| Abstract: |
| Based on the Navier-Stokes equations, k-ω turbulent model, SUPG Finite Element method and Arbitrary Lagragian-Eulerian method, a numerical model is developed in this work to investigate the forced oscillation of circular cylinder in uniform flow. The 2S, 2P and P+S wake modes are simulated successfully in the wake region at Re=5000. The lift and drag coefficients are in good agreement with the available numerical and experimental data. The variations of fluid forces with the oscillation frequencies of circular cylinder at different non-dimensional amplitudes of 0.3, 0.4 and 0.5 at Re=10000 are also examined. The lock-in region is obtained and agrees well with the experimental data. It shows that the present two-dimensional model is able to predict the characteristics of VIV, but the three-dimensional viscous numerical model is necessary for the accurate numerical simulation. |
