The objective of this study is to understand the effects of fuel volatility on soot emissions.
This effect is investigated in two experimental configurations: a jet flame and a model gas
turbine combustor. The jet flame provides information about the effects of fuel on the spatial
development of aromatics and soot in an axisymmetric, co-flow, laminar flame. The data from
the model gas turbine combustor illustrate the effect of fuel volatility on net soot production
under conditions similar to an actual engine at cruise. Two fuels with different boiling points …

Stricter environmental requirements, worldwide air traffic growth, and unsteady fuel prices all
has led to an increased interest in alternative jet fuels. Additionally, several nations are
investing resources identifying local fuel sources to make the fuel supply more resilient
against disruptions and flexible to use of multiple, reliable fuel stocks. The alternative jet
fuels that are being defined have unusual molecular distributions relative to current fuels.
These differences in molecular structure affect the gas-phase kinetics during combustion …
