The equations for LES are formally derived by low-pass filtering the NS equations with the effect of the small scales on the larger ones captured by a SGS model. However, it is known that the LES equations usually employed in practical applications are inconsistent with the filter operator when no explicit filter is used. Moreover, even for explicitly filtered LES, some inconsistencies remain in the wall-normal direction due to the constraining effect of the wall. A typically undesirable effect…

Sharp cutoff versus smooth filtering in large eddy simulation
The large eddy simulation (LES) equations of turbulent flows are formally derived by applying a low-pass filter to the Navier–Stokes equations. As a result the subgrid-scale (SGS) stress tensor
The effect of numerical errors and turbulence models in large-eddy simulations of channel flow, with and without explicit filtering
TLDR
It is found that for explicit filtering, increasing the reconstruction levels for the RSFS stress improves the mean velocity as well as the turbulence intensities, when compared to LES without explicit filtering.

Subgrid modeling for the scalar transport equation and for the incompressible Navier-Stokes equations is considered. It is shown that, for the case of scalar transport, a tensor diffusivity may be
