M. Sichel initiated the discussion by observing that at least in gases, steady one-dimensional detonations are seldom observed. Invariably, real detonations have a cellular structure.

The Structure and Stability of Flame Balls: A Near-Equidiffusional Flame Analysis
SIAM Journal on Applied Mathematics, 1991The energy and species conservation equations are considered in spherical geometry with Arrhenius kinetics. The model is thermal-diffusional (i.e. no fluid mechanical effects are considered). Asymptotic analysis is carried out and stability analysis of the two solutions demonstrated is carried out.

Propagating Flames and their Stability
1984Viewed on a hydrodynamical scale, a flame may be considered as a surface of discontinuity, separating burned from unburned gas. Unlike earlier treatments, which ignored the flame structure, the present study accounts for the interaction of the fluid flow with the transport processes and chemical reactions occurring inside the thin flame zone.

Monitoring Oxy-Coal Flame Stability
2018 IEEE 27th International Symposium on Industrial Electronics (ISIE), 2018This paper presents a novel approach to monitoring the stability of oxy-coal flames. Oxy-coal combustion has the potential to generate high concentrations of carbon dioxide in the exhaust gas stream. This could increase the efficiency of the removal of carbon dioxide emissions from a coal fired utility boiler.

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 $.

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 ...

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 ...
