摘要
移动边界问题是水力计算中难点之一 ,本文用拉格朗日坐标系来描述浅水方程 ,并用二阶Godunov算法求解有移动边界的浅水问题的数值解。在拉格朗日坐标系下 ,移动边界条件十分容易处理 ,数值计算结果表明 。
Moving boundary problem is one of the difficulties in hydraulic computations. In this paper the shallow water equations in the Lagrangian coordinates were derived and the numerical solutions were found out for shallow water problem with moving boundary by using a 2 order Godunov scheme. The numerical example shows that this method is powerful and efficient in solving shallow water problems with moving boundary.
