Description |
Effect of channel-confinement and rotation on the flow and heat-transfer across a cylinder is studied for various blockage ratio (beta = 0-50%), nondimensional rotational velocity (alpha = 0-2), and Reynolds number (Re = 35-170). The cylinder is maintained at a constant wall temperature with air as the working fluid. Criss-cross motion of the shed-vortices is noticed for the channel-confined flow across a rotating cylinder at intermediate blockage ratio. The effect of channel-confinement (rotation) is an enhancement (reduction) in the drag force and heat transfer. A downward lift force is generated under the influence of counterclockwise rotation, which increases with increasing blockage ratio. Rotation and channel-confinement have a stabilizing effect and can be used for flow control.
