Measurements of turbulent boundary layer growth over a longitudinally curved surface
Abstract
Measurements are presented of mean and fluctuating quantities in the turbulent boundary layers on the concave and convex walls of a curved duct, the radius of curvature being of the order of 100 times the boundary layer thickness in each case. Curvature of this magnitude causes changes in surface shear stress of about 10 percent with corresponding changes in Reynolds stresses. Longitudinal vortices occurring on the concave wall are briefly documented.
