Different passive control strategies have been applied to a 2D cavity with a length-to-depth ratio (L/D) of 5 with the aim of reducing the high noise levels generated inside the cavity. The effectiveness of spoilers and slanted cavity walls was assessed using the Unsteady Reynolds-Averaged Navier-Stokes equations. Steady jet blowing was also attempted and proved to the be most effective method achieving high noise level suppression and almost complete elimination of the frequency content.
