Integration of new jet fuels for use in commercial and military applications relies on a fundamental understanding of not only the physical and chemical properties of the fuels, but more importantly, the behavior of these fuels in combustion devices. Fuels derived from alternative sources, including biological, coal, and natural gas sources, can have widely varying chemical and physical properties, and as such, their combustion characteristics may be exceedingly different from standard fossil-derived fuels. Significant research efforts have yielded a better understanding of the impact of chemical composition of new fuels on combustion. However, there are a number of significant gaps in our understanding of how soot forms in jet fuel flames. The focus of this work is to understand soot formation processes in flames with a range of jet fuels and fuel surrogates.
