Modeling and simulation of thermoelectric power generation system based on finite element method

The temperature distribution is the crucial part in the design of the thermoelectric power generation system. Based on the temperature distribution, the system efficiency and stability could be effectively improved by using structure design of the thermoelectric power generation system. In this paper, the differential equation model and the finite element governing equation of thermoelectric power generation system is established, the model is analyzed through the finite element method, and the commercial finite element analysis software Ansys is used to simulate the system temperature distribution, with the assistant of APDL (Ansys Parametric Design Language), a parametric model is built and then the temperature field distribution is simulated. The simulation results are not only beneficial to provide guidance for the optimum of thermoelectric power generation system, but also meaningful to evaluate the feasibility of the design scheme of the system.
