Experimental Study on a Thermoacoustic Engine with Brass Screen Stack Matrix
A thermoacoustic engine is a new type of pressure wave generator. With no moving parts, it is a simple, reliable, and long-term nonmaintenance machine. It has great potential in space application. An experimental thermoacoustic engine has been fabricated recently. A maximum pressure ratio of 1.12 has been obtained using a working fluid of nitrogen and 1.06 with helium, with corresponding frequencies of 25 Hz and 70 Hz, respectively. The influence of operating conditions and structural parameters on the performance of the engine was also tested.
