摘要：
To study the flow characteristics around two-degree-of-freedom piggyback pipelines, this work uses the high-resolution immersed boundary method in simulating the vortex-induced vibration characteristics of a two-degree-of-freedom piggyback pipeline with different arrangements. The effects of mass ratio, spacing-to-diameter ratio, gap-to-diameter ratio, and position angle on the vibration performance and hydrodynamic characteristics of the low Reynolds number flow of the piggyback pipeline are discussed in detail. Simulation results show that the maximum amplitude of the vortex-induced vibration of the pipeline gradually decreases with an increase in mass ratio and spacing-to-diameter ratio. Meanwhile, the lock-in region also becomes relatively small. The angle of the piggyback pipeline and main pipeline exert some effects on vortex-induced vibration suppression. The vortex-induced vibration suppression is strong when the two pipelines are in tandem. In addition, the effect of downstream vibration on the amplitude and frequency of cross-flow vibration increases at a low mass ratio but decreases at a high mass ratio.
