ABSTRAKT

This paper studies analytically the heat transfer enhancement when a porous layer was distributed equally at the two walls of a parallel plate channel subjected to constant heat flux. The flow and thermal fields were assumed to be fully developed. Flow in the porous region is governed by Brinkman extended non-Darcy flow and by Poiseuille flow in the fluid region. The effect of the parameters such as Darcy number (Da), porous fraction (γp) on velocity, skin friction coefficient, Nusselt number, and net change in Nusselt number are examined. The Nusselt number increases for porous fraction (γp≥0.6) as the Darcy number increases.
