摘要
以一维平底溃坝问题为例,讨论了有限体积法的应用。从溃坝基本方程入手,采用R oe方法计算界面数值通量,采用空间一阶、时间二阶格式(预测校正二步格式)计算溃坝问题,得到了满意的结果。
The paper discusses the application of Finite Volume Method with the sample of one-dimensional flat-bottom dam breaking. The article begins with the basic function of dam breaking,and calculates the numerical flux by means of Roe scheme,the problem is settled under the model of first order in space while second order in time,and the result of the paper is of satisfaction.
