Abstract

The mechanism of soot formation in flames, especially the initial chemical steps (nucleation), is being developed on a quantitative basis by experimentally studying low pressure premixed flames and interpreting the observations in terms of elementary steps. Because of the fundamental nature of the data obtained using this approach, the soot formation mechanism should also be applicable to other more complex systems such as high pressure engines and diffusion flames. Of course, the relative importance of individual steps in the process will change with the environment, but a quantitative understanding of what controls the individual steps should permit one to simulate the effects of these changes and include them in the model. Soot is a combustion product which increases plume visibility and, hence, aircraft vulnerability, and may cause reduced engine durability. In the past, fuel additive use has been shown, qualitatively, to be effective in reducing soot.
