Flow-induced vibration of a D-shape cylinder

Abstract

This study investigates the dynamic response of transverse flow-induced vibrations of an elastically-mounted D-shape cylinder oriented at two different angles of attack, α = 0◦ and 180◦, in a free-stream. The results show that two typical body oscillator phenomena of FIV, vortex-induced vibration (VIV) and transverse galloping, can occur in different flow regimes for α = 0◦, while pure VIV response is observed for α = 180◦ over the flow reduced velocity range investigated (2 ≤ U*
≤ 12). This suggests that there exists a transition to a VIV-galloping response with variation of the angle of attack.
