Abstract

The fluid/structure interaction phenomena in Acoustics correspond to the sound radiation of a vibrating structure immersed in a fluid. The vibrations of the structure generate a perturbation of the pressure in the fluid and then the propagation of a signal.The many applications of this theme include Transportation Noise as well as Music. This paper presents some aspects of the numerical simulation of these phenomena along with some examples.
