Summary

THEORETICAL INVESTIGATION ON THE INTERACTION BETWEEN FILM CONDENSATION AND NATURAL CONVECTION ALONG A VERTICAL WALL SEPARATING A FLUID RESERVOIR FROM A FLUID-SATURATED POROUS RESERVOIR. THE TWO RESERVOIRS ARE MAINTAINED AT DIFFERENT TEMPERATURES. THE STUDY CONSISTS OF TWO PARTS: IN THE FIRST PART THE CONDENSATION PHENOMENON TAKES PLACE IN THE FLUID RESERVOIR AND THE NATURAL CONVECTION PHENOMENON IN THE POROUS LAYER. IN THE SECOND PART, THE OPPOSITE SITUATION IS CONSIDERED. THE MAIN CHARACTERISTICS IN THE TWO COUNTERFLOWING LAYERS ARE DOCUMENTED FOR A WIDE RANGE OF THE PROBLEM PARAMETERS. THESE PARAMETERS APPEAR AFTER BOUNDARY LAYER SCALING OF THE GOVERNING EQUATIONS. FINALLY, THE EFFECT OF THE THERMAL RESISTANCE OF THE WALL CONSTITUTING THE INTERFACE SEPARATING THE TWO RESERVOIRS, ON THE OVERALL HEAT FLUX FROM THE CONDENSATION SIDE TO THE NATURAL CONVECTION SIDE IS DETERMINED.
