BOUNDARY FLOW ALONG A CIRCULAR CYLINDER

Abstract

The Karman-Prandtl mixing-length theory for fluid flow over a flat surface with a laminar sublayer near the boundary is adapted to the flow along an infinite circular cylinder on the supposition that flux of momentum inwards towards the boundary is controlled by a continuity condition arising from the radial nature of the convection. Experimental results for smooth and rough pipe flows are invoked to develop the nature of the boundary flow over a range of conditions from the quasi-smooth to the fully turbulent regimes. The drag coefficient for tangential friction is evaluated as a function of Reynolds number and surface roughness. Theoretical indications compare favorably with results from towing tests of stranded cables.
