Three new surrogate fuels (n-decane

the mixed fuel of n -decane and 1

2

4-trimethylbenzene

the mixed fuel of n -decane and toluene) for kerosene(Jet A-1) were chosen

and detailed reaction mechanisms (67 species and 344 reactions for n -decane

118 species and 527 reactions for the mixed fuel of n -decane and 1

2

4-trimethylbenzene

and 84 species and 440 reactions for the mixed fuel of n -decane and toluene) for the ignition and combustion of these three surrogate fuels were analyzed.The ignition characteristics and the premixed combustion processes of these three surrogate fuels in the shock tube and the perfectly stirred reactor were simulated especially

and the simulation results were compared with the experimental data.Furthermore

the effect of volume percentage of two species in the mixed fuel on the ignition and premixed combustion characteristics were analyzed.The results show that these two mixed fuels represent the ignition and combustion characteristics of Jet A-1 more accurately than n -decane single fuel does.At the same time

the effect of volume percentage of two species in the mixed fuel on the ignition and premixed combustion characteristics are remarkable.
