title = "Adjoint-based control of the noise from a turbulent mixing layer",
abstract = "We have developed an adjoint-based control methodology that circumvents the complexities in a free shear flow and allows us to study noise control directly. Though it is potentially more general, we have developed and implemented it within a direct numerical simulation (DNS) framework and demonstrated it on a two-dimensional mixing layer. It reduced noise in a target region by over 90%, and allowed us to investigate the subtle flow changes leading to this reduction. Currently, a three-dimensional turbulent mixing layer has been simulated and controlled via the adjoint method. Preliminary results show a corresponding 28% reduction, with simulations ongoing.",
