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:

Verification and Validation of a Low-Mach-Number Large-Eddy Simulation Code against Manufactured Solutions and Experimental Results
TL;DR: The results show that MMS is a promising tool for code verification and that the low-Mach-number LES code can accurately predict the non-reacting and reacting turbulent flows.

Evaluations of SGS Combustion, Scalar Flux and Stress Models in a Turbulent Jet Premixed Flame
Katsuhiro Hiraoka,Yoshitsugu Naka,Masayasu Shimura,Yuki Minamoto,Naoya Fukushima,Mamoru Tanahashi,Toshio Miyauchi +6 more
TL;DR: In this paper, a fractal dynamic SGS combustion model and a scale self-recognition mixed (SSRM) SGS stress model are evaluated along with other models in a priori and a posteriori manner using DNS data of a hydrogen-air turbulent plane jet premixed flame.
Numerical analysis of dynamics and stability in lean-burn gaseous flames for heavy duty gas turbines
TL;DR: In this article, both linear and nonlinear flame modelling can be used, making use of the so-called Flame Transfer Function (FTF) and Flame Describing Function (FDF) to predict whether a thermo-acoustic system is stable (without oscillations) or unstable (increasing oscillations).

Modelling of methane and hydrogen enriched methane flames in industrial gas turbine burners
TL;DR: In this paper, the authors explored the use of scale resolving turbulence models combined with flamelet based combustion models using both methane and hydrogen enriched methane for predicting the change in flame shape and location when introducing hydrogen enrichment.

Premixed flames subjected to extreme levels of turbulence part II: Surface characteristics and scalar dissipation rates
TL;DR: In this paper , the impact of turbulence on flame surface characteristics and scalar dissipation rates was assessed via the application of planar Rayleigh scattering (PRS) images with an accuracy that is conservatively estimated to be within ∼ 3%.

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.
