Part I Ignition temperatures and flame spread rates
Fire Technology, 1969Part I of this two-part report deals with the effects of oxygen enrichment on ignition temperatures and flame spread rates of materials that might be found in hospital hyperbaric chambers. Part II will be carried in the November issue.

Effect of Environmental Variables on Flame Spread Rates in Microgravity
45th AIAA Aerospace Sciences Meeting and Exhibit, 2007This paper reports 2D CFD-based computer modeling of opposed flow flame spread over thick samples of polymethylmethacrylate (PMMA). Model predictions are compared with experimental data from normal-gravity experiments at multiple forced flow velocities and KC-135 parabolic flight microgravity experiments.

The combustion and flame spread behaviors of discrete fuels often depend on the distribution of the fuel arrays, including the fuel bed width and the spacing of the fuel arrays. In this study, scenarios with six different numbers of columns (n, 1–11 with

The fuel inclination and wind velocity play a significant role on the forward flame spread behavior. It deserves further study since the heat transfer mechanism and flame spread characteristics coupled these two factors are not clear yet.

Combustion Science and Technology, 1979
Abstract In the previous paper (Part I), results were given for unburnt fuel fraction and wall heat flux for boundary layer flows with combustion. In the present paper, a highly simplified model of the combusting plume region and the previous unburnt fuel results are used to obtain analytical results for the ratio of flame to gasification heights in ...

Concurrent flame spread over discrete fuel arrays is a dangerous flame configuration where flame spread has the same direction with induced airflow. However, inclined upward flame spread over discrete fuels is rarely concerned, especially for the varied ...

Steiner tunnel index as a measure of flame spread rate
Fire Technology, 1978The procedure by which a flame spread index is calculated in the Steiner Tunnel Test has recently been revised by ASTM. The new index is shown to measure average flame speed, weighted so as to emphasize the flame behavior in the earlier part of the test.

Flame Spread Rates Over Methanol Fuel Spills
Combustion Science and Technology, 1985Abstract Flame spread rates over pooled methanol and pooled gasoline were compared with flame spread rates over a porous surface saturated with these fuels. If the surface temperature was above the fuel flashpoint, the flame spread rate over a fuel-soaked porous surface was the same as for pooled fuel. Just below the flashpoint, flame spread was slower
