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.
RP-3 kerosene is the most widely used aviation kerosene in China, and research on its chemical-kinetic mechanism is significant for understanding the combustion characteristics. Based on a novel four-component surrogate fuel consisting of -dodecane, 2,5-dimethylhexane, 1,3,5-trimethylbenzene, and decalin (54, 22, 14, and 10% by mole), the detailed chemical-kinetic mechanism of the corresponding RP-3 surrogate fuel with 1333 species and 6803 reactions has been developed and then reduced to 145 species and 818 reactions for high-temperature conditions. After that, the merged surrogate mechanism of surrogate fuel was validated by various experimental data sets for each individual surrogate component.
