Examination of Parameters Affecting Large-Eddy Simulations of Flow Past a Square Cylinder.

A study which examined the flow over a square cylinder with emphasis on the numerical uncertainties arising from truncation of the spanwise extent and spatial resolution of spanwise periodic flows using large-eddy simulation (LES) is presented. Topics covered include examination of several domain widths, performing implicit LES over a rectangular cylinder, boundary conditions and numerical sensitivities to mesh size.
