Abstract

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.

Key words: lattice Boltzmann method, free surface, two-phase fluid flows, liquid droplet
