摘要
A refinement of the standard Smagorinsky model is proposed in order to take into account the inhomogeneities of the mean flow. First results concerning turbulent plane- channel flows and backward-facing step flows indicate that the model possesses a good predictive capability, essentially equivalent to the dynamic Smagorinsky model, but with a computational cost and a manageability comparable to the original Smagorinsky model.
