Abstract
Steady localized disturbances (streaky structures) of a laminar flow with boundary-layer separation behind a step on the surface are experimentally studied. The results of the present work explain the previously found specific features of the structure in various conditions of their generation and show that the development of such disturbances in the flow-separation zone is outside the framework of the classical theory of hydrodynamic stability for shear flows.
