Abstract
Natural convection in a cube of magnetic fluid saturated porous medium is studied numerically using a Darcy flow model. The evolution of various flow patterns is investigated in a magnetic field parallel and normal to the temperature gradient. The results are presented in terms of average Nusselt number curves consisting of the solution branches of the convective patterns. It is found that the magnetic field enchances the heat transfer more effectively when oriented perpendicular to the temperature gradient. Figs 7, Refs 12.
