“…Therefore, thermoelectric generation is expected to provide a way to enhance the performance of IC engine-based vehicles by recovering waste heat into electricity. Heo et al experimentally and numerically studied the heat transfer behavior of various inside shape components of plate-type heat exchanger and showed that brass as construction material could provide enhanced effectiveness for thermoelectric power generation using wasted heat [3]. Various geometrical parameters including dimensions of thermoelectric generator, number of thermoelectric modules, fin parameters of heat exchanger, thickness of heat exchanger play important role in designing the heat exchangers [4][5].…”

Background/Objectives: The parametric study on heat transfer characteristics of waste heat recovery heat exchanger was carried out by varying different geometry parameters to suggest optimum model for automotive exhaust thermoelectric generator.Methods/Statistical analysis: The numerical analysis method was applied to compare the heat transfer characteristics of various heat exchanger models. For numerical analysis, various models were created using computer aided drawing considering different fin arrangements and guide plates. Commercial code ANSYS 17.0 was used to analyze the heat transfer and fluid flow behavior of various models. Mesh independency was conducted to enhance the accuracy of the results.Findings: The thermal performance analysis of waste heat recovery heat exchanger was conducted considering pressure drop and heat flux at cooling side. As the fin spaces were increased, the heat flux at cooling side increased, but pressure drop also increased.Improvements/Applications: The developed geometry can be further optimized considering other geometry parameters and efficient system could be developed for power generation using waste heat with heat recovery exchanger and the present study provides detailed numerical analysis considering pressure drop and heat flux.
