Numerical simulation of vortex induced vibration of a circular cylinder using a CIP-based model

摘要：

　　Vortex induced vibration (VIV) is extensively applied in engineering, for instance, subsea pipelines, marine risers,bridge engineering, etc.The structures may be destroyed under large amplitude vibration, so the VIV problem has induced plenty of researches.In this paper, A CIP-ZJU model is developed to study the VIV of a circular cylinder at Re=100.The circular cylinder is free to vibrate 2 ways, 1 degree of freedom (DOF) and 2 DOF.The synchronization or lock-in phenomenon is observed.The dynamic response, vibration frequency and flow field is studied.The results are compared with existing literatures and show reliable agreement, indicating the present model can simulate VIV problem effectively.
