Context
Boundary layer detachmentwake turbulences…
• Decreasing performances• Energy losses
Flow control
• Increase global performances by local manipulations

Motivation
3 OTT Célestin – GDR Flow Control – Orléans 2017
v Highlighting dynamic mechanisms between jets and the turbulent boundary layer
v Definition of a metric of the effectiveness of a flow control solution
v Association flow control target à actuator configuration
v Creation of a experimental data base for future CFD studies
