WebJul 5, 2024 · Moreover, the flame front definition is somewhat arbitrary with this optical technique; especially in case of saturated images obtained by direct visualization (Chanut et al. 2024). Shadowgraphy seems the best technique to detect the flame front. There is less luminosity variation during the propagation than with direct visualization. A flash fire is defined by NFPA 2112 (Standard on Flame-Resistant Clothing for Protection of Industrial Personnel Against Short-Duration Thermal Exposures from Fire) as: "A type of short-duration fire that spreads by means of a flame front rapidly through a diffuse fuel, such as dust, gas, or the vapors of an ignitable liquid, without the production of damaging pressure."
