 September 29, 2009, 12:07 governing equations for liquid mixing with free surface? #1 Senior Member   Pei-Ying Hsieh Join Date: Mar 2009 Posts: 271 Rep Power: 9 Dear CFD experts, I would like to model mixing of two liquids with free surface, ie, two liquids + air. The free surface will be modeled by VOF. I know how to derive single liquid + air using VOF, but, how to derive the governing equation with two liquids (two VOF?) mixing with air presents? Is there any literatures in this area? It will be appreciated if someone can shed some light on this. Pei

Here you go

Simulation of Multiphase Flows in Complex Geometry Using a Hybrid Method Combining the Multi-Fluid and the Volume-of-Fluid (VOF) Approaches, Alajbegovic, A., Han. J., FEDSM2002-31153, Montreal, Quebec, 2002.

hope this helps

HI, Figd84, I have liquid A inside a cup, then, a liquid jet (liquid B) shoot into the cup. I am interested in mixing of the two liquids. I am not quite sure how to derive the governing equations.
