A property of a boundary layer with back streaming
Abstract
Prandtl's classical boundary layer theory is supported by numerous theoretical and experimental data for nonseparated flows in which the longitudinal component of the velocity vector does not change its direction. In the case of separated flow with recirculation regions, such regions can sometimes be treated as boundary layers of much greater relative thickness. The validity of such an approach is demonstrated here by analyzing certain exact (self-similar) solutions to the Prandtl equation. In all the solutions considered, the back streams are separated from incoming flow by mixing layers.
