Abstract:
Thermomagnetic heat engines were designed, constructed, and tested, where numbers of gadolinium (Gd) blocks were used to exploit low temperature waste heat. Gadolinium is a rare earth material whose magnetic property changes with temperature, altering between ferromagnetic and paramagnetic. A motion develops in the thermomagnetic heat engine as Gd blocks are exposed to different temperatures causing changes in their magnetic property. A change in the magnetic property of any Gd block is directly related to the resultant torque driving the thermomagnetic heat engine for power production. Among

Abstract:
The Stirling engine is capable of converting any source of thermal energy into kinetic energy, which makes it an attractive option for utilizing low-temperature sources such as geothermal or waste heat below 100 °C. However, at these low temperatures, the effects of losses are proportionally higher due to the lower thermal potential available. One such significant loss is excess dead volume, wherein a significant contributor is the heat exchangers. The heat exchangers must be selected to optimize power output by minimizing the dead volume loss while maximizing the heat transfer to and from the

Abstract:
In recent years, the interest in low-pollution and high-efficiency heat engines has been increasing due to the growing awareness of environmental protection, and power generation at relatively low temperatures, such as use of exhaust heat and sunlight, has been attracting attention. Compared with other heat engines, Stirling engine is very important because it can be driven by any heat source at low temperatures, such as exhaust heat, and it does not emit exhaust gas. In order to realize a more efficient Stirling engine, it is essential to design a heat exchange system that is suitable for eac

Large amounts of energy from heat sources such as waste-eat and geothermal energy are available worldwide but their potential for useful power-generation is largely untapped. This is because they are relatively low temperature difference (LTD) sources, in the range from 100 to 200 °C, and it is thermodynamically diffcult, for theoretical and practical reasons, to extract useful work at these temperatures.

Abstract:
Generally, the turbulent-flame velocity of natural gas is significantly lower than diesel in the combustion process, which results in the thermal loads of natural gas engines being significantly higher than those of diesel engines under the same stoichiometric condition without EGR. In this study, a heavy-duty natural gas engine is taken as the research object, which is used to measure the temperatures to analyze the heat transfer characteristics in the cylinder head water jacket around the valve bridges, under different speeds and loads, as well as different coolant temperatures and pressures

Abstract:
Condensation of gaseous fuel is investigated in a low temperature combustion engine fueled with double direct-injected diesel and premixed gasoline at two load conditions. Possible condensation is examined by considering real gas effects with the Peng-Robinson equation of state and assuming thermodynamic equilibrium of the two fuels. The simulations show that three representative condensation events are observed. The first two condensations are found in the spray some time after the two direct injections, when the evaporative cooling reduces the local temperature until phase separation occurs.

Abstract:
Adiabatics INC. with the support of U.S. Army Tank Automotive and Armaments Command has developed a new high temperature lubricant with additives package to work under the rigid regime of advanced Low Heat Rejection (LHR) diesel engine operating parameters. Using the newly developed high temperature lubricant on a laboratory tribology test bench and on a single cylinder LHR engine, the Army specified requirements of 410 °C Top Ring Reversal (TRR), 175 °C sump temperatures, and friction coefficient of 0.085–0.10 have been met. We have used the test data generated from the laboratory tribology t

Abstract:
A Mobile Emissions Lab (MEL) and two site visits for extensive low load emissions mapping were used to document the emissions performance of the test unit over a 10 month period from June 2015 to April 2016. Data was collected over a wide ambient temperature range from 35 to 108?F. The field trial has demonstrated that the new algorithm results in a significant reduction in NOx, CO and UHC emissions from idle to 50% load. Reductions in CO and UHC emission of 50 to 99% were demonstrated from idle to 50% load. NOx emissions reductions were slightly less ranging from 20 to 75% from idle to 50% lo

Abstract:
An executed NDA is required from Solar Turbines to have access to this document. The low load control algorithm for Solar Turbines' TaurusTM 60-7802S has been modified and evaluated in a field trial at the TransCanada Glenville Compressor Station. The algorithm has been modified to extend the bleed valve operating range to lower engine speed settings covering operation from idle to 50% load. The pilot fuel schedule has also been optimized with the new bleed valve schedule. The new control algorithm is designated as Enhanced Emissions Control (EEC).
