The present paper reports numerical results of mixed convection and surface radiation within a horizontal ventilated cavity heated from below and provided with an adiabatic thin partition on the heated surface.Air, a radiatively transparent medium, is considered to be the cooling fluid.The effect of the governing parameters, which are the Reynolds number, 200 Re 5000, the relative Vacuum Performance Kit height of the baffle, 0 Hb 0.75, and the emissivity of the walls, 0 1, on the fluid flow and heat transfer characteristics is studied in detail.The Beer Mugs maximum and mean temperatures, the ratio, QE/QL, of the heat quantities leaving the cavity through the exit, QE, and through the left vertical cold side, QL, are also presented versus the above controlling parameters.
