Mechanisms of vortex-induced vibrations of a D-section prism at subcritical Reynolds number
This paper presents a systematic investigation of vortex-induced vibration (VIV) of a D-section prism at subcritical Re. It is found that the response is persistently VIV typed, which can be excited and sustained by the viscous and/or pressure lift coefficient. Galloping is found to be absent because it requires an unstable structural mode with a frequency close to the prism natural frequency and flow mode with the natural vortex shedding frequency.
