摘要(Abstract):

对收缩—扩散型出口空化喷嘴的出口段泡液流稳态解的分析表明 :泡液流中很小的空隙率亦强烈地影响着其流动特性。试验证明具有收缩—扩散形出口流道的空化喷嘴的空化效果更好。
Using the nonlinear bubble dynamic equation coupled with the bubbly liquid flow equations, the steady-state solutions for cavitating flows through a converging-diverging nozzle exit are analyzed. It is shown that the flow properties are affected dramatically even through the void fraction in cavitating flow is very small. Cavitation of the cavitating nozzle with converging-diverging exit is stronger.
