Laser-induced fluorescence of NCN in low and atmospheric pressure flames.
نویسندگان
چکیده
The cyanonitrene radical, NCN, is detected by laser-induced fluorescence in laminar, adiabatic, flat phi=1.3 methane-air flames at 200 hPa and atmospheric pressure. Laser excitation of the A approximately 3Piu(020)-X approximately 3Sigmag-(000) band at 317 nm allows off-resonant fluorescence to be detected at 326 nm. Excitation and dispersed fluorescence spectra are presented, as well as profiles of NCN and CH versus height above burner.

Calibration of laser induced fluorescence of the OH radical by cavity ringdown spectroscopy in premixed atmospheric pressure flames
Cavity ringdown spectroscopy (CRDS) of the hydroxyl radical (OH) has been explored in a laminar methane-air flame at atmospheric pressure over a range of equivalence ratio. Laser induced fluorescence of OH calibrated by CRDS in a lean flame compares well to PREMIX calculations using GRI-Mech 3.0. CRDS is a highly sensitive path-integrated diagnostic technique that can yield absolute absorber nu...
متن کاملLaser-induced-fluorescence detection of nitric oxide in high-pressure flames with A-X(0, 2) excitation.
Laser-induced fluorescence techniques have been used successfully for quantitative two-dimensional measurements of nitric oxide. The commonly applied D-X(0, 1) or A-X(0, 0) schemes are restricted to atmospheric-pressure flames and engines driven with gaseous fuels because of strong attenuation of the exciting laser beam by combustion intermediates. The properties of a detection scheme for which...
متن کاملSimultaneous planar laser-induced incandescence, OH planar laser-induced fluorescence, and droplet Mie scattering in swirl-stabilized spray flames.
Simultaneous planar laser-induced incandescence, hydroxyl radical planar laser-induced fluorescence, and droplet Mie scattering are used to study the instantaneous flame structure and soot formation process in an atmospheric pressure, swirl-stabilized, liquid-fueled, model gas-turbine combustor. Optimal excitation and detection schemes to maximize single-shot signals and avoid interferences fro...
متن کاملMeasurements of the indium hyperfine structure in an atmospheric-pressure flame by use of diode-laser-induced fluorescence.
We report on what we believe is the first demonstration of laser-induced fluorescence (LIF) in flames by use of diode lasers. Indium atoms seeded into an atmospheric-pressure flame at trace concentrations are excited by a blue GaN laser operating near 410 nm. The laser is mounted in an external-cavity configuration, and the hyperfine spectrum of the 5(2)P1/2 --> 6(2)S1/2 transition is captured ...
متن کاملCarbon dioxide UV laser-induced fluorescence in high-pressure flames
Laser-induced fluorescence (LIF) of carbon dioxide is investigated with excitation between 215 and 255 nm with spectrally resolved detection in 5–40 bar premixed CH4/O2/Ar and CH4/air flat-flames at fuel/air ratios between 0.8 and 1.9. The LIF signal consists of a broad (200–450 nm) continuum with a faint superimposed structure, and this signal is absent in similar H2/O2/Ar flames. There is str...
