采用SIMPLE法结合Van Leer格式开发了铸件三维充型数值模拟计算程序。用单相SIMPLE方程同时求解气液两相流动 ,用Van Leer格式处理自由表面控制方程。用薄壁铸件的反重力充填试验做了验证 ,并对立方体反重力充填进行了计算。
Using SIMPLE method combined with Van Leer format developed three-dimensional casting numerical simulation program. Simultaneous determination of gas-liquid two-phase flow with single-phase SIMPLE equation and free-surface control equation with Van Leer format. The anti-gravity filling test of thin-walled castings was verified, and the cubic anti-gravity filling was calculated.
