Abstract

The development of disturbances in the boundary layer after loss of stability is analyzed, concentrating on the three-dimensional nonlinear perturbing wave. A mechanism of secondary instability of the perturbing wave in the boundary layer is suggested and the role of this mechanism in generation of turbulence is examined. The calculations made are compared with experimental data and a statistical approach to the problem of hydrodynamic instability to reveal the role of secondary instability in the development of flow turbulence.
