Fluid Resistance

The HE (heat exchanger) of automotive exhaust TEG (thermoelectric generator) plays a vital role in converting thermal energy into electrical energy, therefore achieves the goal of energy conservation and emission reduction. A new regular-octagon HE is modeled and simulated in FLUENT to obtain the velocity path-lines of fluid. Through simulation results, the velocity path-line is tracked and analyzed, in order to evaluate the fluid resistance and fluid turbulence intensity. By using control variable method, a variety of HE models with different structural parameters are modeled and simulated, to optimize the structure of HE. Eventually, it is intended to design a HE with proper fluid resistance and remarkable turbulence intensity.

New System

A new system for converting combustion heat into electric power was proposed on the basis of countercurrent burner with thermoelectric element embedded in a wall separating incoming fresh mixture and combustion products. The wall serves as heat exchanger between combustion products and the fresh mixture. Numerical simulations showed that almost whole combustion heat may be transferred through the thermoelectric element in such system and the total thermal efficiency attained a value close to the conversion efficiency of the thermoelectric device itself.
