Zhusupbekova* Kyrgyz National Agrarian University im. <...> Skryabina 68 Mederova, Bishkek, 720005, Kyrgyzstan Received 12.03.2015, received in revised form 27.07.2015, accepted 20.11.2015 The article deals with Gertler vortices in the boundary layer of fl uid applied typical range of variation of the wavelength of the vortices. <...> Formulated boundary problem for the typical shortwavelength regime. <...> The development of vortices Gertler in compressible, especially hypersonic fl ows, attracted by now considerable interest in the development of new technologies, namely the creation of new supersonic little turbulent wind tunnel and the design of hypersonic aircraft, which detect the position of the laminar-turbulent transition and fi nding the distributions and peak values of the heat fl ows are key elements. <...> In this article the mathematical model describing the nonlinear stage of development of disturbances in compressible boundary layer in the fi eld of centrifugal forces at large, but subcritical Reynolds numbers and Gertler. <...> This model is designed for the description of the vortices Gertler, and to describe the perturbed fl ows about local or periodic irregularities in the transverse direction or the other spatial disturbed fl ow. <...> For small amplitudes of perturbations of nonlinear boundary value problems are reduced to linear problems of the theory of stability, which so far developed only in fragments. <...> Based on the method of matched asymptotic expansions we studied some linear modes of perturbations in the fi eld of centrifugal forces <...>
