Dynamics of Single Droplet Splashing on Liquid Film by Coupling FVM with VOF

A three-dimensional numerical study of a single droplet splashing vertically on liquid film is presented. The method based the finite volume (FVM) Navier–Stokes equations coupled with fluid (VOF) method, and adaptive local mesh refinement technology adopted. It enables liquid–gas interface to be tracked more accurately, less computationally expensive. relationship between diameter free rim, height crown different numbers collision Weber, thickness explored. results indicate that increases as Weber number increases, rim inversely proportional number. can also concluded dimensionless decreases increase in film, which has little effect during its growth.
