为研究空化喷嘴产生的空泡射流在不同深度环境下的影响因素,该文采用理论分析和数值模拟相结合的方法,研究了不同环境下空泡的差异,并总结空泡内气相体积分数和速度的变化规律,可得到其他条件相同时喷嘴入口压力越大产生空泡体积越大,水下深度越大空泡长度越小的结论。 In order to study the influencing factors of cavitating jets generated by cavitation nozzles under different depth conditions, this paper uses theoretical analysis and numerical simulation methods to study the differences of cavitations in different environments, And the speed of the law of change can be obtained when the other conditions are the same nozzle inlet pressure is greater the greater the volume of the bubble, the greater the depth of the underwater bubble smaller the length of the conclusion.
