| Abstract: | According to the physical regulations of fluid flow of metal liquid, govern equations of mold filling in metal casting are described and mathematics model is built. The finite difference forms of govern equations are derived which meet the demands of accuracy and calculation stability. These finite difference forms of govern equations can conduct fluid flow analysis. |
