| 摘 要： | 传统的空化初生判据没有考察空泡动力效应的影响和空泡的非等温过程，通过对Rayleigh-Plesset方程的适当无因次化，建立了一种既考虑空泡的动力学效应又适合各种绝热指数的简便的空化初生动力判据。计算了不同环境压力对空化初生的影响。

| Abstract: | The classical criterion for cavitation inception does not accounted for the effect of cavitation bubble dynamics and non isothermal process. By properly non dimensionalizing the Rayleigh Plesset equation, the dynamic criterion of cavitation inception was established, which not only accounts for the dynamic effects of cavitation bubble, but also suits for any value of the polytropic coefficients. The influence of different environmental pressure on the cavitation inception was discussed. |
