The objective of this research is the study the influence of aspect ratio A1 of fluid portion compared to the height of cavity, on the natural convection in a partially porous enclosure. A cylindrical heat source maintained at a uniform temperature is introduced into porous portion. The equations which describe the thermal transfer and the hydrodynamic flow are described by the Navier-Stokes equations modified by using the extension of Darcy-Brinkman and the energy equation. The results obtained are in the form of isotherm`s distribution, stream`s functions, the local and the average Nusselt numbers and the pressure. Correlations between these parameters and the aspect ratio are considered.
