在ＰＨＯＥＮＩＣＳ软件的基础上开发了充填过程模拟软件，可用ｖａｎＬｅｅｒ格式求解守衡标量方程而获得充填过程中的自由表面．用层流假设、标准的Ｋε紊流模型和代数应力模型分别对充填过程进行数值模拟，研究了不同流动模型对充填过程模拟结果的影响．结果表明：层流假设、Ｋε紊流模型和代数应力模型对充填过程都有其适用的范围，可对不同的情况选择其一． Based on the PHOENICS software, a filling process simulation software has been developed that uses the van Leer format to solve the conservation scalar equation to obtain a free surface during filling. The laminar flow hypothesis, standard Kε turbulence model and algebraic stress model were used to simulate the filling process respectively, and the effects of different flow models on the filling process simulation results were studied. The results show that the laminar flow hypothesis, the Kε turbulence model and the algebraic stress model have their applicable scopes for the filling process, and one can choose one for different situations.
