“…The problem of thermal convection for such a configuration in a vertical enclosure where the porous layer is parallel to the vertical walls has been studied in the context of wall insulation (Arquis and Caltagirone, 1984;Sathe et al, 1988;Lebreton et al, 1991) or solidification (Beckermann et al, 1987b(Beckermann et al, , 1988Song and Viskanta, 1994). An exact solution has been proposed by Weisman et al (1999) and the stability problem has been tackled by Mercier et al (2002).…”

AbstractPurpose -This paper aims to provide a limited, but selective bibliography on modelling heat and mass transfer in composite fluid-porous domains. Design/methodology/approach -Since the pioneer study by Beavers and Joseph, the problem of interface continuity and/or jump conditions at a fluid-porous interface has been of interest to the fluid mechanics and heat and mass transfer community. The paper is concerned both with numerical simulations of heat and fluid flow in such systems, and with the linear stability problems. Findings -The one-and two-domain formulations are equivalent. Using the Darcy-Brinkman extension instead of the Darcy model reduces the number of ad hoc parameters in this configuration.Research limitations/implications -The problem of double diffusive convection has still to be solved and analyzed. Practical implications -The discussion on the interface conditions is of great relevance to many industrial and practical situations. Originality/value -The important question of the macroscopic formulation of the problem is tackled in the paper.

“…Their results showed that the intensity of the natural convection is always much stronger in the fluid region than in the porous medium and the degree of penetration of the fluid into the porous layer depends on the permeability of the porous layer as well as with increasing Rayleigh number. Song and Viskanta [15] studied experimentally and theoretically the free convection fluid flow and heat transfer inside a rectangular enclosure partially filled with an anisotropic medium. They found that the effect of the anisotropic permeability on the average Nusselt number is most significant when the fluid flow is just strong enough to affect the heat transfer.…”
