Copyright © 2018 by the International Society of Offshore and Polar Engineers (ISOPE) In the past decades, sinusoidal motion of a circular cylinder in viscous flow had been extensively studied by researchers all around the world. While difference of flow patterns exists between fixed cylinder and freely vibrating cylinder. In this paper, numerical simulations are carried out by the in-house CFD code naoe-FOAM-SJTU with overset grid capability, which is developed based on the open source code OpenFOAM. The diameter of the cylinder is 0.02m and the KC numbers vary from 3 to 15. Results of vortex evolution, flow regimes and separation points of the cylinder with cross-flow freedom restricted and freely vibrating are compared.
