Surface Flame Spread

2016
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 ...

Flame spread on aviation fuels

Fire Safety Journal, 1997
Abstract 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, 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°.

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

A numerical model for flame spread along combustible flat solid with charring material with experimental validation of ceiling flame spread and upward flame spread

Fire and Materials, 2007
AbstractThis paper gives a numerical model for flame spread along combustible flat solid with charring materials. The presented model consists of a one‐dimensional flame spread model coupled with a one‐dimensional pyrolysis model. The existing experimental data (the ceiling flame spread beneath medium density fibreboard) are used for comparison to ...

Downward flame spread over extruded polystyrene

Journal of Thermal Analysis and Calorimetry, 2014
An experimental study on the characteristics of downward flame spread of extruded polystyrene (XPS) is presented. The parameters investigated include average mass loss rate per unit of thickness ( $$ \dot{m}^{'} $$

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 ...

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 Through Wooden Dowels

2014
In practical applications, flammable materials are often arranged in arrays of discrete objects whose combustion properties may be different as that of a homogeneous material. In this study, the influence of spacing between arrays of wooden dowels on the rate of upward flame spread through arrays has been studied.

Theory of flame spread above solids

Acta Astronautica, 1974
A theory for flame spread above a solid fuel is presented. The special case is considered whereby the oxidation is an exothermic surface reaction. The spreading rate is predicted as a function of the thermochemical properties, fuel-bed thickness, and convective velocity. Also, the theory predicts temperature, mass fraction, and heat flux as a function
