Stability of Convective Flow in a Porous Medium
Deeanne Westbrook · The Physics of Fluids · 1969
A universal criterion for the stability under arbitrary disturbances of the convective flow of a fluid in a porous medium is obtained in terms of a Reynolds number and a Rayleigh number for the flow. It is also shown that stability bounds obtained by small perturbation methods are equally good bounds under arbitrary disturbances.
