Optimality of the dynamic procedure for large-eddy simulations [PDF]

open access: yesPhysics of Fluids, 2005
We present a database analysis to obtain a precise evaluation of the accuracy limitations associated with the popular dynamic eddy-viscosity model in large-eddy simulation. We consider decaying homogeneous isotropic turbulence at two different Reynolds numbers, i.e., Reλ=50 and 100. The large-eddy simulation errors associated with the dynamic model are
