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:

Combining LES of combustion chamber and an actuator disk theory to predict combustion noise in a helicopter engine
TL;DR: In this paper, a method to predict combustion noise in real aero-engines using large eddy simulations (LES) of the combustion chamber coupled with an analytical approach to model the acoustic transmission of acoustic and entropy noise through the turbine stages is described.

Survey of Turbulent Combustion Models for Large-Eddy Simulations of Propulsive Flowfields
Richard S. Miller,Justin Foster +1 more
TL;DR: A general review of turbulent combustion modeling closures applicable to large eddy simulations (LES) is provided in this article, where the focus is on "regime-independent" models able to provide turbulent combustion closures ranging from purely premixed to purely non-premixed and all regimes between these two limits.

LES of knocking in engines using dual heat transfer and two-step reduced schemes
TL;DR: In this article, a Conjugate Heat Transfer (CHT) technique is implemented to compute the flow within the engine over successive cycles with LES together with the temperature field within the cylinder head walls and the valves and a reduced two-step scheme is used to predict both propagating premixed flames as well as autoignition times over a wide range of equivalence ratios, pressures and temperatures.

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.
