Visualization of the Interaction of Weak Disturbances of a Flow with the Boundary Layer

Results of experimental investigations of flows around wedge-shaped obstacles of different height installed in a supersonic conical nozzle at M = 2.7 by the methods of color surface visualization and "laser knife" are presented. The influence of the interaction of weak disturbances of these flows by the passive side of the obstacles with the boundary layer on their structure and behavior was determined. The side force of the nozzle was measured.
