摘要 针对溃坝流动自由表面大变形问题,基于粒子法的优点,应用移动粒子半隐式(MPS)方法进行流动模拟.通过两个溃坝算例,数值模拟并与试验对比了自由表面大变形现象.结果表明:选取较小粒子直径的MPS方法对自由表面大变形问题模拟效果较好. Considering its advantage of particle discretization, the moving particle semi-implicit method is ap- plied to the numerical simulation of dam-break flow with highly distorted free surface. Two cases of dam-break are simulated and compared with experiments on phenomenon of highly distorted free surface. The results show that MPS method with small particle diameter is advantageous for simulation of the highly distorted free surface flow.
