Turbulent boundary layer of a viscous incompressible fluid past a flat plate is studied. The characteristic Reynolds number of the flow is assumed to be large with the boundary layer being thin. To analyze the problem, the method of multiple scales was applied, which allowed to investigate the steady secondary flow inside the turbulent boundary layer. At that, self-induced entrainment of fluid from the external flow is the main flow in this case, which ensures the supply of kinetic energy from the maximum speed zone to the turbulence generation zone near the streamlined wall. Secondary steady solutions were found analytically for the longitudinal velocity component. The approach obtained is applied to the flow in the channel and to free turbulence flows. The found solutions were compared with the available experimental data.
