一般注記The Smagorinsky model has been commonly used in large eddy simulation (LES) of turbulent flow. Although LES computations or a variety of flows using this model have yielded acceptable results, it was necessary to incorporate several modifications into the model: a)the model constant was optimized in different flows, b)the damping function was used to account for near-wall effects. These modifications were generally ad hoc. Besides, a poor correlation of Reynolds stress model value with the direct numerical simulation (DNS) exact value was reported. The resented paper's major objective is to address these issues and propose a new model which mitigates previous model's drawbacks by determining the proper energy scale in the subgrid scale eddy viscosity coefficient correlating with the channel flow DNS data.
