Two-Degree-of-Freedom Vortex-Induced Vibration of an Elastically Mounted Rigid Circular Cylinder

By Enhao Wang, Dr Qing Xiao

Vortex-induced vibration (VIV) of cylindrical structures is a common phenomenon in many engineering applications. Due to its significance, VIV has been extensively studied in recent years. In this study, three-dimensional (3D) numerical simulations of two-degree-of-freedom (2DOF) VIV of an elastically mounted rigid circular cylinder are carried out. The effect of the natural frequency ratio on the 2DOF VIV response of the cylinder and the three-dimensionality of the flow is investigated.
