Abstract：With CFD method， the characteristics of Vortex-Induced Vibration for a Circular Cylinder at High Reynolds Number are studied. Navier-Stokes equation and the circular cylinder’ movement equation are solved by the software FLUENT. With the dynamic mesh of FLUENT， one-way and two-way fluid-structure interaction VIV are simulated. Through this paper， the lift coefficient and the drag coefficient and the amplitude ratio and the vortex shedding frequency ratio between the Reynolds Number are obtained; the “lock-in” and “phase switch “were confirmed.The results show that in this Reynolds number range， the corresponding lock region is for Ur = 3 ~ 7.5 .The results of one-way and two-way VIV simulation show that larger damp will weaken the VIV level， and in the low quality， small damping， longitudinal freedom vortex-induced vibration will aggravate transverse vibration.
