Response of a thin cylindrical shell excited by a turbulent internal flow

This paper presents results obtained within the scope of a collaboration between the “Laboratoire de Mecanique et d'Acoustique” (Marseille, France), the “Laboratoire de Mecanique des Fluides et d'Acoustique” of the Ecole Centrale (Lyon, France) and the “Laboratoire de Vibrations et d'Acoustique” of the Institut National des Sciences Appliquees (Lyon, France). The main aspect of this collaboration is to establish a comparison between a measured and a model vibro-acoustics response of a thin cylindrical pipe excited by a turbulent internal flow. After a brief review of the literature, a model of the response of the shell, based on a matched asymptotic expansion, is given. Some numerical results are also given. The spectral density of the acceleration of the shell is compared with experimental results.
