Slip velocity in evaporation-condensation model

xuansy · October 7, 2018, 05:18

Hello,
I am using the evaporation-condensation model with mixture multiphase model to solve water-liquid-vapor flow. At the initial time, the volume fraction of liquid phase is 1, and the liquid evaporate to vapor when a heat flux is given to a wall.
But the velocity of liquid and vapor is the same, so the vapor will gather in the fluid zone. So if I want the vapor have a large velocity, how do I set in the Fluent.
Can anyone help me with this problem? Thanks very much.
Best Regard, Shiyao Xuan
