Summary
The various kinds of coherent vortical structures are arise and interleave in conformance with determined order at formation of a homogeneous boundary layer. The features of regularity of development and sequence of these structures are analyzed on basis of the results of physical experiment. The following hypothesis is offered: the similar vortical structures arise under certain conditions in near wall area of turbulent boundary layer. The combined method of drag reduction, which is based on simultaneous using of several methods of action on coherent vortical structures of a boundary layer, has been elaborated. The theory of boundary layer receptivity of different disturbances and the methods of efficient friction drag reduction due to control of coherent vortical structures of the boundary layer was worked out.
