摘要

使用移动粒子半隐式(MPS)法对典型的自由表面流动问题——二维溃坝问题进行了模拟

研究了不同粒子分布对模拟结果的影响

发现对于过大和过小的粒子间距均无法得到合理的结果.将模拟结果与SPH、VOF法结果和实验结果进行了比较

发现MPS的模拟结果介于VOF和SPH的模拟结果之间.在没有引入黏性的情况下

MPS法得到的结果比VOF法的结果更接近于实验结果

预期引入黏性后可达到与SPH法同样合理的结果.

Abstract

The moving particle semi-implicit method(MPS)was used to simulate the typical free surface problem

2D dam break problem

and the effect of initial particle configuration on the simulated results was analyzed. It is found that the reasonable results can not be achieved for too large or too small particle distance. The comparison of the results by MPS

SPH or VOF with the experimental data shows that the result by MPS is between those by VOF and by SPH. Without the consideration of viscosity

the result by MPS is closer to the experiment than that by VOF. However

the result by MPS with the consideration of viscosity may be similar to that by SPH.
