Séminaire M. GARCIA le 23 février 2011

Optimal noise control emitted in a cavity by a two-dimensional compressible flow
23 février 2011 à 11h
Salle Castex

Résumé :
The purpose is to control in an optimal way, a compressible flow based on Direct
Numerical Simulations (DNS) using as starting point direct code and simulations of adjoint equations based on adjoint code. Control is an optimization of the noise equation and a joint gradient algorithm has been used for it. 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 control effects on the flow and acoustic emissions.
