摘　　要：该文应用Level Set方法研究了二维溃坝问题.用二阶投影法和高阶迎风格式求解二维Navier-Stokes方程,用CIP(cubic-Interpolated Pseudoparticle)方法求解Level-Set方程.通过数值计算得到了各个时刻溃坝运动界面的变化和相应速度的分布,该文的数值结果与相关的数值实验结果基本一致,说明该文的算法对于捕捉溃坝波的破碎和融合是实用且有效的.In this paper, the level set method is introduced to simulate the flow of dam-break. The second order project method and high order upwind difference scheme are used to solve the two-dimensional Navier-Stokes equations, and CIP(cubic-interpolated pseudo-particle) method is adopted to solve the Level Set equation. The simulation results focused on the evolution of the moving interface and the contour of the velocity of the dam-break at different moment. The numerical results are shown to be in good agreement...
