英文摘要：

An analysis of the effects of the structural forms of liquid cargo tank on sloshing has been performed. Firstly a mathematical model has been established according to the liquid sloshing features and the structural form of tank. Then the FDM is used to discretize the conservation equations, VOF method is adopted to track the free surface and the conception of aperture is introduced to deal with the obstacles in the fluid field. Finally the effect of the structural form of tank on the sloshing reduction is analyzed.
