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

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.

Vortex-Induced Vibration of a Vertical Riser

Vortex-induced vibration (VIV) often causes the fatigue of offshore slender structures, such as risers, mooring lines and pipelines. Detailed understanding of this fluid-structure interaction (FSI) phenomenon and an efficient prediction of such self-excited and self-sustained oscillations are required for the reliable estimation of the fatigue damage and the development of VIV suppression techniques.

Vortex-Induced Vibration of Two Tandem Flexible Cylinders

The interaction between cylindrical structures in tandem arrangement subject to vortex-induced vibration (VIV) is a common phenomenon in marine and civil engineering, such as risers, tension-leg platform (TLP) tendons, heat exchanger tubes and chimneys. When bluff structures are situated in the wake of other bluff bodies, their dynamic responses become very complex and different from the case where they are isolated.
