Physics of Fluids A-Fluid Dynamics
How the optimal choice of the filter function in large eddy simulations is related to the spectrum of the turbulent flow is shown. A new formula for the subgrid residuals, which ensures that the exact and filtered flow have the same energy decay profile, is also derived.
