Large-eddy simulations (LES) of turbulent flow around a square cylinder at Reynolds number of 2.2×104 are conducted. The subgrid-scale (SGS) models used here are the standard Smagorinsky model and a dynamic mixed SGS model. Simulation results indicate that the spanwise flow structure behind the cylinder is highly influenced by the spanwise mesh resolution and that the artificial dissipative effects of upwind schemes cannot be ignored even in the case of higher order upwind schemes.
