基于热声效应的1／4波长谐振管设计，它使用理想空气作为工作介质，用fluen软件模拟。观察板叠的温度特性和谐振管的流体流动特征，仿真结果表明，入口压力的增加有利于提高热声效应的效率。%The design of 1/4 wavelength resonance tube that is based on the thermo-acoustic effect, uses the ideal air as the working medium,and the Fluent software to simulate.Through observing the temperature characteristics of stack and the fluid characteristics of the resonance tube, the simulation results show that the increase of the inlet pressure is helpful to improve the efficiency of the thermo-acoustic effect.
