A two dimensional simulation is carried on to simulate the droplet evolution after impacting on liquid film by CLSVOF (combined level set and VOF). At different parameters the droplet evolutions are obtained and the phenomenon of bubble entrainment is caught successfully. The effects of impact velocity and the liquid film thickness on the crown diameter are analyzed. The results indicate that the bubble entrainment can be captured by CLSVOF method. Also it can be concluded that the bigger the impact velocity is, the earlier the splash emerges. The spreading diameter decreases with the rise of liquid film thickness. (c) 2014 Elsevier Ltd.
