 Abstract

A CFD study is made to get more insight in the flow, temperature and heat distribution in a side heated cavity filled with coarse grained porous media. This was investigated for 105≤Ra≤107 and 0.01≤Ri≤100. The question is how the solid beads influence the heat transfer. It was found that the spheres dampen the flow, influence the local heat transfer rate and affect the ratio of natural to forced convection (expressed with the Ri number). A modification was proposed by multiplying Ri with the square root of Da to take the influence of the spheres into account.
