I am trying to implement interfacial component transfer between liquid water and air.

I have a 50m high cylinder with a radius of 15m, where the bottom and side walls are modelled as no slip walls. The top is modelled as an opening with a 0atm relative pressure and a temperature of 298K.
I have succesfully been able to create two homogeneous phases with a clear free surface at the interface by simply creating two fluid types in the domain.

Buoyancy and thermal heat transfer is included, but I further wish to couple the two phases to allow water to evaporate into the air after placing an point energy souce by the surface. How can I go about coupling the phases?
Thanks
