Resonant properties of laminar and turbulent boundary layers

With the purpose of modeling of coherent structures m laminar and turbulent boundary layers on a plate the properties of the appropriate profiles of longitudinal speed are considered. The spectral characteristics of profiles were determined in temporary statement. A resonance between 3-dimentional Sqaire and Tollmien-Schlichting waves of a discrete spectrum, and also 3-wave resonance for the lowest mode of Tollmien-Schlichting waves are considered. The qualitative comparison with experimental results is carried out.
