Free convective fluid flow and heat transfer in cavity domains has received considerable attention over the past few years and the importance of this problem is due to the broad spectrum of industrial applications and environmental situations.

The aim of this study is to investigate the effect of Darcian free convective heat transfer in a square cavity partially filled with porous media with spatial side-wall temperature. The left vertical wall is implicit to consume side-wall temperature, which is greater than the the right vertical wall, and the horizontal walls are adiabatic. The governing parameters of present Rayleigh number, Darcy number, wave number, and porous layer thickness. It is found that when the wave number increases, the expansion of the streamline circulation cell tend to increases horizontally. The isotherm patterns are raised with high intensity and with irregular-shaped next to the left wall by the increase of the wave number, while near to the cold wall, the isotherm patterns occur with vertical lines. The effect of various porous layer thickness on the average Nusselt number with Rayleigh number is also shown.
