MIXED CONVECTION FLOW AND HEAT TRANSFER IN A VENTED ENCLOSURE FILLED PARTIALLY WITH A POROUS MEDIUM
RESUMO
Mixed convection flow and heat transfer in a vented enclosure filled partially with a porous medium was studied in this investigation for various pertinent parameters. The effects of solid-to-fluid thermal conductivity ratio, Darcy number, Richardson number, location of the porous layer, and width of the porous layer on the streamlines, isotherms, and temperature and velocity profiles at midsections of the enclosure were analyzed in this study. The generalized model of the momentum equation, which is also known as the Forchheimer−Brinkman extended Darcy model, was utilized in modeling the fluid motion inside the porous layer. The results of this investigation illustrated that the location and width of the porous layer have a significant effect on the streamlines and isotherm patterns within the enclosure. Moreover, flow- and heat-transfer activities within the enclosure were found to depreciate as the width of the porous layer increases. Finally, the results showed that as the conductivity ratio of the porous layer increases, the porous layer becomes more conductive.
