| 摘 要： | 采用单相自由面格子Boltzmann方法中流场计算,自由面条件和表面张力处理方法,研究双液滴撞击液膜的流动过程,实现对垂直间隔的两液滴相继撞击液膜流动过程的模拟.数值结果表明,液滴相继冲击液膜时,液滴间上下距离对液膜状态有很大的影响,液滴间距不同,液膜形状会出现很大差异.数值结果与实验结论定性一致.

| Abstract: | With single-phase free surface Boltzmann method for flow field,free-surface condition and surface tension approach,we investigate process of two droplets impacting on a liquid film and two droplets with vertical interval successively impacting on a liquid film.Numerical result indicates that vertical distance between two droplets has influence on liquid film.Shape of liquid film changes greatly with intervals between droplets.Numerical result is in accordance with experiment qualitatively. |
