Code Saturne® is a finite-volume, unstructured-grid code developed at Électricité De France (EDF), which solves the Reynolds-averaged Navier-Stokes equations for incompressible flows. The code has been extensively benchmarked for a variety of industrial applications. The solver has been extended at EDF to solve large-eddy simulation equations, and we found that the numerical methods used in the base RANS code are not directly applicable to LES. This paper uses Code Saturne to investigate the performance of several numerical schemes for LES of different academic and industrial flows. In particular, the conservation of global kinetic energy and robustness of several numerical schemes are compared and discussed. Finally, Code Saturne with non-dissipative numerical methods is validated for the swirling flow in a coaxial geometry corresponding to the experiments of Sommerfeld & Qiu (1991). Also, the role of the subgrid-scale (SGS) model is investigated through simulations without a SGS model (coarse DNS), with a constant Smagorinsky model and with a dynamic Smagorinsky model.
