Analytical solution for a vibrating simply-supported cylinder subjected to 2-D concentric annular flow, considering friction

An analytical model of annular-flow-induced vibration of a pinned–pinned cylinder is proposed. The model is based on three main assumptions: (i) small perturbations in flow components, (ii) negligible radial flow to reduce the annular flow to two-dimensional flow, and axial flow only for reduction t...
