| 摘要: |
| 在光滑粒子流体动力学(SPH)数值模拟中尝试了一种处理固壁边界的边界力方法，给出了一种新的边界力形式。利用SPH方法及边界力方法对水坝坍塌和涌波进入静止水塘这两个自由表面流动问题作了数值模拟。数值模拟结果表明，在SPH计算中使用本文所给边界力处理固壁是行之有效的。 |

| Abstract: |
| A method of boundary force is used to process rigid boundary condition in smoothed particle hydrodynamics (SPH) simulation, and a new boundary force is given. Both problems of the free surface flows: bursting dam and bore, are simulated by using the SPH method via the boundary force. The numerical results show that the method of boundary force can be successfully used to process the rigid boundary condition. |
| Keywords: smoothed particle hydrodynamics rigid boundary condition the free surface flows. |
