Laser-induced-fluorescence detection of nitric oxide in high-pressure flames with A-X(0, 2) excitation.
TL;DR: This work discusses the advantages of the A-X(0, 2) system (excited at 247.95 nm) based on measurements in laminar premixed methane/air flames at 1-40 bars and investigates the properties of a detection scheme for which excitation in the nitric oxide A- X(0- 2) band was used.
Journal ArticleDOI
Phase-locked two-line OH planar laser-induced fluorescence thermometry in a pulsating gas turbine model combustor at atmospheric pressure
TL;DR: Two-line OH planar laser-induced fluorescence (PLIF) thermometry was applied to a swirling CH4/air flame in a gas turbine (GT) model combustor at atmospheric pressure, which exhibited self-excited combustion instability.
Journal ArticleDOI
Quantification of NO A-X (0, 2) laser-induced fluorescence: investigation of calibration and collisional influences in high-pressure flames.
TL;DR: A calibration method that is applicable in technical combustion systems based on addition of NO to the burning flame is investigated for various air/fuel ratios and pressures and yields information about the influence of NO reburn processes.

Thermal grating and broadband degenerate four-wave mixing spectroscopy of OH in high-pressure flames
H. Latzel,Andreas Dreizler,Thomas Dreier,Johannes Heinze,M. Dillmann,W. Stricker,G. M. Lloyd,Paul Ewart +7 more
TL;DR: In this paper, the X2Π(0, 0,0) band of the DFWM was studied in premixed methane/air flames using a cw Ar+ laser probe.
Journal ArticleDOI
PLIF Thermometry Based on Measurements of Absolute Concentrations of the OH Radical
Johannes Heinze,Ulrich Meier,Thomas Behrendt,Chris Willert,Klaus Peter Geigle,Oliver Lammel,Rainer Lückerath +6 more
TL;DR: In this paper, a method for measurements of planar temperature distributions based on planar laser-induced fluorescence (PLIF) of the OH radiacal is described, which was developed specifically for the application in lean combustion systems, where OH equilibrium concentrations are largely independent on equivalence ratio and a function of temperature only.
