Analysis of Numerical Errors in Large Eddy Simulation
SIAM Journal on Numerical Analysis, 2002The numerical errors in large eddy simulation are studied analytically assming some time regularity of the solution of Navier-Stokes equations. First, a finite element formulation for LES method using Smagorinsky model is presented together with stability analysis.

At high Reynolds number the fluid velocity is exponentially sensitive to perturbations of the problem data. This sensitivity, however, is not uniform. The large structures (large eddies) evolve deterministically and are thus not sensitive [BFG02]. The small eddies are sensitive because they have a random character.

Let us briefly reexamine the spatial scales present in turbulent flows before discussing how large-eddy simulation can be formulated. Consider the turbulent energy spectra for various turbulent flows across a wide range of Reynolds numbers. Shown in Fig. 8.1 are the energy spectra for various three-dimensional turbulent flows non-dimensionalized by the

Abstract The large-eddy-simulation technique is introduced. The mathematical formulation is presented, and several examples are discussed. Some issues related to the resolution of the wall layer are reviewed. Challenges and possible future developments are addressed.

As already stressed in the previous chapters, there is a priori no difficulty in envisaging a numerical solution of the unstationary Navier Stokes equations for rotational flows: the various operators are represented by discrete systems relating the values taken by the velocity or vorticity components, pressure, density, temperature, etc...

Introduction In large-eddy simulation (LES), the larger three-dimensional unsteady turbulent motions are directly represented, whereas the effects of the smallerscale motions are modelled. In computational expense, LES lies between Reynolds-stress models and DNS, and it is motivated by the limitations of each of these approaches.
