The experiment focuses on the temperature of the gas in the hot end heat exchanger, the temperature decline of the cold end of the pulse tube and pressure amplitude.
进行三个脉冲管与行波型热声发动机的配合实验，着重研究了热端气体温度、冷端温降和压力振幅的变化规律。
As a simple device without moving parts, vortex tube is composed of nozzle, vortex chamber, separating plate, control valve, hot-end and cold-end.
由于冷端孔板的阻隔，外层气流便高速螺旋状向热端管运动，流动的涡流特性也同时向热端管运动而逐渐减弱。
