Abstract

The cycle of experimental investigations showed that the applied method of introducing controlled perturbations allowed to quantitatively and qualitatively investigate the occurrence and development of artificial disturbances in the subsonic boundary layer. The detected feature of localized impact consists in the simultaneous excitation of various types of disturbances in the boundary layer, such as longitudinal streaky structures and wave packets. The explicit correlation of the characteristics and features of development between the generated in the experiment perturbations and intrinsic boundary layer perturbations allow to conclude about the general nature of the perturbations under study, regardless of the way they are excited.
