中文摘要：

格子 Boltzmann 方法(LBM ) 被调查在水力的动力学解决 triangularcavity 流动和免费表面的问题。三角形的洞 flowand 的一些案例向后走流动被模仿显示出透露水坝裂缝 wavearound 的问题和繁殖和衍射的这个 method.Two 维的部分水坝的效率和稳定性矩形、圆形的柱体数字地成功地被学习。在数字预言和可得到的结果之间获得的优秀 agreementwas。

英文摘要：

The Lattice Boltzmann Method （LBM） was investigated to solve triangular cavity flow and free-surface problems in hydraulic dynamics. Some cases of triangular cavity flow and backward step flow were simulated to show the efficiency and stability of this method. Two-dimensional partial dam breaking problem and the propagation and diffraction of dam-break wave around rectangular and circular cylinder were numerically studied successfully. Excellent agreement was obtained between numerical predictions and available results.
