Description Forced convection heat transfer across a circular cylinder rotating with a constant non-dimensional rotation rate (alpha) varying from 0 to 6 are investigated for Reynolds numbers of 20-160 and a Prandtl number of 0.7. Flow transitions is reported here for a wider range of Reynolds number and rotation rates. Heat transfer visualization technique using heatlines is implemented here, probably for the first time, in finite volume framework for the unsteady heat transfer problem in complex domain and used for heat flow analysis. Rotation can be used as a drag reduction and heat transfer suppression technique. (C) 2009
