冲击式旋转机械中气蚀穴泡的动力学特性(英文)

Dynamic of Cavitational Bubbles in Rotor Impulse Apparatus

建立了描述冲击式旋转机械中穴泡群特性的数学模型。该模型的牲征为：认为火泡是旋转机械中液体的压力脉动引起的。最后，给出了相对穴泡产生压力与斯特罗准数（Ｓｔｒｏｕｈａｔ）的关系曲线。

The mathematical model of cavitation cluster in the rotor impulse apparatus is developed. The feature of this model is that cavitation is generated by the anharmonic pressure pulse generated by rotor impulse apparatus. The dependence diagrams of relative generated cavitation pressure on Strouhal criterion are given.
