Abstract This paper presents preliminary results from an acoustic post processor for incompressible, viscous computations. The method is applied to the two-dimensional problem of grazing flow past a cavity. A research RANS code is used to obtain the incompressible flow field quantities. Subsequently, the acoustic calculation is performed using a second-order finite-difference scheme. The method is shown to be a viable strategy for obtaining predictions for the acoustic field associated with a viscous, subsonic flow.
