Stability of a Laminar Flow at the Boundary of Uniform and Decelerating Flows

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Conditions are obtained for the loss of stability of laminar motion at the boundary of uniform and decelerating flows, where the maximum drop in velocity occurs due to periodic deceleration of the fluid in the second section. At the end of the cycle, a local minimum with two inflection points appears on the flow velocity profile, and a vortex forms at the upper inflection point above the viscous layer. An estimate of the period of vortex formation is obtained.
