Abstrakt

The present study was focused in clarifying characteristics of natural convection in the vertical cylinder with a eccentrically located source of internal heating. Experiments were performed by using water as a simulating fluid and a small electric coil heater as a internal heat source. Temperature distributions in a test cylinder made of acrylic resin were measured, which were estimated well with the following numerical analyses. Three-dimensional numerical analyses were performed by using a numerical schema with control volume formulations. Velocity and temperature distributions in the cylinder, and Nusselt number distributions on the top cooling surface were analyzed. The flow and heat transfer were strongly influenced by the eccentrically located source of internal heating and the difference of thermal conductivity between water and liquid sodium. In both fluids, the flow patterns were three-dimensional and asymmetrical.
