Summary

THE EFFECT OF NON-HOMOGENEITY OF THE MEDIUM IS INVESTIGATED IN THE CASE OF NATURAL CONVECTION IN A VERTICAL THE FLOWS ARE DRIVEN BY CONDITIONS OF UNIFORM HEAT AND MASS FLUXES IMPOSED ALONG THE 2 VERTICAL SIDE WALLS OF THE POROUS LAYER. IT IS FOUND THAT THE EFFECT OF NON-HOMOGENEITY IS SIGNIFICANT FOR SHARPER PERMEABILITY VARIATIONS AND LARGE RAYLEIGH NUMBERS, LEWIS NUMBERS AND ABSOLUTE BUOYANCY RATIOS. NUSSELT AND SHERWOOD NUMBER ESTIMATES IN SUCH CASES ARE FOUND TO BE QUITE DIFFERENT FROM THAT OF THE HOMOGENEOUS MEDIUM.
