中文摘要：
应用CLSVOF数值方法模拟并计算液箱剧烈晃荡的砰击载荷。该方法由level-set方程获得网格内自由液面法向量，并由PLICVOF方法重构自由液面，然后在重构后的自由液面上进行level—set方程的重新初始化。应用该方法，模拟了横摇以及横荡共振激励作用下低装载液箱的晃荡砰击载荷，并与实验结果进行了对比，计算结果与实验结果较为一致。
英文摘要：
A coupled level-set and volume-of-fluid （CLSVOF） method is adopted to simulate violent sloshing motions with impact load in tanks. For this method, the interface is reconstructed by a PLIC VOF （Piecewise linear interface calculation and volume-of-fluid） scheme with normal vector obtained from LS function. The level-set function is re-distanced based on the reconstructed interface. With the application of CLSVOF method, two violent sloshing flows in tanks excited by resonant roll motion and resonant sway motion under shallow water depth are simulated and validated with experimental re- suits, and good agreements are observed.
