THE PULSATION STRUCTIRE OF GAS FLOW IN THE DEVELOPED TURBULENT BOUNDARY LAYER. THEORETICAL ANALYSIS
Abstract
The weakly nonlinear variant of the wave model of the developed turbulent boundary layer is considered. Dispersion properties of the least damping Tollmien-Schlihting waves are defined and conditions of 3-wave resonance existence are given. Equations for the coherent and the stochastic part of the pulsations are received by the multiscale method.
