A Numerical Investigation of Natural Convection in Porous Media

Abstract

<p> A semi-explicit scheme for the solution of transient multdimensional natural convection is made to study natural convection in porous media. The conservation equations are phrased in primitive form. Heat tranfer between the solid and liquid phases is modelled by representing the porous medium as an assemblage of spherical particles, and solving the conduction problem for such a system at every time step. Nusselt numbers were calculated from the temperature and velocity profiles. Numerical results for heat transfer through fluid saturated porous media heated from below are in good agreement with published experiments.</p>
