The structure of an unsteady flow past a rectangular, open cavity is investigated using numerical simulations. Particular attention is drawn to the effects of the laminar or turbulent state of the incoming boundary layer. The consequences on noise generation are studied using Direct Noise Computation, solving the filtered 3-D compressible Navier-Stokes equations. The turbulence level and the shear strength before the separation corner are seen to influence the large-amplitude oscillations in the cavity.
