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:

Nonlinear mode transition mechanisms of a self-excited Jet A-1 spray flame
TL;DR: In this paper, a non-premixed Jet A-1 spray flame yields an intermediate-amplitude, quasi-periodic L1 mode oscillation at 50 Hz for a low pilot equivalence ratio, and the frequency gradually increases with increasing fuel flow rates.

A reduced chemical kinetic reaction mechanism for kerosene-air combustion
TL;DR: In this article, a reduced chemical reaction mechanism for kerosene-air combustion is presented, which consists of 30 species and 77 irreversible reactions and is developed to accurate reproduce key flame parameters yet being small enough to be used in finite rate Large Eddy simulations (LES), Direct Numerical Simulations (DNS) and in Reynolds Average Navier-Stokes (RANS) simulations.

Structure and Dynamics of Premixed Swirl Flames at Elevated Power Density
TL;DR: In this article, the effect of increased thermal power density on the structure and dynamics of premixed swirl flames was studied under two flame conditions: one stable, and one with self-excited thermoacoustic oscillations.

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.
