THE SEPARATION OF AXIALLY SYMMETRIC TURBULENT BOUNDARY LAYERS PART II :DETAILED MEASUREMENTS DJ THE BOUNDARY LAYERS ON SEVERAL SLENDER BODIES IN INCOMPRESSIBLE FLOW

摘要

Detailed measurements of turbulent boundary layer velocity profiles and shear stress distributions on three slender bodies of revolution in in¬compressible flow are presented. Comparison of the results with those found in two-dimensional flows indicates no appreciable influence of lateral curvature on the Law of the Wall or use of H ac a shape parameter for the outer region of the velocity profile except where the boundary layer thickness exceeds body radius.nValues of wall shear stress determined by the method of Clauser-Coles are in excellent agreement with values measured using a shear stress pitot tuba according to the method of Preston, while those predicted by the Ludwieg-Tillmann formula are greater than measured values in the adverse pressure gradient regions of the flows.
