A nonlinear model of interaction of disturbances in the regime of coupled combinatorial relations is used to explain the dynamics of unstable waves. The model includes effects of self-action and combinatorial interaction of unstable waves. Considered effects in the boundary layer with M = 2 controlled disturbance large enough intensity. In the second case when M = 5,35 examines the interrelationship of two-dimensional perturbations of various nature – vortex and acoustic. Shows the direction of impact of the different components of the nonlinear process. Found that this model of the second order nonlinearity can accurately describe the features of longitudinal dynamics of plane waves. Keywords:
under-and supersonic boundary layer, hydrodynamic stability, laminar-turbulent transition.
