NUMERICAL ANALYSIS TO DESIGN THE FIN-TUBE TYPE HEAT EXCHANGER OF STIRLING ENGINE

핀-튜브 형태의 스털링엔진 고온 열교환기 설계를 위한 수치해석 연구

Numerical analysis is conducted to design the high temperature heat exchanger of Stirling engine by using the commercial CFD solver FLUENT. The fin-tube type of heat exchanger numerical calculation is conducted by changing the shape, number and material of fin shape of working fluid channel, etc in three-dimensional combustion field. Adjusted one-way constant velocity is used as the representative velocity of oscillating flow. The optimum design of heat exchanger considering the heat trasfer capability is suggested by using the calculation results.
