partially filled tank, evaporation at liq-vap.

prasanth

1. I am simulating a closed tank(cylindrical) in which liquid cryogen is partially filled.when heat flux is applied on the walls, natural convection occurs and evaporation takes place at the interface. For this problem, what model is suitable in multiphase models. i think any one we have to use UDF.

2. how to calculate amount of each phase in a zone, in axisymmetric model. i.e. each amount of vapor and liquid in post processing. i tried with define custom-functions and reporting it in surfacce integrals. it showed different value for 3d and axisymmetric model. i used 'density-liq*VOF-liq*cell-volume'for custom function.

I will appreciate ur help. Prasanth
