- Abstract
- Experiments were conducted in which the burning of cylindrical maerials in a flowing oxidant stream was studies. Plexiglas, nylon, and Teflon fuel specimens were oriented such that the flames spread along the surface in a direction opposed to the flowing gas. Results of the effects of pressure, oxygen concentration, and gas velocity on flame spread rate substantiated and extended the work in the literature. Three regions were defined for the behavior of the flame spread rate as a function of gas velocity. Sufficient information was obtained in two of the regions to provide data correlations which were power law relations in terms of pressure, oxygen concentration, and gas velocity.
