Résumé

Ducted cavities are well-known configurations in pipe systems. Their aeroacoustic behavior is typical of the one observed in industrial situations for flow control devices like valves for example. It is found that, for some flow conditions, strong noise tones are radiated. In this paper, we study with the help of a 3D compressible turbulent computation a plane 3D geometry for which we have experimental data. The first objective of this work is to have a better understanding of the physical phenomena in order to try to find solutions when such problems occur in practical situations. The second objective is to test numerical approaches in order to be able to take into account more complex geometries like rounded corners that is a crucial point on a physical point of view.
