Ushu is on a distinguished road

This is my first post on this forum, and I am newbie to openFoam. I need to apply a boundary condition such that the normal velocity to a patch is determined by relating the vaporization rate to the conductive heat flux at the surface. The equation loos like this:

ro*v*L = mu*(dh/dy)


ro = density
v = y velocity
L = latent heat of vaporization
mu = viscosity
h = sensible enthalpy

I have read that there may be a predefined boundary condition that suits my needs, but I haven't been able to find it. Also, I have tried to use swak4Foam but I can't just follow the instructions found in the web page (I have started using CAElinux and openFoam 2 days ago).

If someone could help me it would be really appreciated.
