Laminar forced convection from a rotating cylinder
Abstract
The problem of laminar forced convective heat transfer from an isothermal circular cylinder rotating about its own axis and placed in a uniform stream is considered. The direction of the forced flow of the cooling fluid is assumed to be normal to the cylinder axis. The study is based on the solution of the unsteady twodimensional conservation equations of mass, momentum and energy. The problem is solved for Reynolds number (based on the free stream velocity) up to Re = 100 and for velocity ratios (ratio between cylinder circumferential velocity and free stream velocity) up to alpha = 4. Major emphasis is given to the effect of the speed of rotation on the thermal boundary layer geometry, and also on the local Nusselt number distribution.
