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:

The impact of swirling flow strength on lean-dome LDI pilot mixers’ operability and emissions
TL;DR: In this article, the clockwise vane angle of the outer air swirler is altered between 60° and 45° to represent strong and weak swirling flows, respectively, in a single-element methane-fueled combustor test rig.

The Effect of the Corner Recirculation Zone on Separated Stratified Swirling Flames and Combustion Instabilities
TL;DR: In this article, the effects of the corner recirculation zone (CRZ) on flame macrostructures and combustion instabilities in the Beihang Axial Swirler Independently Stratified (BASIS) burner were investigated.

Large scale motions of multiple limit-cycle high Reynolds number annular and toroidal rotor/stator cavities
TL;DR: In this article, a wall-resolved large eddy simulation is applied to two different rotor/stator cylindrical cavities and one annular cavity to investigate the influence of curvature and cavity aspect ratio on the large scale organization and flow stability at a fixed rotating disc Reynolds number.

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.
