| 摘 要： | 文章将Level set方法应用于自然空化与通气空化流动计算中,通过耦合入相间的质量传输方程,建立了一个用于描述气、汽、液多相空化流动的数值模拟方法,分别对绕圆头回转体和Clark-Y型水翼的自然空化流动和绕圆盘的通气空化流动进行了数值模拟研究,并与实验结果进行了对比,研究结果表明:相较常用的多相流模型(mixture model),Lev-el set方法通过时间和空间上的压缩离散方案,减小了相间界面的扩散,准确地捕捉到了相间的界面,可以有效地运用于空化多相流动。

| Abstract: | In this study,the Level set method is presented and applied to multiphase cavitating flows.Herein,this method is applied to flow solver that fully couples the mass,momentum,and transport equation;in numerical simulation,the Level set method with a compressive discretization scheme in both time and space to minimize the smearing of the free surface at the interface is used for simulation of nature and ventilated cavity.In these computations,three cases,including the steady nature cavitating flow around the a... |
