Summary

THIS PAPER REPORTS A FUNDAMENTAL STUDY OF THE PHENOMENON OF NATURAL CONVECTION HEAT AND MASS TRANSFER NEAR A VERTICAL SURFACE EMBEDDED IN A FLUID-SATURATED POROUS MEDIUM. THE BUOYANCY EFFECT IS DUE TO THE VARIATION OF TEMPERATURE AND CONCENTRATION ACROSS THE BOUNDARY LAYER. THE STUDY CONTAINS TWO PARTS. IN THE FIRST PART, SCALE ANALYSIS SHOWS THAT THE NATURAL CONVECTION PHENOMENON CONFORMS TO ONE OF FOUR POSSIBLE REGIMES, DEPENDING ON THE VALUES OF BUOYANCY RATIO AND LEWIS NUMBER. IN THE SECOND PART THE BOUNDARY-LAYER PROBLEM IS SOLVED VIA SIMILARITY FORMULATION IN THE BUOYANCY RATIO RANGE FROM -5 TO 4 AND LEWIS NUMBER RANGE FROM 1 TO 100.
