Abstract
Simulation results for two-dimensional and three-dimensional wakes of circular cylinders are compared at Re = 265, which is sufficiently high for the wake of a fixed cylinder to exhibit spatio-temporal chaos. Comparisons are made both for fixed cylinders and those in forced cross-flow oscillation. Assessments of the two-dimensionality of the three-dimensional wake flows are made on the basis of spanwise correlations of fluctuating forces and wake velocities, and also via Fourier analysis. Force coefficients from spanwise-averaged three-dimensional flows are compared with those for equivalent two-dimensional flows.
