Abstract
This article presents an attempt to understand the heat transfer behaviour due to heat supplied through a small block in the porous medium from its outside vertical and horizontal surfaces. The heat transfer in the porous medium is assumed to follow Darcy law. The right vertical surface of porous cavity is maintained at isothermal temperature Tc which is lesser than that of heat supplied by isothermal block. The governing equations are solved with the help of finite element method by using a 2-dimesnional triangular element. The results are discussed with respect to the Thermal conductivity ratio, Rayleigh number, Radiation parameter etc.
