Hi,
I am trying to figure out why Fluent shows increase in phase-2 volume fraction in a closed domain (no inlets and outlets) and steady runs. Isn't this against the basics of control volume formulation!! I have always learned that mass conservation is a key property of this formulation!! |

Vof solves the:
1. Momentum equations based on mixture properties. 2. Volume fraction transport equation. What about the continuity equation?? |
