Characterization of impinging jet flames

Combustion and Flame, 1999
This brief communication reports five basic combustion modes of impinging jet flames that have been identified experimentally. The apparatus involves a burner and a water-cooled plate which is positioned directly above the burner nozzle ...

Flame Curvature Statistics in Axisymmetric Turbulent Jet Flames

Combustion Science and Technology, 1995
ABSTRACT Flame curvature in axisymmetric turbulent jet flames are obtained experimentally for u'/S L from 0.8–1.5. The measurements indicate that the flame curvature statistics exhibit a substantial change as a function of the axial location in turbulent jet flames primarily due to the evolution of flame wrinkle structures.

Mechanism of Flame Stabilization in Turbulent, Lifted-Jet Flames

Combustion and Flame, 1998
Particle image velocimetry was used to study the velocity field in the stabilization region of lifted, turbulent CH 4 -jet flames over a range of Reynolds numbers from 7000 to 19,500. Measured velocities at the flame base are considerably below the turbulent flame speeds derived from previous studies and show a dependence on the Reynolds number.

Turbulent hydrocarbon jet flames

Progress in Energy and Combustion Science, 1982
Abstract To consider turbulent hydrocarbon jet flames as an ensemble of wrinkled laminar flames gives useful information about details of the combustion process by studying reactive diffusive interfaces. Combined with the conserved scalar approach, non-premixed turbulent jet flames can be computed with satisfactory accuracy.

Diffusion in laminar flame jets

Symposium on Combustion and Flame, and Explosion Phenomena, 1948
Summary The lengths and concentration patterns offlames from circular nozzles burning in free air have been determined over a wide range of velocities with several nozzle diameters and for various gases and primary air-gas ratios. As the nozzle velocity is increased from zero the flame, burning under conditions of diffusional mixing with air ...

Measurement of the Conductivity of a Jet Flame

Journal of Applied Physics, 1954
A method for the measurement of the complex conductivity of a rocket exhaust flame is described. Typical results are shown for an acid-aniline rocket motor and a frequency of 200 mc/sec. The importance of sodium impurities is pointed out and illustrated experimentally.

Stability of laminar-jet flames

Symposium (International) on Combustion, 1965
A self-excited flame oscillation of low frequency appears often, when laminar fuel jets burn in open air. The flame oscillation is axially symmetrical and has no connection with the size of combustion chambers and the length of fuel pipes. The present paper reports the results of the study of this phenomenon on the basis of the hypothesis that the ...

Flame extinction of oxy-syngas nonpremixed jet flames

2014
Interest in carbon capture relevant to syngas based oxy-fuel combustion has inspired an extension of the high-resolution direct numerical simulation (DNS) to investigate the comprehensive nature of oxy-syngas combustion. The current research was motivated by two observations: (1) the local flame extinction of CO2-diluted oxy-syngas combustion has not ...
