| 摘 要： | 采用ＭＡＣ方法求解原始变量不可压缩非定常带自由面问题的Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，对二维水坝瞬间溃决所产生的溃坝水波进行了数值模拟．计算结果表明，在坝溃决的很短时间范围内，液体运动的任一铅直断面上，均不符合静压分布，自由表面的形状类似一抛物线．

| Abstract: | The two dimensional Navier Stokes equations are solved by MAC method to study the waves for dam break impulsively.The mathematical model considered is viscous,incompressible,transient fluid flow problems involving free surface.The results given by the present method show that within a shot time of dam break the pressure distribution on any vertical section is not in agreement with the hydrostatic pressure distribution,and the configuration of free surface takes the form of a parabola. |
