Enhancement in performance of heat transfer is one of the most significant issues for a heat exchanger in exhaust heat recovery systems. In design of the heat exchanger, increase of heat transfer area and enhancement of heat transfer are generally considered. On the other hand, a practically-designed heat exchanger cannot provide enough performance in terms of heat transfer due to restrictions of installation space of the system and pressure drop of working fluid. In this study, the optimum design of a heat exchanger has been considered for the solution of a trade-off problem between heat transfer rate and pressure drop of exhaust gas based on genetic algorithm coupled with the mathematical model for performance analysis of the heat exchanger. This paper also has presented a validation study of the mathematical model with the experimental benchmark. And then, the optimum design method for the exhaust gas heat exchanger has been mentioned.
