NON-ISOTHERMAL LAMINAR FLOW AND HEAT TRANSFER BETWEEN DISKS COROTATING IN A FIXED ENCLOSURE

摘要

This is a numerical investigation of the coupled laminar flow and heat transfer in the space between a pair of disks attached to a hub rotating about a vertical axis in a fixed cylindrical enclosure. A temperature variation is imposed in the fluid by setting the disks at different uniform temperatures, the temperature of the bottom disk being higher than that of the top disk. The Boussinesq approximation is used to characterize buoyancy forces in the momentum conservation equations.
