Joint Temperature-Volume Fraction Statistics of Soot in Turbulent Non-Premixed Jet Flames of Ethylene and a JP-8 Surrogate.
TL;DR: In this article, a 3-line approach to simultaneous measurement of soot concentration (on the basis of laser extinction) and soot temperature was proposed, which relies on the presence of significant laser attenuation to yield accurate measurements.
Journal ArticleDOI
Temperature dependence of collisional broadening and shift for the Kr 4 p 6 S 01→5 p [3/2] 2 electronic transition
TL;DR: Comparison with existing literature on broadening parameters of NO, OH, and CO laser-induced fluorescence spectra reveal interesting contributions from non-dispersive interactions on the temperature exponent.
Journal ArticleDOI
Pressure scaling of the collisional broadening parameters of Kr 4p6S01→→5p[3/2]2 transition.
TL;DR: Pressure scaling of collisional broadening parameters of krypton (absorber) 4p6S01→→5p[3/2]2 transition centered at 107.3 nm in the presence of nitrogen N2 is investigated.

Mixture fraction measurement in turbulent non-premixed MILD jet flame using Rayleigh scattering
TL;DR: In this paper , a Rayleigh scattering-based approach is proposed to measure mixture fraction in a turbulent ethylene MILD combustion zone, where the net heat release is positive across the entire combustion domain.
Journal ArticleDOI
Quenching measurements of Kr 5p[3/2]2 ← ← 4p6 1S0 electronic transition using absorption spectra.
TL;DR: In this paper , the authors proposed a new approach for making direct quenching measurements at atmospheric conditions and using nanosecond lasers, which is demonstrated in a krypton-perturber system, and the 5p[32]2←←4p 6 1 S 0 two-photon electronic transition is accessed.

Soot particle measurements in diffusion flames
TL;DR: In this paper, the formation and growth of soot particles in a coannular diffusion flame have been studied using a laser extinction/scattering technique for particle size measurement, and the results reveal that the flame can be broadly divided into two regions.
Journal ArticleDOI
Laser Rayleigh scattering
TL;DR: In this paper, the spectral properties of Rayleigh scattering are discussed and a review of the new advances in flow field imaging that have been achieved using the new filter approaches is presented.

Studies of aromatic hydrocarbon formation mechanisms in flames: Progress towards closing the fuel gap
TL;DR: In this paper, two critical steps towards soot production in combustors are the decomposition of the fuel and the subsequent formation of aromatic hydrocarbons with one to three benzenoid rings.
