Abstract

In this simulation tool, a thermoelectric power generator is optimized together with the heat source and heat sinks for maximum power output and system cost. Full electrical and thermal co-optimization is performed with given material properties, and dimensions to find the optimal thickness of the thermoelectric elements.

One can choose a material property such as Seebeck coefficient and thermal conductivity as an independent variable to optimize the performance of the power generator as a function of the chosen material property. Heat transfer coefficients of the heat sinks at the hot and cold sides can also be varied as an independent variable. Fractional area coverage by thermoelectric elements called fill factor is another parameter that can be optimized for best performance and cost in this simulation tool.

A particular set of parameters is given as an example in this tool to simulate a thermoelectric topping combined steam turbine system for its performance and cost analysis.
