A simplified method for determining flame spread

Fire Technology, 1967
The 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 spread on inclined surfaces

Fire Safety Journal, 1992
Abstract 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 Spreading From Baffles

Journal of Jet Propulsion, 1956
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 .

Flame height correlation and upward flame spread modelling

Fire and Materials, 2002
AbstractPrevious 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, 1995
AbstractThe 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

Precursor flame characteristics of flame spread over aviation fuel

Applied Thermal Engineering, 2017
Abstract Research on flame spreading over liquids is indispensable to make a fire risk assessment of large-sized pool fires in their incipient stages. This precursor flame that is a unique behavior for flame spread over hydrocarbon oils is still not exhaustively understood. A series of tests on flame spread over aviation fuel of RP-5 is well designed

Spread of a laminar diffusion flame

Symposium (International) on Combustion, 1969
A 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 spread and flame shape

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 ...

Analysis of upward flame spread

1992
Upward flame spread on wall linings is analyzed theoretically with special emphasis on the application of the models to predict whether the flame spread will be deceleratory or acceleratory. Much of the work is devoted to a revised application of the model by Saito et a..
