Counterflow diffusion flames

Progress in Energy and Combustion Science, 1982
Abstract Laminar counterflow diffusion flames are generally referred to as the pure diffusion flame. This paper reviews experimental studies of these counterflow diffusion flames and presents a detailed summary of our present understanding of them.

Counterflow diffusion flame with polydisperse sprays

Proceedings of the Combustion Institute, 2002
An experimental study was performed on counterflow diffusion flames, in which polydisperse n-heptane sprays carried by a nitrogen stream from the lower duct, burn in oxidizer streams from the upper duct. The droplet-size distributions were varied with the nitrogen flow rate for atomization.

Characteristics of propagating tribrachial flames in counterflow

KSME International Journal, 2002
The effect of fuel concentration gradient on the propagation characteristics of tribrachial (or triple) flames has been investigated experimentally in both two-dimensional and axisymmetric counterflows. The gradient at the stoichiometric location was controlled by the equivalence ratios at the two nozzles; one of which is maintained rich, while the ...

Structure of Counterflow Diffusion Flame of Ethanol

Combustion Science and Technology, 1975
Abstract The opposed jet assembly has been adapted for stabilizing a counter flow diffusion flame of ethanol. Data on the thermo-aerodynamic structure of the flame, obtained with the help of interferometric and particle track techniques, have been presented and analysed to yield the heat release rate.

Flame-Acoustic Interactions in a Counterflow Field

42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004
The formulation of counterflow, quasi onedimensional, unsteady, compressible conservation equations are presented, together with the decomposition of pressure into mean pressure along the axis of symmetry, unsteady or acoustic (in axial direction) and radial components.

Combustion of Kerosene in Counterflow Diffusion Flames

Journal of Propulsion and Power, 2001
Numerical modeling has become an essential tool in combustion research as a means of predicting combustion performance and pollutant formation, e.g., NO x and soot. In many combustion models the combustion of a commercial fuel such as kerosene has been represented by single-step empirical expressions. To predict kinetically controlled phenomena, a more

Influence of Vorticity on Counterflow Diffusion Flames

Combustion Science and Technology, 1987
Abstract The extinction characteristics of diffusion flames of methane and butane in counterflow jets under opposing rigid-body rotation are investigated. It is found that the critical volumetric concentration of fuels in nitrogen corresponding to flame extinction decrease to a minimum value and increase thereafter as the jet angular velocity increases.

The structure of inhibited counterflowing nonpremixed flames

Combustion and Flame, 1994
Abstract Numerical simulations of the structure of laminar counterflow methane-air nonpremixed flames with chemical (chloromethane) and inert (nitrogen) agents added to the oxidizer stream were performed using a previously developed computer code. The computations were substantiated by measurements of the temperature and velocity fields.

NO formation in counterflow partially premixed flames

Combustion and Flame, 2007
An experimental and computational study of NO formation in low-strain-rate partially premixed methane counterflow flames is reported. For progressive fuel-side partial premixing the peak NO concentration increased and the NO distribution along the stagnation streamline broadened.

Flame speeds and stretch effects in counterflow aluminum flames

2015
The characterization of flame propagation of reactive particles in gas suspension has been done either indirectly, such as from pressure traces in constant-volume combustion bombs, or with more traditional techniques such as flame tubes and Bunsen burners.
