Ignition and Combustion Characteristics of a Surrogate Fuel for Jet A-1 Kerosene

A new surrogate fuel(the mixed fuel of n-decane and 1,2,4-trimethylbenzene)for kerosene(Jet A1)was provided,and a reaction mechanism(including 118 species and 527 reactions)for the ignition and combustion of the surrogate fuel was compiled.The ignition characteristic of the surrogate fuel in the shock tube was simulated using the detailed reaction mechanism.Furthermore,the premixed combustion processes of the surrogate fuel in the premixed burner and the perfectly stirred reactor were simulated.The mole fractions of the reactants(such as n-C10H22 and O2),the major combustion products(such as CO,CO2,H2,and H2O),and the intermediate species(such as CH2O,C2H2,C2H4,C3H4,C3H6,C4H8,and C5H10)were analyzed.At the same time,the simulation results were compared with those of another surrogate fuel(n-decane)and the experimental data,respectively.The results show that the mixed fuel of n-decane and 1,2,4-trimethylbenzene as surrogate fuel can accurately reflect the ignition and combustion characteristics of Jet A-1,and is also better than those of n-decane.
