Intermittency in a Locally Forced Plane Couette Flow
Résumé
The plane Couette flow displays a globally subcritical transition to turbulence. When forced by a thin wire introduced in the central plane, the basic flow bifurcates towards a new state of streamwise vortices which break down through a complex spatiotemporal regime. When a bead is introduced in the central plane, only a few vortices are generated. Their destabilization occurs via a new type of temporal intermittency hard to understand within the framework of dynamical systems
