The results of investigations under centrifugal forces transitional boundary layers as well as the spatio-temporal properties of boundary layers vortical structures are presented. It has been shown that in case of boundary layer flows under centrifugal forces the small parameter depending on the value of these forces can be introduced. Using methods of matching asymptotical expansions the scenarios of the boundary layers development (including transition processes from 2D to 3D) in terms of space scales of their vortical structures have been proposed. In particular, the knowledge about (i) formation mechanisms of 3D vortical structures in boundary layers; (ii) spatio-temporal properties of 2D and 3D vortical structures depending on basic flow parameters were obtained. |
