Abstract

This paper aims to analyze the diffusion of heat and mass in porous material, caused by thermal gradients created by two heating sources. The first heating source is a full surface of the cavity at left side. The second heating source is a small strip that is placed at x = L/4 with L indicating the length of cavity. The concentration gradient is maintained in the porous domain due to the high concentration at left surface and low concentration at right surface. The investigation is focused to evaluate the heat as well as mass diffusion due to strip height, Lewis number, Rayleigh number, buoyancy ratio, and radiation parameter. The solution is obtained by dividing the whole domain into smaller elements of triangular shape with each element having three nodes placed at the corner of triangle. Galerkin approach is utilized to get the finite element formulations of governing equations. The concentration distribution gets affected due to the heat source placed toward the left surface.
