Large-eddy simulation of turbulent channel flow using the explicit algebraic subgrid-scale model 2015 (English)In: Proceedings - 15th European Turbulence Conference, ETC 2015, TU Delft , 2015Conference paper, Published paper (Refereed)

Abstract [en]

Large-eddy simulation (LES) of turbulent channel flow are performed with a new subgrid-scale (SGS) stress model. The simulations show that with this model we can well predict turbulent wall flows at coarse resolutions and moderately high Reynolds numbers. The commonly used dynamic Smagorinsky model fails at coarser resolutions.
