I want to model the surface of water heated in a container. For this I need to take the water-air interface into account. Please suggest any two phase model method.

Thanks

I have to model the free surface of water in a square cavity whose left and right walls are maintained at fixed temperatures , bottom wall is insulated and the top surface is exposed to atmosphere. Basically I have to ensure that the surface generated is such that the pressure is constant over it. Can you also explain the procedure to use the correct model?

Thanks in advance

Sumeet

The whole problem is under steady and lamionar assumption and I am using Boussinesq model for convection. If you have a better method then pls suggest

Thanks Sumeet
