The present work concerns with the heat transfer by natural convection and radiation in an annular cone fixed with saturated porous medium. The Darcy model is used to predict the heat transfer behavior in the porous medium. The surface of the cone is maintained isothermally. The partial differential equations are nondimensionalized using suitable nondimensional parameters. The finite element method is used in this study. Computer code is generated to solve the coupled energy and momentum equations. Results are reported for average Nusselt number against different cone angles, radiation parameter, Rayliegh number, radius ratio. It is observed that the cone angle plays an important role in heat transfer from the surface of the cone to the porous medium.
