Influence of Geometric Parameters on Power Generation from a Thermoelectric Module

Exploring and studying alternative energy options are essential for solving the energy crisis. A thermoelectric (TE) generator is one of the best options available for waste heat recovery. To enhance the performance of the thermoelectric device, it is essential to study the thermoelectric module and analyze the factor affecting the performance of the TE module. In the present work, the influential parameters such as leg length, leg width, load resistance, and temperature on the hot side of the TE module with different combination are numerically investigated. The current numerical work provides the optimal value of the each parameter for efficient working of the TE generator. A 3D model of thermoelectric unicouple is developed to analyze the effect of aforementioned geometric parameters. Moreover, the results of leg length, leg width, load resistance, and temperature on the hot side of the device on the efficiency and power output with constant surface temperature boundary condition are discussed.
