Constant volume combustion chamber (CVCC) investigations of aerospace F-24 and Jet-A in low-temperature heat release and negative temperature coefficient regions

A study was conducted to determine the characteristics of Low Temperature Heat Release, Derived Cetane Number, and Vibrations, produced by combustion aerospace F24 using Jet-A as a baseline in Constant Volume Combustion Chamber. The Ignition Delay for F-24 were found be 4.04 ms 5.71 with DCN resulting at 43.77. have larger 47 an ignition delay 3.35 5.14 ms. has extended region cool flame releases more its energy during LTHR than Jet-A, however much shorter NTCR that Jet-A. From NVH analysis it there exists strong correlation between ID CD phases their respective spectrum. It magnitude ringing 3x higher F24. Meanwhile, vibrations Jet approximately 0.5 g greater those F24?s which correlates well peak value AHRR also compared
