In practical applications high Reynolds numbers flow fields are requested, and the direct simulation cannot be achieved. In the early period of the numerical simulation of the Navier-Stokes equations turbulence models, based on Reynolds averages, were widely used. These one-point closures turbulence models, as was shown in the 1969 Stanford conference,

Large-Eddy Simulation: How Large is Large Enough?
Journal of the Atmospheric Sciences, 2004The length scale evolution of various quantities in a clear convective boundary layer (CBL), a stratocumulustopped boundary layer, and three radiatively cooled (‘‘smoke cloud’’) convective boundary layers are studied by means of large-eddy simulations on a large horizontal domain (25.6 3 25.6 km2).

In this work, we use large eddy simulation (LES) to study the influence of grid and subgrid model on the lift and drag force predictions of a fixed cylinder undergoing streamwise sinusoidal oscillations in a steady flow, resulting in a varying Reynolds number, Re, within the range 405 ≤ Re ≤ 2482.

Over a decade ago, the author (Ferziger, 1983) wrote a review of the then state-of-the-art in direct numerical simulation (DNS) and large eddy simulation (LES). Shortly thereafter, a second review was written by Rogallo and Moin (1984). In those relatively early days of turbulent flow simulation, it was possible to write comprehensive reviews of what ...

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.
