Analytical Performance Evaluation Of Thermoelectric Modules Using Effective Material Properties, Sean Lwe Leslie Weera
Analytical Performance Evaluation Of Thermoelectric Modules Using Effective Material Properties, Sean Lwe Leslie Weera
Masters Theses
Designers often face the predicament of non-standardized forms of performance data provided by thermoelectric module manufacturers. Other than experimental means the only method to evaluate the performance of a product would be through analytical modeling using material properties that are usually undisclosed and unknown. This work studies the theoretical approach of obtaining such material properties using the maximum operating parameters reported by the manufacturers. These values are then analytically employed to evaluate the performances of these thermoelectric modules. Experimental means are also devised and carried out on these test samples to validate the integrity of the results. Three-way comparisons between …
Benchmarking Of A Single-Cylinder Engine Toward The Development Of A Direct Fuel-Injection System, Michael J. Nienhuis
Benchmarking Of A Single-Cylinder Engine Toward The Development Of A Direct Fuel-Injection System, Michael J. Nienhuis
Masters Theses
In this study, the performance and efficiency of a single-cylinder gasoline, fourstroke cycle engine was benchmarked in support of the Formula SAE student project. The development of an engine test stand, instrumentation, data acquisition, and test plan is described in detail. Experimental results in the areas of engine performance and efficiency are discussed. Physical test data were used to refine a previous model of a single-cylinder, gasoline, direct-injection engine. Results from this effort are discussed and compared to those obtained in a preliminary study. The current work advances the development of more efficient power-train technologies for application in small displacement …
