Abstract
This study investigates the convection effects of adding non-Darcy porous media to open enclosures with diagonally placed hot baffles near the open ports. The cold wall is fixed at the right side of the cavity. The remaining sidewalls are adiabatic. The fluid enters the enclosure from the inlet in the left vertical wall and leaves from an outlet at the right vertical wall. The finite difference method is employed to discretize the governing equations. The problem is analyzed for various parameters, Rayleigh number ([Formula: see text]), length of heating baffles ([Formula: see text]), porosity of the porous medium ([Formula: see text]), Reynolds number ([Formula: see text]) and Darcy number ([Formula: see text]) at alternate configured vented cavities and the results are illustrated graphically. The observation shows maximum heat transfer attained at BT open enclosure regardless of various parameters. For [Formula: see text] considerable increase in the heat transfer occurs at the right sidewall when the porosity of porous medium increases. The impact of configurations on heat transfer along the right wall is negligible at low Reynolds numbers but becomes significant at high Reynolds numbers.
