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:

Inclusion of flame stretch and heat loss in LES combustion model
TL;DR: In this paper, the TECFLAM swirl burner is simulated with Large Eddy Simulation (LES) using ANSYS Fluent and the turbulent combustion is modelled using the Flamelet Generated Manifold (FGM) formulation both with an Extended Turbulent Flame Closure (ETFC) model to introduce the stretch and heat loss effects on the flame and with the standard Zimont’sTurbulent flame closure.

High-resolution numerical schemes for compressible flows and compressible two-phase flows
TL;DR: Several high-resolution numerical schemes based on the Constrained Interpolation Profile Conservative Semi-Lagrangian (CIP-CSL), Essentially Non-Oscillatory (ENO), Weighted ENO, Weighted WENO, Boundary Variation Diminishing (BVD), and Tangent of Hyperbola for INterface Capturing (THINC) schemes have been proposed for compressible flows and compressible two-phase flows.

Large eddy simulation of premixed combustion using flamelets
TL;DR: In this paper, two models are identified, one based on an algebraic expression for the reaction rate of a progress variable and the assumption of fast chemistry, the other based on a database of unstrained flamelets in which reaction rates are stored and parametrised using a progress variables and its SGS variance, and their potentials are shown for a wide range of premixed combustion conditions of practical interest.

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.
