A formalism for analyzing errors is developed in the context of finite difference approximations for the Navier-Stokes equations when the flow is fully turbulent. Analytical expressions for the power spectra of these errors are derived by exploiting the joint-normal approximation for turbulent velocity fields. These results are applied to large-eddy simulation of turbulence to obtain quantitative bounds on the magnitude of numerical errors.
