Abstract
The influence of non-Darcian flow phenomena on the natural convection heat transfer from a vertical plate fin embedded in a porous medium was studied. With the thin-fin approximation for the plate fin and the non-Darcy flow model for the convective fluid, numerical solutions were generated to demonstrate the importance of non-Darcian effects on conjugate natural convection flow adjacent to the fin. These effects, which are often involved in convective transport of fluid through porous media, include high-flow-rate inertial force, solid-boundary viscous resistance, nonuniform porosity distribution, and thermal dispersion. The present work aims to investigate these effects on the fin heat-transfer characteristics such as fin temperature distributions, the local heat transfer coefficient, the local heat flux, and the overall rate of heat transfer.
