porous medium + Rayleigh number

How does one calculate Rayleigh number for natural convection in porous medium?

Hello!

I have to solve a model with porous zone. It's my first model with porous zone. I can't determine boundary conditions for this solve. My model has three volums: Volume 1 - gas volume (fluid) Volume 2 - porous volume (porous) Volume 3 - gas volume (fluid)

I don't know as I can realize boundary conditions on boundary surfaces between gas volume and porous volume. There are two concurring surfaces between gas and porous volumes. Whats boundary conditions I must realize on this surfaces? Sorry for my bad English. Thank you for the answer. Andrew.
