Abstract In the corrugated plate separator, the droplets are separated by impacting on the wall of the corrugated plate, so it is necessary to study the droplet impacting on liquid film. In this paper, CLSVOF method is used to analyze the liquid droplets impacting on different thicknesses liquid film. The morphology of crown, the velocity field and pressure field distribution inside the liquid film have been studied, and the morphology, velocity field and pressure field of successive droplets impacting on liquid film are analyzed. The conclusions are following: With the increase of liquid film thickness, the radius of crown increases but the height of crown decreases. Liquid film thickness and distance from the free surface of the liquid film are influence on velocity and pressure in liquid film; when successive droplets impact on liquid film, with the increase of time interval of two droplets, the second splashing occurs more easily.

CLSVOF分析液滴对液膜的影响

摘要 在波纹板分离器中，液滴通过撞击波纹板壁而被分离，因此有必要研究液滴撞击液膜。本文采用 CLSVOF 方法分析液滴对不同厚度液膜的影响。研究了液膜内部的冠部形态、速度场和压力场分布，分析了连续液滴撞击液膜的形态、速度场和压力场。结论如下：随着液膜厚度的增加，冠部半径增大，冠部高度减小。液膜厚度和距液膜自由表面的距离对液膜中的速度和压力有影响；当连续液滴撞击液膜时，
