Experiments on relative receptivity of three-dimensional supersonic boundary layer to controlled disturbances and its development
Khristianovich Institute of Theoretical and Applied Mechanics 4/1 Institutskaya Str., Novosibirsk 630090, Russia
Results of the controlled disturbance experiments in the supersonic boundary layer on a swept wing are considered. The high-frequency glow discharge technique is used for the disturbance generation. The linear development of wave trains is tested in smooth and rough surface conditions of the models. The relative receptivity of a three-dimensional (3D) boundary layer to stationary and nonstationary disturbances is estimated. Obtained that by using microroughness elements located in a swept wing boundary layer, it is possible to get a damping effect on the linear development of a spatial wave packet in the near field of the disturbances source.
