摘要
利用瞬态流理论和水声学原理分析了风琴管自振空化射流喷嘴的工作原理,推导了风琴管谐振腔的固有频率计算公式,得出了谐振腔基本结构的设计模式.研究表明,风琴管自振空化喷嘴的设计需运用理论和实验的方法进行.风琴管谐振腔的直径和长度是影响谐振腔流体共振的重要因素,需通过试验确定.
In this paper the mechanism of self-excited organ-pipe cavitating jet nozzles is analyzed in light of the theories of fluid transients and a coustics. The formulas determining the natural frequency of an organ-pipe resonator are derived. The basic dimensional model of an organ-pipe resonator in peak oscillation are also given. The principle of the design of self-resonating cavitating jet nozzles is discussed. The diameter and length of the organ-pipe resonator are the important factors affecting the flow oscillation, and should be determined by test.
