英文摘要：

Liquid sloshing phenomenon of flow field with obstacles is simulated based on the level-set method coupled with the conception of aperture in this paper. First, the technique used in this paper is validated by comparing the experimental result with the result of numerical simulation. Then, different structures are added to the liquid tank and the effects of restraining sloshing are compared. Some important conclusions are made in this paper. The results show that the technique of combining the level-set method and the aperture-coefficient method can effectively deal with the liquid sloshing problem in flow field with obstacles.
