Cover Story: The suppression of the cavity tone by plasma actuators was investigated by the computations along with experiments. The figure shows the predicted iso-surfaces of the second invariant color-coded by values of the streamwise vorticity for phase-averaged flow fields at the phase where the vortex collides with the downstream edge of the cavity for controlled flow by plasma actuators. It is shown that the streamwise vortices are generated by the actuators in the upstream of the cavity. These vortices weaken and deform the two-dimensional vortices responsible for the cavity tone, which leads to the reduction of the cavity tone. View this paper
