“…Recently, many investigations undertaken on natural convection in enclosures filled with porous media [1][2][3][4][5][6][7]. On the other hand, the conjugate heat convection in enclosures filled with porous medium has evoked much interest by many researchers due to its various practical applications such as cold storage installations and high performance insulation for buildings.…”

The conjugate natural convection heat transfer in a partially heated square porous enclosure had been studied numerically. The governing dimensionless equations are solved using COMSOL Multiphysics and Darcy model assumed to be used. The considering dimensionless parameters are modified Rayleigh number, finite wall thickness, thermal conductivity ratio and the heat source length. The results are presented in terms of streamlines, isotherms and local and average Nusselt number. The results indicate that; the heat transfer can be enhanced by increasing the modified Rayleigh number. When the heat source length increases, the local Nusselt number of fluid phase increases, while, a reverse behavior of the local Nusselt number along the heat source is found. As the Rayleigh number increase, the local Nusselt number for both fluid and solid phase increases, therefore, the heat transfer rate will be enhanced. On the other hand, when the thermal conductivity ratio increase, the local Nusselt number for the fluid phase increases, and the local Nusselt number along the heated wall decreases.

“…The average heat transfer rate is increased on increasing the heat source length and amplitude of the temperature profile. Basak et al [3] studied non-uniform heating on the bottom wall of a porous square cavity. The local heat transfer rate is higher at the middle of the bottom wall with sinusoidal heating but the overall average heat transfer of the wall is lower as compared to constant heating.…”

Numerical study has been performed to investigate the effects of location and height for the partitions located on the bottom wall of a square enclosure filled with porous media. This study starts considering the simplest enclosure with two partitions. The partitions are non-uniformly heated. The left and the top wall are cooled while the right and the bottom wall are adiabatic well. The location and height of two partitions are considered. The interested parameters are Darcy number (Da) from 10 −5 to 10 −1 , the value of Rayleigh number(Ra) is fixed at 10 5 and the Prandtl number (P r) is 0.71. The results are presented in forms of streamlines, isotherms and heatlines. It can be found that the flow field is single cell when the height of the partitions is less than 0.5. The flow field and heat transfer increase when the value of Darcy number is increased.
