| 中文摘要: |
| 本文从Boltzmaun方程出发，采用有限体积KFVS(Kinetic flux-vector splitting)方法，对微观粒子的速度分布进行组合，给出了模拟河道洪水演进时干湿交界处移动边界的一种新方法。并成功地模拟了大坝下游为干河道的一维溃坝模型，通过和精确解的比较得出，此方法在处理河道移动边界问题上是成功和有效的。 |
| 英文摘要: |
| Based on Boltzmann equation a new method of finite volume, namely kinetic flux-vector splitting(KFVS), for simulating the moving boundary in propagation of flood wave in shallow water is proposed. In the method the distribution of particle's velocity are assembled. The method is applied to calculate the 1-D dam break wave. The comparison of the calculation result with that of classical solution shows that the proposed method is effective. |
