| 摘要: |
| 基于Rayleigh-Plesset方程,在考虑空泡界面上的相变作用后,导出了一个新的空化模型,并利用此模型模拟了次生空泡的发育与溃灭．新空化模型应用于半球头航行体的结果表明:由于次生空泡不断溃灭与发育,模型表面压力由较高的溃灭压力和较低的空泡压力交替分布;随着空化数的降低,主空泡逐渐变大,次生空泡区逐渐向模型尾部移动并脱落． |

| Abstract: |
| Considering the effects of phase-change on the bubble interface, a new cavitation model based on Rayleigh-Plesset Equation is given and the secondary cavitation is successfully modeled. Using the new cavitation model on cavitation flow fields of the 2 d steady axisymmetrical hemispherical cylinder, the model surface is alternately distributed by a higher cavity pressure and lower collapse pressure due to the growth and collapse of the secondary cavity. With the decrease of cavitation number, the main cavity gradually becomes larger, and the secondary cavity zone is gradually moving to the tail of the model and falling off. |
