The multi-component characterization fuel Jet-A world average (JW) of aviation kerosene was selected, and the soot generation process of the characterization fuel was numerically simulated by using large eddy simulation (LES) and detailed chemical reaction mechanism. The soot precursor generation, soot particle generation and oxidation process were predicted in detail. The results showed that the Dalian soot model can predict the spatial distribution of soot mass in the combustion chamber; for the physical quantity describing soot generation, the growth of soot quality slightly lagged behind that of particle number density; the spatial distribution of soot is mainly related to the distribution of equivalence ratio and temperature. The smaller the equivalence ratio and the higher the temperature, the smaller the amount of soot generated.
