摘要:Vortex-induced vibration ( VIV) is a typical problem in ocean engineering , and the inhibiting effect on vortex-induced variable-section cylinder is discussed in this paper.The vibration of the riser was simplified into a mass-spring-damping system.The finite volume method was combined with SST k-ωturbulence model to calculate the VIV of the cylinder, and the vibration response of the cylinder generated by VIV was solved by the fourth order Runge-Kutta method.On the basis of two-dimensional cylinder problems such as the vibration amplitude , vibration track, form of take-off vortex, and verification of the analysis method , a VIV of three-dimensional variable section cylinder was simulated and analyzed.The results show that the amplitude of the variable section cylinder is lower than that of the cylinder , and the break of the section will cause separation of the vortex.This provides a new evi-dence for research on the inhibiting effect and model experiments of VIV.
