Understanding subsonic and transonic cavity flows

A computational investigation of the subsonic and transonic turbulent open flow over cavities was conducted. Simulations of these oscillatory flows we re generated through time-accurate solutions of the Reynolds-averaged form of the Navier-Stokes equations. The effect of turbulence was included throu gh the k-omega model. The results presented include calculations of the aco ustic pressure distributions along the cavity floor, which compare well wit h experiment. The results are then used to describe the behaviour of the fl ow.
