Self-preservation for a turbulent boundary layer over a d-type rough surface
Abstract
The results of an analytical and experimental investigation of self-preservation in a boundary layer with zero pressure gradient over a d-type rough surface are presented. An exact determination was made of the wall shear stress from measurements with a floating element apparatus. The skin friction coefficient was found to remain nearly constant. Further study of the velocity and turbulence characteristics indicated that the d-type rough wall turbulent boundary layer conforms to Rotta's condition for a self-preserving flow.
