Natural convection in the boundary layer of a vertical wall of constant mass flux and temperature embedded in a darcy mass stratified porous medium

Résumé

This paper presents the analysis of the natural convection in the boundary layer of a vertical impermeable semi-infinite wall of constant mass flux and temperature embedded in a Newtonian fluid-saturated Darcy mass-stratified porous medium. Using the scale analysis method, this work determines the two possible successions of the heat and mass driven convection regimes that attain the equilibrium state along the wall. The finite difference method applied to the mathematical model verifies these successions for two particular parameter sets.
