two-pahse wave model

Hi gays!
I am trying to build a numerical wave tank based on air-water two-phase model.I am new in this area,and here is my quations:

1.The density changed in the free surface.If I use the old time density,and didn't consider time change of density,does that mean the free suface won't move.

2.Can I think in that way if the density of air above water treated as const,then air volume come in and out the surface cell are equal to the volume of water change in this cell,so the density can treated as const.

3.Does anybody have some suggestion about this problem.

gays,

I think I made a mistake it is difficult to renew the density of the interface with coupled methods.

Thinks!
