We investigate the nature of heat transfer and entropy generation for natural convection in a two-dimensional circular section enclosure.The enclosure is assumed to Photo Paper fill with porous media.The Darcy momentum equation is used to model the porous media.

The full governing differential equations are simplified with the Boussinesq approximation and solved by a adjustment slide finite volume method.Whereas the Prandtl number Pr is fixed to 1.0.

Results are presented in terms of Nusselt number, entropy generation number, and Bejan number.
