Resum:
This review provides a comprehensive analysis of the literature on vortex- induced vibration (VIV) of flexible circular cylinders in cross-flow. It delves into the details of the underlying physics governing the VIV dynamics of cylinders characterized by low mass damping and high aspect ratio, subject to both uniform and shear flows. It compiles decades of experimental in- vestigations, modeling efforts, and numerical simulations and describes the fundamental findings in the field. Key focal points include but are not limited to amplitude-frequency response behavior, the relationship between the dis- tributed loading acting on the cylinder and the trajectories and the near wake structures around the cylinder, the existence of traveling waves, the identifi- cation of power-in/power-out regions, and the modal overlapping and mode competition phenomena.
