Résumé

The lecture focuses on control of the near-wall and free shear layers emphasizing the control goals and approaches to modification of the flow characteristics. The control methods, both implemented in practice and prospective ones, employing effects of hydrodynamic instability are under the consideration. In some cases, their application makes it possible to modify local and global flow characteristics at a rather small level of the external forcing generating the controlled shear-layer perturbations.
