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 Role of CFD in Modern Jet Engine Combustor Design
TL;DR: In this paper, a revised flamelet formulation, FlaRe, is introduced to outline the general LES methodology for combustion modelling and then used for a range of test cases to demonstrate its capabilities for both laboratory burners and practical engine combustors.

Boundary-condition models of film-cooling holes for large-eddy simulation of turbine vanes
TL;DR: In this paper, the authors compared the performance of a spatially uniform injection with a model taking into account velocity and temperature spatial variations at the hole exit, and a non-turbulent injection with synthetic turbulence injection.

Assessment of the impact of subgrid-scale stress models and mesh resolution on the LES of a partially-premixed swirling flame
TL;DR: It was found that the use of advanced SGS models can improve the accuracy of the results significantly in both the highly turbulent region close to the burner and in the low-turbulence region further downstream.

Non-linear Interactions of Two Premixed Flames Explored by Large Eddy Simulation with External Acoustic Forcing
Xingsi Han,Aimee S. Morgans +1 more
TL;DR: In this article, the effect of the flame separation distance on both the flame dynamics and unsteady heat release responses is analyzed, and the results show that the interaction between two lean premixed flames is nonlinear.

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.
