Enhancing Thermoelectric Generator Performance, Xi William Wang
Electronic Theses and Dissertations
Waste heat recovery plays an important role for alleviating the energy crisis and mitigating climate change. The thermoelectrical generator (TEG), a solid energy convertor, is a promising technology. However, the performance of a TEG is sensitive to its geometric structure and working conditions. An improved geometric structure and matching to the working conditions can make a TEG fully utilize its thermoelectrical conversion potential.
The TEG optimization is a kind of combinatorial problem. An effective algorithm is needed to optimize a TEG’s performance. The particle swarm optimization (PSO) algorithm is introduced in this study to optimize a TEG’s output power, efficiency, …

Transient Experimental Study Of A Latent Heat Thermal Energy Storage In A Phase Change Material-Air-Liquid Heat Exchanger, Serena Askar
Electronic Theses and Dissertations
The increase in energy consumption and the demand for effective thermal management systems necessitate the search for enhanced heat exchangers with high thermal performance, lower weight, and compact sizes. Crossflow heat exchangers are a key component in the thermal management system of many industries such as HVAC, automotive, etc. Generally, heat exchangers are characterized based on their steady state operating conditions. However, a transient analysis helps predict the behavior of heat exchangers when they experience variations in their operational conditions in terms of fluid flow rate and temperature.
Thermal management and thermal comfort can be achieved through active and passive …
Predictive Model Of Air Dam Deflection Under Aerodynamic Loads, Chang Kyun Kang
Predictive Model Of Air Dam Deflection Under Aerodynamic Loads, Chang Kyun Kang
Electronic Theses and Dissertations
Plastic components are widely used on the exterior body of automotive vehicles. When the vehicle is moving, these components experience deformation caused by air flow. Simultaneously, the deformation affects the flow of air around the vehicle. This research is focused on developing virtual simulation techniques for determining the vehicle air dam behaviour under aerodynamic loads. The main objective of this research is to develop a fluid-structure interaction (FSI) methodology for predicting deflection of the air dam.
Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) codes are coupled so that fluid pressure and air dam displacement parameters are exchanged. The …
