Abstract
A direct numerical simulation of the sound radiated by a flow over a 2-D subsonic cavity is performed using Computational AeroAcoustics tools. The simulation is consistent with Karamcheti's experiments. The numerical results are used as a reference to study two integral formulations: the Ffowcs Williams and Hawkings acoustic analogy and a wave extrapolation method based on FW-H equation. These hybrid approaches agree with the direct computation by DNS data and provide powerful tools to compute far-field noise. To cite this article: X. Gloerfelt et al., C. R.
