Abstract

The results of experimental researches of the influence of cross streamlined semi-cylindrical cavity on the mean and fluctuation longitudinal velocity components along the plate and above the cavity are presented. Investigations are carried out for laminar and turbulent conditions of airflow. It is shown that the cross streamlined semi-cylindrical cavity on the flat surface changes the boundary layer structure, forming the acceleration and stagnation zones of the current above the plate. The longitudinal fluctuation velocity are increased into near- wall and logarithmic regions of the boundary layer with the increase of air-flow velocity but mean longitudinal velocities are decreased both above the cavity and in the vicinity of cavity throughout the boundary layer thickness
