چکیده
This paper investigates the design of a thermoelectric generator for exhaust gases from internal combustion engines. Experimentally validated CFD methodology was employed. Different issues are studied, such as influence replacement pipe TEG, recirculation produced, and fins. The results show that an enlarged inlet cone reduces pressure drop but more heat is lost across walls, reducing available modules. Internal straight fins aligned with flow achieved 3% increase in transfer, did not significantly this type device, reduced effects on recirculation, lowering overall by 10%. An energy production 175.9 W 16.2 power losses resulted net 160.7 W. A comparison flat-type under same hot source conditions also provided.
