摘要: 为了适应数值模拟浅水涌波的需要,给出了冻结直角坐标系下的浅水波方程组系数矩阵的Roe平均法。通过对一维浅水波方程组的几种冻结法关于溃坝问题进行的数值实验比较,充分展示了Roe平均法在模拟涌波方面的优越性

Abstract: For the need of numerical simulating the shallow-water bore, the Roe average method about the coefficient matrix of shallow-water wave equations is presented. Several freezing methods are used to treat the one dimensional shallow water wave equation for numerical examining with a dam breaking problem, numerical results show the superiority of the Roe average method in simulating the bore.

Key words: shallow-water bore, Roe average method, numerical simulating
