Abstract

The natural convection flow from a heat point source embedded in a non-Darcian porous medium is investigated by employing local similarity and modified Keller's Box methods. The non-Darcian effects of convective, inertia and thermal dispersion are all considered. The results indicate that the non-Darcian effects decrease the centerline velocity and temperature and also increase the velocity and temperature boundary layer thicknesses. In addition, solutions using the local similarity method over-estimate the centerline velocity and temperature.
