AI Article Synopsis
- RP-3 jet fuel is primarily used in China and is flammable, while CFO (Novec 1230) is effective at extinguishing fires with minimal environmental impact.
- This study measured the ignition delay time (IDT) of both CFO and RP-3 jet fuel using a shock tube, revealing that CFO has an IDT of 500-900 μs, which is less affected by temperature than common fuels.
- The research also explored how the IDT of RP-3 jet fuel is influenced by factors like temperature, CFO concentration, and the fuel's stoichiometric ratio, leading to an integrated mechanism that predicts the IDT of both CFO/air and RP-3/air mixes effectively.
Article Abstract
RP-3 jet fuel is the main fuel for aircraft in China, and it is also a source of fire. CFO (Novec 1230) has an outstanding fire extinguishing performance and minimal environmental impacts. In this study, the application of CFO in the inhibition of RP-3 jet fuel fire was considered, and the ignition delay time (IDT) of CFO/air and RP-3/air adding CFO was measured using a shock tube. In addition, the results showed that the IDT of CFO 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 CFO on the IDT of RP-3 jet fuel was influenced by many factors including temperature, the concentration of CFO, and the stoichiometric ratio of RP-3 jet fuel. According to the experimental results, the mechanism of CFO was verified and modified, and then integrated with the mechanisms of RP-3 jet fuel; the integrated mechanism can well predict the IDT of CFO/air and RP-3/air adding CFO. This work provides a good basis for the chemical kinetics analysis of the inhibition of RP-3 jet fuel combustion by CFO.
