| Abstract: | Vortex-induced vibration (VIV) of circular cylinders exists in many fields, including mechanical engineering and marine engineering. Many new research results have been obtained by many researchers in the last decade. The latest review of VIV was published nearly ten years ago. Therefore, it is necessary to conduct a detailed review on the research progress achieved during the last decade. This paper systematically summarizes the research findings on VIV of circular cylinders in the last decade, expounds the causality between the wake modes and their corresponding response branches, and analyzes the effects of the key factors on the VIV responses, such as the mass ratio, damping ratio and Reynolds number. After discussing the curve fitting formula of the maximum amplitude of VIV responses and its limitations, some suggestions are presented on the direction of future research on VIV of circular cylinders. |
