    Abstract:
    This paper outlines a combined theoretical and numerical study of the mass transfer effected by high Rayleigh number Bernard convection in a two-dimensional saturated porous layer heated from below. The focus of this study is on the Darcy flow, heat transfer and mass transfer scales of a single cell (roll) that exists in the steady two-dimensional convection regime. The numerical solutions are based on the complete governing equations for two-dimensional flow, and cover the Rayleigh number range 50-2000. The numerical results compare favorably with the theoretical conclusions of a scale analysis.
