采用CLSVOF方法对球形水滴以一定角度撞击水面时的聚结和飞溅过程进行了数值模拟。撞击角是一次液滴的速度矢量与水面的法向矢量之间的夹角。研究了撞击角、撞击速度、靶液高度等因素对撞击效果的影响。撞击角从0°到90°变化，显示出现象的渐变。可以看到船体形状、液片、二次液滴和火山口的形成。计算了弹坑高度、弹坑位移、拱顶高度和拱顶角度，并记录了这些参数随撞击角的变化情况。
Numerical simulations using CLSVOF (coupled level set and volume of fluid) method are performed to investigate the coalescence and splashing regimes when a spherical water drop hits on the water surface with an impingement angle. Impingement angle is the angle between the velocity vector of primary drop and the normal vector to water surface. The effect of impingement angle, impact velocity and the height of target liquid are carried out. The impingement angle is varied from 0 o to 90 o showing the gradual change in phenomena. The formation of ship pro like shape, liquid sheet, secondary drops and crater are seen. Crater height, crater displacement, crown height and crown angle are calculated and the change in the parameters with change in impingement angle is noted.
