Description

In this paper, the stability of the thin cylindrical shell subjected to an axial leakage flow is reported. We focus on the circumferential (ovaling) vibration of a shell in this study. Equations for a shell and a fluid are described by the Donnell's shell theory, and the Navier-Stokes equation respectively, and the coupled equations are derived. As a result, the added mass, added damping and added stiffness are calculated. The influence of the axial velocity on the unstable phenomena is clarified. The numerical simulations are shown as parameter studies.
