Examination of Anisotropy of Reynolds Stress Tensor Downstream of a Short Roughness Strip and Concentrated Wall Suction in a Turbulent Boundary Layer

ABSTRAKT

Hot wire measurements have been made in a turbulent boundary layer subjected to concentrated wall suction and impulse in form of a short roughness strip with the aim of examining their effects on the anisotropy of the Reynolds stress tensor. The results indicate that, while suction increases the anisotropy of the layer, the degree of the anisotropy is altered at the present of the roughness strip. The combination of suction and roughness strip modified the scale of the near-wall structures as reflected in the change in the streamwise and wall-normal integral length scales.
