Flame front definition

WebLaminar flame speed is defined as the propagation rate of the normal flame front relative to the unburned mixture. It is an important property for a premixed flame as it embodies the fundamental information of diffusivity, reactivity, and exothermicity of the combustible hydrocarbon mixture. WebA flame front generator is a system in which a gas/air mixture is introduced at ground level and flows up a one-inch line to the pilot burner. After filling this line with the mixture it is ignited by a spark. The resulting flame travels to the …

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. WebIn this configuration, the flame is typically initiated by way of a spark within a homogeneous pre-mixture. The subsequent propagation of the developed premixed flame occurs as a spherical front until the mixture is transformed entirely or the walls of the combustion vessel are reached.
