| 摘 要： | 本文提出了环形三部分对称结构的气液双作用行波热声发动机,该发动机采用U形谐振管并引入液体活塞。本文针对平均工作压力、加热器加热量以及液体活塞质量等不同运行参数对系统性能的影响进行了数值模拟。模拟结果表明,提高平均工作压力、增大加热器加热量有利于提升系统压力振幅;引入液体活塞1.13 kg时,系统谐振频率达到最小值17.48 Hz。

| Abstract: | A double-acting traveling-wave thermoacoustic engine involving in a U-shaped resonant tube was designed and simulated,analyzing the influence of mean working pressure,heating input and the water column mass on the performance of the engine.According to the simulation,higher mean working pressure and more heating input are desired,which is helpful to increase the pressure amplitude.Besides,the resonant frequency achieves minimum of 17.48 Hz when the water column mass is 1.13 kg. |
