摘要：By applying an overlapping mesh, a vortex-induced vibration (VIV) model was constructed and the effect of several key factors on VIV: mass ratio m *, Reynolds number Re and, reduced velocity Vr = U/fND was investigated. By assuming A/D = f(m*, Re, Vr), parameter analysis was taken about influence of the three parameters on A/D, and especially, the two terms of Cl which is in phase with velocity (Clv) or is in phase with acceleration (C la) are computed respectively, the contours of them were plotted. It was found that the maximum cross-flow amplitudes are 3  6 times of those in in-line direction. Response and fluid forces achieve their peak values as V r is around 6  7 and Re is about 2.2  104, inside the so-called concentrate area, Re has a linear influence on A/D, but outside, Re has little effect on them. On the other hand, Vr basically has linear influence on Clv, Cla, while Re has slight effect on them. ? 2010 by The International Society of Offshore and Polar Engineers (ISOPE).
