Edge-Flames and Their Stability
Combustion Science and Technology, 1996Flame sheets that arise in non-premixed combustion often have edges. The leading edge of a flame spreading over a fuel-bed, solid or liquid, is one example. The edge of a hemi-spherical candle flame in microgravity is another. We construct a one-dimensional model which contains some of the essential physics of these edge-flames, and use this model to ...

FLAME STABILITY WITH ELLIPTICAL NOZZLESIN A CROSSFLOW
Combustion Science and Technology, 2004A subscaled flaring system was set up to investigate the effects of elliptical nozzles on flame stabilities of flares in a crossflow for a range of operating conditions. The work presents the experimental results of natural gas flames issuing from circular and different aspect ratios (major/minor axis) elliptical nozzles with discharge areas of 16.4 ...

Acceleration Effects on the Stability of Flame Propagation
SIAM Journal on Applied Mathematics, 1979We consider the effect of acceleration on the diffusional thermal instability of a plane flame front in a premixed gaseous mixture. We recall that the diffusional thermal instability occurs if the Lewis number L of the mixture is less than a critical value $L_0 $.

Experimental studies of flame stability limits of biogas flame
Energy Conversion and Management, 2012Abstract Flame stability of premixed biogas flame for Reference Test Burner (RTB) was investigated. In this study, six kinds of test gases were used to simulate biogas in which CO2 volume fraction varied from 30% to 45%. A series of experiments were conducted on two RTBs with different port diameters and at different outlet unburned mixture ...

Stability of the Porous Plug Burner Flame
SIAM Journal on Applied Mathematics, 1983Summary: We examine the linear stability of a premixed flame attached to a porous plug burner, using activation energy asymptotics. A dispersion relation is obtained which defines the stability boundaries in the wave-, Lewis- number plane, and the movement of these boundaries is followed as the mass flux is reduced below the adiabatic value and the ...

Mechanism of Flame Stabilization in Turbulent, Lifted-Jet Flames
Combustion and Flame, 1998Particle 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.

Combustion Waves and Flame Stability in Nanocomposites
ACS NanoCombustion in nanocomposites involves intricate coupling between chemical reactions and transport phenomena across multiple scales and phases, complicating the development of unified theories. In this study, we present a theoretical and experimental framework that can serve as the foundation for a unified theory of combustion wave dynamics and ...

Radiation effects on flame stabilization on flat flame burners
Combustion and Flame, 2012Abstract This study investigates the impact of radiative heat transfer on the behavior of flat flame burners within the framework of a simplified one-dimensional model. Flat flame burners stabilize planar premixed flames downstream of a porous plug.
