Simulation of a novel hot-side heat exchanger for automobile exhaust based thermoelectric generators using EFDlab

A computer simulation to predict the thermal performance of a novel hot-side heat exchanger for exhaust-based thermoelectric generators (ETEGs) has been developed. This simulation investigates the novel design features of the heat exchanger that can be represented in the implementation of copper-bas...
