Abstract
The Rayleigh-Benard instability for a clear fluid has its equivalent f or a liquid saturated porous matrix. The phenomenological Darcy moment um law cannot give rise by itself to an instability analogous to that of Benard-Marangoni, but the Brinkman model at least allows it. A crit ical Marangoni number exists leading to cellullar patterns and, for re alistic values of the permeability, it is proportional to the inverse of this last parameter.
