The optimization of heat transfer area in the regenerator is performed using the concept of enthalpy flow, which is commonly used in thermo-acoustic devices. When the hydraulic diameter is large i.e. heat transfer is low in the regenerator, enthalpy flow from the heat source to the heat sink is not negligible and it requires more heat exchange in the heater and the cooler. This enthalpy flow approaches zero but flow loss increases, as hydraulic diameter becomes small. We propose the optimum condition to be the enthalpy flow at the end of the regenerator 40% of indicated work. Cooperating with the maximization of output power and highest thermal efficiency, the optimization of not only hydraulic diameter but also cross sectional area of the regenerator was performed.
