| 摘 要： | 在水流体运动问题的三维数值模拟中,结合拉格朗日法和欧拉法的物质点法具有计算精度和计算效率比较高的优势,本文应用物质点法和显示积分算法对水柱在固壁面上自由塌落、箱体内水流溃坝和水流绕过障碍流动的过程进行三维数值仿真,从数值仿真结果看,与实际水流的运动过程较为符合,表明物质点法在模拟水流体运动问题同样是一种有效的仿真方法。

| Abstract: | To 3D simulation of fluid dynamics problem, Material point method is a kind of effective powerful algorithm which takes advantage of both Eurlerian and Lagrangian methods. In this paper, material point method is applied to simulate water collapsing on the solid surface, breaking down in box and flowing around columns with explicit integration. The results are coincident with actual flowing status of water. It is proved that material point method is a robust tool in solving of fluid dynamics problems. |
