Nature, 1931
MASON and Wheeler,1 following the initial observation of Mallard and Le Chatelier, considered that when a gaseous explosive mixture is suitably ignited at the open end of a horizontal glass tube, the other end of which is closed, flame travels at a uniform speed for some distance.

The Mechanism of Flame Propagation
The Journal of Chemical Physics, 1948Recently Tanford and Pease have shown that in a number of carbon monoxide flames the burning velocity increases as the calculated equilibrium concentration of hydrogen atoms in the flame front increases. They point out that this would be so if the propagation of the flame were dependent on the diffusion of hydrogen atoms ahead of the flame. It is shown

Flame Propagation and Acoustics
Combustion, Explosion, and Shock Waves, 2019An intense effect of acoustic waves on the structure and shape of the burner flame was discovered by Rayleigh. The present paper deals with acoustic waves in the case of flame propagation in a tube. The flame emits acoustic waves generating the flow in the tube.

Physics of Fluids
NH3/H2 as a clean fuel exhibits significant application potential. Clarifying its flame evolution characteristics in closed spaces holds substantial value for mitigating explosion consequences under accident scenarios. This study systematically investigates the flame deformation and acceleration mechanisms of premixed NH3/H2/air explosions through ...

On flame propagation in vortices
Combustion and Flame, 1976A literature survey of the effects of flame propagation around a vortex ring is presented. The velocity of flame propagation around the vortex ring was observed to be much higher than that in a mixture at rest. The combustion intensity and stability and the flame configuration were discussed. 8 references (DDA)

Combustion and Flame, 1959
Abstract Previous work on steady state propagation of flat flames is reviewed and various mathematical techniques are contrasted. In the numerical evaluation of the velocity of uniform propagation of flames, the effects of varying parameters, heat loss and chain reactions are considered, leading to analysis of stability of propagation.

Combustion and Flame, 1983
Abstract A simple heat balance has been used to analyze conditions for flame propagation in ducts. A heat flow parameter, coupled with the critical heat flux for ignition, has been used to define the ignition and extent of flame propagation for duct lining materials.

On the propagation of turbulent flames
Combustion and Flame, 1969Abstract Richardson's rigorous definition of the turbulent burning velocity is restated for a one-dimensional turbulent approach flow and an average flame orientation perpendicular to the flow direction. This definition is then used to discuss the transient behaviour of flames in a turbulent environment.

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.
