| Abstract: | The process of nonlinear development of a local transverse disturbance on a concave surface is analyzed and the mechanism of formation of the resulting periodic structure is examined. Attention is concentrated on a qualitative analysis of the flow. Equations describing the development of a transverse disturbance in a laminar boundary layer are obtained on the basis of the asymptotic behavior of the Navier-Stokes equations as Re   . A solution describing the Taylor vortices formed between two coaxial cylinders when the inner cylinder rotates is obtained. The experimental data on Görtler vortices in boundary layers are analyzed.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 23–31, January–February, 1990. |
