Advancing Material Models for Automotive Forming Simulations  

SciTech Connect

Simulations in automotive industry need more advanced material models to achieve highly reliable forming and springback predictions. Conventional material models implemented in the FEM-simulation models are not capable to describe the plastic material behaviour during monotonic strain paths with sufficient accuracy. Recently, ESI and Corus co-operate on the implementation of an advanced material model in the FEM-code PAMSTAMP 2G. This applies to the strain hardening model, the influence of strain rate, and the description of the yield locus in these models. A subsequent challenge is the description of the material after a change of strain path.The use of advanced high strength steels in the automotive industry requires a description of plastic material behaviour of multiphase steels. The simplest variant is dual phase steel consisting of a ferritic and a martensitic phase. Multiphase materials also contain a bainitic phase in addition to the ferritic and martensitic phase. More physical descriptions of strain hardening than simple fitted Ludwik/Nadai curves are necessary.Methods to predict plastic behaviour of single-phase materials use a simple dislocation interaction model based on the formed cells structures only. At Corus, a new method is proposed to predict plastic behaviour of multiphase materials have to take hard phases into account, which deform less easily. The resulting deformation gradients create geometrically necessary dislocations. Additional micro-structural information such as morphology and size of hard phase particles or grains is necessary to derive the strain hardening models for this type of materials.Measurements available from the Numisheet benchmarks allow these models to be validated. At Corus, additional measured values are available from cross-die tests. This laboratory test can attain critical deformations by large variations in blank size and processing conditions. The tests are a powerful tool in optimising forming simulations prior to larger scale industrial validation.

New Automotive Air Conditioning System Simulation Tool Developed in MATLAB/Simulink  

SciTech Connect

Further improvements in vehicle fuel efficiency require accurate evaluation of the vehicle's transient total power requirement. When operated, the air conditioning (A/C) system is the largest auxiliary load on a vehicle; therefore, accurate evaluation of the load it places on the vehicle's engine and/or energy storage system is especially important. Vehicle simulation software, such as 'Autonomie,' has been used by OEMs to evaluate vehicles' energy performance. A transient A/C simulation tool incorporated into vehicle simulation models would also provide a tool for developing more efficient A/C systems through a thorough consideration of the transient A/C system performance. The dynamic system simulation software Matlab/Simulink was used to develop new and more efficient vehicle energy system controls. The various modeling methods used for the new simulation tool are described in detail. Comparison with measured data is provided to demonstrate the validity of the model.

Advanced computational simulation for design and manufacturing of lightweight material components for automotive applications  

SciTech Connect

Computational vehicle models for the analysis of lightweight material performance in automobiles have been developed through collaboration between Oak Ridge National Laboratory, the National Highway Transportation Safety Administration, and George Washington University. The vehicle models have been verified against experimental data obtained from vehicle collisions. The crashed vehicles were analyzed, and the main impact energy dissipation mechanisms were identified and characterized. Important structural parts were extracted and digitized and directly compared with simulation results. High-performance computing played a key role in the model development because it allowed for rapid computational simulations and model modifications. The deformation of the computational model shows a very good agreement with the experiments. This report documents the modifications made to the computational model and relates them to the observations and findings on the test vehicle. Procedural guidelines are also provided that the authors believe need to be followed to create realistic models of passenger vehicles that could be used to evaluate the performance of lightweight materials in automotive structural components.

Component-in-the-Loop Component-in-the-Loop To reduce development time and introduce technologies faster to the market, many companies have been turning more and more to Model Based Design. In Model Based Design, the development process centers around a system model, from requirements capture and design to implementation and test. Engineers can skip over a generation of system design processes on the basis of hand coding and use graphical models to design, analyze, and implement the software that determines machine performance and behavior. One of the steps of Model Based Design is Component-in-the-Loop. Engineers in Argonne National Laboratory's Center for Transportation Research have developed Component-in-the-Loop (CIL) systems and processes to evaluate the impact of vehicle energy management schemes, component control unit parameters, powertrain configurations on fuel and/or electrical consumption. Argonne has used the CIL for several components, including:

Automotive Stirling summary and overview  

SciTech Connect

Government-funded studies for adapting the Stirling engine to an automotive application started in 1971. The initial studies were to reduce exhaust emissions and were later broadened to include fuel economy and alternate fuels. With the passage of the Automotive Propulsion Research and Development Act of 1978, the studies matured into the current Automotive Stirling Engine (ASE) Program. After eight years of development effort, the accomplishments of the ASE Program are reviewed to assess the outlook for program success at its scheduled completion in September 1987. One important goal of the ASE program is the transfer of Stirling engine technology to the USA. The technology transfer to the ASE Program team members has been accomplished. To expand the transfer in the USA, various activities have been initiated to make available the developed automotive Stirling engine technology to other US industries, including nonautomotive.

Instructors’ Support of Student Autonomy in an Introductory Physics Course  

Science Journals Connector (OSTI)

The role of autonomy in the student experience in a large-enrollment undergraduate introductory physics course was studied from a self-determination theory perspective. A correlational study investigated whether certain aspects of the student experience correlated with how autonomy supportive (versus controlling) students perceived their instructors to be. An autonomy-supportive instructor acknowledges students’ perspectives and feelings and provides students with information and opportunities for choice while minimizing external pressures (e.g., incentives or deadlines). It was found that the degree to which students perceived their instructors as autonomy supportive was positively correlated with student interest and enjoyment in learning physics (?=0.31***) and negatively correlated with student anxiety about taking physics (?=?0.23**). It was also positively correlated with how autonomous (versus controlled) students’ reasons for studying physics became over the duration of the course (i.e., studying physics more because they wanted to versus had to; ?=0.24***). This change in autonomous reasons for studying physics was in turn positively correlated with student performance in the course (?=0.17*). Additionally, the degree to which students perceived their instructors as autonomy supportive was directly correlated with performance for those students entering the course with relatively autonomous reasons for studying physics (?=0.25**). In summary, students who perceived their instructors as more autonomy supportive tended to have a more favorable motivational, affective, and performance experience in the course. The findings of the present study are consistent with experimental studies in other contexts that argue for autonomy-supportive instructor behaviors as the cause of a more favorable student experience.

Biodiesel properties and automotive system compatibility issues  

Science Journals Connector (OSTI)

Abstract Acceptability of biodiesel by automotive sector is limited due to some of its adverse properties such as cold flow properties, oxidation stability and corrosiveness with automotive fuel system materials. Adverse cold flow properties of biodiesel lead to the problem of plugging and gumming of filters and injectors. There is a concern about the poor oxidation stability of biodiesel, which results in the formation of sediments and gums causing problem in the engine fuel injection system. Biodiesel reacts with automotive fuel system materials adversely resulting in corrosion of metals and degradation of elastomers. Beside these adverse issues, biodiesel possesses incredible inherent lubricity. This article aims to review the adverse biodiesel properties like cold flow properties, oxidation stability; corrosive and acidic nature resulting in non-compatibility with automotive fuel system materials. It also discusses the excellent lubrication behaviour of biodiesel and its positive impact. An effort has been made to present the review of 145 research papers along with the sharing of our some in-house experimental results. Additive treatment with biodiesel has been found to be suitable for improving the low temperature properties and oxidation stability. Certain metallic and elastomeric components have been reported as compatible/non-compatible with biodiesel. Although attempts have already been made by some researchers on the adverse properties of biodiesel but the scope is rather limited to the properties alone than correlating the same with automotive materials compatibility.

Mod I automotive Stirling engine mechanical development  

SciTech Connect

The Mod I Stirling engine was the first automotive Stirling engine designed specifically for automotive application. Testing of these engines has revealed several deficiencies in engine mechanical integrity which have been corrected by redesign or upgrade. The main deficiencies uncovered during the Mod I program lie in the combustion, auxiliary, main seal, and heater head areas. This paper will address each of the major area deficiencies in detail, and describe the corrective actions taken as they apply to the Mod I and the next Stirling-engine design, the Upgraded Mod I (a redesign to incorporate new materials for cost/weight reduction and improved performance).

Past experiences with automotive external combustion engines  

SciTech Connect

GMR (General Motors Research Laboratories, now GM R and D Center) has a history of improving the internal combustion engine, especially as it relates to automotive use. During the quarter century from 1950--75, considerable effort was devoted to evaluating alternative powerplants based on thermodynamic cycles different from those on which the established spark-ignition and diesel engines are founded. Two of these, the steam engine and the Stirling engine, incorporated external combustion. Research on those two alternatives is reviewed. Both were judged to fall short of current needs for commercial success as prime movers for conventional automotive vehicles.

Passive Two-Phase Cooling of Automotive Power Electronics: Preprint  

SciTech Connect

Experiments were conducted to evaluate the use of a passive two-phase cooling strategy as a means of cooling automotive power electronics. The proposed cooling approach utilizes an indirect cooling configuration to alleviate some reliability concerns and to allow the use of conventional power modules. An inverter-scale proof-of-concept cooling system was fabricated, and tests were conducted using the refrigerants hydrofluoroolefin HFO-1234yf and hydrofluorocarbon HFC-245fa. Results demonstrated that the system can dissipate at least 3.5 kW of heat with 250 cm3 of HFC-245fa. An advanced evaporator design that incorporates features to improve performance and reduce size was conceived. Simulation results indicate its thermal resistance can be 37% to 48% lower than automotive dual side cooled power modules. Tests were also conducted to measure the thermal performance of two air-cooled condensers--plain and rifled finned tube designs. The results combined with some analysis were then used to estimate the required condenser size per operating conditions and maximum allowable system (i.e., vapor and liquid) temperatures.

Automotive Stirling engine: Mod II design report  

SciTech Connect

The design of an automotive Stirling engine that achieves the superior fuel economy potential of the Stirling cycle is described. As the culmination of a 9-yr development program, this engine, designated the Mod II, also nullifies arguments that Stirling engines are heavy, expensive, unreliable, and demonstrate poor performance. Installed in a General Motors 1985 Chevrolet Celebrity car, this engine has a predicted combined fuel economy on unleaded gasoline of 17.5 km/L (41 mi/gal) - a value 50% above the current vehicle fleet average. The Mod II Stirling engine is a four-cylinder V-drive design with a single crankshaft. The engine is also equipped with all the controls and auxiliaries necessary for automotive operation. 35 figs.

Regional variations of days of autonomy for solar energy applications  

SciTech Connect

A problem faced by designers of stand-alone solar installations is the sizing of the collector area and storage capacity. From a curve of the minimum possible insolation over any period of days for a given site, a functional relationship between the collector-area and storage-capacity that provides a 0% probability of not meeting load (PNML) can be derived. This permits evaluating the regional variations in days-of-autonomy required to provide 100% reliability. Such variations are shown for Texas based on recent insolation data.

Oxidation of automotive primary reference fuels at elevated pressures  

SciTech Connect

Automotive engine knock limits the maximum operating compression ratio and ultimate thermodynamic efficiency of spark-ignition (SI) engines. In compression-ignition (CI) or diesel cycle engines, the premixed burn phase, which occurs shortly after injection, determines the time it takes for autoignition to occur. In order to improve engine efficiency and to recommend more efficient, cleaner-burning alternative fuels, they must understand the chemical kinetic processes that lead to autoignition in both SI and CI engines. These engines burn large molecular-weight blended fuels, a class to which the primary reference fuels (PRF) n-heptane and iso-octane belong. In this study, experiments were performed under engine like conditions in a high-pressure flow reactor using both the pure PRF fuels and their mixtures in the temperature range 550-880 K and 12.5 atm pressure. These experiments not only provide information on the reactivity of each fuel but also identify the major intermediate products formed during the oxidation process. A detailed chemical kinetic mechanism is used to simulate these experiments, and comparisons of experimentally measured and model predicted profiles for O{sub 2}, CO, CO{sub 2}, H{sub 2}O and temperature rise are presented. Intermediates identified in the flow reactor are compared with those present in the computations, and the kinetic pathways leading to their formation are discussed. In addition, autoignition delay times measured in a shock tube over the temperature range 690-1220 K and at 40 atm pressure were simulated. Good agreement between experiment and simulation was obtained for both the pure fuels and their mixtures. Finally, quantitative values of major intermediates measured in the exhaust gas of a cooperative fuels research engine operating under motored engine conditions are presented together with those predicted by the detailed model.

Automotive Control Systems: For Engine, Driveline, and Vehicle  

Science Journals Connector (OSTI)

Many engineers, working in the field of automotive control systems and mechatronics, as well as lecturing at technical universities, will welcome this book. It gives a broad insight view of the latest automotive technologies in use which have been adopted over a long period of time from research activities at universities and in industry. About twenty years ago the microcomputer started to revolutionize the possibility of introducing intelligence in systems, for example in the form of advanced control algorithms. By chance, this incredible evolution coincided with increasing environmental demands to reduce pollution and oil consumption and to contribute one of the major tools to meet those demands. This may have been one of the reasons why the automotive industry was rather early in introducing the new technique. However, it would have been interesting if the book had given a short historic review. In fact the authors do not rule out that the modern four-stroke engine in a car may work as an air-cleaning filter, and after going through the part describing the lambda-control together with the catalytic conversion, it is hard to argue against it, at least when the vehicle is running at constant speed. Reading this book you realize that the times are long gone when you could use a screwdriver and feeler gauge to adjust the ignition of your car engine. The subtitle of the book is engine, driveline and vehicle and the book is also divided in that logical order. In the first part, after describing the thermodynamic cycles of different engine types, spark ignited and diesel, the basic engine operations are presented and the reader is given a theoretical insight into what can be done to enhance the performance of the engine. If you have forgotten the basic laws of thermodynamics there is an appendix to recapitulate (however, there is no explanation of the word stoichiometric in case you are not familiar with that). You will also find information on the efficiency of different fuels as well as the efficiency of engines derived from crankshaft motions and thermodynamics. The next chapter describes how the derived models of engine management are used for advanced engine control. The chapter also presents simulation results as well as measurement results. What is especially interesting to read about is how effectively the catalytic conversion works together with lambda-control at stoichiometric combustion of the spark-ignited engine. This is thoroughly explained in the text but a curious reader will not get any information about problems or if there are ongoing activities with emission reduction concerning its competitor, the diesel engine. It is understandable that the book concentrates on the most popular automotive engines but an interested reader might miss that there is nothing in the book that covers the state-of-the-art spark-ignited two-stroke engine. The second part of the book covers the driveline, that is, the parts that transfer the torque of the engine to the wheels. The initial chapters cover the derivation of general models of driveline, basically by applying Newton's second law of motion. Those models are then applied to the modern truck for simulation of the dynamical behaviour. After validation, the appropriate simulation model is used in designing a control system for a transmission that does not need a clutch for shifting gears. Consequently, this part of the book is very interesting since, most likely, one of the authors has worked in close cooperation with the Swedish truck manufacturer Scania. He describes the development behind this unique and patented transmission system. The third and last part of the book deals with the vehicle itself. Initially, geometrical vehicle models of different complexity, the two-track and single-track, are described. They are used to derive the forces acting on the wheels due to road friction and road profile, as well as the driver's input, such as steering and braking. The book claims to have 291 illustrations. The third part of the book, however, could have benefited from more

Washing treatment of automotive shredder residue (ASR)  

Science Journals Connector (OSTI)

Abstract Worldwide, the amount of end-of-life vehicles (ELVs) reaches 50 million units per year. Once the ELV has been processed, it may then be shredded and sorted to recover valuable metals that are recycled in iron and steelmaking processes. The residual fraction, called automotive shredder residue (ASR), represents 25% of the ELV and is usually landfilled. In order to deal with the leachable fraction of ASR that poses a potential threat to the environment, a washing treatment before landfilling was applied. To assess the potential for full-scale application of washing treatment, tests were carried out in different conditions (L/S = 3 and 5 L/kgTS; t = 3 and 6 h). Moreover, to understand whether the grain size of waste could affect the washing efficiency, the treatment was applied to ground (<4 mm) and not-ground samples. The findings obtained revealed that, on average, washing treatment achieved removal rates of more than 60% for dissolved organic carbon (DOC), chemical oxygen demand (COD) and total Kjeldahl nitrogen (TKN). With regard to metals and chlorides, sulphates and fluoride leachable fraction, a removal efficiency of approximately 60% was obtained, as confirmed also by EC values. The comparison between the results for ground and not-ground samples did not highlight significant differences.

Paint robotics—improving automotive painting performance  

Science Journals Connector (OSTI)

Robotic painting has achieved increased popularity in recent years, due to the flexibility and enhanced performance with such systems. There is a clear trend among major automobile makers to change from hard to flexible automation, and, in that respect, paint robotics is becoming increasingly more important for future paint shop design. New programming tools offer operators and paint engineers better possibility to program and maintain robot systems. With the introduction of the laser, a powerful tool is now available for real-time, in-line control of film build and the related paint process. With the additional advances in robotic-based quality inspection systems, such as a robot-mounted quality inspection camera systems, automotive manufacturers now have the possibility to document and store literally all paint quality data for a multitude of purposes related to process control. Combining these technologies offers a glimpse of a future where true closed-loop process control and quality monitoring can be used to diminish significantly the variation in paint application systems, improve flexibility, quality, and reduce operational costs, while at the same time reduce the complexity of robotic painting systems.

Downsizing assessment of automotive Stirling engines  

SciTech Connect

A 67 kW (90 hp) Stirling engine design, sized for use in a 1984 1440 kg (3170 lb) automobile has been serving as the focal point for developing automotive Stirling engine technology under a current DOE/NASA R and D program. Since recent trends are towards lighter vehicles, an assessment was made of the appicability of the Stirling technology being developed for smaller, lower power engines. Using both the Philips scaling laws and a Lewis Research Center (Lewis) Stirling engine performance code, dimensional and performance characteristics were determined for a 26 kW (35 hp) and a 37 kW (50 hp) engine for use in a nominal 907 kg (2000 lb) vehicle. Key engine elements were sized and stressed and mechanical layouts were made to ensure mechanical fit and integrity of the engines. Fuel economy estimates indicated that the Stirling engine would maintain a 30 to 45 percent fuel economy advantage over comparable spark ignition and diesel powered vehicles in the 1984 time period. In order to maintain the performance advantage, particular attention must be paid to the Stirling engine mechanical losses and, although evaluated in this report, the cold start penalties.

Coated glass in the automotive industry  

Science Journals Connector (OSTI)

Inorganic coatings on glasses have reached the level where they will certainly be applied in the automotive industry in order to solve such glazing problems as heat load, heat loss, glare, UV adsorption, disturbed reflections, electromagnetic influence and thermal insulation. Their widespread use will depend on optimising the solution to problems of solar control and heatable glasses while the glass is also capable of the other functions required of it, thus justifying the relatively high cost that is predicted. There remain unsolved problems in optical limits and colour matching. When these are solved solar control glasses are likely to give real advantages in terms of air conditioning and comfort, and heatable glasses will be used in association with electrical power for demisting and deicing. Particular attention is being directed to a class of infrared reflecting and heatable glasses, obtained by selectively coating transparent plastic films that are embedded or bonded in laminated or tempered glasses. Fabricating this type of glasses has mainly been useful for two reasons: (I) to develop versatile techniques to make solar control IR reflecting and heatable glasses for all kinds and dimensions of vehicle glazing; and (2) to assess whether these glasses are really feasible alternatives to directly coated glasses. This paper describes results of some solar control experiments in Fiat cars: to ascertain the actual internal temperature differences found when glazing vehicles with the absorbing and reflecting IR glasses currently available; and to obtain results with a similar purpose using heatable glasses. There is also discussion of how the glasses could be used in glazing all or parts of a car's windows / especially addressing problems of glare. Suggestions are made of the directions of this research in the future.

AISI/DOE Technology Roadmap Program: Improved Surface Quality of Exposed Automotive Sheet Steels  

SciTech Connect

Surface quality of sheet steels is an important economic and technical issue for applications such as critical automotive surfaces. This project was therefore initiated to develop a more quantitative methodology for measuring surface imperfections, and to assess their response to forming and painting, particularly with respect to their visibility or invisibility after painting. The objectives were met, and included evaluation of a variety of imperfections present on commercial sheet surfaces or simulated using methods developed in the laboratory. The results are expected to have significant implications with respect to the methodology for assessing surface imperfections, development of quantitative criteria for surface inspection, and understanding and improving key painting process characteristics that influence the perceived quality of sheet steel surfaces.

The Automotive Stirling Engine (ASE) Development Program was established to enable research and development of alternate propulsion systems. The program was awarded to Mechanical Technology Incorporated (MTI) for the purpose of developing an automotive Stirling engine, and transferring Stirling-engine technology to the United States. MTI has fabricated and tested four Mod I engines that have accumulated over 1900 test hours to date. The engines evaluated in the test cell have achieved an average of 34.5% efficiency at their maximum efficiency point (2000 rpm), and have developed an average maximum output power (power available to the drive train) level of 54.4 kW (73.2 bhp). All engines are still operating, and are being used to develop components and control strategy for the Upgraded Mod I engine design (predicted to increase maximum power output and efficiency while reducing total engine system weight).

Hydrogen storage systems for automotive applications: project StorHy  

Science Journals Connector (OSTI)

Around two thirds of world's oil usage is associated with transportation with road vehicles consuming around 40%. Also, transportation accounts for around 25% of greenhouse emissions worldwide, with around 90% coming from road vehicles. This situation is further complicated by the fact that oil reserves are running out. For this reason, the automotive industry supported by relevant governing bodies is rapidly exploring alternative propulsion solutions (such as hybrid, electric and hydrogen powered vehicle technologies). This paper presents the main objectives and progressive findings of an EU funded research project titled 'StorHy â?? Hydrogen Storage Systems for Automotive Applications'. This research project was conducted in partnership between a number of participating organisations under the auspice of the EU Thematic Priority 6 program titled 'Sustainable development, global change and ecosystems'. The integrated project, StorHy, aims to develop robust, safe and efficient on-board vehicle hydrogen storage systems suitable for use in hydrogen-fuelled fuel cell or internal combustion engine vehicles. Research work covering the whole spectrum of hydrogen storage technologies (compressed gas, cryogenic liquid and solid materials) is carried out with a focus on automotive applications. The aim is to develop economically and environmentally attractive solutions for all three storage technologies.

The influence of surface topography on the forming friction of automotive aluminum sheet  

SciTech Connect

Interest in utilizing aluminum alloys in automobiles has increased in recent years as a result of the desire to lower automobile weight and, consequently, increase fuel economy. While aluminum alloy use in cast parts has increased, outer body panel applications are still being investigated. The industry is interested in improving the formability of these sheet alloys by a combination of alloy design and processing. A different avenue of improving the formability of these alloys may be through patterning of the sheet surface. Surface patterns hold the lubricant during the forming process, with a resulting decrease in the sheet-die surface contact. While it has been speculated that an optimum surface pattern would consist of discrete cavities, detailed investigation into the reduction of forming friction by utilizing discrete patterns is lacking. A series of discrete patterns were investigated to determine the dependence of the forming friction of automotive aluminum alloys on pattern lubricant carrying capacity and on material strength. Automotive aluminum alloys used in outer body panel applications were rolled on experimental rolls that had been prepared with a variety of discrete patterns. All patterns for each alloy were characterized before and after testing both optically and, to determine pattern lubricant capacity, using three dimensional laser profilometry. A draw bead simulation (DBS) friction tester was designed and fabricated to determine the forming friction of the patterned sheets. Tensile testing and frictionless DBS testing were performed to ascertain the material properties of each sheet. The most striking result of this work was the inversely linear dependence of forming friction on the lubricant carrying capacity of the discrete patterns.

How training and experience affect the benefits of autonomy in a dirty-bomb experiment  

SciTech Connect

A dirty-bomb experiment conducted at the INL is used to evaluate the effectiveness and suitability of three different modes of robot control. The experiment uses three distinct user groups to understand how participants’ background and training affect the way in which they use and benefit from autonomy. The results show that the target mode, which involves automated mapping and plume tracing together with a point and click tasking tool, provides the best performance for each group. This is true for objective performance such as source detection and localization accuracy as well as subjective measures such as perceived workload, frustration and preference. The best overall performance is achieved by the Explosive Ordinance Disposal group which has experience in both robot teleoperation and dirty bomb response. The user group that benefits least from autonomy is the Nuclear Engineers that have no experience with either robot operation or dirty bomb response. The group that benefits most from autonomy is the Weapons of Mass Destruction Civil Response Team that has extensive experience related to the task, but no robot training.

Power Modulation Investigation for High Temperature (175-200 degrees Celcius) Automotive Application  

SciTech Connect

Hybrid electric vehicles were re-introduced in the late 1990s after a century dominated by purely internal combustion powered engines[1]. Automotive players, such as GM, Ford, DaimlerChrysler, Honda, and Toyota, together with major energy producers, such as BPAmoco, were the major force in the development of hybrid electric vehicles. Most notable was the development by Toyota of its Prius, which was launched in Japan in 1997 and worldwide in 2001. The shift to hybrids was driven by the fact that the sheer volume of vehicles on the road had begun to tax the ability of the environment to withstand the pollution of the internal combustion engine and the ability of the fossil fuel industry to produce a sufficient amount of refined gasoline. In addition, the number of vehicles was anticipated to rise exponentially with the increasing affluence of China and India. Over the last fifteen years, major advances have been made in all the technologies essential to hybrid vehicle success, including batteries, motors, power control and conditioning electronics, regenerative braking, and power sources, including fuel cells. Current hybrid electric vehicles are gasoline internal combustion--electric motor hybrids. These hybrid electric vehicles range from micro-hybrids, where a stop/start system cuts the engine while the vehicle is stopped, and mild hybrids where the stop/start system is supplemented by regenerative braking and power assist, to full hybrids where the combustion motor is optimized for electric power production, and there is full electric drive and full regenerative braking. PSA Peugeot Citroen estimates the increased energy efficiency will range from 3-6% for the micro-hybrids to 15-25% for the full hybrids.[2] Gasoline-electric hybrids are preferred in US because they permit long distance travel with low emissions and high gasoline mileage, while still using the existing refueling infrastructure. One of the most critical areas in which technology has been advancing has been the development of electronics that can operate in the high temperature environments present in hybrid vehicles. The temperatures under the hood for a gasoline-electric hybrid vehicle are comparable to those for traditional internal combustion engines. This is known to be a difficult environment with respect to commercial-grade electronics, as there are surface and ambient temperatures ranging from 125 C to 175 C. In addition, some hybrid drive electronics are placed in even harsher environments, such as on or near the brakes, where temperatures can reach 250 C. Furthermore, number of temperature cycles experienced by electronics in a hybrid vehicle is different from that experienced in a traditional vehicle. A traditional internal combustion vehicle will have the engine running for longer periods, whereas a mild or micro-hybrid engine will experience many more starts and stops.[3] This means that hybrid automotive electronics will undergo more cycles of a potential wider temperature cycle than standard automotive electronics, which in turn see temperature cycles of 2 to 3 times the magnitude of the {Delta}T = 50 C-75 C experienced by commercial-grade electronics. This study will discuss the effects of these harsh environments on the failure mechanisms and ultimate reliability of electronic systems developed for gasoline-electric hybrid vehicles. In addition, it will suggest technologies and components that can reasonably be expected to perform well in these environments. Finally, it will suggest areas where further research is needed or desirable. Areas for further research will be highlighted in bold, italic type. It should be noted that the first area where further research is desirable is in developing a clearer understanding of the actual hybrid automotive electronics environment and how to simulate it through accelerated testing, thus: Developing specific mission profiles and accelerated testing protocols for the underhood environment for hybrid cars, as has previously been done for gasoline-powered vehicles, is an important area for further st

Route-dependent operation of automotive fuel cell systems  

Science Journals Connector (OSTI)

Information on energy demand and traversal times along segments of a route is used to operate a fuel cell of an automotive drive in order to minimise fuel consumption. The buffering capacity of a battery is exploited to proactively leave the fuel cell idle or run it as close as possible to its maximum efficiency power level. Additionally, recuperation energy is buffered. Shortest paths in so-called power graphs correspond to approximately optimal fuel cell operation along a given route. In principle, minimum consumption routes can be computed in the same way. The approach targets planning rather than control.

Laboratory scale studies on gaseous emissions generated by the incineration of an artificial automotive shredder residue presenting a critical composition  

Science Journals Connector (OSTI)

Car manufacturers must eliminate automotive shredder residues (ASR). Two ways of incineration are of interest: at 850°C in municipal waste incinerators or at higher temperatures, above 1100°C in cement plants. These processes reduce the mass and the volume of waste to be disposed of in landfills and energy recovery might be possible. Regulations govern the emission of gaseous effluents to control environmental risk. To determine gaseous effluents from a pilot sacle or an industrial incineration plant, an artificial ASR was made by mixing three representative organic polymers present in the real ASR, namely polyvinylchloride, polyurethane and rubber. This mixture was incinerated at 850 and 1100°C in laboratory experiments and the analyses of the principal gaseous effluents such as carbon oxides, nitrogen oxides, volatile organic compounds, hydrochloric and hydrocyanic acids and sulphur compounds are presented and discussed. Lastly, in order to simulate artificial ASR behaviour, the composition of the combustion gases at equilibrium was calculated using a Gibbs energy minimisation code.

Modular PM Motor Drives for Automotive Traction Applications  

SciTech Connect

This paper presents modular permanent magnet (PM) motor drives for automotive traction applications. A partially modularized drive system consisting of a single PM motor and multiple inverters is described. The motor has multiple three-phase stator winding sets and each winding set is driven with a separate three-phase inverter module. A truly modularized inverter and motor configuration based on an axial-gap PM motor is then introduced, in which identical PM motor modules are mounted on a common shaft and each motor module is powered by a separate inverter module. The advantages of the modular approach for both inverter and motor include: (1) power rating scalability--one design meets different power requirements by simply stacking an adequate number of modules, thus avoiding redesigning and reducing the development cost, (2) increased fault tolerance, and (3) easy repairing. A prototype was constructed by using two inverters and an axial-gap PM motor with two sets of three-phase stat or windings, and it is used to assist the diesel engine in a hybrid electric vehicle converted from a Chevrolet Suburban. The effect of different pulse-width-modulation strategies for both motoring and regenerative modes on current control is analyzed. Torque and regenerative control algorithms are implemented with a digital signal processor. Analytical and initial testing results are included in the paper.

The main objective of this manuscript is to present an analysis of the catalytic gasification of ASR for the generation of high-purity hydrogen in a lab-scale fixed-bed downdraft gasifier using 15 wt.% NiO/Al2O3 catalysts at 760–900 K. In the catalytic gasification process, reduction of Ni(II) catalyst into Ni(0) has been confirmed through XANES spectra and consequently EXAFS data shows that the central Ni atoms have Ni–O and Ni–Ni bonds with bond distances of 2.03 ± 0.05 and 2.46 ± 0.05 Ĺ, respectively. ASR is partially oxidized and ultimately converts into hydrogen rich syngas (CO and H2) and increases of the reaction temperature are favored the generation of hydrogen with decomposition of the CO. As well, approximately 220 kg h?1 of ASR would be catalytically gasified at 760–900 K and 46.2 atm with the reactor volume 0.27 m3 to obtain approximately 3.42 × 105 kcal h?1 of thermal energy during over 87% syngas generation with the generation of 100 kW electric powers.

Analysis of lead content in automotive shredder residue (ASR)  

Science Journals Connector (OSTI)

Automotive shredder residue (ASR) is a very heterogeneous waste, which could have a very high metal content on finest fractions ?  < 6 mm produced by the shredding of end of live vehicles. The approval of Directive 2000/53/EC and its transposition to the European Union member states requires an analytical technique for in-situ checking of the content of some metals in ASR wastes. The objective of this study is the evaluation of total Pb content in the different fractions using a rapid measurement method to easily accomplish the current legislation. An experimental Energy Dispersive X-ray Fluorescence (EDXRF) spectrometer with tri-axial geometry was used to analyse the ASR in order to test the feasibility of this analytical technique. Likewise, a correction of the intensities by the incoherent scattering (Compton) radiation was made to compensate the matrix effects. The results show that values in the smaller fractions are bigger (11,600 mg kg?1 in the fraction <125 ?m) than in the coarser fractions (4600 mg kg?1 in the fraction between 2 and 6 mm) and that such type of instrumentation enables a fast measurement with a limit of detection of 1.1 mg kg?1 for 1000 s measurement).

Valorization of automotive shredder residue in building materials  

Science Journals Connector (OSTI)

Every year in EU nations, it is estimated that 3 million tonnes of automotive shredder residue (ASR) are generated. Half of the ASR is composed of rubber, textiles and plastics, which can be either transformed into alternative fuel or recycled. The second half, which is landfilled, is incombustible and has not yet been valorized. This waste contains 30% organic matter, as well as inorganic compounds such as quartz, calcite, magnetite, hematite, and anhydrite. It is also very rich in zinc (1–3.5%) and lead (0.7–3.3%). These elements are powerful retarders of ordinary Portland cement. For this reason, two ways of processing of this waste have been investigated: (1) transformation into aggregates after a thermal treatment followed by a chemical treatment or (2) directly into concrete with the use of calcium sulfoaluminate cement. This second way is especially very interesting for engineers and scientists. As established by leaching tests, zinc and lead are integrated and fixed in the structure of ettringite, the main hydration product of calcium sulfoaluminate cement. Therefore, it is possible to produce concrete for some applications including road construction from this currently landfilled “waste” (i.e., the ASR is shown to be useful recyclable material that can be converted into an environmentally friendly “green” concrete).

Automotive shredder residue (ASR) characterization for a valuable management  

Science Journals Connector (OSTI)

Car fluff is the waste produced after end-of-life-vehicles (ELVs) shredding and metal recovery. It is made of plastics, rubber, glass, textiles and residual metals and it accounts for almost one-third of a vehicle mass. Due to the approaching of Directive 2000/53/EC recycling targets, 85% recycling rate and 95% recovery rate in 2015, the implementation of automotive shredder residue (ASR) sorting and recycling technologies appears strategic. The present work deals with the characterization of the shredder residue coming from an industrial plant, representative of the Italian situation, as for annual fluxes and technologies involved. The aim of this study is to characterize ASR in order to study and develop a cost effective and environmentally sustainable recycling system. Results show that almost half of the residue is made of fines and the remaining part is mainly composed of polymers. Fine fraction is the most contaminated by mineral oils and heavy metals. This fraction produces also up to 40% ashes and its LHV is lower than the plastic-rich one. Foam rubber represents around half of the polymers share in car fluff. Moreover, some chemical–physical parameters exceed the limits of some parameters fixed by law to be considered refuse derived fuel (RDF). As a consequence, ASR needs to be pre-treated in order to follow the energy recovery route.

Production of aggregate from non-metallic automotive shredder residues  

Science Journals Connector (OSTI)

In this paper, the results of an experimentation on the production of granules suitable to be used as aggregates in cementitious or asphalt mixes are presented and discussed. The granules were obtained by granulating the non-metallic fraction of automotive shredder residues. In a preliminary separation step the fluff fraction containing mainly inert and non-metallic materials was sieved and analyzed for the metal content. In the following granulation step, the sieved fraction was mixed with binding materials, fly ash and a densifier agent, to produce granules of 5–30 mm of diameter and up to 1400 kg/m3 of specific weight. The granulation was carried out at room temperature in a rotating tank. Concrete samples prepared using as aggregates the produced granules showed a specific weight up to 1800 kg/m3 and a compressive strength up to about 55% of reference samples prepared using a calcareous aggregate, depending on the fluff content of the mixes, and on the nature of the binder and of the other components used.

Fumigation of alcohol in a light duty automotive diesel engine  

SciTech Connect

A light-duty automotive diesel engine was fumigated with methanol and ethanol in amounts up to 35% and 50% of the total fuel energy respectively. The main purpose of this study was to determine the effect of alcohol (methanol and ethanol) fumigation on engine performance at various operating conditions. Engine fuel efficiency, emissions, smoke, and the occurrence of severe knock were the parameters used to evaluate performance. Raw exhaust particulate and its soluble organic extract were screened for biological activity using the Ames Salmonella typhimurium assay. Results are given for a test matrix made up of twelve steady-state operating conditions. For all conditions except the 1/4 rack (light load) condition, modest thermal efficiency gains were noted upon ethanol fumigation. Methanol showed the same increase at 3/4 and full rack (high load) conditions. However, engine roughness or the occurrence of severe knock limited the maximum amount of alcohol that could be fumigated. Brake specific NO/sub x/ concentrations were found to decrease for all ethanol conditions tested. Oxides of nitrogen emissions, on a volume basis, decreased for all alcohol conditions tested. Based on the limited particulate data analyzed, it appears as though ethanol fumigation, like methanol fumigation, while lowering the mass of particulate emitted, does enhance the biological activity of that particulate.

Development of ceramic mixed potential sensors for automotive application  

SciTech Connect

Mixed potential sensors that utilize Gd{sub 0.2}Ce{sub 0.8}O{sub 2} electrolytes and patterned dense 1 {micro}m-thick LaMnO{sub 3} thin films were studied at 600 C and 1%O{sub 2}. The response to C{sub 3}H{sub 6} and CO of two different sensor configurations were studied continuously for 1000 hrs versus an air reference. Although two different current collection schemes and two different metal oxide electrode geometries were employed, the magnitude of the mixed potential generated by both sensors was remarkably similar. From previous work with Au-ceria-Pt mixed potential sensors, this behavior is attributed to precisely controlling the metal oxide electrode/solid electrolyte interface unlike the random interface produced when Au electrodes are used. Although doped ceria is not a suitable electrolyte for automotive exhaust gas applications, this work serves to illustrate design goals for zirconia-based sensors.

User satisfaction modeling framework for automotive audio interfaces  

Science Journals Connector (OSTI)

Abstract Currently the research on product satisfaction is evolving to integrate pleasure and delight alongside other, more traditional needs. Pleasure and delight are emotional and hedonic benefits experienced by the user when interacting with the product. Thus, user satisfaction models have to deal with high complexity of product properties that collectively contribute to satisfaction. The formulation of these models has to include not only a proper taxonomy, but also the organization of such properties in categories and their relation to well defined satisfaction dimensions. Successful models would help to find out the most effective technical and design specifications (engineering parameters) that give shape to specific attributes of design, sometimes called “brand feelings”, defined in accordance with the business strategy. The objective of this paper is to present a user satisfaction modeling framework that deals with the complexity of an in-car user interface, namely the audio one. The proposed framework defines three distinct types of product properties: engineering parameters (P), perceived product attributes (A) and satisfaction dimensions (D) and presents a methodology to link the perceived product attributes (A) to satisfaction dimension (D). Relevance to industry Better understanding of the relationships between perceived and formal properties of automotive audio interfaces in order to contribute to better define their technical and design specifications.

A process for incorporating automotive shredder residue into thermoplastic mouldings  

Science Journals Connector (OSTI)

This paper describes a process for utilising the waste that remains when all of the economically reclaimable materials have been recovered from automobiles that have reached the end of their lives. This waste material, known as automotive shredder residue (ASR), is currently disposed of in landfill sites but forthcoming environmental legislation in the European Union and elsewhere will drastically restrict the amount that can be disposed of in this way. By 2015, 80% of the ASR currently going to landfill must be recycled. The dual injection moulding process is used to mould a skin of virgin polymer over a compound containing the ASR which forms the core of a new component. Polypropylene (PP) was used as the skin material and also as the material to compound with the ASR. A 50%/50% mix by volume of PP and ASR granules was found to produce good results as the core material. Experiments were performed to vary the skin to core ratio in order to establish the effect of varying the proportion of ASR on the mechanical properties of mouldings. It was found that mouldings produced containing 25% by volume of ASR were visually excellent due to the pure PP skin. Inclusion of higher proportions of ASR by decreasing the skin:core thickness ratio was found to produce “breakthrough” of the ASR particles into the skin and test results were highly inconsistent. Using smaller proportions of ASR can be predicted to produce better mechanical properties but would have been contrary to the aim of developing a process capable of disposing of large quantities of ASR. It is concluded that recycling of ASR by using it as a core material in the dual injection moulding process is a feasible option for mouldings requiring good visual appearance but is not suited to components requiring significant strength.

An experiment for urban energy autonomy in Seoul: The One ‘Less’ Nuclear Power Plant policy  

Science Journals Connector (OSTI)

Abstract This study examines an experiment in energy self-sufficiency in Seoul, Republic of Korea, through a particular energy policy called the One Less Nuclear Power Plant (OLNPP) policy. We define an urban energy experiment as a purposive intervention for energy transition from an energy system based on nuclear and fossil fuels to one based on renewable energy and energy demand management. We suggest three findings. First, we find that the themes of our theoretical framework policy backgrounds, governance and policy contents have played important roles for Seoul’s energy experiments aimed at urban energy autonomy. In particular, political leadership based on the mayor’s previous experiences contributed significantly to the formation and implementation of this policy. Second, the OLNPP policy adds a social or moral dimension to urban energy policies. The norm change from an environmental and economic focus to a focus on the combination of social, environmental, and economic considerations is a unique contribution of the OLNPP policy to urban experiments in energy transition. Third, we find that experiments through purposive interventions serve as a means for facilitating urban energy governance where the actors involved can communicate and enhance their new ideas and practices.

Analysis, Simulation and Prediction of Cosmetic Defects on Automotive External Panel  

Science Journals Connector (OSTI)

The first feeling of quality for a vehicle is linked to its perfect appearance. This has a major impact on the reputation of a car manufacturer. Cosmetic defects are thus more and more taken into account in the process design. Qualifying a part as good or bad from the cosmetic point of view is mainly subjective: the part aspect is considered acceptable if no defect is visible on the vehicle by the final customer. Cosmetic defects that appear during sheet metal forming are checked by visual inspection in light inspection rooms stoning or with optical or mechanical sensors or feelers. A lack of cosmetic defect prediction before part production leads to the need for corrective actions production delays and generates additional costs.

Use of Fault Tree Analysis for Automotive Reliability and Safety Analysis  

SciTech Connect

Fault tree analysis (FTA) evolved from the aerospace industry in the 1960's. A fault tree is deductive logic model that is generated with a top undesired event in mind. FTA answers the question, ''how can something occur?'' as opposed to failure modes and effects analysis (FMEA) that is inductive and answers the question, ''what if?'' FTA is used in risk, reliability and safety assessments. FTA is currently being used by several industries such as nuclear power and chemical processing. Typically the automotive industries uses failure modes and effects analysis (FMEA) such as design FMEAs and process FMEAs. The use of FTA has spread to the automotive industry. This paper discusses the use of FTA for automotive applications. With the addition automotive electronics for various applications in systems such as engine/power control, cruise control and braking/traction, FTA is well suited to address failure modes within these systems. FTA can determine the importance of these failure modes from various perspectives such as cost, reliability and safety. A fault tree analysis of a car starting system is presented as an example.

Durability of polymer matrix composites for automotive structural applications: A state-of-the-art review  

SciTech Connect

A key unanswered question that must be addressed before polymeric composites will be widely used in automotive structural components is their known durability. Major durability issues are the effects that cyclic loadings, creep, automotive fluid environments, and low-energy impacts have on dimensional stability, strength, and stiffness throughout the required life of a composite component. This report reviews the current state of understanding in each of these areas. It also discusses the limited information that exists on one of the prime candidate materials for automotive structural applications--an isocyanurate reinforced with a continuous strand, swirl mat. Because of the key role that nondestructive evaluations must play in understanding damage development and progression, a chapter is included on ultrasonic techniques. A final chapter then gives conclusions and recommendations for research needed to resolve the various durability issues. These recommendations will help provide a sound basis for program planning for the Durability of Lightweight Composite Structures Project sponsored by the US Department of Energy in cooperation with the Automotive Composites Consortium of Chrysler, Ford, and General Motors.

Beginning the fall semester of 1999, The University of Maryland, Departments of Mechanical and Electrical Engineering and the Institute for Systems Research served as a U.S. Department of Energy (USDOE) Graduate Automotive Technology Education (GATE) Center for Hybrid Electric Drivetrains and Control Strategies. A key goal was to produce a graduate level education program that educated and prepared students to address the technical challenges of designing and developing hybrid electric vehicles, as they progressed into the workforce. A second goal was to produce research that fostered the advancement of hybrid electric vehicles, their controls, and other related automotive technologies. Participation ended at the University of Maryland after the 2004 fall semester. Four graduate courses were developed and taught during the course of this time, two of which evolved into annually-taught undergraduate courses, namely Vehicle Dynamics and Control Systems Laboratory. Five faculty members from Mechanical Engineering, Electrical Engineering, and the Institute for Systems Research participated. Four Ph.D. degrees (two directly supported and two indirectly supported) and seven Master's degrees in Mechanical Engineering resulted from the research conducted. Research topics included thermoelectric waste heat recovery, fuel cell modeling, pre- and post-transmission hybrid powertrain control and integration, hybrid transmission design, H{sub 2}-doped combustion, and vehicle dynamics. Many of the participating students accepted positions in the automotive industry or government laboratories involved in automotive technology work after graduation. This report discusses the participating faculty, the courses developed and taught, research conducted, the students directly and indirectly supported, and the publication list. Based on this collection of information, the University of Maryland firmly believes that the key goal of the program was met and that the majority of the participating students are now contributing to the advancement of automotive technology in this country.

Influence of speed and frequency towards the automotive turbocharger turbine performance under pulsating flow conditions  

Science Journals Connector (OSTI)

Abstract The ever-increasing demand for low carbon applications in automotive industry has intensified the development of highly efficient engines and energy recovery devices. Even though there are significant developments in the alternative powertrains such as full electric, their full deployment is hindered by high costing and unattractive life-cycle energy and emission balance. Thus powertrain based on highly efficient internal combustion engines are still considered to be the mainstream for years to come. Traditionally, turbocharger has been an essential tool to boost the engine power, however in recent years it is seen as an enabling technology for engine downsizing. It is a well-known fact that a turbocharger turbine in an internal combustion engine operates in a highly pulsating exhaust flow. There are numerous studies looking into the complex interaction of the pulsating exhaust gas within the turbocharger turbine, however the phenomena is still not fully integrated into the design stage. Industry practice is still to design and match the turbine to an engine based on steady performance maps. The current work is undertaken with the mind to move one step closer towards fully integrating the pulsating flow performance into the turbocharger turbine design. This paper presents the development efforts and results from a full 3-D CFD model of a turbocharger turbine stage. The simulations were conducted at 30,000 rpm and 48,000 rpm (50% and 80% design speed respectively) for both 20 Hz and 80 Hz pulsating flow inlet conditions. Complete validation procedure using cold-flow experimental data is also described. The temporal and spatial resolutions of the incidence angle at the rotor leading edge suggest that the circumference variation is little (7%) as compared to its variation in time as the pulse progresses. The primary aim of this paper is to investigate the relationship of the turbine speed, as well as the pulsating flow frequency to its performance. It was found that there are no direct instantaneous relationship between the pulsating pressure at the turbine inlet and the turbine efficiency, except when one considers an additional parameter, namely the incidence angle. This paper also intends to investigate the potential loss of information if the performance parameters are simply averaged without considering the instantaneous effects.

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

Real-time Predictive Control: From Automotive Systems to Real-time Predictive Control: From Automotive Systems to Energy Efficient Buildings Speaker(s): Francesco Borrelli Date: February 10, 2010 - 12:00pm Location: 90-3122 Hybrid systems are heterogeneous systems that exhibit both continuous and discrete dynamics. Over the last eight years we have focused on the development of systematic, real-time, predictive controller synthesis techniques for hybrid systems with constraints. In this talk I will first summarize our theoretical efforts starting from constrained optimal control design for hybrid systems with constraints. Then, I will show how these results can be used in order to develop a theory for distributed predictive control for large-scale systems. The second part of the talk presents a range of applications where the proposed techniques were used with great

Automotive Underhood Thermal Management Analysis Using 3-D Coupled Thermal-Hydrodynamic Computer Models: Thermal Radiation Modeling  

SciTech Connect

The goal of the radiation modeling effort was to develop and implement a radiation algorithm that is fast and accurate for the underhood environment. As part of this CRADA, a net-radiation model was chosen to simulate radiative heat transfer in an underhood of a car. The assumptions (diffuse-gray and uniform radiative properties in each element) reduce the problem tremendously and all the view factors for radiation thermal calculations can be calculated once and for all at the beginning of the simulation. The cost for online integration of heat exchanges due to radiation is found to be less than 15% of the baseline CHAD code and thus very manageable. The off-line view factor calculation is constructed to be very modular and has been completely integrated to read CHAD grid files and the output from this code can be read into the latest version of CHAD. Further integration has to be performed to accomplish the same with STAR-CD. The main outcome of this effort is to obtain a highly scalable and portable simulation capability to model view factors for underhood environment (for e.g. a view factor calculation which took 14 hours on a single processor only took 14 minutes on 64 processors). The code has also been validated using a simple test case where analytical solutions are available. This simulation capability gives underhood designers in the automotive companies the ability to account for thermal radiation - which usually is critical in the underhood environment and also turns out to be one of the most computationally expensive components of underhood simulations. This report starts off with the original work plan as elucidated in the proposal in section B. This is followed by Technical work plan to accomplish the goals of the project in section C. In section D, background to the current work is provided with references to the previous efforts this project leverages on. The results are discussed in section 1E. This report ends with conclusions and future scope of work in section F.

Advanced high temperature materials for the energy efficient automotive Stirling engine  

SciTech Connect

The Stirling engine is under investigation jointly by the Department of Energy and NASA Lewis as an alternative to the internal combustion engine for automotive applications. The Stirling engine is an external combustion engine that offers the advantage of high fuel economy, low emissions, low noise, and low vibrations compared to current internal combustion automotive engines. The most critical component from a materials viewpoint is the heater head consisting of the cylinders, heating tubes, and regenerator housing. Materials requirements for the heater head include compatibility with hydrogen, resistance to hydrogen permeation, high temperature oxidation/corrosion resistance and high temperature creep-rupture and fatigue properties. A continuing supporting materials research and technology program has identified the wrought alloys CG-27 and 12RN72 and the cast alloys XF-818 and NASAUT 4G-A1 as candidate replacements for the cobalt containing alloys used in current prototype engines. Based on the materials research program in support of the automotive Stirling engine it is concluded that manufacture of the engine is feasible from low cost iron-base alloys rather than the cobalt alloys used in prototype engines. This paper will present results of research that led to this conclusion.

Atmospheric chemistry of automotive fuel additives: Diisopropyl ether  

SciTech Connect

To quantify the atmospheric reactivity of diisopropyl ether (DIPE), we have conducted a study of the kinetics and mechanism of reaction 1: OH + DIPE {r_arrow} products. Kinetic measurements of reaction 1 were made using both relative (at 295 K) and absolute techniques (over the temperature range 240-440 K). Rate data from both techniques can be represented by the following: k{sub 1} = (2.2{sub -0.8}{sup +14}) x 10{sup -12} exp[(445 {plus_minus} 145)/T] cm{sup 3} molecule{sup -1}s{sup -1}. At 298 K, k{sub 1} = 9.8 x 10{sup -12} cm{sup 3} molecule{sup -1}s{sup -1}. The products of the simulated atmospheric oxidation of DIPE were identified using FT-IR spectroscopy; isopropyl acetate and HCHO were the main products. The atmospheric oxidation of DIPE can be represented by i-C{sub 3}H{sub 7}O-i-C{sub 3}H{sub 7} + OH + 2NO {r_arrow} HCHO + i-C{sub 3}H{sub 7}OC(O)CH{sub 3} + HO{sub 2} + 2NO{sub 2}. Our kinetic and mechanistic data were incorporated into a 1-day simulation of atmospheric chemistry to quantify the relative incremental reactivity of DIPE. Results are compared with other oxygenated fuel additives. 30 refs., 9 figs.

Investigation and demonstration of the durability of air plasma pre-treatment on polypropylene automotive bumpers  

Science Journals Connector (OSTI)

Higher utilisation of low-density materials such as polymers and polymer composites is a pre-requisite for the lightweight vehicle of the future. Of the commodity polymers polypropylene (PP) is by far the most attractive for the automotive industry. Additionally, PP can be utilised as a glass or mineral filled composite which may be used for semi-structural applications. A major problem is that PP (along with other polyolefins) has a non-polar surface chemistry which means the wetting characteristics of components made from this material are poor. Ultimately, this will result in poor adhesion of paints, coatings or adhesive bonding products. This problem has been overcome in the majority of instances by treating the surface of the substrate in order to alter the surface chemistry. PP has found extensive use as films and flat sheets and hence certain techniques such as flame and corona have been favoured despite both having problems of heterogeneous or patchy treatment across a surface. However, for complex 3-D automotive shapes, such as bumpers, these methods are less useful. While flame treatment for example is widely used it has several disadvantages in a commercial volume production environment which all centre around the potential for the part to undergo overtreatment, incipient melting or melting during machine stops etc., as well as the hazards associated with combustible gas. An alternative method is atmospheric plasma pre-treatment. This work has investigated the effect of a forced air plasma pre-treatment on surface chemistry and bond strength of a commercial grade polypropylene material. The plasma head was attached to a robot arm which makes it highly suited to continuous production environments and can treat complex surfaces. A range of translation speeds were investigated and the surface chemistry and topography of the treated surfaces were examined using atomic force microscopy and X-ray photoelectron spectroscopy. The processing was further optimised by single lap-shear testing. An optimised set of parameters was used to pre-treat and bond a full size automotive bumper assembly with a polyurethane (PU) adhesive. Bumpers were then subjected to a standard automotive range of climate conditioning as well as soaking at ?20°C and 70°C before front centre impact testing. Parts pre-treated and bonded using this pre-treatment and adhesive system, successfully passed all the required standard automotive impact tests. For added benefit, it was also found that the open time of the pre-treatment was 1 week depending on storage conditions.

Risk Profiles for the Pre-series Logistics in Automotive Ramp-up Processes  

Science Journals Connector (OSTI)

Abstract The increasing complexity and shortening process duration of ramp-up projects in the automotive industry causes research and industry since years to optimise the ramp-up phase and develop supporting methodologies. Risk management seems to be a promising approach to identify and analyse critical processes. This paper presents a risk survey approach, based on the knowledge of existing methodologies for the ramp-up management. The applicability of these methods and tools depends on the project-specific risks within the sub-processes of the ramp-up phase. Hence, suitable indicators are necessary to monitor the risk drivers and sources and thus to identify the risks. Nevertheless, the adoption of suitable indicators from these sets for an individual pre-series project requires the derivation of a specific risk profile. Based on a framework of pre-series logistics sub-processes a survey approach will be presented, allowing to deduce risk profiles for ramp-up projects. Following, the results of an exemplary survey, which has been conducted at a German premium automotive manufacturer and the resulting logistical risk profile are presented. The paper concludes with a summary and an outlook on further research.

Development of flame retarded self-reinforced composites from automotive shredder plastic waste  

Science Journals Connector (OSTI)

Multilayered self-reinforced composites were developed from a density-separated light fraction of automotive shredder waste of high polyolefin content, which can fulfil the current technical, safety and environmental requirements of structural materials. The significantly enhanced mechanical properties of the recycled composites were ensured by polypropylene fabric reinforcement; meanwhile, reduced flammability was obtained by modifying the matrix layers, made of secondary raw materials, with phosphorous-containing flame retardant additive. The results of the new flame retarded composite systems allowed the discussion of a novel mechanistic observation. The mechanical and flammability properties of the prepared self-reinforced composites are compared to conventional glass fabric reinforced composites and to compounds without reinforcement.

High-tech marketing communication in the automotive industry: a content analysis of print advertisements  

Science Journals Connector (OSTI)

Appropriate marketing communication is critical for the success of a product. Especially in high-tech markets, the adoption of new products is challenging, as customers' willingness to buy a product can be hindered by a lack of knowledge and experience. The choice of information content given in advertisements is, therefore, crucial. Despite its importance, research on advertising in high-tech markets is still underrepresented. The aim of this study is, hence, to examine advertising activities of high-tech products. As research object, print advertisements of OEMs from the automotive industry have been chosen, as cars are technologically advanced products, which incorporate a wide range of technologies. Based on an explorative content analysis, 708 car print advertisements, published between 2005 and 2012, are examined. The findings show, e.g., that value and user experience is the most frequently found information cue, whereas price and safety aspects are only communicated in the minority of the analysed advertisements.

Overview of DOE'S programs on aluminum and magnesium for automotive application  

SciTech Connect

The U.S. Department of Energy will present an update and review of its programs in aluminum and magnesium for automotive and heavy-duty vehicle applications. While the main programs focused on vehicle materials are in the Office of Transportation Technologies, contributing efforts will be described in the DOE Office of Industrial Technologies and the DOE Office of Energy Research. The presentation will discuss materials for body/chassis and power train, and will highlight the considerable synergy among the efforts. The bulk of the effort is on castings, sheet, and alloys with a smaller focus on metal matrix composites. Cost reduction and energy savings are the overriding themes of the programs.

Evaluation of asthmatic volunteers' pulmonary responses to effluents from automotive airbags  

Science Journals Connector (OSTI)

Deploying automotive airbags release potential respiratory irritants at high concentrations. We evaluated the respiratory irritancy of six contemporary prototype driver/passenger airbag systems, using a previously established USA auto industry protocol for human testing. For each system, ten volunteers with asthma were exposed individually inside an automobile passenger compartment, during deployment and for 20 minutes afterwards. Symptoms and lung function were monitored for two hours after exposure. All airbag systems fulfilled the established standard of no more than three in ten subjects with positive response (defined as clinically meaningful lung function disturbance plus increased asthma symptoms). Three systems evoked no positive responses. Statistically significant (P<0.005) differences in lung function and symptom responses between systems were not accurately predictable from measured pollutant concentrations. Conclusions: contemporary airbag designs vary appreciably in their potential to provoke asthma. Airbag testing with potentially susceptible human subjects can be useful in pre-market evaluation.

Engine coolant compatibility with the nonmetals found in automotive cooling systems  

SciTech Connect

High temperature, short term immersion testing was used to determine the impact of propylene and ethylene glycol base coolants on the physical properties of a variety of elastomeric and thermoplastic materials found in automotive cooling systems. The materials tested are typically used in cooling system hoses, radiator end tanks, and water pump seals. Traditional phosphate or borate-buffered silicated coolants as well as extended-life organic acid formulations were included. A modified ASTM protocol was used to carry out the testing both in the laboratory and at an independent testing facility. Post-test fluid chemistry including an analysis of any solids which may have formed is also reported. Coolant impact on elastomer integrity as well as elastomer-induced changes in fluid chemistry were found to be independent of the coolant`s glycol base.

Science Journals Connector (OSTI)

Abstract This paper proposes an approach to the design and operation of assembly systems that include mobile robots. It is based on a semantic model representing the robot/resource skills along with the operations that a resource has to execute. The method is implemented in a system capable of generating the assignment of operations to the proper robotic resources. Collision free paths can be generated for the assembly system robots with the help of simulation. The method is presented in a case study from the automotive industry.

Sustainability assessment of industrial waste treatment processes: The case of automotive shredder residue  

Science Journals Connector (OSTI)

To date numerous environmental, economic and societal indicators have been applied to evaluate and compare the sustainability of products and processes. This study presents a set of ad hoc sustainability indicators suitable for assessing and comparing processes for the treatment of industrial waste streams and for allowing to address efficiently all aspects of sustainability. This set consists of the following indicators: energy intensity, material intensity, water consumption, land use, global warming, human toxicity and treatment cost. The application of these indicators to industrial waste treatment processes is discussed in depth. A distinction is made between direct contributions to sustainability, occurring at the process level itself, and indirect contributions related to the production of auxiliaries and the recovery of end products. The proposed sustainability assessment method is applied to treatment processes for automotive shredder residue (ASR), a complex and heterogeneous waste stream with hazardous characteristics. Although different strategies for recycling and valorization of ASR were developed, with some of them already commercialized, large quantities of ASR are still commonly landfilled. This study concludes that for ASR the most sustainable alternative to the present landfill practice, both in short and long term perspective, consists of recycling combined with energetic valorization of the residual fraction.

Review of Italian experience on automotive shredder residue characterization and management  

Science Journals Connector (OSTI)

Abstract Automotive Shredder Residue (ASR) is a special waste that can be classified as either hazardous or non hazardous depending on the amount of hazardous substances and on the features of leachate gathered from EN12457/2 test. However both the strict regulation concerning landfills and the EU targets related to End-of-Life Vehicles (ELVs) recovery and recycling rate to achieve by 2015 (Directive 2000/53/EC), will limit current landfilling practice and will impose an increased efficiency of \\{ELVs\\} valorization. The present paper considers \\{ELVs\\} context in Italy, taking into account \\{ASRs\\} physical–chemical features and current processing practice, focusing on the enhancement of secondary materials recovery. The application in waste-to-energy plants, cement kilns or metallurgical processes is also analyzed, with a particular attention to the possible connected environmental impacts. Pyrolysis and gasification are considered as emerging technologies although the only use of ASR is debatable; its mixing with other waste streams is gradually being applied in commercial processes. The environmental impacts of the processes are acceptable, but more supporting data are needed and the advantage over (co-)incineration remains to be proven.

Comparative thermodynamic and experimental study of some heavy metal behaviours during automotive shredder residues incineration  

Science Journals Connector (OSTI)

Experimental and theoretical studies of the behaviour of some heavy metals were undertaken during Automotive Shredder Residues (ASR) incineration. A thermodynamic study at equilibrium was performed using a software minimizing the free Gibbs energy. The metals studied were barium, copper, lead and zinc. The studies were performed mostly at two temperatures: 1123 and 1373 K. The thermodynamic study showed that the chlorine content is the most important parameter influencing the volatility of the studied metals. It also showed that in default of chlorine in a system containing several metals, barium chloride in its condensed form is the most easily formed. Other metals remained in their metallic form or in the form of oxides. The presence of hydrogen in the system has a general limiting influence on the metal volatility because, especially at high temperatures, hydrogen chloride is more likely to be formed. In the experimental field, the behaviours of metals were studied using commercial polymers as waste models: a PVC mastic, a polyurethane mastic and a rubber powder. Copper and barium presented a non volatile behaviour during the incineration of waste matrixes as ASR, being present also in residual ash. On the other hand, lead was completely formed in the gas phase and zinc showed an equal partitioning between the two principal phases of the treatment. ©

Control of Two Permanent Magnet Machines Using a Five-Leg Inverter for Automotive Applications  

SciTech Connect

This paper presents digital control schemes for control of two permanent magnet (PM) machines in an integrated traction and air-conditioning compressor drive system for automotive applications. The integrated drive system employs a five-leg inverter to power a three-phase traction PM motor and a two-phase compressor PM motor by tying the common terminal of the two-phase motor to the neutral point of the three-phase motor. Compared to a three-phase or a standalone two-phase inverter, it eliminates one phase leg and shares the control electronics between the two drives, thus significantly reducing the component count of the compressor drive. To demonstrate that the speed and torque of the two PM motors can be controlled independently, a control strategy was implemented in a digital signal processor, which includes a rotor flux field orientation based control (RFOC) for the three-phase motor, a similar RFOC and a position sensorless control in the brushless dc (BLDC) mode for the two-phase motor. Control implementation issues unique to a two-phase PM motor are also discussed. Test results with the three-phase motor running in the ac synchronous (ACS) mode while the two-phase motor either in the ACS or the BLDC mode are included to verify the independent speed and torque control capability of the integrated drive.

Technical assessment of compressed hydrogen storage tank systems for automotive applications.  

SciTech Connect

The performance and cost of compressed hydrogen storage tank systems has been assessed and compared to the U.S. Department of Energy (DOE) 2010, 2015, and ultimate targets for automotive applications. The on-board performance and high-volume manufacturing cost were determined for compressed hydrogen tanks with design pressures of 350 bar ({approx}5000 psi) and 700 bar ({approx}10,000 psi) capable of storing 5.6 kg of usable hydrogen. The off-board performance and cost of delivering compressed hydrogen was determined for hydrogen produced by central steam methane reforming (SMR). The main conclusions of the assessment are that the 350-bar compressed storage system has the potential to meet the 2010 and 2015 targets for system gravimetric capacity but will not likely meet any of the system targets for volumetric capacity or cost, given our base case assumptions. The 700-bar compressed storage system has the potential to meet only the 2010 target for system gravimetric capacity and is not likely to meet any of the system targets for volumetric capacity or cost, despite the fact that its volumetric capacity is much higher than that of the 350-bar system. Both the 350-bar and 700-bar systems come close to meeting the Well-to-Tank (WTT) efficiency target, but fall short by about 5%. These results are summarized.

Exergetic analysis of a thermo-generator for automotive application: A dynamic numerical approach  

Science Journals Connector (OSTI)

It is well known that when using a passenger car with an ICE (Internal Combustion Engine) only a fraction of the burnt fuel energy actually contributes to drive the vehicle. Typical passenger vehicle engines run about 25% efficiency while a great part of the remaining energy (about 40%) is lost through the exhaust gases. This latter has a significant energy conversion potential since the temperature (more than 300°C) and the mass flow rate are high enough. Thus direct conversion of heat into electricity is a credible option if the overall system is optimized. This point is crucial since the heat conversion into work process is very sensible to any mismatching of the different parts of the system and very sensible significant to the possible varying working conditions. All these effects constitute irreversibility sources that degrade the overall efficiency. The exergetic analysis is known to be an efficient tool for finding the root causes of theses irreversible processes. In order to investigate the performance of our automotive thermo-generator we propose an analysis of the exergy flow through the system under dynamic conditions. Taking into account the different irreversible sources such as thermal conduction and Joule effect we are able to localize and quantify the exergy losses. Then in order to optimize the thermoelectric converter for a given vehicle correct actions in term of design and working conditions can be proposed.

Fleet test evaluations of an automotive and medium-duty truck coolant filter conditioner  

SciTech Connect

The use of coolant filtration and supplemental coolant additives (SCA) to replenish depleted protective chemistry has been applied in the heavy duty diesel arena for many years. Some filtration of coolant and SCA usage in light gasoline engine and automotive diesel engine vehicles has taken place using off-board equipment to filter and recondition coolant. As concerns about the environment have increased, disposal of spent coolant that is replaced on a scheduled basis is a burden on fleets as well as individuals. In addition, as the efforts by vehicle manufacturers to extend or eliminate routine service intervals of vehicle systems increase, the use of an on-board system has become more attractive. A number of filtration/conditioning designs have been developed for light and medium duty use and have been on field tests for over a year. These field tests are described and reported, along with background on the filter design and chemistry package used. Field testing included: low and high mileage vehicles; newer and older vehicles; well and poorly maintained vehicles; and an assessment of the possibility of overcharging of the coolant chemistry.

The California greenhouse gas initiative and its implications to the automotive industry  

SciTech Connect

CAR undertook this investigation to better understand the costs and challenges of a local (state) regulation necessitating the implementation of alternative or advanced powertrain technology. CAR will attempt to add insight into the challenges that local regulations present to the automotive industry, and to contribute further to the discussion of how advanced powertrain technology may be used to meet such regulation. Any local law that (directly or indirectly) affects light duty motor vehicle fuel economy creates what in effect is a specialty market for powertrain technology. As such these small markets present significant challenges for automotive manufacturers. First, a small market with unique standards presents significant challenges to an industry that has sustained growth by relying on large volumes to achieve scale economies and deliver products at a cost acceptable to the consumer. Further, the challenges of the additional technology make it likely that any powertrain capable of meeting the stringent emissions standards will include costly additional components, and thus will be more costly to manufacture. It is likely that manufacturers would consider the following actions as steps to deliver products to meet the pending California regulatory requirements anticipated as a result of prior California legislation: (1) Substituting more fuel efficient vehicles: Bring in more efficient vehicles from global operations, while likely dropping existing domestic products. (2) Substituting powertrains: Add existing downsized engines (i.e. turbocharged versions, etc.) into California market-bound vehicles. (3) Powertrain enhancements: Add technology to current engine and transmission offerings to improve efficiency and reduce emissions. (4) Incorporating alternative powertrains into existing vehicle platforms: Develop a hybrid or other type of powertrain for an existing vehicle. (5) New powertrains and new platforms: Develop vehicles specifically intended to incorporate new powertrain technologies, materials and/or design (e.g. the General Motors EV1 or the Toyota Prius). These five actions represent the gamut from the least complicated solution to the most complex. They also generally represent the least expensive response to the most expensive. It is possible that the least expensive responses may be least likely to meet market demands while achieving required GHG emission limits. At the same time, the most expensive option may produce a vehicle that satisfies the GHG reduction requirements and meets some consumer requirements, but is far too costly to manufacture and sell profitably. The response of a manufacturer would certainly have to take market size, consumer acceptance, technology implication and cost, as well as internal capacities and constraints, into consideration. It is important to understand that individual companies may respond differently in the short term. However, it is probable that there would be a more consistent industry-wide response in the longer term. Options 1 and 2 present the simplest responses. A company may reach into its global portfolio to deliver vehicles that are more fuel-efficient. These vehicles are usually much smaller and significantly less powerful than current U.S. offerings. Industry respondents indicated that such a strategy may be possible but would likely be met with less than positive reaction from the buying public. A general estimate for the cost to homologize a vehicle--that is, to prepare an existing vehicle for entry into the United States provided all business conditions were met (reasonable product, capacity availability, etc.), would be approximately $50 million. Assuming an estimated cost for homologation to meet U.S. standards of $50 million and a 20,000 vehicle per year sales volume in California, the company would then incur a $2,500 per-vehicle cost to bring them into the market. A manufacturer may also choose to incorporate a more efficient powertrain into a vehicle already sold in the market. The costs associated with such a strategy would include reengineering

A critical review of developments in the pyrolysis of automotive shredder residue  

Science Journals Connector (OSTI)

Worldwide, automotive shredder residue (ASR) is considered an increasingly problematic mixture of materials that needs the development of a processing solution. Pyrolysis is a process that has many advantages to offer, but despite many studies and developments in recent years at various levels of commercialisation, it is still generally considered unproven for this purpose. This paper critically considers developmental work published in the field, presents new results, and suggests that a major reason for the lack of development is the complexity of the landscape created by strong, competing, economic, legislative, environmental and commercial drivers, which in turn make it unclear which products and processes are optimal. This is made doubly complex by the natural variation in the material composition of ASR, with contaminants that can critically affect its potential fate to anywhere in the range from hazardous waste, to energy source, to useful raw material for major cement or steel industries. New data on critical factors such as levels of chlorine and metals in raw and pyrolysed ASR are presented, alongside a much-needed summary of previously published values from references that are often difficult to source. The summaries emphasise the variation in the material, but also indicate rough boundaries for values, which are needed for the design of any potentially successful process. It is suggested that the heterogeneity seen across ASR types implies that specialised processing of SR on its own is unlikely. It is pointed out that small-scale processes that could be suitable for local requirements should be considered for development as they could be able to optimise a process sufficiently to make it viable, e.g. specialised local waste streams of paper pulp and a particular fraction of SR.

Performance and cost of automotive fuel cell systems with ultra-low platinum loadings.  

SciTech Connect

An automotive polymer-electrolyte fuel cell (PEFC) system with ultra-low platinum loading (0.15 mg-Pt cm{sup -2}) has been analyzed to determine the relationship between its design-point efficiency and the system efficiency at part loads, efficiency over drive cycles, stack and system costs, and heat rejection. The membrane electrode assemblies in the reference PEFC stack use nanostructured, thin-film ternary catalysts supported on organic whiskers and a modified perfluorosulfonic acid membrane. The analyses show that the stack Pt content can be reduced by 50% and the projected high-volume manufacturing cost by >45% for the stack and by 25% for the system, if the design-point system efficiency is lowered from 50% to 40%. The resulting penalties in performance are a <1% reduction in the system peak efficiency; a 2-4% decrease in the system efficiency on the urban, highway, and LA92 drive cycles; and a 6.3% decrease in the fuel economy of the modeled hybrid fuel-cell vehicle on the combined cycle used by EPA for emission and fuel economy certification. The stack heat load, however, increases by 50% at full power (80 kW{sub e}) but by only 23% at the continuous power (61.5 kW{sub e}) needed to propel the vehicle on a 6.5% grade at 55 mph. The reduced platinum and system cost advantages of further lowering the design-point efficiency from 40% to 35% are marginal. The analyses indicate that thermal management in the lower efficiency systems is very challenging and that the radiator becomes bulky if the stack temperature cannot be allowed to increase to 90-95 C under driving conditions where heat rejection is difficult.

Technical assessment of cryo-compressed hydrogen storage tank systems for automotive applications.  

SciTech Connect

On-board and off-board performance and cost of cryo-compressed hydrogen storage has been assessed and compared to the DOE 2010, 2015 and ultimate targets for automotive applications. The Gen-3 prototype system of Lawrence Livermore National Laboratory was modeled to project the performance of a scaled-down 5.6-kg usable hydrogen storage system. The on-board performance of the system and high-volume manufacturing cost were determined for liquid hydrogen refueling with a single-flow nozzle and a pump that delivers 1.5 kg/min of liquid H{sub 2} to the insulated cryogenic tank capable of being pressurized to 272 atm (4000 psi). The off-board performance and cost of delivering liquid hydrogen were determined for two scenarios in which hydrogen is produced by central steam methane reforming (SMR) and by central electrolysis using electricity from renewable sources. The main conclusions from the assessment are that the cryo-compressed storage system has the potential of meeting the ultimate target for system gravimetric capacity and the 2015 target for system volumetric capacity (see Table I). The system compares favorably with targets for durability and operability although additional work is needed to understand failure modes for combined pressure and temperature cycling. The system may meet the targets for hydrogen loss during dormancy under certain conditions of minimum daily driving. The high-volume manufacturing cost is projected to be 2-4 times the current 2010 target of $4/kWh. For the reference conditions considered most applicable, the fuel cost for the SMR hydrogen production and liquid H{sub 2} delivery scenario is 60%-140% higher than the current target of $2-$3/gge while the well-to-tank efficiency is well short of the 60% target specified for off-board regenerable materials.

Investigation on combustion characteristics of crude rice bran oil methyl ester blend as a heavy duty automotive engine fuel  

Science Journals Connector (OSTI)

In the present work, an attempt was made to test the suitability of crude rice bran oil methyl ester (CRBME) blend as a heavy duty automotive engine fuel. A four stroke, six cylinder direct injection 117.6 kW turbo-charged compression ignition (CI) engine was used for the work. The operation of the engine with CRBME blend showed that the peak pressure increased with lower maximum rate of pressure rise and maximum heat release rate with shorter delay period. Burning rate of the CRBME blend was slower and required a higher crank angle to complete the combustion cycle when compared to diesel. The brake thermal efficiency of the CRBME blend was lower than that of diesel at all speeds except at 2300rpm. As the measured combustion and performance parameters for CRBME blend differs only by a smaller magnitude when compared with diesel, this investigation ensures the suitability of the CRBME blend as fuel for heavy duty automotive engine without any design modifications [Received: August 12, 2010; Accepted: August 29, 2010

Leachability of automotive shredder residues burned in a fluidized bed system  

Science Journals Connector (OSTI)

This paper presents the results of the study of a combustible fraction of automotive shredder residues (CASRs) and the corresponding ashes generated by combustion on a fluidized bed pilot with the aim to understand the influence of thermal treatment regarding properties for final disposal, such as landfilling. The chemical composition was evaluated and the leachability behaviour of ashes and CASR was investigated using the three more commonly used tests: the European Standard EN 12457, the US TCLP-EPA 1311 and the Dutch availability test EA NEN 7371. Different results were obtained depending on the specific conditions of the methods employed. It was found that both the CASR and the ashes contained large amounts of toxic metals and other undesirable elements, such as Cl and S. For the CASR, in addition to the leachability of organic matter above the limit set for hazardous materials, the release of heavy metals, either under alkaline and acidic conditions was significant, revealing the serious risks associated to the landfilling practices still being undertaken worldwide. Release of organic matter from ashes was insignificant, but solubility of sulphates increased and chlorides exceed the hazardous limits in the case of fly ashes. Toxic metals were found to leach from the ashes only under acidic conditions, except Pb and Cu which also leached from finer ashes at alkaline pH. Cr also leached from ashes at alkaline pH values. Both the Dutch availability and TCLP revealed much higher leaching intensities than the European Standard due to the acidity of leachants. However, it was found that ashes may be more resistant to acidification because they exhibit much higher acid neutralization capacity (ANC) than the untreated CASR. The study undertaken shows that thermal valorisation of the combustible fraction of ASR may avoid the risks associated with their landfilling; however, care has to be taken with the ashes because they also behave as hazardous residues. Although, the mass reduction provided by thermal treatment may make landfilling less expensive, a more profitable reutilization of the ashes should be developed.

Quantum Simulation  

E-Print Network (OSTI)

Simulating quantum mechanics is known to be a difficult computational problem, especially when dealing with large systems. However, this difficulty may be overcome by using some controllable quantum system to study another less controllable or accessible quantum system, i.e., quantum simulation. Quantum simulation promises to have applications in the study of many problems in, e.g., condensed-matter physics, high-energy physics, atomic physics, quantum chemistry and cosmology. Quantum simulation could be implemented using quantum computers, but also with simpler, analog devices that would require less control, and therefore, would be easier to construct. A number of quantum systems such as neutral atoms, ions, polar molecules, electrons in semiconductors, superconducting circuits, nuclear spins and photons have been proposed as quantum simulators. This review outlines the main theoretical and experimental aspects of quantum simulation and emphasizes some of the challenges and promises of this fast-growing field.

Program Final Report - Develop Thermoelectric Technology for Automotive Waste Heat Recovery  

SciTech Connect

We conducted a vehicle analysis to assess the feasibility of thermoelectric technology for waste heat recovery and conversion to useful electrical power and found that eliminating the 500 W of electrical power generated by the alternator corresponded to about a 7% increase in fuel economy (FE) for a small car and about 6% for a full size truck. Electric power targets of 300 W were established for city and highway driving cycles for this project. We obtained critical vehicle level information for these driving cycles that enabled a high-level design and performance analysis of radiator and exhaust gas thermoelectric subsystems for several potential vehicle platforms, and we identified the location and geometric envelopes of the radiator and exhaust gas thermoelectric subsystems. Based on this analysis, we selected the Chevrolet Suburban as the most suitable demonstration vehicle for this project. Our modeling and thermal analysis assessment of a radiator-based thermoelectric generator (TEG), however, revealed severe practical limitations. Specifically the small temperature difference of 100°C or less between the engine coolant and ambient air results in a low Carnot conversion efficiency, and thermal resistance associated with air convection would reduce this conversion efficiency even further. We therefore decided not to pursue a radiator-based waste heat recovery system and focused only on the exhaust gas. Our overall approach was to combine science and engineering: (1) existing and newly developed TE materials were carefully selected and characterized by the material researcher members of our team, and most of the material property results were validated by our research partners, and (2) system engineers worked closely with vehicle engineers to ensure that accurate vehicle-level information was used for developing subsystem models and designs, and the subsystem output was analyzed for potential fuel economy gains. We incorporated material, module, subsystem, and integration costs into the material selection criteria in order to balance various materials, module and subsystem design, and vehicle integration options. Our work on advanced TE materials development and on TEG system design, assembly, vehicle integration, and testing proceeded in parallel efforts. Results from our two preliminary prototype TEGs using only Bi-Te TE modules allowed us to solve various mechanical challenges and to finalize and fine tune aspects of the design and implementation. Our materials research effort led us to quickly abandon work on PbTe and focus on the skutterudite materials due to their superior mechanical performance and suitability at automotive exhaust gas operating temperatures. We synthesized a sufficiently large quantity of skutterudite material for module fabrication for our third and final prototype. Our TEG#3 is the first of its kind to contain state-of-the-art skutterudite-based TE modules to be installed and tested on a production vehicle. The design, which consisted of 24 skutterudite modules and 18 Bi-Te modules, attempted to optimize electrical power generation by using these two kinds of TE modules that have their peak performance temperatures matched to the actual temperature profile of the TEG during operation. The performance of TEG#3 was limited by the maximum temperature allowable for the Bi-Te TE modules located in the colder end of the TEG, resulting in the operating temperature for the skutterudite modules to be considerably below optimum. We measured the power output for (1) the complete TEG (25 Watts) and (2) an individual TE module series string (1/3 of the TEG) operated at a 60°C higher temperature (19 Watts). We estimate that under optimum operating temperature conditions, TEG#3 will generate about 235 Watts. With additional improvements in thermal and electrical interfaces, temperature homogeneity, and power conditioning, we estimate TEG#3 could deliver a power output of about 425 Watts.

New initiatives, trends and dilemmas for the Brazilian automotive industry: the case of Inovar Auto and its impacts on electromobility in Brazil  

Science Journals Connector (OSTI)

In the mid 2012, the Brazilian Government established the bases of a new industrial policy for the automotive sector. Under the acronym Inovar Auto, the complete name unfolds: programme for fostering technological innovation and densification of the automotive productive chain. This paper intends to detail and to analyse this programme, highlighting its weaknesses and strengths. With this, a comparison is to be made between previous initiatives and the one now starting. The authors also intend to analyse if and how the development of technologies associated to the electric car will effectively be fostered by the Inovar Auto, given that it is a technology pointing towards the future of the industry and does not yet count on leading technologies in world terms which, in theory, may pave the way for inserting Brazil in this market.

Visualization of the Invisible, Explanation of the Unknown, Ruggedization of the Unstable: Sensitivity Analysis, Virtual Tryout and Robust Design through Systematic Stochastic Simulation  

Science Journals Connector (OSTI)

In the past decade sheet metal forming simulation became a well established tool to predict the formability of parts. In the automotive industry this has enabled significant reduction in the cost and time for vehicle design and development and has helped to improve the quality and performance of vehicle parts. However production stoppages for troubleshooting and unplanned die maintenance as well as production quality fluctuations continue to plague manufacturing cost and time. The focus therefore has shifted in recent times beyond mere feasibility to robustness of the product and process being engineered. Ensuring robustness is the next big challenge for the virtual tryout / simulation technology.

System dynamics analysis of energy usage: case studies in automotive manufacturing  

Science Journals Connector (OSTI)

Our life is strongly linked with the usage of natural resources. With increase in world population and welfare there is an increasing global demand for raw material. Energy is a necessity in everyday life and is often generated using non-renewable natural resources which are finite. Manufacturing is one of the largest energy and material resource consumers. There is great concern about minimising consumption of energy in manufacturing industry to sustain the natural carrying capacity of the ecosystem. This is one of the challenges in today's industrial world. The paper presents the application of system dynamics theory for modelling and simulation of complex manufacturing processes. The simulations help to understand the intricate nature of the interrelation of process parameter and to make sound decision about minimising the energy losses. Two case studies are presented, one in cylinder head casting processes and the other in crankshaft machining. The developed models provide an insight into how to select critical operations and to identify the effect of various parameters on the energy consumption. Also, the models help to understand how changes of parameters over time affect the behaviour of energy changes. The outcome of this research enables the company to identify potential avenues to minimise energy usage and offers a decision support tool.

Model based design of an automotive-scale, metal hydride hydrogen storage system.  

SciTech Connect

Sandia and General Motors have successfully designed, fabricated, and experimentally operated a vehicle-scale hydrogen storage system using the complex metal hydride sodium alanate. Over the 6 year project, the team tackled the primary barriers associated with storage and delivery of hydrogen including mass, volume, efficiency and cost. The result was the hydrogen storage demonstration system design. The key technologies developed for this hydrogen storage system include optimal heat exchange designs, thermal properties enhancement, a unique catalytic hydrogen burner and energy efficient control schemes. The prototype system designed, built, and operated to demonstrate these technologies consists of four identical hydrogen storage modules with a total hydrogen capacity of 3 kg. Each module consists of twelve stainless steel tubes that contain the enhanced sodium alanate. The tubes are arranged in a staggered, 4 x 3 array and enclosed by a steel shell to form a shell and tube heat exchanger. Temperature control during hydrogen absorption and desorption is accomplished by circulating a heat transfer fluid through each module shell. For desorption, heat is provided by the catalytic oxidation of hydrogen within a high efficiency, compact heat exchanger. The heater was designed to transfer up to 30 kW of heat from the catalytic reaction to the circulating heat transfer fluid. The demonstration system module design and the system control strategies were enabled by experiment-based, computational simulations that included heat and mass transfer coupled with chemical kinetics. Module heat exchange systems were optimized using multi-dimensional models of coupled fluid dynamics and heat transfer. Chemical kinetics models were coupled with both heat and mass transfer calculations to design the sodium alanate vessels. Fluid flow distribution was a key aspect of the design for the hydrogen storage modules and computational simulations were used to balance heat transfer with fluid pressure requirements. An overview of the hydrogen storage system will be given, and examples of these models and simulation results will be described and related to component design. In addition, comparisons of demonstration system experimental results to model predictions will be reported.

Mass balance for \\{POPs\\} in a real scale fluidized bed combustor co-incinerating automotive shredder residue  

Science Journals Connector (OSTI)

The European directive 2000/53/EC implies a “reuse and recovery” rate for end-of-life vehicles (ELVs) of 95% to be reached by the year 2015. One of the options to increase the actual average European “reuse and recovery” rate of approximately 78% (EU 15, 2008) is incineration of automotive shredder residue (ASR) with energy-recovery. The mass balance and the congener fingerprints for PCDD/Fs, dioxin-like PCBs, \\{PCBs\\} and \\{PAHs\\} in a real scale fluidized bed combustor (FBC) incinerating 25% ASR with 25% refuse derived fuel (RDF) and 50% waste water treatment sludge (WWT sludge) were investigated. The PCDD/F, dioxin-like PCB, PCB and PAH concentrations in this input waste mix were more than hundred times higher than in the usual waste feed of the incinerator (30% RFD and 70% WWT sludge). In the outputs of the FBC, however, the concentrations of these POP groups were comparable or only slightly higher than in the outputs generated during the incineration of the usual waste feed. The considered \\{POPs\\} in the waste were destroyed efficiently and the formation of new \\{POPs\\} during cooling of the flue gas appeared to a large extent independent of the POP concentrations in the incinerated waste.

Thermal model design and analysis of the high-power LED automotive headlight cooling device  

Science Journals Connector (OSTI)

Abstract A study of the thermal performance of conventional plate-fin heat sinks and novel cooling device integrated with heat conductive plates (HCPS) for the application in high-power LED headlight was presented. The thermal resistance network model was built to analyze the factors which have impacts on the junction temperature. The analyses were based on the experiment combined with computations using the CFD software FloEFD. The prediction results were validated with the experimental one. Details of the heat transfer performance, particularly the temperature distribution of the LED module and lampshell, as well as the effect of HCPS length on the system thermal resistance and the average heat transfer coefficient were obtained. Since it could make some distance between the heat sink and the lampshell, the average surface convective heat transfer coefficient had been improved and the overall external thermal resistance was reduced effectively. The effects of the simulated ambient temperature, chip package depth, inclination angles and fan rotate speeds on the junction temperature were also examined. Results indicated that the airflow was weakened as the chip package depth increased. In addition, with the presence of the enforced velocity airflow, the junction temperature decreased gradually from 116.61 °C to 78.05 °C.

Digestion Simulations Digestion Simulations Name: Lisa Location: N/A Country: N/A Date: N/A Question: My 5th grade students are beginning an experiment next week and their hypothesis involves edibility(edibleness?). Is there a way to replicate the stomach in, say, a bottle?? Are there ways to test for edibleness(?) without actually ingesting the experiment yourself? Replies: I would not recommend the idea of a bottle stomach. The stomach digests only proteins anyway with HCl [pH 1.0] which is very, very strong acid that will burn seriously if in contact with skin. The intestine is just as much responsible for digestion of lipids [bile], carbohydrates and remaining proteins using enzymes, many of these you do not want to be handling, let alone purchase. As a high school teacher, I have lab exercises dealing with digestion, but I can not recommend any of these unless you are set up with a functional science laboratory and all the safety equipment necessary.

Repurposing lithium-ion batteries at the end of useful life Repurposing lithium-ion batteries at the end of useful life in electric drive vehicles could eliminate owners' disposal concerns and offer low-cost energy storage for certain applications. Increasing the number of plug-in electric drive vehicles (PEVs) is one major strategy for reduc- ing the nation's oil imports and greenhouse gas emissions. However, the high up-front cost and end-of-service disposal concerns of their lithium-ion (Li-ion) batteries could impede the proliferation of such vehicles.

Battery Lifetime Analysis and Simulation Tool (BLAST) Documentation  

SciTech Connect

The deployment and use of lithium-ion batteries in automotive and stationary energy storage applications must be optimized to justify their high up-front costs. Given that batteries degrade with use and storage, such optimizations must evaluate many years of operation. As the degradation mechanisms are sensitive to temperature, state-of-charge histories, current levels, and cycle depth and frequency, it is important to model both the battery and the application to a high level of detail to ensure battery response is accurately predicted. To address these issues, the National Renewable Energy Laboratory has developed the Battery Lifetime Analysis and Simulation Tool (BLAST) suite of tools. This suite of tools pairs NREL's high-fidelity battery degradation model with a battery electrical and thermal performance model, application-specific electrical and thermal performance models of the larger system (e.g., an electric vehicle), application-specific system use data (e.g., vehicle travel patterns and driving data), and historic climate data from cities across the United States. This provides highly realistic, long-term predictions of battery response and thereby enables quantitative comparisons of varied battery use strategies.

Modeling & Simulation - GCTool  

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

GCTool Computer Model Helps Focus Fuel Cell Vehicle Research Somewhere near Detroit, an automotive engineer stares at the ceiling, wondering how to squeeze 1% more efficiency out of the fuel cell reformer she's been working on. Never mind 5% more from the next component on her list. Computer software, such as Argonne's GCTool, lets designers "try out" different system configurations, without the expense and delays of actually building numerous prototypes. Our engineer could learn that she's been worrying about the wrong thing. Argonne systems analysts have shown that in fuel cell systems for vehicles, more is not always better. For example, increasing the efficiency of the fuel processor (the component that converts hydrocarbon fuel into hydrogen for the fuel cell) may actually lower the overall system efficiency. "They go in opposite directions. You can make the fuel processor more efficient, but that's because you're stealing energy from somewhere else in the system," says Argonne's Romesh Kumar, who leads Argonne's fuel cell modeling efforts.

Assessment of ground vibration impact from automotive and transit sources on future biotechnology research center using finite element analysis (FEA)  

Science Journals Connector (OSTI)

A new science and biotechnology research center was to be built in a metropolitan industrial area. There was concern that ground vibration from a nearby freeway street traffic and trains on an adjacent railroad would impact vibration sensitive research equipment inside the building. Ground vibration was measured at the project site prior to construction. Finite Element Analysis(FEA) was used to develop a computer simulation of the building structure using the measured ground vibration as input to the FEAmodel. The study determined the building floor vibration due to exterior sources would achieve the project’s criteria for the building structure as designed.

The hydrogen value chain: applying the automotive role model of the hydrogen economy in the aerospace sector to increase performance and reduce costs  

Science Journals Connector (OSTI)

Hydrogen will assume a key role in Europe's effort to adopt its energy dependent society to satisfy its needs without releasing vast amounts of greenhouse gases. The paradigm shift is so paramount that one speaks of the “Hydrogen Economy”, as the energy in this new and ecological type of economy is to be distributed by hydrogen. However, H2 is not a primary energy source but rather an energy carrier, a means of storing, transporting and distributing energy, which has to be generated by other means. Various H2 storage methods are possible; however industries' favourite is the storage of gaseous hydrogen in high pressure tanks. The biggest promoter of this storage methodology is the automotive industry, which is currently preparing for the generation change from the fossil fuel internal combustion engines to hydrogen based fuel cells. The current roadmaps foresee a market roll-out by 2015, when the hydrogen supply infrastructure is expected to have reached a critical mass. The hydrogen economy is about to take off as being demonstrated by various national mobility strategies, which foresee several millions of electric cars driving on the road in 2020. Fuel cell cars are only one type of “electric car”, battery electric as well as hybrid cars – all featuring electric drive trains – are the others. Which type of technology is chosen for a specific application depends primarily on the involved energy storage and power requirements. These considerations are very similar to the ones in the aerospace sector, which had introduced the fuel cell already in the 1960s. The automotive sector followed only recently, but has succeeded in moving forward the technology to a level, where the aerospace sector is starting considering to spin-in terrestrial hydrogen technologies into its technology portfolio. Target areas are again high power/high energy applications like aviation, manned spaceflight and exploration missions, as well as future generation high power telecommunication satellites. Similar trends can be expected in the future for RADAR Earth Observation satellites and space infrastructure concepts of great scale. This paper examines current activities along the hydrogen value chain, both in the terrestrial and the aerospace sector. A general assessment of the synergy potential is complemented by a thorough analysis of specific applications serving as role models like a lunar manned base or pressurised rover, an aircraft APU or a high power telecommunications satellite. Potential performance improvements and cost savings serve as key performance indicators in these comparisons and trade-offs.

Assessment of Computer Simulation Software and Process Data for High Pressure Die Casting of Magnesium  

SciTech Connect

Computer software for the numerical simulation of solidification and mold filling is an effective design tool for cast structural automotive magnesium components. A review of commercial software capabilities and their validation procedures was conducted. Aside form the software assessment, the program addressed five main areas: lubricant degradation, lubricant application, gate atomization, and heat transfer at metal mold interfaces. A test stand for lubricant application was designed. A sensor was used for the direct measurement of heat fluxes during lubricant application and casting solidification in graphite molds. Spray experiments were conducted using pure deionized water and commercial die lubricants. The results show that the sensor can be used with confidence for measuring heat fluxes under conditions specific to the die lube application. The data on heat flux was presented in forms suitable for use in HPDC simulation software. Severe jet breakup and atomization phenomena are likely to occur due to high gate velocities in HPDC. As a result of gate atomization, droplet flow affects the mold filling pattern, air entrapment, skin formation, and ensuing defects. Warm water analogue dies were designed for obtaining experimental data on mold filling phenomena. Data on break-up jet length, break-up pattern, velocities, and droplet size distribution were obtained experimentally and was used to develop correlations for jet break-up phenomena specific to die casting gate configurations.

Destruction and formation of PCDD/Fs in a fluidised bed combustor co-incinerating automotive shredder residue with refuse derived fuel and wastewater treatment sludge  

Science Journals Connector (OSTI)

During an eight day trial automotive shredder residue (ASR) was added to the usual waste feed of a Fluidized Bed Combustor (FBC) for waste-to-energy conversion; the input waste mix consisted of 25% ASR, 25% refuse-derived fuel (RDF) and 50% wastewater treatment (WWT) sludge. All inputs and outputs were sampled and the concentration of the 17 PCDD/Fs with TEF-values was determined in order to obtain “PCDD/F fingerprints”. The ASR contained approximately 9000 ng PCDD/Fs/kgDW, six times more than the RDF and 10 times more than the WWT sludge. The fingerprint of ASR and RDF was dominated by HpCDD and OCDD, which accounted for 90% of the total PDDD/F content, whereas the WWT sludge contained relatively more HpCDFs and OCDF (together 70%). The flue gas cleaning residue (FGCR) and fly and boiler ash contained approximately 30,000 and 2500 ng PCDD/Fs/kgDW, respectively. The fingerprints of these outputs were also dominated by HpCDFs and OCDF. The bottom ash contained only OCDD and OCDF, in total 8 ng PCDD/Fs/kgDW. From the comparison of the bottom ash fingerprints with the fingerprints of the other output fractions and of the inputs, it could be concluded that the PCDD/Fs in the waste were destroyed and new PCDD/Fs were formed in the post combustion process by de novo synthesis. During the ASR-co-incineration, the PCDD/F congener concentrations in the fly and boiler ash, FGCR and flue gas were 1.25–10 times higher compared to the same output fractions generated during incineration of the usual waste mix (70% RDF and 30% WWT sludge). The concentration of the higher chlorinated PCDD/Fs increased most. As these congeners have the lowest TEF-factors, the total PCDD/F output, expressed in kg TEQ/year, of the FBC did not increase significantly when ASR was co-incinerated. Due to the relatively high copper levels in the ASR, the copper concentrations in the \\{FBCs\\} outputs increased. As copper catalysis the de novo syntheses, this could explain the increase in PCDD/F concentrations in these outputs.

Simulation of LMFBR  

SciTech Connect

The title of this session is taken to imply the system-wide thermohydraulic simulation of liquid metal fast breeder reactors (LMFBR). One is interested in predicting the temperatures, pressures, and the coolant flow rates throughout the entire plant including the reactor core, the primary and secondary sodium heat transport circuits, the steam generating system as well as other auxiliary circuits. Such a simulation is needed for (1) scoping studies (i.e., in the pre-design phase of a plant), (2) detailed design development, (3) the safety analysis (post-design development phase), and (4) the operator training and plant operation. This session emphasizes the simulation of LMFBRs for only two key categories of transients: operational disturbances or events and the post-shutdown heat removal.

Computing Stuttering Simulations  

E-Print Network (OSTI)

Stuttering bisimulation is a well-known behavioral equivalence that preserves CTL-X, namely CTL without the next-time operator X. Correspondingly, the stuttering simulation preorder induces a coarser behavioral equivalence that preserves the existential fragment ECTL-{X,G}, namely ECTL without the next-time X and globally G operators. While stuttering bisimulation equivalence can be computed by the well-known Groote and Vaandrager's [1990] algorithm, to the best of our knowledge, no algorithm for computing the stuttering simulation preorder and equivalence is available. This paper presents such an algorithm for finite state systems.

Enabling immersive simulation.  

SciTech Connect

The object of the 'Enabling Immersive Simulation for Complex Systems Analysis and Training' LDRD has been to research, design, and engineer a capability to develop simulations which (1) provide a rich, immersive interface for participation by real humans (exploiting existing high-performance game-engine technology wherever possible), and (2) can leverage Sandia's substantial investment in high-fidelity physical and cognitive models implemented in the Umbra simulation framework. We report here on these efforts. First, we describe the integration of Sandia's Umbra modular simulation framework with the open-source Delta3D game engine. Next, we report on Umbra's integration with Sandia's Cognitive Foundry, specifically to provide for learning behaviors for 'virtual teammates' directly from observed human behavior. Finally, we describe the integration of Delta3D with the ABL behavior engine, and report on research into establishing the theoretical framework that will be required to make use of tools like ABL to scale up to increasingly rich and realistic virtual characters.

FASTBUS simulation tools  

SciTech Connect

A generalized model of a FASTBUS master is presented. The model is used with simulation tools to aid in the specification, design, and production of FASTBUS slave modules. The model provides a mechanism to interact with the electrical schematics and software models to predict performance. The model is written in the IEEE std 1076-1987 hardware description language VHDL. A model of the ATC logic is also presented. VHDL was chosen to provide portability to various platforms and simulation tools. The models, in conjunction with most commercially available simulators, will perform all of the transactions specified in IEEE std 960-1989. The models may be used to study the behavior of electrical schematics and other software models and detect violations of the FASTBUS protocol. For example, a hardware design of a slave module could be studied, protocol violations detected and corrected before committing money to prototype development. The master model accepts a stream of high level commands from an ASCII file to initiate FASTBUS transactions. The high level command language is based on the FASTBUS standard routines listed in IEEE std 1177-1989. Using this standard-based command language to direct the model of the master, hardware engineers can simulate FASTBUS transactions in the language used by physicists and programmers to operate FASTBUS systems. 15 refs., 6 figs.

Efficient simulation of press hardening process through integrated structural and CFD analyses  

SciTech Connect

Press hardened steel parts are being increasingly used in automotive structures for their higher strength to meet safety standards while reducing vehicle weight to improve fuel consumption. However, manufacturing of sheet metal parts by press hardening process to achieve desired properties is extremely challenging as it involves complex interaction of plastic deformation, metallurgical change, thermal distribution, and fluid flow. Numerical simulation is critical for successful design of the process and to understand the interaction among the numerous process parameters to control the press hardening process in order to consistently achieve desired part properties. Until now there has been no integrated commercial software solution that can efficiently model the complete process from forming of the blank, heat transfer between the blank and tool, microstructure evolution in the blank, heat loss from tool to the fluid that flows through water channels in the tools. In this study, a numerical solution based on Altair HyperWorks® product suite involving RADIOSS®, a non-linear finite element based structural analysis solver and AcuSolve®, an incompressible fluid flow solver based on Galerkin Least Square Finite Element Method have been utilized to develop an efficient solution for complete press hardening process design and analysis. RADIOSS is used to handle the plastic deformation, heat transfer between the blank and tool, and microstructure evolution in the blank during cooling. While AcuSolve is used to efficiently model heat loss from tool to the fluid that flows through water channels in the tools. The approach is demonstrated through some case studies.

Utilization of Common Automotive Three-Way NO{sub x} Reduction Catalyst for Managing Off- Gas from Thermal Treatment of High-Nitrate Waste - 13094  

SciTech Connect

Studsvik's Thermal Organic Reduction (THOR) steam reforming process has been tested and proven to effectively treat radioactive and hazardous wastes streams with high nitrate contents to produce dry, stable mineral products, while providing high conversion (>98%) of nitrates and nitrites directly to nitrogen gas. However, increased NO{sub x} reduction may be desired for some waste streams under certain regulatory frameworks. In order to enhance the NO{sub x} reduction performance of the THOR process, a common Three-Way catalytic NO{sub x} reduction unit was installed in the process gas piping of a recently completed Engineering Scale Technology Demonstration (ESTD). The catalytic DeNO{sub x} unit was located downstream of the main THOR process vessel, and it was designed to catalyze the reduction of residual NO{sub x} to nitrogen gas via the oxidation of the hydrogen, carbon monoxide, and volatile organic compounds that are inherent to the THOR process gas. There was no need for auxiliary injection of a reducing gas, such as ammonia. The unit consisted of four monolith type catalyst sections positioned in series with a gas mixing section located between each catalyst section. The process gas was monitored for NO{sub x} concentration upstream and downstream of the catalytic DeNO{sub x} unit. Conversion efficiencies ranged from 91% to 97% across the catalytic unit, depending on the composition of the inlet gas. Higher concentrations of hydrogen and carbon monoxide in the THOR process gas increased the NO{sub x} reduction capability of the catalytic DeNO{sub x} unit. The NO{sub x} destruction performance of THOR process in combination with the Three-Way catalytic unit resulted in overall system NO{sub x} reduction efficiencies of greater than 99.9% with an average NO{sub x} reduction efficiency of 99.94% for the entire demonstration program. This allowed the NO{sub x} concentration in the ESTD exhaust gas to be maintained at less than 40 parts per million (ppm), dry basis with an average concentration of approximately 17 ppm, dry basis. There were no signs of catalyst deactivation throughout the 6 day demonstration program, even under the high steam (>50%) content and chemically reducing conditions inherent to the THOR process. Utilization of the common Three-Way automotive catalyst may prove to be a cost effective method for improving NO{sub x} emissions from thermal treatment processes that utilize similar processing conditions. This paper will discuss the details of the implementation and performance of the Three-Way catalytic DeNO{sub x} unit at the THOR ESTD, as well as a discussion of future work to determine the long-term durability of the catalyst in the THOR process.

PEBBLES Mechanics Simulation Speedup  

SciTech Connect

Pebble bed reactors contain large numbers of spherical fuel elements arranged randomly. Determining the motion and location of these fuel elements is required for calculating certain parameters of pebble bed reactor operation. These simulations involve hundreds of thousands of pebbles and involve determining the entire core motion as pebbles are recirculated. Single processor algorithms for this are insufficient since they would take decades to centuries of wall-clock time. This paper describes the process of parallelizing and speeding up the PEBBLES pebble mechanics simulation code. Both shared memory programming with the Open Multi-Processing API and distributed memory programming with the Message Passing Interface API are used in simultaneously in this process. A new shared memory lock-less linear time collision detection algorithm is described. This method allows faster detection of pebbles in contact than generic methods. These combine to make full recirculations on AVR sized reactors possible in months of wall clock time.

The Simulation Intranet Architecture  

SciTech Connect

The Simdarion Infranet (S1) is a term which is being used to dcscribc one element of a multidisciplinary distributed and distance computing initiative known as DisCom2 at Sandia National Laboratory (http ct al. 1998). The Simulation Intranet is an architecture for satisfying Sandia's long term goal of providing an end- to-end set of scrviccs for high fidelity full physics simu- lations in a high performance, distributed, and distance computing environment. The Intranet Architecture group was formed to apply current distributed object technologies to this problcm. For the hardware architec- tures and software models involved with the current simulation process, a CORBA-based architecture is best suited to meet Sandia's needs. This paper presents the initial desi-a and implementation of this Intranct based on a three-tier Network Computing Architecture(NCA). The major parts of the architecture include: the Web Cli- ent, the Business Objects, and Data Persistence.

SATCOM constellation power simulation  

SciTech Connect

Three basic variables directly impact the power and energy generated by the SATCOM satellite constellation and its individual Space Vehicles (SVs). They are (1) telecommunications traffic patterns, (2) network resource management controllables, and (3) system hardware and software performance. This power simulation has verified the robustness of the telecommunications architecture. It has validated the onboard resource allocation process from an SV and network level power and energy perspective. The analyses have led to development of operational procedures that prevent SV node outages, and maximize network telecommunication traffic capacity. The program objective is to optimize overall system operation, availability and quality of service. Achieving this goal requires a thorough understanding of the Electrical Power Subsystem and its interfaces. The EPS simulation model analyzes network level performance by evaluating requirement compliance in the expected operating environments. Specifically, the simulation tool evaluates different design approaches and network operational strategies from a power and energy perspective. As a result, optimal load management solutions will be implemented both on-board the SV and via ground station directed resource allocation strategies.

This requires developing a predictive integrated simulation capability for magnetically-confined fusion plasmas that are properly validated against experiments in regimes relevant for producing practical fusion energy. Specific institutional goal of the New York University was to participate in the planning of the edge integrated simulation, with emphasis on the usage of large scale HPCs, in connection with the SciDAC CPES project which the PI was leading. New York University successfully completed its mission by participating in the various planning activities, including the edge physics integration, the edge science drivers, and the mathematical verification. The activity resulted in the combined report that can be found in http://www.pppl.gov/fsp/Overview.html. Participation and presentations as part of this project are listed in a separation file.

Plasma theory and simulation research  

SciTech Connect

Our research group uses both theory and simulation as tools in order to increase the understanding of instabilities, heating, diffusion, transport and other phenomena in plasmas. We also work on the improvement of simulation, both theoretically and practically. Our focus has been more and more on the plasma edge (the sheath''), interactions with boundaries, leading to simulations of whole devices (someday a numerical tokamak).

A new smoothed particle hydrodynamics non-Newtonian model for friction stir welding: Process modeling and simulation of microstructure evolution in a magnesium alloy  

SciTech Connect

We present a new smoothed particle hydrodynamics (SPH) model for friction stir welding (FSW). FSW has found broad commercial application in the marine, aerospace, rail and automotive industries. Development of the FSW process for each new application, however, has remained largely empirical. Few established numerical modeling techniques have been developed that can explain and predict important features of the process physics involved in FSW. This is particularly true in the areas of material ?ow, mixing mechanisms, and void formation. In this paper we present a novel modeling approach to simulate FSW that may have signi?cant advantages over current ?nite element or ?nite di?erence based methods. Unlike traditional grid-based methods, Lagrangian particle methods such as SPH can simulate the dynamics of interfaces, large material deformations, and the material’s strain and temperature history without employing complex tracking schemes. Three-dimensional simulations of FSW on AZ31 Mg alloy are presented. Numerical results are in a close quantitative agreement with experimental observations.

Simulating Cosmic Reionization  

E-Print Network (OSTI)

The Cosmic Dark Ages and the Epoch of Reionization constitute a crucial missing link in our understanding of the evolution of the intergalactic medium and the formation and evolution of galaxies. Due to the complex nature of this global process it is best studied through large-scale numerical simulations. This presents considerable computational challenges. The dominant contributors of ionizing radiation were dwarf galaxies. These tiny galaxies must be resolved in very large cosmological volumes in order to derive their clustering properties and the corresponding observational signatures correctly, which makes this one of the most challenging problems of numerical cosmology. We have recently performed the largest and most detailed simulations of the formation of early cosmological large-scale structures and their radiative feedback leading to cosmic reionization. This was achieved by running extremely large (up to 29 billion-particle) N-body simulations of the formation of the Cosmic Web, with enough particles and sufficient force resolution to resolve all the galactic halos with total masses larger than 10^8 Solar masses in computational volumes of up to (163 Mpc)^3. These results were then post-processed by propagating the ionizing radiation from all sources by using fast and accurate ray-tracing radiative transfer method. Both of our codes are parallelized using a combination of MPI and OpenMP and to this date have been run efficiently on up to 2048 cores (N-body) and up to 10000 cores (radiative transfer) on the newly-deployed Sun Constellation Linux Cluster at the Texas Advanced Computing Center. In this paper we describe our codes, parallelization strategies, scaling and some preliminary scientific results. (abridged)

Plasma Simulation Program  

SciTech Connect

Many others in the fusion energy and advanced scientific computing communities participated in the development of this plan. The core planning team is grateful for their important contributions. This summary is meant as a quick overview the Fusion Simulation Program's (FSP's) purpose and intentions. There are several additional documents referenced within this one and all are supplemental or flow down from this Program Plan. The overall science goal of the DOE Office of Fusion Energy Sciences (FES) Fusion Simulation Program (FSP) is to develop predictive simulation capability for magnetically confined fusion plasmas at an unprecedented level of integration and fidelity. This will directly support and enable effective U.S. participation in International Thermonuclear Experimental Reactor (ITER) research and the overall mission of delivering practical fusion energy. The FSP will address a rich set of scientific issues together with experimental programs, producing validated integrated physics results. This is very well aligned with the mission of the ITER Organization to coordinate with its members the integrated modeling and control of fusion plasmas, including benchmarking and validation activities. [1]. Initial FSP research will focus on two critical Integrated Science Application (ISA) areas: ISA1, the plasma edge; and ISA2, whole device modeling (WDM) including disruption avoidance. The first of these problems involves the narrow plasma boundary layer and its complex interactions with the plasma core and the surrounding material wall. The second requires development of a computationally tractable, but comprehensive model that describes all equilibrium and dynamic processes at a sufficient level of detail to provide useful prediction of the temporal evolution of fusion plasma experiments. The initial driver for the whole device model will be prediction and avoidance of discharge-terminating disruptions, especially at high performance, which are a critical impediment to successful operation of machines like ITER. If disruptions prove unable to be avoided, their associated dynamics and effects will be addressed in the next phase of the FSP.

Unipolar arc simulation device  

SciTech Connect

We describe a simple laboratory device for establishing a vacuum arc plasma discharge that can serve to simulate a unipolar arc. The technique makes use of a triggered vacuum arc plasma gun to generate a plasma plume that in turn causes breakdown of a secondary discharge. The device is in fact a secondary vacuum arc discharge that is triggered by a primary vacuum arc discharge, with some of the features of the secondary plasma discharge having similarities with a unipolar arc configuration. Here we describe the experimental setup and outline how the device can be used for some areas of unipolar arc materials research. [copyright] [ital 1999 American Institute of Physics.

SEALING SIMULATED LEAKS  

SciTech Connect

This report details the testing equipment, procedures and results performed under Task 7.2 Sealing Simulated Leaks. In terms of our ability to seal leaks identified in the technical topical report, Analysis of Current Field Data, we were 100% successful. In regards to maintaining seal integrity after pigging operations we achieved varying degrees of success. Internal Corrosion defects proved to be the most resistant to the effects of pigging while External Corrosion proved to be the least resistant. Overall, with limitations, pressure activated sealant technology would be a viable option under the right circumstances.

Gyrokinetic large eddy simulations  

SciTech Connect

The large eddy simulation approach is adapted to the study of plasma microturbulence in a fully three-dimensional gyrokinetic system. Ion temperature gradient driven turbulence is studied with the GENE code for both a standard resolution and a reduced resolution with a model for the sub-grid scale turbulence. A simple dissipative model for representing the effect of the sub-grid scales on the resolved scales is proposed and tested. Once calibrated, the model appears to be able to reproduce most of the features of the free energy spectra for various values of the ion temperature gradient.

LSST beam simulator  

Science Journals Connector (OSTI)

It is always important to test new imagers for a mosaic camera before device acceptance and constructing the mosaic. This is particularly true of the LSST CCDs due to the fast beam illumination: at long wavelengths there can be significant beam divergence (defocus) inside the silicon because of the long absorption length for photons near the band gap. Moreover, realistic sky scenes need to be projected onto the CCD focal plane Thus, we need to design and build an f/1.2 re-imaging system. The system must simulate the entire LSST1 operation, including a sky with galaxies and stars with approximately black-body spectra superimposed on a spatially diffuse night sky emission with its complex spectral features.

Dynamic simulation of Odoo  

Science Journals Connector (OSTI)

Abstract The thermal habits of Odoo were examined and energy consumption data were also predicted. Special tests were performed for the time of the competition, and whole year was also analysed. The climatic data were of Madrid as the competition took place there. The modelling environment was MATLAB's Simulink with a built-in module of Simscape. It is for especially examining thermal behaviours. MATLAB itself is capable of solving differential equations by time, for this reason dynamic simulations can be performed. First the building structure was created, and then the heatflows affecting the internal temperature were added. In this paper detailed process of creating the model is presented, and some results are discussed, including some possibilities of further improvements.

This paper describes the construction of an infrastructure for global peace gaming, in particular on the issue of environmental and sustainable development in Third World countries. The gaming is intended to train would-be decision-makers in crisis management, conflict resolution and negotiation techniques. Experience shows that the expertise necessary to participate in peace games does not exist in many parts of the world. To help educate future participants, and to promote the cause of peace by enhancing exchanges of education and joint research, the Global Systems Analysis and Simulation (GLOSAS) Project is attempting to create a global (electronic) university consortium. This paper provides a brief account of the steps taken over the past 12 years which have led to the development of the Global University now being organised to meet the challenge of global issues both today and in the 21st century.

MJO Simulation Diagnostics  

SciTech Connect

The Madden-Julian Oscillation (MJO) interacts with, and influences, a wide range of weather and climate phenomena (e.g., monsoons, ENSO, tropical storms, mid-latitude weather), and represents an important, and as yet unexploited, source of predictability at the subseasonal time scale. Despite the important role of the MJO in our climate and weather systems, current global circulation models (GCMs) exhibit considerable shortcomings in representing this phenomenon. These shortcomings have been documented in a number of multi-model comparison studies over the last decade. However, diagnosis of model performance has been challenging, and model progress has been difficult to track, due to the lack of a coherent and standardized set of MJO diagnostics. One of the chief objectives of the US CLIVAR MJO Working Group is the development of observation-based diagnostics for objectively evaluating global model simulations of the MJO in a consistent framework. Motivation for this activity is reviewed, and the intent and justification for a set of diagnostics is provided, along with specification for their calculation, and illustrations of their application. The diagnostics range from relatively simple analyses of variance and correlation, to more sophisticated space-time spectral and empirical orthogonal function analyses. These diagnostic techniques are used to detect MJO signals, to construct composite life-cycles, to identify associations of MJO activity with the mean state, and to describe interannual variability of the MJO.

MESOSCALE SIMULATIONS OF POWDER COMPACTION  

SciTech Connect

Mesoscale 3D simulations of shock compaction of metal and ceramic powders have been performed with an Eulerian hydrocode GEODYN. The approach was validated by simulating a well-characterized shock compaction experiment of a porous ductile metal. Simulation results using the Steinberg material model and handbook values for solid 2024 aluminum showed good agreement with experimental compaction curves and wave profiles. Brittle ceramic materials are not as well studied as metals, so a simple material model for solid ceramic (tungsten carbide) has been calibrated to match experimental compaction curves. Direct simulations of gas gun experiments with ceramic powders have been performed and showed good agreement with experimental data. The numerical shock wave profile has same character and thickness as that measured experimentally using VISAR. The numerical results show reshock states above the single-shock Hugoniot line as observed in experiments. We found that for good quantitative agreement with experiments 3D simulations are essential.

High-Performance Control of Two Three-Phase Permanent-Magnet Synchronous Machines in an Integrated Drive for Automotive Applications  

SciTech Connect

The closed-loop control of an integrated dual AC drive system is presented to control two three-phase permanent-magnet motors. A five-leg inverter is employed in the drive system; three of the inverter legs are for a main traction motor, but only two are needed for a three-phase auxiliary motor by utilizing the neutral point of the traction motor. An integrated drive with reduced component count is therefore achieved by eliminating one inverter leg and its gate drivers. A modified current control scheme based on the rotor flux orientation principle is presented. Simulation and experimental results are included to verify the independent control capability of the integrated drive.

Inductive electromagnetic launchers, or coilguns, use discrete solenoidal coils to accelerate a coaxial conductive armature. To date, Sandia has been using an internally developed code, SLINGSHOT, as a point-mass lumped circuit element simulation tool for modeling coilgun behavior for design and verification purposes. This code has shortcomings in terms of accurately modeling gun performance under stressful electromagnetic propulsion environments. To correct for these limitations, it was decided to attempt to closely couple two Sandia simulation codes, Xyce and ALEGRA, to develop a more rigorous simulation capability for demanding launch applications. This report summarizes the modifications made to each respective code and the path forward to completing interfacing between them.

Adaptive Sampling in Hierarchical Simulation  

SciTech Connect

We propose an adaptive sampling methodology for hierarchical multi-scale simulation. The method utilizes a moving kriging interpolation to significantly reduce the number of evaluations of finer-scale response functions to provide essential constitutive information to a coarser-scale simulation model. The underlying interpolation scheme is unstructured and adaptive to handle the transient nature of a simulation. To handle the dynamic construction and searching of a potentially large set of finer-scale response data, we employ a dynamic metric tree database. We study the performance of our adaptive sampling methodology for a two-level multi-scale model involving a coarse-scale finite element simulation and a finer-scale crystal plasticity based constitutive law.

A Parallel Quantum Computer Simulator  

E-Print Network (OSTI)

A Quantum Computer is a new type of computer which can efficiently solve complex problems such as prime factorization. A quantum computer threatens the security of public key encryption systems because these systems rely on the fact that prime factorization is computationally difficult. Errors limit the effectiveness of quantum computers. Because of the exponential nature of quantum com puters, simulating the effect of errors on them requires a vast amount of processing and memory resources. In this paper we describe a parallel simulator which accesses the feasibility of quantum computers. We also derive and validate an analytical model of execution time for the simulator, which shows that parallel quantum computer simulation is very scalable.

Simulating Afterburn with LLNL Hydrocodes  

SciTech Connect

Presented here is a working methodology for adapting a Lawrence Livermore National Laboratory (LLNL) developed hydrocode, ALE3D, to simulate weapon damage effects when afterburn is a consideration in the blast propagation. Experiments have shown that afterburn is of great consequence in enclosed environments (i.e. bomb in tunnel scenario, penetrating conventional munition in a bunker, or satchel charge placed in a deep underground facility). This empirical energy deposition methodology simulates the anticipated addition of kinetic energy that has been demonstrated by experiment (Kuhl, et. al. 1998), without explicitly solving the chemistry, or resolving the mesh to capture small-scale vorticity. This effort is intended to complement the existing capability of either coupling ALE3D blast simulations with DYNA3D or performing fully coupled ALE3D simulations to predict building or component failure, for applications in National Security offensive strike planning as well as Homeland Defense infrastructure protection.
