Flame Propagation in Poiseuille Flow
39th Aerospace Sciences Meeting and Exhibit, 2001We describe flame propagation in a channel subject to a Poiseuille flow within the context of a thermo-diffusive model under (i) adiabatic conditions, and (ii) in the presence of conductive heat losses at the walls. The curved two-dimensional lfames examined may be either assisted or opposed by the flow.

Numerical Simulation of the Influence of Vent Conditions on Hydrogen Flame Propagation
Combustion Science and Technology, 2020In order to reduce the damage caused by a gas explosion in a ventilation duct, a Large Eddy Simulation (LES) model was used to simulate the hydrogen/air explosion process in the ventilation duct under different side vent.

Premixed Flame Propagation of Methane/Carbon Monoxide/Air in a Closed Tube with an Obstacle
Combustion Science and Technology, 2020To investigate the actual gas explosion and propagation laws in the roadway of an underground mine, experiments were conducted in a standard 19-L tube of rectangular section to provide a comprehensive understanding of the effects of carbon monoxide (CO ...

Abstract The premixed flame propagating through a vertical channel and subject to buoyancy effects is analyzed. In the limit of strong thermal expansion of the burned gas and small normal flame speed, assuming the channel to be wide enough, the problem transpires to be closely related to the classical Rayleigh-Taylor problem for a long bubble rising ...

The Physics of Fluids, 1962
An idealized theory of flame propagation is formulated to explain the effects of tube diameter, mixture composition, and direction of motion in a gravity field on the flame shape and ``speed of uniform motion'' of a flame front propagating through a stationary air-fuel mixture contained in a long tube. The effect of local flame curvature on flame speed

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.

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.
