Résumé

In this paper, the authors investigate the phenomenon of conjugate free convection in a semi-infinite porous medium above a heated finite plate. Numerical solutions of the full governing equations for the fluid region, coupled to the heat conduction equation in the finite plate, are obtained for a wide range of the non-dimensional parameters appearing in the problem, which are the Rayleigh number, Ra, the ratio of the thermal conductivities of the finite plate and the fluid, kappa, and the aspect ratio of the finite plate, lambda; a detailed description of the effects of these parameters on the characteristics of the fluid flow and the heat transfer in the fluid is provided.
