Abstract

Soot nanostructure can reflect the gas-phases species contributing to its formation. In previous studies of soot from a commercial gas turbine engine (GE CFM56 2C3) burning petroleum-derived and synthetic-based fuels, the soot nanostructure exhibited a progression associated with fuel compositions and engine conditions. In this study, two main parameters -adiabatic flame temperature (1600 & 2000oC) and fuel/air equivalence ratio (2.0 & 2.2) were varied to test their relative impact on soot nanostructure formation The soots were collected from the flat flame burning the petroleum based -JP-8, synthetic -FT, and the surrogates -Iso-Octane/n-Dodecane, m-Xylene/n-Dodecane, n- Heptane/n-dodecane, and n-Dodecane fuels on a McKenna burner. Images from highresolution transmission microscope (HRTEM) show that with higher adiabatic flame temperature and lower equivalence ratio contributes more fullerene- and graphitic-like carbon lamellae to the soot. Notably soots from synthetic-FT, and aliphatic -n- Dodecane fuels exhibit significant nanostructure at each tested condition and no progression with flame conditions.

Images from highresolution transmission microscope (HRTEM) show that with higher adiabatic flame temperature and lower equivalence ratio contributes more fullerene- and graphitic-like carbon lamellae to the soot. Notably soots from synthetic-FT, and aliphatic -n- Dodecane fuels exhibit significant nanostructure at each tested condition and no progression with flame conditions.
