RESUMO
We present wall-resolved, large-eddy simulation (LES) of flow over a circular cylinder up to ReD = 105, based on the cylinder diameter D, in the subcritical regime. The numerical method is a fully centered-finite-difference scheme on a standard curvilinear O-grid. The stretched-vortex sub-grid scale model is used in the whole domain, including regions of large-scale separated flow. Both secondand fourth-order accurate schemes are used separately, and results, specifically the skin-friction coefficient along the cylinder surface and its variation with ReD, are compared with literature data.
