Under small external perturbations, the initial stage of the laminar into turbulent flow transition process in boundary layers is the development of natural oscillations, Tolman-Schlichting waves, which are described by the linear theory of hydrodyna

The results of an experimental investigation of the three-dimensional stability of a boundary layer with a pressure gradient are presented. A low-turbulence subsonic wind tunnel was employed. The development of a three-dimensional wave packet of osci

The first part of this paper (§2) briefly reviews the history of the idea of the resonant nature of laminar-boundary-layer breakdown. In the second part a new wave-resonance concept of the breakdown mechanism is proposed. The existing experimental d

In recent years definite progress has been achieved in the construction of theoretical models of nonlinear wave processes which lead to a transition from laminar to turbulent flow [1, 2]. At the same time, there is a shortage of actual experimental m

The three-dimensional resonant interaction of a plane Tollmien-Schlichting wave, having a frequencyf1, with a pair of oblique waves having frequencies ½f1, was observed and studied experimentally. In the initial stages, the interaction proved to be

The detailed analysis of nonlinear breakdown of a laminar boundary layer had been carried out in the fundamental experimental work [1]. The results of this work (a strong amplification of three-dimensionality, a sudden appearance of “spikes” and
