Abstract

In order to weaken the vibration response of the cylinder, the self-issuing jet method based on an internal pipe is investigated. The ocean current is modeled by Reynolds Average Navier-Stokes (RANS) method and the Shear Stress Transport (SST) k-ω transient model in order to fit the actual engineering. The motion is transformed into a mass-spring-damped oscillator model, and it will be solved by the Newmark-β method. A two-way fluid-structure interaction (FSI) numerical simulation channel is established by using embedded user-defined functions. The numerical method is demonstrated with relevant experimental results. It is found that the scheme to increase the velocity of the jet by reducing the outlet width is feasible. The self-issuing jet significantly reduces the amplitude ratio, and the amplitude ratio is reduced by 92.70% in Desynchronization region. Meanwhile, the self-issuing jet decreases the locking region of vortex resonance.
