AbstractWe study the effect of homogenization on flame propagation in periodic excitable media when the width of the flame is much smaller than the characteristic size of the heterogeneities. © 2005 Wiley Periodicals, Inc.

High-speed visualization of flame propagation in explosions
Journal of Visualization, 2001Flow visualization data is presented to describe the structure of flames propagating in methane-air explosions in semi-confined enclosures. The role of turbulence is well established as a mechanism for increasing burning velocity by fragmenting the flame front and increasing the surface area of flames propagating in explosions.

Diffusion-Controlled Cool Flame Propagation Speeds
44th AIAA Aerospace Sciences Meeting and Exhibit, 2006Cool flames in an equimolar propane-oxygen premixture have been studied at reduced gravity in a closed, unstirred, static, spherical reactor. Acquired visual records were then analyzed and used to determine the cool flame propagation speeds for different vessel temperatures and initial reactant pressures.

Correction of edge-flame propagation speed in a counterflow, annular slot burner [PDF]
Combustion and Flame, 2015 To characterize the propagation modes of flames, flame propagation speed must be accurately calculated. The impact of propagating edge-flames on the flow fields of unburned gases is limited experimentally.

High-speed interferometer system for flame propagation studies
Optics & Laser Technology, 1971Abstract A system comprising a laser interferometer and two high speed cine-cameras has been developed in order to photograph simultaneously in colour the spread of flame among polythene particles suspended in air and the corresponding interferograms of the changes in refractive index.

Effects of flame propagation speed and chamber size on end-gas autoignition [PDF]
Proceedings of the Combustion Institute, 2017 End-gas autoignition has direct relevance to engine knock and thereby has been extensively studied. However, in the literature there are still some contradictions on how different factors affect end-gas autoignition and knock intensity.

The constant-volume propagating spherical flame method for laminar flame speed measurement
Science Bulletin, 2016Laminar flame speed is one of the most important intrinsic properties of a combustible mixture. Due to its importance, different methods have been developed to measure the laminar flame speed. This paper reviews the constant-volume propagating spherical flame method for laminar flame speed measurement.

Local flame propagation speeds along wrinkled, unsteady, stretched premixed flames
Symposium (International) on Combustion, 1998The local displacement speed was measured along a premixed flame that is wrinkled, unsteady, stretched, and freely propagating. The displacement speed is argued to be the most important and sensitive parameter that must be simulated correctly in numerical simulations of turbulent flames.

We consider the propagation speed of thin premixed flames disturbed by the fluid flow and suggest a new approach based on using the generalized curvilinear system of coordinates and tenser calculus. The suggested technique is shown to be more simple than the traditional technique used by Sivashinsky (1976), Matalon and Matkowsky (1982) and also in ...
