Abstract: In recent years, semiconductor thermoelectric generation technology applied on waste heat recovery and recycle of high-temperature exhaust gas has gained wide attention. In this work we construct a testing system to simulate the vehicle exhaust, and study performance of the thermoelectric generator, that recovers the waste heat from automobile exhaust gas and converts it into electricity, by enhancing the heat transfer using foam metals with different hole densities filled in the core flow area.

Key words: thermoelectric power generation, foam metal, heat transfer enhancement, core flow
