摘要：

This paper presents an experimental study of the vortex-induced vibration (VIV) of a spring-supported rigid cylinder, which is placed near a plane wall and could vibrate in the transverse direction to the free stream. It is considered as an extension of the widely studied VIV phenomenon of a stand-alone cylinder in steady uniform flow. The effects of varying the gap height (defined as the distance between the cylinder bottom and the wall surface) on the VIV characteristics, including the vibrating frequency and amplitude of the cylinder, are examined in detail. The motion of the cylinder and its wake patterns have been measured using Particle Image Velocimetry (PIV), in conjunction with direct measurements of the hydrodynamic forces (drag and lift) on the cylinder using a piezoelectric load cell.
