Summary

THE PAPER PRESENTS A MODEL AND NUMERICAL RESULTS FOR TURBULENT NATURAL CONVECTION IN A CUBICAL ENCLOSURE HEATED FROM BELOW, COOLED ON A PORTION OF ONE VERTICALSIDE WALL AND INSULATED ON ALL OTHER SURFACES. A TOP VIEW OF THE VELOCITY VECTORS REVEALED A DOWNWARD SPIRAL FLOW NEAR THE SIDE WALLS ALONG THE COOLED VERTICAL WALL. A WEAK SPIRAL FLOW WAS ALSO FOUND ALONG THE SIDE WALLS NEAR THE WALL OPPOSING THE PARTIALLY COOLED ONE. A COAXIAL DOUBLE SPIRAL MOVEMENT, SIMILAR TO THAT PREVIOUSLY REPORTED FOR LAMINAR NATURAL CONVECTION, WAS FOUND FOR THE TIME-AVERAGED FLOW FIELD. THIS COMPUTING SCHEME IS EXPECTED TO BE APPLICABLE TO OTHERTHERMAL BOUNDARY CONDITIONS.
