Structural Response and Wake Vortex Dynamics of Cylindrical Structures Undergoing VIV with Elliptic Trajectories

Vortex Induced Vibrations (VIV) of a pivoted circular cylinder were examined through experiments conducted in a water tunnel facility at the University of Calgary. The structural response and wake dynamics of the system were evaluated with the goal of quantitatively describing the attendant fluid-structure interaction. Experiments were performed at a fixed Reynolds number of 3100, a mass ratio of 10.8, and a range of reduced velocities, 4.42<U*
