TL;DR: In this paper, a chemical kinetic mechanism for C1 and C2 fuel combustion and PAH growth, previously validated for laminar premixed combustion, has now been modified and applied to opposed flow diffusion flames.
183 citations
TL;DR: In this article, the local soot volume fraction in a co-flowing, flickering CH 4 /air diffusion flame burning at atmospheric pressure was measured using tomographic reconstruction of extinction data obtained at 632.8 nm.

TL;DR: In this paper, the principal burning characteristics of a laminar flame comprise the fuel vapour pressure, the burning velocity, ignition delay times, Markstein numbers for strain rate and curvature, the stretch rates for the onset of flame instabilities and of flame extinction for different mixtures.

TL;DR: This novel approach to soot sizing exhibits several theoretical and technical advantages compared with the established combination of elastic scattering and LII, especially as it yields absolute sizes of primary particles without requiring calibration.
Abstract: The evaluation of the temporal decay of the laser-induced incandescence (LII) signal from soot particles is introduced as a technique to obtain two-dimensional distributions of particle sizes and is applied to a laminar diffusion flame. This novel approach to soot sizing exhibits several theoretical and technical advantages compared with the established combination of elastic scattering and LII, especially as it yields absolute sizes of primary particles without requiring calibration.

TL;DR: In this paper, the Lagrangian flamelet model was applied to a steady, turbulent CH 4 /H 2 /N 2 -air diffusion flame and the results were shown to be in reasonable agreement with experimental data for axial velocity, mixture fraction, species mass fraction, and temperature.
