Computational Fluid Dynamics Study for Modeling Vortex Induced Vibrations Using High Fidelity Turbulence Models
Keyword(s):
Flow over smooth cylinder at very high Reynolds number, ReD = 2×106, is simulated using the unsteady Scale Adaptive Simulation (SAS) turbulence model. Flow structures and vortex shedding were accurately captured. Grid sensitivity study was performed to compare averaged drag coefficient for a conformal fine mesh as well as non-conformal coarse mesh. Predicted value of drag coefficient was within 8% of the experimental value and Strouhal number compared well with the experimental observations.
