Abstract
This numerical study documents the effect of an adiabatic internal flow partition on natural convection heat transfer in a two dimensional enclosure filled with saturated porous media whereas the partition attached vertically on the lower insolated wall. The study concluded the effect of partition using different lengths (LP=0.3, 0.5 and 0.7), locations (XP=0.3, 0.5 and 0.7) and different inertia effect (Fs/Pr=10-2, 10-3 and 10-4) on heat transfer with aspect ratio (A=1.0). A continuity, energy and momentum equations are analyzed and solved using finite difference with Gauss-siedel iterative method. From results, it’s clear that the partition caused a deflection on stream lines causing a disturbance in the flow patterns. This affected the heat transfer rate represented by Nusselt number. Also, for a wide range of governing parameter, it may be concluded that the partition reduces the heat transfer rate.
