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:

An extended flamelet-based presumed probability density function for predicting mean concentrations of various species in premixed turbulent flames
TL;DR: In this paper, the results quantitatively validate the flamelet approach for the mean mole fractions of all species, including radicals, but only if the actual PDF P( c ) is adopted.
Journal ArticleDOI
On-the-fly reduced order modeling of passive and reactive species via time-dependent manifolds
TL;DR: In this paper, a low-rank decomposition of the species to three time-dependent components is proposed, and the evolution equations for the three components are obtained from optimality conditions of a variational principle.

Improvement of fuel oil spray combustion inside a 7 MW industrial furnace: A numerical study
TL;DR: In this paper, the authors present a numerical analysis of fuel oil spray combustion inside an industrial furnace, which is a 7 MW cylindrical furnace which supplies heat to an oil refinery.

TL;DR: In this paper, planar laser-induced fluorescence (PLIF) of formaldehyde (CH2O), hydroxyl (OH), and methylidyne (CH) acquired jointly with Rayleigh scattering are used to produce joint PDFs (scatter plots) of the former vs. the latter.

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.
