چکیده

We report the use of a tunable ArF laser at 193.26 nm to record simultaneous single-laser-shot, planar images of molecular hydrogen and hot oxygen in a turbulent H(2)-air diffusion flame. Excitation spectra of fuel and oxidantrich flame zones confirm a partial overlap of the two-photon H(2) (6,0) Q(1) E, F ? X and single-photon O(2) (10,2) R(17) B ? X (Schumann-Runge) absorption bands. UV Rayleigh scattering images of flame structure and estimated detection limits for the H(2) two-photon imaging are also presented.

Mixture fraction imaging in turbulent non-premixed flames with two-photon LIF of krypton

The use of a noble gas as an inert tracer for mixing studies in combustion systems is investigated. Simultaneous two-photon laser-induced fluorescence (LIF) of krypton and Rayleigh scattering are used for imaging measurements of mixture fraction and temperature in turbulent non-premixed jet flames. The turbulent flames investigated in this study include a piloted CH4/air flame (Sandia flame D) ...

Reaction-rate, Mixture-fraction, and Temperature Imaging in Turbulent Methane/air Jet Flames

Instantaneous two-dimensional measurements of reaction rate, mixture fraction, and temperature are demonstrated in turbulent partially premixed methane/air jet flames. The forward reaction rate of the reaction CO OH ⇒ CO2 H is measured by simultaneous OH laser-induced fluorescence (LIF) and two-photon CO LIF. The product of the two LIF signals is shown to be proportional to the reaction rate. T...

High-Repetition-Rate Imaging of Atomic Oxygen In Flames

Two-photon laser-induced fluorescence (TPLIF) is a well-recognized approach for detecting atomic oxygen however, measurements to date have been restricted to a single point within a flow, flame, or plasma, due to the inherently high intensity requirements for the excitation laser. Furthermore, the high-intensity ultraviolet (UV) photons used for two-photon excitation process can photochemically...

Two-dimensional imaging of soot volume fraction and OH in turbulent jet diffusion flames spanning low to high mixing rates

Simultaneous planar measurements of laser-induced incandescence (LII) and Laser-Induced Fluorescence of OH radical were carried out in turbulent jet flames from a simple jet, precessing jet and bluff body burner firing natural gas. These flames span a wide range of global mixing rates and sooting characteristics, and are selected because measurements of total NOx emissions, radiant fraction and...

Quantification of NO A-X (0, 2) laser-induced fluorescence: investigation of calibration and collisional influences in high-pressure flames.

Laser-induced-fluorescence techniques have been used successfully for quantitative two-dimensional measurements of nitric oxide. NO A-X(0, 2) excitation at 248 nm recently found applications in internal-combustion engines. We assess the collisional processes that influence quantification of signal intensities in terms of saturation, rotational energy transfer, and line broadening, using laminar...
