Copyright © 2017 by the International Society of Offshore and Polar Engineers (ISOPE).The CFD simulations of vortex-induced vibrations of a flexible cylinder in oscillatory flow have been numerically investigated based on the strip theory. The algorithm PIMPLE in OpenFOAM is adopted to compute the flow field while the small displacement Bernoulli-Euler bending beam theory is used to model the cylinder. Two ends of the flexible cylinder are forced to oscillate harmonically. Features such as the hysteresis between the decelerating and the accelerating stages and the build-up-lock-in-die-out cycle are observed.
