| 中文摘要: |
| 采用移动粒子半隐式法(MPS)模拟了受表面张力影响的自由面流动。表面张力的计算采取了一种较适合于MPS方法的表面自由能模型。方形液滴振荡和射流断裂的模拟结果分别与理论分析和试验结果一致,同时进行了三维射流注水模拟,从而验证了MPS方法结合该表面张力模型可以有效、方便地进行自由面流动中表面张力现象的模拟。 |
| 英文摘要: |
| This study used the moving particle semi-implicit (MPS) method to simulate the surface tension force in the free surface flow. A surface tension force model for the MPS was implemented, which was proposed based on the potential energy. This numerical approach for the surface tension force in the free surface flow was verified by the numerical simulation of the two-dimensional liquid droplet oscillation and the liquid jet breakup. Simulation results agreed well with analytical or experimental ones. Moreover, a three-dimensional water jet into a cylinder was simulated using the MPS method together with the surface tension model. It was then validated that the MPS method together with the surface tension model can effectively and easily simulate the surface tension force in the free surface flows. |
