Coupled CFD and CAA analogies were used to capture the wake and far-field noise propagation in 2D simulations. Farassat 1A formulation of Ffowcs Williams-Hawkings (FW-H) equation is used to capture the far-field pressure fluctuations. Effect of active control on the percentage reduction in vortex strength downstream and overall BVI noise is investigated.falseActive control method | Blade-Vortex Interaction | Computational aero-acousticsConference Paper21954364547-55320221cpBook Series0
