A simplified method for determining flame spread
Fire Technology, 1967The author discusses a small-scale fire test, which he proposes be used to determine flame-spread ratings for plastics during the development stages. Data on certain cellulosic materials indicate good correlation with the 25-ft tunnel test.

Flame spreading from 0.5 to 2.25-inch V-gutter baffles in two-dimensional turbulent ducted flow was studied experimentally. Measurements of combust ion efficiency were made at distances of 10 to 43 inches downstream of the flame stabilizing baffle(s) in a 9 X 5-inch duct .

Surface flame spread is a process of a moving flame in the vicinity of a pyrolyzing region on the surface of a solid or liquid that acts as a fuel source. It is distinct from flame propagation in a premixed fuel and oxygen system in that the surface spread of flame occurs as a result of the heating of the surface due to the direct or remote heating by ...

Instability of Flame Spread in Microgravity
Heat Transfer: Volume 4, 1999Abstract Results from the first part of an experimental study of flame spread instability are presented. The instabilities were investigated in the NASA drop facilities because the particular instabilities being examined were most pronounced in microgravity, when the influences of buoyancy were minimized.

Flame spread on aviation fuels
Fire Safety Journal, 1997Abstract Flame spread rates and flame spread induction times have been measured for JP-5, JP-8 and mixtures of these fuels over the temperature range 10–90°C. The flame spread data were correlated on the basis of the initial liquid temperature relative to the closed cup flashpoint.

Flame spread on inclined surfaces
Fire Safety Journal, 1992Abstract Experiments have been carried out to investigate the effect of slope on the rate of upward spread of flame over a combustible solid. There is a clear difference between the mechanisms of spread for thin and thick fuels. With the latter, a change in mechanisms is found to occur at an inclination of 15–20°.

Flame height correlation and upward flame spread modelling
Fire and Materials, 2002AbstractPrevious work has demonstrated that flame height is one of the two most important parameters determining the rate of vertical flame spread on a wall. Flame spread models rely on empirical flame height correlations of the form Xf=KQ̇′n, but there have been no carefully controlled experiments designed to establish the validity of such ...

The role of flame flux in opposed‐flow flame spread
Fire and Materials, 1995AbstractThe flame spread process is driven by the net heat flux to the specimen surface, including the flux from the flame itself. This flame flux is important since it comprises a major part of the driving force causing flame fluxes were obtained. The values which are reported do not appear consistent and show more deviation among materials than would

Spread of a laminar diffusion flame
Symposium (International) on Combustion, 1969A theoretical description is presented for a laminar diffusion flame spreading against an air stream over a solid- or liquid-fuel bed. Both a thin sheet and a semi-infinite fuel bed are considered. The burning process is described as follows: The hot flame heats the unburned fuel bed, which subsequently vaporizes.

Fire Technology, 1968
In laboratory tests, the size of a flame front can significantly affect the rate of fire spread. The configuration factor of a given flame shape provides a method for relating flame fronts of various widths. The author discusses an analog system for determining the configuration factor of an irregularly shaped flame and the effects of flame width and ...
