摘　　要：基于有限差分法建立液态金属充型过程流动计算的数学模型,使用SOLA-VOF数值模拟技术开发液态金属充型过程三维流动场数值模拟分析软件.然后,利用该软件计算标准实验铸件充型过程的三维流动场,结果与经典算例近似,表明该软件关于流场的计算精度较高.A mathematical model was put forward for simulating the fluid flow phenomena during mold filling of liquid metal using the finite difference method. A computational program was developed based on the SOLA-VOF algorithm for numerically calculating the 3-D fluid field during mold filling of liquid metal. Finally, by using the program, numerical calculation on fluid field during mold filling of benchmark test casting was carried out. The results of numerical simulation are similar to agree well with those of classic examples, which indicates that the program is of high precision in numerical calculation.
