Convection heat transfer in a rectangular cavity packed with spherical particles whose bottom and upper boundaries are heated and exposed to a forced convection flow is examined numerically. A simple analytical formula of the interface between the fluid and porous layers for calculating the heat transfer is presented. Mixed, forced and natural convection through a porous layer is considered. The numerical results for the mixed convection are in good agreement with considered. The numerical results for the mixed convection are in good agreement with experimental data. It is shown that the Nusselt number is dominated by the Reynolds number, a modified Rayleigh number and a geometrical aspect ratio (depth to width of the porous layer).
