Abstract

Hot-wire measurements have been carried out in a turbulent boundary layer subjected to concentrated suction applied through a short porous wall strip with a view to examine the effect suction can have on the anisotropy of the Reynolds stress tensor. The departure of the Reynolds stress ratios from their corresponding values in the undisturbed flow is increased as the normalised suction rate increases. It is argued that the alteration to the Reynolds stress containing motion reflects a “cigar” to “pancake” change in the shape of the structures near the wall.
