Flame front definition
WebNov 17, 2010 · Flashover is the transition phase in the development of a contained fire in which surfaces exposed to the thermal radiation, from fire gases in excess of 600° C, reach ignition temperature more or less simultaneously and fire spreads rapidly through the space. This is the most dangerous stage of fire development. Videos: Compartment Fire Flashover 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.
