Abstract
This paper presents an experimental investigation of convective heat transfer in a confined rectangular cavity packed with porous media, on the opposing vertical walls of which different temperatures are imposed. Measurements are made for each of two kinds of solid particles using three kinds of fluids, i.e. water, transformer oil and ethyl alcohol. The present experiments cover a wide range of Rayleigh number Ra∗ between 1 and 10 5, Prandtl number Pr∗ between 1 and 200 and geometrical aspect-ratio H W between 5 and 26. The experimental results indicate that Nusselt number Nu∗ is correlated by the following relationship: Nu∗ = 0.627 Pr∗ 0.130 ( H W ) −0.527 Ra∗ 0.463
