Abstract
Correct representation of the effects of the turbulence structure near solid boundaries is very important for successful large-eddy simulation (LES). In the present work, this wall modeling is done based on explicitly filtered equations of motion which have so-called commutation error terms near solid boundaries. These terms are ignored in conventional LES, but in the present work, these boundary terms are modeled using a dynamic procedure, making use of the scalesimilarity of the modeled terms. It is found, by applying the procedure in LES of a channel flow, that the modeling of the boundary terms does improve the prediction of the wall-bounded chennel flow. The method can be easily extended to LES of flows over rough and complex surface and can be very useful in various application
