“…Violette et al (2007) predicted the VIV of long structures using a wake oscillator model which was developed by Facchinetti et al (2004a), compared the predicted results with DNS and experimental results. However, the model presented by Facchinetti et al (2004a) fails in describing quantitatively the cylinder oscillation amplitude, and no relations have been developed between the model parameters in the model, which vary considerably from experiment to experiment (Skop and Griffin, 1973).…”

a b s t r a c tA two-dimensional (2-D) vortex-induced vibration (VIV) prediction model for high aspect ratio (L/D) riser subjected to uniform and sheared flow is studied in this paper. The nonlinear structure equations are considered. The near wake dynamics describing the fluctuating nature of vortex shedding is modeled using classical van der Pol equation. A new approach was applied to calibrate the empirical parameters in the wake oscillator model. Compared the predicted results with the experimental data and computational fluid dynamic (CFD) results. Good agreements are observed. It can be concluded that the present model can be used as simple computational tool in predicting some aspects of VIV of long flexible structures.

“…Extensive studies have been carried out to better understand fluid-structure interaction in case of vortex induced vibrations [1][2][3]. It is desirable to reach the phenomenon of lock in [4] where the vortex shedding frequency is in the near range of natural frequency.…”
