Abstract

Natural convective heat transfer from a cooled cylinder in an enclosure containing water P.H. Oosthuizen & Z. Xu Heat Transfer Laboratory, Department of Mechanical Engineering, Queen's University Kingston, Ontario, Canada, K7L 3N6 ABSTRACT A numerical study of the flow about and heat transfer rate from a horizontal circular cylinder centrally mounted in square enclosure containing water has been undertaken. The side walls of the enclosure are heated to a uniform temperature that is higher than the temperature of the cylinder surface which is also uniform. The bottom of the enclosure is adiabatic and the surface is assumed to remain flat and be adiabatic. The temperature of the cylinder surface is near the temperature at which the density maximum occurs. It has been assumed that the flow is two-dimensional and steady and that fluid properties are constant except for the density change with temperature that gives rise to the buoyancy force. The governing equations, expre
