Three-dimensional numerical simulations of the flow around rectangular cylinders with depth-to-height ratios (side ratio) of 3 and 6 at various Reynolds numbers were carried out using the Large eddy simulation (LES), which employs the Smagorinsky eddy-viscosity model, a type of subgrid scale (SGS) model. Computed results compared well with experimental ones. The irregular fluctuation of aerodynamic forces can be simulated. The time history of the lift force corresponded well to the variation of flow pattern.
