Summary

TWO-DIMENSIONAL STEADY NATURAL CONVECTION IN A POROUS RECTANGULAR CAVITY BOUNDED BY ISOTHERMAL VERTICAL WALLS AT DIFFERENT TEMPERATURES AND ADIABATIC HORIZONTAL WALLS HAS BEEN STUDIED NUMERICALLY FOR ASPECT RATIOS LESS THAN UNITY AND RAYLEIGH NUMBERS UP TO 10,000. RESULTS INDICATE THE PRESENCE OF MULTICELLULAR FLOW. ALSO, THE AVERAGE NUSSELT NUMBER BASED ON CAVITY WIDTH IS OBSERVED TO BE A MAXIMUM IN A RESTRICTED RANGE OF ASPECT RATIO, DEPENDING ON THE RAYLEIGH NUMBER.
