gyroresonant interaction when the force corresponding to an inhomogeneity of the background magnetic field is compensated by the Lorentz force of the wave-magnetic field. The wave-amplitude is assumed to be about 10% of the background magnetic field. We show that particles can gain energy if kv{sub sw}>?>kv{sub sw}??{sub c} where k is the wave number, v{sub sw} is a plasma flow velocity, and ? and ?{sub c} are the wave frequency and the particle gyrofrequency, respectively. This mechanism of acceleration resembles the gyrosurfing mechanism, but the effect of the electrostatic field is replaced by the effect of the magnetic field inhomogeneity.

Cognitive Radio will revolutionize American transportation  

ScienceCinema (OSTI)

Cognitive Radio will revolutionize American transportation. Through smart technology, it will anticipate user needs; detect available bandwidths and frequencies then seamlessly connect vehicles, infrastructures, and consumer devices; and it will support the Department of Transportation IntelliDrive Program, helping researchers, auto manufacturers, and Federal and State officials advance the connectivity of US transportation systems for improved safety, mobility, and environmental conditions. Using cognitive radio, a commercial vehicle will know its driver, onboard freight and destination route. Drivers will save time and resources communicating with automatic toll booths and know ahead of time whether to stop at a weigh station or keep rolling. At accident scenes, cognitive radio sensors on freight and transportation modes can alert emergency personnel and measure on-site, real-time conditions such as a chemical leak. The sensors will connect freight to industry, relaying shipment conditions and new delivery schedules. For industry or military purposes, cognitive radio will enable real-time freight tracking around the globe and its sensory technology can help prevent cargo theft or tampering by alerting shipper and receiver if freight is tampered with while en route. For the average consumer, a vehicle will tailor the transportation experience to the passenger such as delivering age-appropriate movies via satellite. Cognitive radio will enhance transportation safety by continually sensing what is important to the user adapting to its environment and incoming information, and proposing solutions that improve mobility and quality of life.

DOE Patents [OSTI]

A chemical preconcentrator with integral thermal flow sensor can be used to accurately measure fluid flow rate in a microanalytical system. The thermal flow sensor can be operated in either constant temperature or constant power mode and variants thereof. The chemical preconcentrator with integral thermal flow sensor can be fabricated with the same MEMS technology as the rest of the microanlaytical system. Because of its low heat capacity, low-loss, and small size, the chemical preconcentrator with integral thermal flow sensor is fast and efficient enough to be used in battery-powered, portable microanalytical systems.

Energy focusing in bubbly flows  

Science Journals Connector (OSTI)

Sonoluminescence cavitation damage at surfaces and cavitation in accelerating flows are realizations of spectacular levels of energy focusing in nature. In a resonant sound field a single trapped bubble of gas can focus the ambient sound energy by 12 orders of magnitude to generate a clocklike string of picosecond flashes of ultraviolet light. [Barber et al. Defining the unknowns of sonoluminescence Phys. Rep. 281 65 (1977)]. In more complicated geometries a high level of sound leads to the formation of hemispherical bubbles attached to an exposed surface. These bubbles also emit light and in addition damage the surface. Measurements show that the pulsation of these bubbles maintains the hemispherical symmetry [Weninger et al. Sonoluminescence from an isolated bubble on a solid surface Phys. Rev. E 56 6745 (1997)] thus raising the question as to whether cavitation damage is due to (micro)jets or imploding (hemispherical) shock waves. Finally flow through a Venturi tube generates a stream of bubbles which also emit subnanosecond flashes of light [F. B. Peterson and T. P. Anderson Phys. Fluids 10 874 (1967)]. Luminescence from an isolated trapped bubble in water seems to work well with any noble gas whereas luminescence from cavitating flows and surface bubbles is quite dependent on xenon [argon bubbles appear to give no light at all]. The width of the SL flash [Gompf et al. Phys. Rev. Lett. 79 1405 (1997) Hiller et al. Phys. Rev. Lett. 80 1090 (1998)] has been found to be independent of wavelength suggesting that light is emitted from a new high energy phase of matter?probably a cold dense nano?plasma. The key unknowns of SL are the size and temperature of the hot spot from which the light is emitted. Experiments aimed at measuring these quantities will be discussed.

Enthalpy Diffusion in Multicomponent Flows  

SciTech Connect (OSTI)

The conclusions of this paper are: (1) Enthalpy diffusion preserves the second law. (2) Euler solvers will not produce correct temperatures in mixing regions. (3) Navier-Stokes solvers will only produce correct temperatures if q{sub d} is included. (4) Errors from neglecting enthalpy diffusion are most severe when differences in molecular weights are large. (5) In addition to temperature, enthalpy diffusion affects density, dilatation and other fields in subtle ways. (6) Reacting flow simulations that neglect the term are a dubious proposition. (7) Turbulence models for RANS and LES closures should preserve consistency between energy and species diffusion.

Air/water and vapor/freon were utilized to scale and simulate annular two-phase flow for high pressure steam/water conditions. A unique vapor/liquid Freon loop was built to obtain the high pressure data. The results were compared with two correlations available in the open literature. The Ishii and Mishima dimensionless group was able to scale the data remarkably well even for vapor/liquid Freon. However, the correlation needs to be adjusted for high Weber numbers of the gas phase.

DYNAMIC MODELING STRATEGY FOR FLOW REGIME TRANSITION IN GAS-LIQUID TWO-PHASE FLOWS  

SciTech Connect (OSTI)

In modeling gas-liquid two-phase flows, the concept of flow regime has been used to characterize the global interfacial structure of the flows. Nearly all constitutive relations that provide closures to the interfacial transfers in two-phase flow models, such as the two-fluid model, are often flow regime dependent. Currently, the determination of the flow regimes is primarily based on flow regime maps or transition criteria, which are developed for steady-state, fully-developed flows and widely applied in nuclear reactor system safety analysis codes, such as RELAP5. As two-phase flows are observed to be dynamic in nature (fully-developed two-phase flows generally do not exist in real applications), it is of importance to model the flow regime transition dynamically for more accurate predictions of two-phase flows. The present work aims to develop a dynamic modeling strategy for determining flow regimes in gas-liquid two-phase flows through the introduction of interfacial area transport equations (IATEs) within the framework of a two-fluid model. The IATE is a transport equation that models the interfacial area concentration by considering the creation and destruction of the interfacial area, such as the fluid particle (bubble or liquid droplet) disintegration, boiling and evaporation; and fluid particle coalescence and condensation, respectively. For the flow regimes beyond bubbly flows, a two-group IATE has been proposed, in which bubbles are divided into two groups based on their size and shape (which are correlated), namely small bubbles and large bubbles. A preliminary approach to dynamically identifying the flow regimes is provided, in which discriminators are based on the predicted information, such as the void fraction and interfacial area concentration of small bubble and large bubble groups. This method is expected to be applied to computer codes to improve their predictive capabilities of gas-liquid two-phase flows, in particular for the applications in which flow regime transition occurs.

Heat flow on the southern Colorado Plateau  

Science Journals Connector (OSTI)

Heat-flow data from the study area in the southern Colorado Plateau indicate a pattern of local anomalies having relatively high heat flow superimposed on a regional, intermediate heat-flow setting. While many of the conventional heat-flow data are relatively shallow and may be perturbed by groundwater circulation, bottom-hole temperature data from two relatively deep petroleum exploration drill holes near the southern plateau periphery yield intermediate heat-flow estimates. The mean heat flow within the volcanically active Jemez zone does not appear to be significantly greater than the mean heat flow for the remainder of the study area. This is due to the presence of high heat-flow values outside the Jemez zone. Sites with relatively high heat flow located towards the plateau interior and away from recent volcanic activity of the Jemez zone may reflect magma intrusion and/or groundwater movement along crustal zones of weakness associated with Laramide deformation (monoclines). The heat-flow data are consistent with coal maturation data, which suggest that any regional post-Cretaceous thermal events that may be associated with the southern Plateau boundary have been initiated relatively recently, or are occurring at relatively great depths, or are occurring south of the Jemez lineament.

Proximal bodies in hypersonic flow  

SciTech Connect (OSTI)

Hypersonic flows involving two or more bodies travelling in close proximity to one another are encountered in several important situations, both natural and man-made. The present work seeks to investigate one aspect of the resulting flow problem by exploring the forces experienced by a secondary body when it is within the domain of influence of a primary body travelling at hypersonic speeds. An analytical methodology based on the blast wave analogy is developed and used to predict the secondary force coefficients for simple geometries in both two and three dimensions. When the secondary body is entirely inside the primary shocked region, the nature of the lateral force coefficient is found to depend strongly on the relative size of the two bodies. For two spheres, the methodology predicts that the secondary body will experience an exclusively attractive lateral force if the secondary diameter is larger than one-sixth the primary diameter. The analytical results are compared with those from numerical simulations and reasonable agreement is observed if an appropriate normalization for the lateral displacement is used. Results from a series of experiments in the T5 hypervelocity shock tunnel are also presented and compared with perfect-gas numerical simulations, with good agreement. A new force-measurement technique for short-duration hypersonic facilities, enabling the experimental simulation of the proximal bodies problem, is described. This technique provides two independent means of measurement, and the agreement observed between the two gives a further degree of confidence in the results obtained.

Effect of a co?flowing annular outer flow on the flow and acoustics in a porous tube.  

Science Journals Connector (OSTI)

One of the most important aspects of flow in a gas turbine combustor is the cooling airflow introduced through the combustor liner. The co?flowing annular cooling air affects the flow and the acoustic field of the main combustor. A generic study is in progress to study the effect of a co?flowing annular outer flow on the flow and acoustics in a porous tube. This work is an idealization of the actual gas turbine combustor flow. The results generated here will be used to validate the computational codes currently being used by the gas turbine industry to calculate these flow fields. In the present experimental work a 6?in.?diam tube made out of perforated sheet is located coaxially in an 8?in.?diam outer tube. Airflows in the inner perforated tube as well as in the annular space between the two tubes. Detailed measurements of the turbulence structure using hot wire anemometry and of the acoustic field using microphonetransducers are being made. Effects of parameters such as porosity of the tube relative areas of annular space and cross section of inner tube and flow Reynolds number on the turbulence quantities and the acoustic field will be reported.

CFD analysis of laminar oscillating flows  

SciTech Connect (OSTI)

This paper describes a numerical simulations of oscillating flow in a constricted duct and compares the results with experimental and theoretical data. The numerical simulations were performed using the computational fluid dynamics (CFD) code CFX4.2. The numerical model simulates an experimental oscillating flow facility that was designed to test the properties and characteristics of oscillating flow in tapered ducts, also known as jet pumps. Jet pumps are useful devices in thermoacoustic machinery because they produce a secondary pressure that can counteract an unwanted effect called streaming, and significantly enhance engine efficiency. The simulations revealed that CFX could accurately model velocity, shear stress and pressure variations in laminar oscillating flow. The numerical results were compared to experimental data and theoretical predictions with varying success. The least accurate numerical results were obtained when laminar flow approached transition to turbulent flow.

Assessment of Historic Trend in Mobility and Energy Use in India Transportation Sector Using Bottom-up Approach  

SciTech Connect (OSTI)

Transportation mobility in India has increased significantly in the past decades. From 1970 to 2000, motorized mobility (passenger-km) has risen by 888%, compared with an 88% population growth (Singh,2006). This contributed to many energy and environmental issues, and an energy strategy incorporates efficiency improvement and other measures needs to be designed. Unfortunately, existing energy data do not provide information on driving forces behind energy use and sometime show large inconsistencies. Many previous studies address only a single transportation mode such as passenger road travel; did not include comprehensive data collection or analysis has yet been done, or lack detail on energy demand by each mode and fuel mix. The current study will fill a considerable gap in current efforts, develop a data base on all transport modes including passenger air and water, and freight in order to facilitate the development of energy scenarios and assess significance of technology potential in a global climate change model. An extensive literature review and data collection has been done to establish the database with breakdown of mobility, intensity, distance, and fuel mix of all transportation modes. Energy consumption was estimated and compared with aggregated transport consumption reported in IEA India transportation energy data. Different scenarios were estimated based on different assumptions on freight road mobility. Based on the bottom-up analysis, we estimated that the energy consumption from 1990 to 2000 increased at an annual growth rate of 7% for the mid-range road freight growth case and 12% for the high road freight growth case corresponding to the scenarios in mobility, while the IEA data only shows a 1.7% growth rate in those years.

Theoretical uncertainty of orifice flow measurement  

SciTech Connect (OSTI)

Orifice meters are the most common meters used for fluid flow measurement, especially for measuring hydrocarbons. Meters are rugged, mechanically simple, and well suited for field use under extreme weather conditions. Because of their long history of use and dominance in the fluid flow measurement, their designs, installation requirements, and equations for flow rate calculation have been standardized by different organizations in the United States and internationally. These standards provide the guideline for the users to achieve accurate flow measurement. and minimize measurement uncertainty. This paper discusses different factors that contribute to the measurement inaccuracy and provide an awareness to minimize or eliminate these errors. Many factors which influence the overall measurement uncertainty are associated with the orifice meter application. Major contributors to measurement uncertainty include the predictability of flow profile, fluid properties at flowing condition, precision of empirical equation for discharge coefficient, manufacturing tolerances in meter components, and the uncertainty associated with secondary devices monitoring the static line pressure, differential pressure across the orifice plate, flowing temperature, etc. Major factors contributing to the measurement uncertainty for a thin, concentric, square-edged orifice flowmeter are as follows: (a) Tolerances in prediction of coefficient of discharge, (b) Predictability in defining the physical properties of the flowing fluid, (c) Fluid flow condition, (d) Construction tolerances in meter components, (e) Uncertainty of secondary devices/instrumentation, and (f) Data reduction and computation. Different factors under each of the above areas are discussed with precautionary measures and installation procedures to minimize or eliminate measurement uncertainty.

The Boussinesq approximation in rapidly rotating flows  

E-Print Network [OSTI]

In the classical formulation of the Boussinesq approximation centrifugal buoyancy effects related to differential rotation, as well as strong vortices in the flow, are neglected. However, these may play an important role in rapidly rotating flows, such as in astrophysical and geophysical applications, and also in turbulent convection. We here provide a straightforward approach resulting in a Boussinesq-type approximation that consistently accounts for centrifugal effects. We further compare our new approach to the classical one in fluid flows confined between two differentially heated and rotating cylinders. The results justify the need of using the proposed approximation in rapidly rotating flows.

Flow visualisation in inclined louvered fins  

SciTech Connect (OSTI)

In this study the flow within an interrupted fin design, the inclined louvered fin, is investigated experimentally through visualisation. The inclined louvered fin is a hybrid of the offset strip fin and standard louvered fin, aimed at improved performance at low Reynolds numbers for compact heat exchangers. The flow behaviour is studied in six geometrically different configurations over a range of Reynolds numbers and quantified using the concept of 'fin angle alignment factor'. The transition from steady laminar to unsteady flow was studied in detail. The fin geometry had a very large impact on the transitional flow behaviour, especially on vortex shedding. (author)

Measurement of thermodynamics using gradient flow  

E-Print Network [OSTI]

We analyze bulk thermodynamics and correlation functions of the energy-momentum tensor in pure Yang-Mills gauge theory using the energy-momentum tensor defined by the gradient flow and small flow time expansion. Our results on thermodynamic observables are consistent with those obtained by the conventional integral method. The analysis of the correlation function of total energy supports the energy conservation. It is also addressed that these analyses with gradient flow require less statistics compared with the previous methods. All these results suggest that the energy-momentum tensor can be successfully defined and observed on the lattice with moderate numerical costs with the gradient flow.

Combustion synthesis continuous flow reactor  

DOE Patents [OSTI]

The present invention is a reactor for combustion synthesis of inorganic powders. The reactor includes a reaction vessel having a length and a first end and a second end. The reaction vessel further has a solution inlet and a carrier gas inlet. The reactor further has a heater for heating both the solution and the carrier gas. In a preferred embodiment, the reaction vessel is heated and the solution is in contact with the heated reaction vessel. It is further preferred that the reaction vessel be cylindrical and that the carrier gas is introduced tangentially into the reaction vessel so that the solution flows helically along the interior wall of the reaction vessel. As the solution evaporates and combustion produces inorganic material powder, the carrier gas entrains the powder and carries it out of the reactor.

Thermodynamics with Continuous Information Flow  

Science Journals Connector (OSTI)

We provide a unified thermodynamic formalism describing information transfers in autonomous as well as nonautonomous systems described by stochastic thermodynamics. We demonstrate how information is continuously generated in an auxiliary system and then transferred to a relevant system that can utilize it to fuel otherwise impossible processes. Indeed, while the joint system satisfies the second law, the entropy balance for the relevant system is modified by an information term related to the mutual information rate between the two systems. We show that many important results previously derived for nonautonomous Maxwell demons can be recovered from our formalism and use a cycle decomposition to analyze the continuous information flow in autonomous systems operating at a steady state. A model system is used to illustrate our findings.

Renormalization flows in complex networks  

Science Journals Connector (OSTI)

Complex networks have acquired a great popularity in recent years, since the graph representation of many natural, social, and technological systems is often very helpful to characterize and model their phenomenology. Additionally, the mathematical tools of statistical physics have proven to be particularly suitable for studying and understanding complex networks. Nevertheless, an important obstacle to this theoretical approach is still represented by the difficulties to draw parallelisms between network science and more traditional aspects of statistical physics. In this paper, we explore the relation between complex networks and a well known topic of statistical physics: renormalization. A general method to analyze renormalization flows of complex networks is introduced. The method can be applied to study any suitable renormalization transformation. Finite-size scaling can be performed on computer-generated networks in order to classify them in universality classes. We also present applications of the method on real networks.

Flow-induced vibration: 1992  

SciTech Connect (OSTI)

A joint program on flow-induced vibration (FIV) as established in July 1988 between Taiwan Power Company (Taipower or TPC) and ANL. The main objectives of the program are to provide a technology transfer program on FIV for Taipower staff and to assist Taipower with various aspects of FIV including evaluation of reports and proposals, review of designs, resolution of design issues, recommendation for design modifications, and selected research studies. During the first two years, the following tasks were accomplished: A technology transfer program on FIV was completed and key Taipower staff members were prepared to handle future problems in the subject area. The modified component cooling water (CCW) heat exchangers were assessed and the basis for a license from the Taiwan Atomic Energy Council (AEC) was established. The seismic reanalysis of Chin Shan spent-fuel racks was assessed and a report was submitted to the Taiwan AEC. Fluid/structure interaction activities were coordinated and provided a list of potential bidders for a fluid transient project and related publications and a recommendation for purchasing technical data on fluid coupling. Flow-induced vibration of tube arrays was reviewed and the needs of Taipower in the area of fluid/structure interaction were identified as were the procedures necessary for Taipower to accomplish its goals. A computer program, ARRAY, was established to compute the added-mass matrices for tube arrays. Taipower expressed interest in extending the joint program so that ANL could provide continuing assistance. The program was extended for several years (May 1, 1991, to June 30, 1994). Work from May 1, 1991, through June 30, 1992, summarized in this report, included technology transfer, assessment of sensing line and valve vibrations, literature survey, and tests on motion-dependent fluid forces acting on tube arrays in crossflow.

Site-Scale Saturated Zone Flow Model  

SciTech Connect (OSTI)

The purpose of this model report is to document the components of the site-scale saturated-zone flow model at Yucca Mountain, Nevada, in accordance with administrative procedure (AP)-SIII.lOQ, ''Models''. This report provides validation and confidence in the flow model that was developed for site recommendation (SR) and will be used to provide flow fields in support of the Total Systems Performance Assessment (TSPA) for the License Application. The output from this report provides the flow model used in the ''Site-Scale Saturated Zone Transport'', MDL-NBS-HS-000010 Rev 01 (BSC 2003 [162419]). The Site-Scale Saturated Zone Transport model then provides output to the SZ Transport Abstraction Model (BSC 2003 [164870]). In particular, the output from the SZ site-scale flow model is used to simulate the groundwater flow pathways and radionuclide transport to the accessible environment for use in the TSPA calculations. Since the development and calibration of the saturated-zone flow model, more data have been gathered for use in model validation and confidence building, including new water-level data from Nye County wells, single- and multiple-well hydraulic testing data, and new hydrochemistry data. In addition, a new hydrogeologic framework model (HFM), which incorporates Nye County wells lithology, also provides geologic data for corroboration and confidence in the flow model. The intended use of this work is to provide a flow model that generates flow fields to simulate radionuclide transport in saturated porous rock and alluvium under natural or forced gradient flow conditions. The flow model simulations are completed using the three-dimensional (3-D), finite-element, flow, heat, and transport computer code, FEHM Version (V) 2.20 (software tracking number (STN): 10086-2.20-00; LANL 2003 [161725]). Concurrently, process-level transport model and methodology for calculating radionuclide transport in the saturated zone at Yucca Mountain using FEHM V 2.20 are being carried out in the model report, ''Site-Scale Saturated Zone Transport'', MDL-NBS-HS-000010 Rev 01 (BSC 2003 [162419]). The velocity fields are calculated by the flow model, described herein, independent of the transport processes, and are then used as inputs to the transport model. Justification for this abstraction is presented in the model report, ''Saturated Zone Flow and Transport Model Abstraction'', MDL-NBS-HS-000021 (BSC 2003 [164870]).

General single phase wellbore flow model  

SciTech Connect (OSTI)

A general wellbore flow model, which incorporates not only frictional, accelerational and gravitational pressure drops, but also the pressure drop caused by inflow, is presented in this report. The new wellbore model is readily applicable to any wellbore perforation patterns and well completions, and can be easily incorporated in reservoir simulators or analytical reservoir inflow models. Three dimensionless numbers, the accelerational to frictional pressure gradient ratio R{sub af}, the gravitational to frictional pressure gradient ratio R{sub gf}, and the inflow-directional to accelerational pressure gradient ratio R{sub da}, have been introduced to quantitatively describe the relative importance of different pressure gradient components. For fluid flow in a production well, it is expected that there may exist up to three different regions of the wellbore: the laminar flow region, the partially-developed turbulent flow region, and the fully-developed turbulent flow region. The laminar flow region is located near the well toe, the partially-turbulent flow region lies in the middle of the wellbore, while the fully-developed turbulent flow region is at the downstream end or the heel of the wellbore. Length of each region depends on fluid properties, wellbore geometry and flow rate. As the distance from the well toe increases, flow rate in the wellbore increases and the ratios R{sub af} and R{sub da} decrease. Consequently accelerational and inflow-directional pressure drops have the greatest impact in the toe region of the wellbore. Near the well heel the local wellbore flow rate becomes large and close to the total well production rate, here R{sub af} and R{sub da} are small, therefore, both the accelerational and inflow-directional pressure drops can be neglected.

Liquid Crystal Microfluidics for Tunable Flow Shaping  

Science Journals Connector (OSTI)

We explore the flow of a nematic liquid crystal in microfluidic channels with a rectangular cross section through experiments and numerical modeling. The flow profile and the liquid crystal orientational profile show three distinct regimes of weak, medium, and strong flow as the driving pressure is varied. These are identified by comparing polarizing optical microscopy experiments and numerical solutions of the nematofluidic equations of motion. The relative stability of the regimes is related to the de Gennes characteristic shear-flow lengths e1 and e2, together with the channels aspect ratio w/d. Finally, we show that the liquid crystalline microfluidic flow can be fully steered from left to right of a simple microchannel by applying transverse temperature gradients.

Rapidity Dependence of Elliptic Flow at RHIC  

E-Print Network [OSTI]

The measured elliptic flow (v2) of identified particles as a function of pT and centrality at RHIC suggests the created medium in Au+Au collisions achieves early local thermal equilibrium that is followed by hydrodynamic expansion. It is not known if the eta dependence on v2 is a general feature of elliptic flow or reflects other changes in the particle spectra in going from mid-rapidity to foward rapidities. The BRAHMS experiment provides a unique capability compared to the other RHIC experiments to measure v2 for identified particles over a wide rapidity range. From Run 4 Au+Au collision at sqrt{s_{NN}} = 200GeV, identified elliptic flow is studied using the BRAHMS spectrometers, which cover 0flow and to measure the pT-integrated flow for charged hadrons.

DOE Patents [OSTI]

A filter for clarifying carbonaceous liquids containing finely divided solid particles of, for instance, unreacted coal, ash and other solids discharged from a coal liquefaction process is presented. The filter includes two passageways separated by a porous filter medium. In one preferred embodiment the filter medium is of tubular shape to form the first passageway and is enclosed within an outer housing to form the second passageway within the annulus. An electrode disposed in the first passageway, for instance along the tube axis, is connected to a source of high voltage for establishing an electric field between the electrode and the filter medium. Slurry feed flows through the first passageway tangentially to the surfaces of the filter medium and the electrode. Particles from the feed slurry are attracted to the electrode within the first passageway to prevent plugging of the porous filter medium while carbonaceous liquid filters into the second passageway for withdrawal. Concentrated slurry is discharged from the first passageway at an end opposite to the feed slurry inlet. Means are also provided for the addition of diluent and a surfactant into the slurry to control relative permittivity and the electrophoretic mobility of the particles.

Constraints on flow regimes in wide-aperture fractures  

SciTech Connect (OSTI)

In recent years, significant advances have been made in our understanding of the complex flow processes in individual fractures, aided by flow visualization experiments and conceptual modeling efforts. These advances have led to the recognition of several flow regimes in individual fractures subjected to different initial and boundary conditions. Of these, the most important regimes are film flow, rivulet flow, and sliding of droplets. The existence of such significantly dissimilar flow regimes has been a major hindrance in the development of self-consistent conceptual models of flow for single fractures that encompass all the flow regimes. The objective of this study is to delineate the existence of the different flow regimes in individual fractures. For steady-state flow conditions, we developed physical constraints on the different flow regimes that satisfy minimum energy configurations, which enabled us to segregate the wide range of fracture transmissivity (volumetric flow rate per fracture width) into several flow regimes. These are, in increasing order of flow rate, flow of adsorbed films, flow of sliding drops, rivulet flow, stable film flow, and unstable (turbulent) film flow. The scope of this study is limited to wide-aperture fractures with the flow on the opposing sides of fracture being independent.

Geothermal Two-Phase Wellbore Flow: Pressure Drop Correlations and Flow Pattern Transitions  

SciTech Connect (OSTI)

In this paper we present some basic concepts of two-phase flow and review the Orkiszewski (1967) correlations which have been suggested by various investigators to perform well for geothermal wellbore flow situations. We also present a flow regime map based on the transition criteria used by Orkiszewski (1967) and show that most geothermal wells flow under slug flow regime. We have rearranged bubble- to slug-flow transition criterion used by Orkiszewski (1967) to show that the transition depends on the dimensionless pipe diameter number in addition to dimensionless liquid and gas velocity numbers. Our aim is also to identify what research may lead to improvements in two-phase pressure drop calculations for geothermal wellbore flow.

Annular flow control safety valve  

SciTech Connect (OSTI)

A tubular housing having an inner tubular member forms an inner passageway inside of the inner member and an outer passageway between the inner member and the housing. The housing has valve openings leading from the outer passageway to the exterior of the housing and a tubular valve closure member telescopically moves on the interior of the housing. First means move the valve closure member in an upper direction for closing the openings and at least one actuating piston is telescopically movable within and has its longitudinal axis in the wall of the housing and engages the valve closure member. The piston is in communication with a hydraulic passageway adapted to extend to the well surface for actuating the closure member in a direction to open the valve openings. The closure member is positioned whereby upward flow through the outer passageway acts on the closure member to close the valve opening. At least one lockout piston telescopically moves within the housing and is actuated from the surface and is engageable with holding means in the housing for providing a hydraulic lockout for the valve. Shear means may be provided between the lockout piston and the housing for controlling the hydraulic lockout. A single seal is provided between the closure member and the housing and is positioned below the opening and exposed to the pressure on both sides when the valve is opened. Preferably the actuating pistons are connected to the valve closure member but the hydraulic lockout pistons engage but are unconnected to the valve closure member.

A new tracer flow-test system has been developed for in situ characterization of geologic formations. This report describes two sets of test equipment: one portable and one for testing in deep formations. Equations are derived for in situ detector calibration, raw data reduction, and flow logging. Data analysis techniques are presented for computing porosity and permeability in unconfined isotropic media, and porosity, permeability and fracture characteristics in media with confined or unconfined two-dimensional flow. The effects of tracer pulse spreading due to divergence, dispersion, and porous formations are also included.

Redox Flow Batteries: An Engineering Perspective  

SciTech Connect (OSTI)

Redox flow batteries are well suited to provide modular and scalable energy storage systems for a wide range of energy storage applications. In this paper, we review the development of redox flow battery technology including recent advances in new redox active materials and systems. We discuss cost, performance, and reliability metrics that are critical for deployment of large flow battery systems. The technology, while relatively young, has the potential for significant improvement through reduced materials costs, improved energy and power efficiency, and significant reduction in the overall system cost.

Grand valley irrigation return flow case study  

SciTech Connect (OSTI)

Irrigation water supply is furnished annually to about 71,500 acres of land in the Grand Valley of western Colorado. Return flows from that irrigation contribute about 780,000 tpy of salt to the Colorado River, causing an increase of 77 mg/l in the salinity concentration at Imperial Dam. A case study of water quality in this region is focused on: water quality data for irrigation and return flows/ identification of regulations that affect irrigation and return flows/ and a proposed program for controlling salinity levels.

Multiphase Flow and Cavern Abandonment in Salt  

SciTech Connect (OSTI)

This report will explore the hypothesis that an underground cavity in gassy salt will eventually be gas filled as is observed on a small scale in some naturally occurring salt inclusions. First, a summary is presented on what is known about gas occurrences, flow mechanisms, and cavern behavior after abandonment. Then, background information is synthesized into theory on how gas can fill a cavern and simultaneously displace cavern fluids into the surrounding salt. Lastly, two-phase (gas and brine) flow visualization experiments are presented that demonstrate some of the associated flow mechanisms and support the theory and hypothesis that a cavity in salt can become gas filled after plugging and abandonment

Mass Dependence of Directed Collective Flow  

SciTech Connect (OSTI)

Sidewards directed fragment flow has been extracted for {sup 84}Kr+{sup 197}Au collisions at {ital E}/{ital A}=200 MeV, using techniques that are free of reaction plane dispersion. The fragment flow per nucleon increases with mass, following a thermal or coalescencelike behavior, and attains roughly constant limiting values at 4{le}{ital A}{le}12. Comparisons of the impact parameter dependences of the measured coalescence-invariant proton flow to Boltzmann-Uehling-Uhlenbeck calculations clearly favor a momentum dependent nuclear mean field. {copyright} {ital 1996 The American Physical Society.}

An investigation into flow regimes for two-phase helium flow  

SciTech Connect (OSTI)

The Tevatron accelerator at Fermilab incorporates long two-phase helium passages. During magnet design, the generalized flow map of Baker was used to predict homogeneous flow. Longer than expected magnet time constants led to this investigation. The importance of predicting the flow regime has been amplified with the advent of non-horizontal accelerator designs. A test setup was constructed at Fermilab to investigate two-phase helium flow regimes for conditions practical in accelerator designs. The setup consisted of a standard Tevatron satellite refrigerator, subcooling dewar, heater, 35 m long transfer line, and a specialized end box. A knife blade on the midplane of the transfer line diverted the flow from the upper and lower halves of the pipe to separate vessels in the end box. The amount of liquid above and below the plane was measured at various total mass flow rates and liquid percentages. The results show that stratified flow occurs at much higher liquid percentages than predicted by the Baker diagram (several orders of magnitude). We were not able to produce high enough steady state flows to find a boundary to a homogenous flow regime. Stratified flow occurred over all practical conditions for long accelerator magnet systems.

Saturation of elliptic flow and shear viscosity  

E-Print Network [OSTI]

Effect of shear viscosity on elliptic flow is studied in causal dissipative hydrodynamics in 2+1 dimensions. Elliptic flow is reduced in viscous dynamics. Causal evolution of minimally viscous fluid ($\\eta/s$=0.08), can explain the PHENIX data on elliptic flow in 16-23% Au+Au collisions up to $p_T\\approx$3.6 GeV. In contrast, ideal hydrodynamics, can explain the same data only up to $p_T\\approx$1.5 GeV. $p_T$ spectra of identified particles are also better explained in minimally viscous fluid than in ideal dynamics. However, saturation of elliptic flow at large $p_T$ is not reproduced.

Flow mapping for an ESS horizontal target  

SciTech Connect (OSTI)

In the target of the European spallation neutron source (ESS), the beam line is horizontal and the mercury is fully forced by a pump in a parallel channel geometry. The top front of the assembly is a hemicylindrical wall, where the beam enters and is thus called a window. The main body is partitioned by a horizontal separation plate into the upper and the lower flow channels. The target liquid flows in the lower channel to the window region, turns there, and flows out in the upper channel. A thermal-hydraulic study is under way to investigate the general behavior of the flow in this configuration. The present experimental work is the first step of an effort to validate computer codes. The model used in this investigation is two-dimensional and uses water.

Two-phase flow in horizontal wells  

SciTech Connect (OSTI)

Flow in horizontal wells and two-phase flow interaction with the reservoir were investigated experimentally and theoretically. Two-phase flow behavior has been recognized as one of the most important problems in production engineering. The authors designed and constructed a new test facility suitable for acquiring data on the relationship between pressure drop and liquid holdup along the well and fluid influx from the reservoir. For the theoretical work, an initial model was proposed to describe the flow behavior in a horizontal well configuration. The model uses the inflow-performance-relationship (IPR) approach and empirical correlations or mechanistic models for wellbore hydraulics. Although good agreement was found between the model and experimental data, a new IPR apart from the extension of Darcy`s law must be investigated extensively to aid in the proper design of horizontal wells.

Uncertainty quantification for porous media flows  

SciTech Connect (OSTI)

Uncertainty quantification is an increasingly important aspect of many areas of computational science, where the challenge is to make reliable predictions about the performance of complex physical systems in the absence of complete or reliable data. Predicting flows of oil and water through oil reservoirs is an example of a complex system where accuracy in prediction is needed primarily for financial reasons. Simulation of fluid flow in oil reservoirs is usually carried out using large commercially written finite difference simulators solving conservation equations describing the multi-phase flow through the porous reservoir rocks. This paper examines a Bayesian Framework for uncertainty quantification in porous media flows that uses a stochastic sampling algorithm to generate models that match observed data. Machine learning algorithms are used to speed up the identification of regions in parameter space where good matches to observed data can be found.

Pressure balanced drag turbine mass flow meter  

DOE Patents [OSTI]

The density of the fluid flowing through a tubular member may be measured by a device comprising a rotor assembly suspended within the tubular member, a fluid bearing medium for the rotor assembly shaft, independent fluid flow lines to each bearing chamber, and a scheme for detection of any difference between the upstream and downstream bearing fluid pressures. The rotor assembly reacts to fluid flow both by rotation and axial displacement; therefore concurrent measurements may be made of the velocity of blade rotation and also bearing pressure changes, where the pressure changes may be equated to the fluid momentum flux imparted to the rotor blades. From these parameters the flow velocity and density of the fluid may be deduced.

Certification of flow monitors for utility boilers  

SciTech Connect (OSTI)

The use of CEMS for measuring opacity, SO{sub 2}, NO{sub x}, CO{sub 2}, and O{sub 2} concentration was well proven prior to implementing the Part 75 CEMS program. However, the use of continuous flue gas flow monitoring devices is a relatively new instrumental technique. Limited operating data for flow monitors were available and little or no certification relative accuracy data were available prior to the Summer of 1993. However, because of the Part 75 requirements, utility companies contracted with CEMS vendors to install, start-up and certify flow monitors on Phase 1 and Phase 2 units. This paper presents the certification history of three different types of flow monitors (ultrasonic, pressure differential ({Delta}p) and thermal) installed at various utilities in the US. The data and experience was obtained from approximately 100 Phase 1 CEMS units and 200 Phase 1 CEMS units.

GENI Project: ORNL is developing an electromagnet-based, amplifier-like device that will allow for complete control over the flow of power within the electric grid. To date, complete control of power flow within the grid has been prohibitively expensive. ORNLs controller could provide a reliable, cost-effective solution to this problem. The team is combining two types of pre-existing technologies to assist in flow control, culminating in a prototype iron-based magnetic amplifier. Ordinarily, such a device would require expensive superconductive wire, but the magnetic iron core of ORNLs device could serve as a low-cost alternative that is equally adept at regulating power flow.

On the Geodesic Nature of Wegner's Flow  

E-Print Network [OSTI]

Wegner's method of flow equations offers a useful tool for diagonalizing a given Hamiltonian and is widely used in various branches of quantum physics. Here, generalizing this method, a condition is derived, under which the corresponding flow of a quantum state becomes geodesic in a submanifold of the projective Hilbert space, independently of specific initial conditions. This implies the geometric optimality of the present method as an algorithm of generating stationary states. The result is illustrated by analyzing some physical examples.

The solution indicates that the transonic state can be solved as an elliptic boundary value problem, as is done in the numerical code FLOW [Guazzotto et al., Phys. Plasmas 11, 604 (2004)]. Moreover, the presence of a hyperbolic region does not necessarily imply the presence of a discontinuity or any other singularity of the solution.

Data flow machine for data driven computing  

DOE Patents [OSTI]

A data flow computer which of computing is disclosed which utilizes a data driven processor node architecture. The apparatus in a preferred embodiment includes a plurality of First-In-First-Out (FIFO) registers, a plurality of related data flow memories, and a processor. The processor makes the necessary calculations and includes a control unit to generate signals to enable the appropriate FIFO register receiving the result. In a particular embodiment, there are three FIFO registers per node: an input FIFO register to receive input information form an outside source and provide it to the data flow memories; an output FIFO register to provide output information from the processor to an outside recipient; and an internal FIFO register to provide information from the processor back to the data flow memories. The data flow memories are comprised of four commonly addressed memories. A parameter memory holds the A and B parameters used in the calculations; an opcode memory holds the instruction; a target memory holds the output address; and a tag memory contains status bits for each parameter. One status bit indicates whether the corresponding parameter is in the parameter memory and one status but to indicate whether the stored information in the corresponding data parameter is to be reused. The tag memory outputs a "fire" signal (signal R VALID) when all of the necessary information has been stored in the data flow memories, and thus when the instruction is ready to be fired to the processor.

Evaluation of low flow characteristics of the Vermont Yankee plant  

SciTech Connect (OSTI)

Boiling water reactor (BWR) core flow instrumentation inaccuracies under low-flow conditions have been the subject of both reactor vendor and regulatory communications in response to incidents of the reported core flow being less than the flow corresponding to the natural-circulation line on the power flow map. During single recirculation loop operation, low-flow conditions exist in the idle recirculation loop, and these flow inaccuracies can affect the usefulness of the reported core flow. Accurate core flow indications are needed above 25% power to administer fuel thermal limits and comply with restrictions associated with the potential for thermal-hydraulic instability. While the natural-circulation line on the power flow map is recognized to be a nominal estimate of the flow expected at and near natural-circulation conditions, the boundaries of the stability regions are associated with conditions assumed in safety analyses performed to demonstrate compliance with general design criteria 10 and 12.

Slurry fired heater cold-flow modelling  

SciTech Connect (OSTI)

This report summarizes the experimental and theoretical work leading to the scale-up of the SRC-I Demonstration Plant slurry fired heater. The scale-up involved a theoretical model using empirical relations in the derivation, and employed variables such as flow conditions, liquid viscosity, and slug frequency. Such variables have been shown to affect the heat transfer characteristics ofthe system. The model assumes that, if all other variables remain constant, the heat transfer coefficient can be scaled up proportional to D/sup -2/3/ (D = inside diameter of the fired heater tube). All flow conditions, liquid viscosities, and pipe inclinations relevant to the demonstration plant have indicated a slug flow regime in the slurry fired heater. The annular and stratified flow regimes should be avoided to minimize the potential for excessive pipe erosion and to decrease temperature gradients along the pipe cross section leading to coking and thermal stresses, respectively. Cold-flow studies in 3- and 6.75-in.-inside-diameter (ID) pipes were conducted to determine the effect of scale-up on flow regime, slug frequency, and slug dimensions. The developed model assumes that conduction heat transfer occurs through the liquid film surrounding the gas slug and laminar convective heat transfer to the liquid slug. A weighted average of these two heat transfer mechanisms gives a value for the average pipe heat transfer coefficient. The cold-flow work showed a decrease in the observed slug frequency between the 3- and 6.75-ID pipes. Data on the ratio of gas to liquid slug length in the 6.75-in. pipe are not yet complete, but are expected to yield generally lower values than those obtained in the 3-in. pipe; this will probably affect the scale-up to demonstration plant conditions. 5 references, 15 figures, 7 tables.

Flow Battery System Design for Manufacturability.  

SciTech Connect (OSTI)

Flow battery energy storage systems can support renewable energy generation and increase energy efficiency. But, presently, the costs of flow battery energy storage systems can be a significant barrier for large-scale market penetration. For cost- effective systems to be produced, it is critical to optimize the selection of materials and components simultaneously with the adherence to requirements and manufacturing processes to allow these batteries and their manufacturers to succeed in the market by reducing costs to consumers. This report analyzes performance, safety, and testing requirements derived from applicable regulations as well as commercial and military standards that would apply to a flow battery energy storage system. System components of a zinc-bromine flow battery energy storage system, including the batteries, inverters, and control and monitoring system, are discussed relative to manufacturing. The issues addressed include costs and component availability and lead times. A service and support model including setup, maintenance and transportation is outlined, along with a description of the safety-related features of the example flow battery energy storage system to promote regulatory and environmental, safety, and health compliance in anticipation of scale manufacturing.

Dissipative flows of 2D foams  

E-Print Network [OSTI]

We analyze the flow of a liquid foam between two plates separated by a gap of the order of the bubble size (2D foam). We concentrate on the salient features of the flow that are induced by the presence, in an otherwise monodisperse foam, of a single large bubble whose size is one order of magnitude larger than the average size. We describe a model suited for numerical simulations of flows of 2D foams made up of a large number of bubbles. The numerical results are successfully compared to analytical predictions based on scaling arguments and on continuum medium approximations. When the foam is pushed inside the cell at a controlled rate, two basically different regimes occur: a plug flow is observed at low flux whereas, above a threshold, the large bubble migrates faster than the mean flow. The detailed characterization of the relative velocity of the large bubble is the essential aim of the present paper. The relative velocity values, predicted both from numerical and from analytical calculations that are discussed here in great detail, are found to be in fair agreement with experimental results.

Flow heterogeneity following global no-flow ischemia in isolated rabbit heart  

SciTech Connect (OSTI)

The purpose of this study was to evaluate flow heterogeneity and impaired reflow during reperfusion following 60 min global no-flow ischemia in the isolated rabbit heart. Radiolabeled microspheres were used to measure relative flow in small left ventricular (LV) segments in five ischemia + reperfused hearts and in five non-ischemic controls. Although variable in the post-ischemic hearts, flow heterogeneity was increased relative to pre-ischemia for the whole LV (0.92 plus or minus 0.41 vs. 0.37 plus or minus 0.07, P < 0.05) as well as the subendocardium (Endo) and subepicardium (Epi) considered separately (endo: 1.28 plus or minus 0.74 vs. 0.30 plus or minus 0.09; epi: 0.69 plus or minus 0.22 vs. 0.38 plus or minus 0.08; P < 0.05 for both comparisons) during early reperfusion. There were also segments with abnormally reduced reflow. The number of segments with abnormally reduced reflow increased as flow heterogeneity increased. Abnormally reduced reflow indicates that regional ischemia can persist despite restoration of normal global flow. In addition, the relationship between regional and global flow is altered and venous outflow is derived from regions with continued perfusion and not the whole LV. These observations emphasize the need to quantify regional reflow during reperfusion following sustained no-flow ischemia in the isolated rabbit heart.

The in situ permeable flow sensor: A device for measuring groundwater flow velocity  

SciTech Connect (OSTI)

A new technology called the In Situ Permeable Flow Sensor has been developed at Sandia National Laboratories. These sensors use a thermal perturbation technique to directly measure the direction and magnitude of the full three dimensional groundwater flow velocity vector in unconsolidated, saturated, porous media. The velocity measured is an average value characteristic of an approximately 1 cubic meter volume of the subsurface. During a test at the Savannah River Site in South Carolina, two flow sensors were deployed in a confined aquifer in close proximity to a well which was screened over the entire vertical extent of the aquifer and the well was pumped at four different pumping rates. In this situation horizontal flow which is radially directed toward the pumping well is expected. The flow sensors measured horizontal flow which was directed toward the pumping well, within the uncertainty in the measurements. The observed magnitude of the horizontal component of the flow velocity increased linearly with pumping rate, as predicted by theoretical considerations. The measured horizontal component of the flow velocity differed from the predicted flow velocity, which was calculated with the assumptions that the hydraulic properties of the aquifer were radially homogeneous and isotropic, by less than a factor of two. Drawdown data obtained from other wells near the pumping well during the pump test indicate that the hydraulic properties of the aquifer are probably not radially homogeneous but the effect of the inhomogeneity on the flow velocity field around the pumping well was not modeled because the degree and distribution of the inhomogeneity are unknown. Grain size analysis of core samples from wells in the area were used to estimate the vertical distribution of hydraulic conductivity.

Flowing Liquid Crystal Simulating the Schwarzschild Metric  

E-Print Network [OSTI]

We show how to simulate the equatorial section of the Schwarzschild metric through a flowing liquid crystal in its nematic phase. Inside a liquid crystal in the nematic phase, a traveling light ray feels an effective metric, whose properties are linked to perpendicular and parallel refractive indexes, $n_o$ e $n_e$ respectively, of the rod-like molecule of the liquid crystal. As these indexes depend on the scalar order parameter of the liquid crystal, the Beris-Edwards hydrodynamic theory is used to connect the order parameter with the velocity of a liquid crystal flow at each point. This way we calculate a radial velocity profile that simulates the equatorial section of the Schwarzschild metric, in the region outside of Schwarzschild's radius, in the nematic phase of the liquid crystal. In our model, the higher flow velocity can be of the order of some meters per second.

Source flow chemical laser cavity performance  

SciTech Connect (OSTI)

The flow field in chemical optical cavities with source flow injectors is investigated. The 2-D coupled gasdynamics, chemical-vibrational-rotational kinetics, and multiline laser radiation equations are solved by using a stable implicit numerical method. The flow field-resonator interaction through the gain-intensity relations is calculated by linearization of the kinetics equations and application of an interative procedure. Calculated small signal gain distributions, closed cavity power variation with mode width, and intracavity spectral content are shown to be in close agreement with experimental measurements. A parametric study has also been conducted, and the potential improvements in performance are illustrated. The results indicate a strong dependency of optical power potential on fluid mechanical interactions with the injector cavity hardware.

Lattice Boltzmann model for traffic flow  

Science Journals Connector (OSTI)

Mesoscopic models for traffic flows are usually difficult to be employed because of the appearance of integro-differential terms in the models. In this work, a lattice Boltzmann model for traffic flow is introduced on the basis of the existing kinetics models by using the Bhatnagar-Gross-Krook-type approximation interaction term in the Boltzmann equation and discretizing it in time and phase space. The so-obtained model is simple while the relevant parameters are physically meaningful. Together with its discrete feature, the model can be easily used to investigate numerically the behavior of traffic flows. In consequence, the macroscopic dynamics of the model is derived using the Taylor and Chapman-Enskog expansions. For validating the model, numerical simulations are conducted under the periodic boundary conditions. It is found that the model could reasonably reproduce the fundamental diagram. Moreover, certain interesting physical phenomena can be captured by the model, such as the metastability and stop-and-go phenomena.

Theoretical and numerical studies on the flow multiplicity phenomenon for gassolids two-phase flows in CFB risers  

Science Journals Connector (OSTI)

The dependence of the fully-developed flow profiles on the inlet flow conditions for gassolids two-phase flows, i.e. the flow multiplicity phenomenon, in circulating fluidized bed (CFB) risers was proposed and discussed in this article. The flow multiplicity phenomenon for gassolids two-phase flows was first proved mathematically based on the conservation equations of mass and momentum. Then the CFD model using EulerianEulerian approach with k? turbulence model for each phase was further adopted to analyze the details of this flow multiplicity phenomenon. It is theoretically and numerically revealed that for gassolids two-phase flows, the flow profiles in the fully-developed region are always dominated by the flow profiles at the inlet. The solids concentration profile is closely coupled with the velocity profile, and the inlet solids concentration and velocity profiles can largely influence the fully-developed concentration and velocity profiles.

Integral curves of this flow turn out to be in natural bijection with geodesics on the Riemannian supermanifold. We also construct the corresponding exponential map and generalize the well-known faithful linearization of isometries to Riemannian supermanifolds.

Rebalancing electrolytes in redox flow battery systems  

DOE Patents [OSTI]

Embodiments of redox flow battery rebalancing systems include a system for reacting an unbalanced flow battery electrolyte with a rebalance electrolyte in a first reaction cell. In some embodiments, the rebalance electrolyte may contain ferrous iron (Fe.sup.2+) which may be oxidized to ferric iron (Fe.sup.3+) in the first reaction cell. The reducing ability of the rebalance reactant may be restored in a second rebalance cell that is configured to reduce the ferric iron in the rebalance electrolyte back into ferrous iron through a reaction with metallic iron.

Proper time regulator and renormalization group flow  

Science Journals Connector (OSTI)

We consider some applications of the renormalization group flow equations obtained by resorting to a specific class of proper time regulators. Within this class a particular limit that corresponds to a sharpening of the effective width of the regulator is investigated and a procedure to analytically implement this limit on the flow equations is shown. We focus on the critical exponents determination for the O(N) symmetric scalar theory in three dimensions. The large N limit and some perturbative features in four dimensions are also analyzed. In all problems examined the results are optimized when the mentioned limit of the proper time regulator is taken.

System for measuring multiphase flow using multiple pressure differentials  

DOE Patents [OSTI]

An improved method and system for measuring a multi-phase flow in a pressure flow meter. An extended throat venturi is used and pressure of the multi-phase flow is measured at three or more positions in the venturi, which define two or more pressure differentials in the flow conduit. The differential pressures are then used to calculate the mass flow of the gas phase, the total mass flow, and the liquid phase. The system for determining the mass flow of the high void fraction fluid flow and the gas flow includes taking into account a pressure drop experienced by the gas phase due to work performed by the gas phase in accelerating the liquid phase.

Colloidal particle deposition in turbulent flow  

SciTech Connect (OSTI)

A theoretical analysis is presented which describes the initial deposition of monodispersed spherical colloidal particles from a steady fully developed turbulent flow onto conduit walls. When the net particle-conduit electrical interaction potential is attractive, particle deposition is shown to be often governed by turbulent hydrodynamics. When the net particle-conduit electrical interaction potential possess a repulsive maximum, particle deposition to first order is uniform and depends solely on electrical interaction effects. The developed theoretical model specialized to orifice deposition with the use of Harwell Flow3D turbulence modelling software qualitatively described the deposition of 0.5 {mu}m silica particles onto glass orifices from an aqueous suspension. The effect of the electrical double layer on the rate of colloidal particle deposition in laminar flow has been described by Spielman and Friedlander (1), Dahneke (2), Bowen et al. (3) and Bowen and Epstein (4). This article describes the extension of their work to colloidal particle deposition under steady fully developed turbulent flow conditions. This article also reports the results of orifice particle deposition experiments which were conducted to qualitatively investigate the developed theoretical model.
