Study on Ignition Delay and Reaction Mechanism of RP-3/Air Combustion Adding C(6)F(12)O

[Image: see text] RP-3 jet fuel is the main fuel for aircraft in China, and it is also a source of fire. C(6)F(12)O (Novec 1230) has an outstanding fire extinguishing performance and minimal environmental impacts. In this study, the application of C(6)F(12)O in the inhibition of RP-3 jet fuel fire was considered, and the ignition delay time (IDT) of C(6)F(12)O/air and RP-3/air adding C(6)F(12)O was measured using a shock tube. In addition, the results showed that the IDT of C(6)F(12)O was 500–900 μs and less sensitive to temperature compared with those of common fuels in the range of 1150–1958 K, and the influence of C(6)F(12)O on the IDT of RP-3 jet fuel was influenced by many factors including temperature, the concentration of C(6)F(12)O, and the stoichiometric ratio of RP-3 jet fuel. According to the experimental results, the mechanism of C(6)F(12)O was verified and modified, and then integrated with the mechanisms of RP-3 jet fuel; the integrated mechanism can well predict the IDT of C(6)F(12)O/air and RP-3/air adding C(6)F(12)O. This work provides a good basis for the chemical kinetics analysis of the inhibition of RP-3 jet fuel combustion by C(6)F(12)O.
