Coalescence Collision of Two Droplets:Bubble Entrapment and the Effects of Important Parameters

In this study, coalescence collision of two water droplets is studied using a modified Volume of Fluid (VOF) method. The focus of this work is on head-on binary collision of two droplets; the effects of Reynolds number, drop size ratio and impact velocity on the coalescence process are investigated. In addition, air bubble entrapment phenomenon during droplet collision is discussed.
