AB  - The conjugate natural convection heat transfer in a partially heated porous enclosure had been studied numerically. The governing dimensionless 
equations are solved using finite element method. Classical Darcy model have been used and the considering dimensionless parameters are modified 
Rayleigh number (10 ≤ Ra ≤ 10<sup>3</sup>), finite wall thickness (0.02 ≤ D ≤ 0.5), thermal conductivity ratio (0.1 ≤ K<sub>r</sub> ≤ 10), and the aspect ratio (0.5 ≤ A≤ 10). 
The results are presented in terms of streamlines, isotherms and local and average Nusselt number. The results indicate that heat transfer can be 
enhanced by increasing the modified Rayleigh number, and thermal conductivity ratio. Wall thickness effects on the heat transfer mechanism had 
been studied and it is found that; as the Wall thickness increases, the conduction heat transfer mechanism will be dominated. Also, increasing aspect 
ratio will increase the stream function and reduced the heat transfer rate.
