Abstract

A numerical study of vortex-induced vibration (VIV) of two circular cylinders of different diameters in steady flow is carried out. The Reynolds-averaged Navier-Stokes equations are solved using a finite element method (FEM) with a k-ω turbulence closure. The numerical model is firstly validated against VIV of a single circular cylinder in steady flow. Then this model is employed to simulate the flow around two circular cylinders which are mounted elastically. The response amplitude, vibration frequency of the two cylinders and vortex shedding modes are analyzed. It's found that the fluid flow fields and the response behavior are more complex than those of an isolated cylinder. The gap distance and arrangement of the two cylinders affects the VIV significantly.
