Upwind schemes are evaluated with respect to their spectral accuracy in solving advection–diffusion equations. Their connection to large eddy simulations (LES) and direct numerical simulations is explored. Some broad guidelines are set forth to select an appropriate scheme for simulating a Navier–Stokes equation with or without a subgrid‐scale model. Copyright © 1999 John Wiley & Sons, Ltd.
