Abstract
In this research, our interest focused on the thermo-acoustic prime mover to recover the waste heat and effective utilization of it. The advantage of this prime mover are the flexibility for various heat source as an external engine and has a possibility as the cost effective system due to simple structure. To improve the total thermal efficiency, various efforts have been made experimentally and theoretically. In this research, experimental attempts are made to grasp the optimization of stack structure which plays an important role to energy conversion. Finally, discussion on the future application of prime mover aiming to utilize the waste energy of exhaust gas is made.
