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

This paper presents results obtained within the scope of a collaboration be tween the "Laboratoire de Mecanique et d'Acoustique" (Marseille, France), t he "Laboratoire de Mecanique des Fluides et d'Acoustique" of the Ecole Cent rale (Lyon, France) and the "Laboratoire de Vibrations et d'Acoustique" of the Institut National des Sciences Appliquees (Lyon, France). The main aspe ct of this collaboration is to establish a comparison between a measured an d 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 giv en. Some numerical results are also given. The spectral density of the acce leration of the shell is compared with experimental results.
