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 tubeand 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 andcold-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。

The use of hot water andcold water sinking tube floating principle, causes the water to produce the microcirculation and water to reach the needed.
