RÉSUMÉ
In this paper, direct numerical simulations of a jet impacting a mixing layer are presented for purpose of flow control. Two points of view are considered: a control jet impacting Kelvin-Helmholtz eddies as well as its impact on a three-dimensional mixing layer. The control of the two-dimensional vortices with a steady control jet has permitted to built a simplified open-loop, based on the vertical velocity at the impact region, in order to actively control these vortices. Results of the control of a turbulent mixing layer show that the streamwize location of the impact is crucial
