Equilibrium and non-equilibrium thermal models are studied using the method of volume averaging in the neighborhood of the boundary that separates a porous medium and a fluid.
The spatial variations of several effective transport coefficients from one medium to the other were numerically computed.
Particle-particle contact plays an important role specially when physical properties of phases are clearly different.
