Large Eddy Simulation of a Counterflow Configuration
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001AbstractThe aim of the present work is to extend the possibilities of predicting turbulent activity and mixing in counterflow burners. Such burners are well suited for the calibration and validation of combustion models. Because of their geometry, they allow simulations to be performed in only one dimension of space.

Large Eddy Simulation of a Backdraft with Watermist
Journal of Applied Fire Science, 2005A subgrid scale (SGS) model for partially premixed combustion has been implemented and applied to simulate the backdraft phenomena and its mitigation by watermist. The model is based on the coupling of independent approaches for non-premixed and premixed turbulent combustion.

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 ...
