AbstractThe in-line Vortex-induced Vibration (VIV) characteristics of a circular cylinder are investigated. A wake oscillator model is used for the in-line dynamic response prediction in the second excitation region. The near wake dynamics related with the fluctuating nature of vortex shedding is modeled based on the van der Pol equation. The influences of mass-damping parameter, mass ratio and structural damping factor on cylinder in-line VIV are discussed.
