Jet-noise control by fluidic injection from a rotating plug: linear and nonlinear sound-source mechanisms

We present a study of the turbulent and acoustic fields of subsonic jets, controlled by means of a novel actuator that introduces perturbations via steady-fluidic actuation from a rotating centrebody. The actuation can produce louder or quieter jets, and these are analysed using time-resolved stereo...
