"The burning region is commonly referred to as the flame or flame front. In equilibrium, thermal diffusion across the flame front is balanced by the heat supplied by burning. Two characteristic timescales are important here. The first is the thermal diffusion timescale , which is approximately equal to See more Deflagration (Lat: de + flagrare, "to burn down") is subsonic combustion in which a pre-mixed flame propagates through a mixture of fuel and oxidizer.

Copyright © 2003 by McGraw-Hill Companies, Inc. Want to thank TFD for its existence? 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.

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. Applications [ edit] 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.

WebNov 30, 2011 · Motion of the flame kernel under conditions of intense turbulence. Spark plug is located at right hand side of the chamber (from Reference 26). Another experimental observation on ignition delay is the increase in the percent dispersion as longer mean flame travel times are encountered ( Fig. 32 ). WebIn normal combustion, this flame front moves throughout the fuel/air mixture at a rate characteristic for the particular mixture. Pressure rises smoothly to a peak, as nearly all the available fuel is consumed, then pressure falls as the piston descends.
