The purpose is to control in an optimal way a compressible flow based on Direct Numerical Simulations (DNS) using as starting point directo code and ismulations of adjoint equations based on adjoint code. Once done, a validation for the control implementation has been done (link between optimized code, direct code and adjoint code) in order to test several configurations (different control and observation zones, different control and observation variables). A physical analysis showed up effects on the flow and acoustic emissions
