Impact of vitiation on flow reactor studies of jet fuel combustion chemistry

Flow reactors are commonly employed in investigations of the pyrolysis and oxidation chemistry fuels. Typical flow use either electrical heaters or vitiation to provide energy preheat reactants desired experimental conditions. The present study seeks determine impact on reactor studies fuel combustion by conducting both experiments a which an heater is used as source. Other than all other aspects identical. Two fuels relevant air-breathing propulsion systems were investigated – Jet A JP-10. Profiles stable reaction products measured using gas chromatography for temperature 1030 K at pressure 1 atmosphere, with residence times between 30 ms 70 ms. primary hydrocarbon C2H4, C3H6, CH4, C4H8, C6H6 C7H8. For JP-10, addition these species, cyclopentene (C5H8) cyclopentadiene (C5H6) measured. Under conditions investigated, decreases scales oxidation. However, product yields fixed conversion nearly identical vitiated non-vitiated experiments. Current kinetic models JP-10 adequately captured observed effects species profiles.
