通过对确定自由表面界面流率的Ｖａｎｌｅｅｒ格式进行修正，解决了气液界面的界面模糊问题。在利用ＰＨＯＥＮＩＣＳ流场计算功能的基础上，应用守恒标量法进行型腔充填过程紊流流动的三维数值模拟。针对Ｊ．Ｃａｍｐｂｅｌ的基准实验，用守恒标量法进行充型过程数值模拟的结果与实验结果基本相符。
The Vanleer format for determining the free-surface interface flow rate was corrected to solve the interface ambiguity problem at the gas-liquid interface. Based on the computational functions of PHOENICS flow field, three-dimensional numerical simulation of turbulent flow in cavity filling process is performed by using conservation scalar method. For J. Campbel’s benchmark experiment, the results of the numerical simulation of the filling process by the conservative scalar method are in good agreement with the experimental results.
