摘要
设计一种高效率的热声制冷机谐振管,采用Fluent流体软件对比渐扩管、直管、渐缩管中的压力,发现渐缩管具有增压作用。设计了1/4波长的谐振管,并调节其声腔使其达到纵向谐振频率状态,以便提高热声制冷机的效率。
In order to improve a high efficiency of the thermoacoustic refrigerator resonance tube, comparing the diffuser pipe, straight pipe, reducing pipe pressure in the fluid with Fluent software, and find that reducing pipe having a turbocharged effect. The resonant wavelength of 1/4 pipe is designed, and the cavity is adjusted to achieve the longitudinal resonant fre- quency for improving the efficiency of the thermoacoustic refrigerator.
