Grid Filter Modeling for Large-Eddy Simulation

An interpretation to the use of deconvolution models when used in implicitly filtered large-eddy simulations as a way to approximate the projective grid filter is given. Consequently, a new category of subgrid models, the grid filter models, is defined. This approach gives a theoretical justification to the use of deconvolution models without explicit filtering of the solution and explains how the use of such models can be effective in this context.
