Abstract

Vortex-induced vibrations of two mechanically coupled cylinders of different diameters in steady incompressible flow are studied. The diameter ratio of the cylinders is fixed at 0.1. Petrov-Galerkin finite element method is used to solve the two dimensional Reynolds-averaged Navier-Stokes equations equipped with SST k - Ï‰ turbulence model closure. The numerical model is evaluated against available experimental results. Following that, the effects of cylinders' gap and their angular orientation relative to the free stream on oscillation amplitude and force coefficient variation of the bundle are investigated. It is found that small changes in the arrangement of the cylinders can lead to considerable changes of oscillation amplitudes.
