• F141 Flow analysis of the Vortex-Induced Vibration of a Circular Cylinder in high Reynolds Number Flow

抄録

In CO_2 ocean sequestartion with a moving ship, oscillation of CO_2 releasing pipe by vortex induced vibration (VIV) is potential source to increase hydraulic resistance and possibly causes mechanical damage on the pipe. Wake flow formed behind the releasing pipe is to be a highly turbulent flow over critical Reynolds number. It is important to fundamentally elucidate generating mechanism of VIV around a cylinder. In this study, we investigated VIV behaviors and flow structure behind a cylinder by measuring two-dimensional velocity field with time-series particle image velocimetry (PIV). It was confirmed that oscillation of the cylinder was amplified in accordance with periodical vortex sheddling.
