Abstract

The porous medium can gain a relatively large temperature difference in vent-pipe. In our thermoelectric porous medium system, temperature difference was utilized to produce electricity to utilize exhaust energy. It is supposed that temperature of gas and temperature of solid were the same in the thermoelectric porous medium, the three-dimensional mathematical model by rotational flow was established in the vent-pipe. Using finite volume/SIMPLE method, the flow field and the temperature field was obtained numerical. The simulating results show that the region of larger temperature gradient was available to install the thermoelectric device.
