Convective heat transfer in rotating ribbed tubes.
Author(s) : MORRIS W. D., RAHMAT ABADI K. F.
Type of article: Article
Summary
Depending on the rib geometry, heat transfer is improved by up to threefold in comparison with a smooth-walled circular tube at zero rotation. Results are presented for three rib geometries which are typical of those used in-turbine rotor blade cooling channels. With rotation Coriolis-induced secondary flows increase heat transfer on the trailing edge of the tube in comparison to the leading edge. The effect of centripetal buoyancy is also investigated and the combined effect of Coriolis forces and buoyancy is demonstrated.
