Large Eddy Simulations of gaseous flames in gas turbine combustion chambers
TLDR
In this article, two types of LES in complex geometry combustors and of specific interest for aeronautical gas turbine burners are reviewed: (1) laboratory-scale combustors, without compressor or turbine, in which advanced measurements are possible and (2) combustion chambers of existing engines operated in realistic operating conditions.About:

Large eddy simulations of turbulent combustion of kerosene-air in a dual swirl gas turbine model combustor at high pressures
TL;DR: In this article, large eddy simulations are conducted in a dual swirl gas turbine model combustor to analyze the effects of different fuel-air equivalence ratios and chamber pressures on swirling injection and turbulent combustion.

Non-Intrusive Uncertainty Quantification in the simulation of turbulent spray combustion using Polynomial Chaos Expansion: A case study
TL;DR: In this article, the authors present results from a comprehensive quantification of uncertainties from the specification of a spray boundary condition and numerical approximation errors and evaluate the total predictive uncertainty in the case considered.

Contributions of flame thickening and extinctions to a heat release rate marker of intensely turbulent premixed hydrogen-enriched methane-air flames
TL;DR: In this paper, the authors investigated the influence of reaction zone thickening and extinctions on a heat release rate marker of extremely turbulent hydrogen-enriched methane-air flames using simultaneous planar laser-induced fluorescence of formaldehyde molecule and hydroxyl radical as well as separate stereoscopic particle image velocimetry techniques.
Journal ArticleDOI
Anchoring mechanisms of a holder-stabilized premixed flame in a preheated mesoscale combustor
TL;DR: In this paper, a very lean-premixed, laminar methane-air flame is demonstrated, experimentally, to be stable in a mesoscale combustor with a flame holder.
Journal ArticleDOI
A DNS assessment of linear relations between filtered reaction rate, flame surface density, and scalar dissipation rate in a weakly turbulent premixed flame
TL;DR: In this article, the authors examined the relation between RANS expressions and local relations valid within weakly perturbed flamelets, and showed that the linear relation holds solely for the entire flamelet and may not hold within the filtered flamelet volume.

General circulation experiments with the primitive equations
TL;DR: In this article, an extended period numerical integration of a baroclinic primitive equation model has been made for the simulation and the study of the dynamics of the atmosphere's general circulation, and the solution corresponding to external gravitational propagation is filtered by requiring the vertically integrated divergence to vanish identically.

The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.
