Numerical study of vortex-induced vibration of a circular cylinder

The present study aims to explore the dynamical behavior in the uniform flow by
numerical method. The theoretical model is based on transient of continuity equation and
momentum equation in CFD software: Fluent. With User Define Function¡]UDF¡^, we can
simulate the Vortex-induced vibration¡]VIV¡^under the uniform flow by numerical method
and plot the contour of amplitude and flow field under different Reynolds number. We will
identify the accurate and capable of central difference method in UDF by comparing with the
previous study. Also, we focus on whether the amplitude and flow situation will effect by
uniform flow in different degrees or not. Furthermore, this study shows how the time step
size and mesh effect the conclusion so that we could have the best choice on model.
