Abstract
Scale analysis of coupled heat and mass transfer from a point or a horizontal line source in an infinite saturated porous medium is reported is this paper. Conservation equations are shown to have solutions of similarity form for generalized variables in the case of flow when dispersion is predominant over molecular diffusion. Closedform solutions are presented for Darcy and non-Darcy natural convection for both point and line sources. The estimations of distances from sources where the solutions obtained will be valid are given.
