摘要/Abstract

摘要： 采用离散速度模型计算二维溃坝波问题. 按照浅水波方程与气体动力学方程的比拟关系, 给出用于计算浅水波方程的离散速度方法. 计算了两个二维溃坝波问题：圆形溃坝波问题和部分水坝倒塌后的水流问题. 计算结果显示, 此模型计算程序比较简单、有效, 且稳定.

Abstract: The numerical solution of the two dimensional dam break waves is described by a discrete-velocity model. Based on the analogy to gas d ynamic equation the discrete-velocity model can also be used to stimulate the shallow water wave equations. Two numerical calulations including a 2-dimensional circular dam break wave and a partial dam break wave were carried out. The numerical results show that the model is easy to implement, effective and stable.

Key words: dam break wave, shallow water wave equation, discrete-velocity model
