Experimental Techniques in the Study of Laminar Flame Spread Over Solid Combustibles

Abstract
Discussions are given of a variety of experimental methods that have been found useful for studying the mechanisms by which laminar flames spread over combustible solid materials. These include motion-picture and still photography, thermocouple measurement of gas-phase and solid-phase temperatures, interferometric temperature measurements, radiometer measurements, gas sampling and analysis by gas chromotography, particle-track photography and pulsed-wire velocity measurements. The paper contains some new and previously unpublished results obtained by these techniques.
