Flame stabilization by plasma jets

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1971
The possibility of increasing flame reaction rates, stability and hence the throughput of chemical energy achievable by the addition of a small proportion of electrical power is stuided. The power is added to a subsidiary stream of different gases by a magnetically rotated plasma jet. Rates of rotation of the order 10 5

Flame and Soot Boundaries of Laminar Jet Diffusion Flames

AIAA Journal, 2002
The shapes (flame-sheet and luminous-flame boundaries) or steady weakly buoyant round hydrocarbon-fueled laminar-jet diffusion flames in still and coflowing air were studied both experimentally and theoretically. Flame-sheet shapes were measured from photographs using a CH optical filter to distinguish flame-sheet boundaries in the presence of blue CO2

Pilot Flame Effects on Gas Jet Flames in Crossflow

Journal of Propulsion and Power, 2002
Flame structure, which includes the radiation power and temperature profiles, soot concentration profiles, and pollutants emissions (NO, NO x , CO, and CO 2 ) of propane and propylene gas diffusion flames with and without ahydrogen pilot flame in crossflow is presented.

Turbulent swirling jet diffusion flames

AIAA Journal, 1969
The phenomenological boundary-layer equations describing the flowfield in a turbulent jet diffusion flame with swirl are solved in the von Mises plane. The expressions found are compared with experimental results for three jet flames with different degrees of swirl using semiempirical values of turbulent exchange coefficients in the flame. The combined

Jet flame attack on vessels

Journal of Loss Prevention in the Process Industries, 1994
Abstract This paper presents an overview of activities related to jet fires interacting with obstacles as carried out within the CEC-sponsored project JIVE. A modelling technique and experimental data related to the determination of heat transfer from jet fires to obstacles such as pipework and vessels are presented.

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 ...

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.
