SINOPSIS
The paper presents the results of an experimental study of the laminar-to-turbulent boundary layer transition in directed injection along the flow and opposite to it. The effect of the value of the angle and intensity of injection on the start and end of the transition was determined. The moment of the start and end of the transition to a turbulent mode was determined by the dependence of the value of a maximum intensity of velocity fluctuations across a boundary layer cross-section on the intensity of injection. The experiments were performed at the angles of injection of 20°, 45°, 65°, 115°, 135°, and 160°. The intensity of injection varied from 0.3% to 3.2%.
