Abstract
The nonlocal equations for two harmonics of the Tollmien — Schlichting wave and averaged parameters of the incompressible boundary layer on a plate are derived. Computed results show that the wave gives rise to a friction increase on the wall, and this increase becomes substantial when the ratio of the amplitudes of the second and main harmonics reaches 0.5.
