Experimental Study of the Optical Properties of Soot and Smoke (NISTIR 5499)



M Y. Choi, George W. Mulholland, Anthony Hamins, Takashi Kashiwagi


The accurate measurement of flame-generated particlates is a problem of current interest to researchers in the fire and combustion community. Within the flame, the soot concentration measurement is central to the study of soot growth and for radiant transport analysis. In the post-flame region of large fires, particulate measurements are important in developing computational modeling of smoke plume movement, in the detection fires, in assessing the reduction in visibility arising from a fire within a building and for estimating the health and environmental impacts.
