Shear-improved Smagorinsky model for large-eddy simulation of wall-bounded turbulent flows

A shear-improved Smagorinsky model is introduced based on results concerning mean-shear effects in wall-bounded turbulence. The Smagorinsky eddy-viscosity is modified as v T =(C s δ) 2 (| S |—|〈 S 〉|): the magnitude of the mean shear |〈 S 〉|is subtracted from the magnitude of the instantaneous resol... View More
