N2 - The detailed kerosene high temperature mechanism of C10H22 consisting of 121 species 866 elemental reactions is reduced by DRG method and CSP importance index. A skeletal chemical mechanism of kerosene containing 41 species and 132 elemental reactions is finally obtained. The comparisons of flame temperature, ignition delay time, ignition process and extinction predicted by the skeletal mechanism show an overall good accordance with the detailed reaction mechanism. Moreover, a three-dimensional RANS modeling based on the skeletal kerosene mechanism and a global reaction with the single compound C11H21 is employed for the numerical analysis of a full-scale RBCC engine, which has been experimentally tested in a direct connect supersonic combustion test platform assembled in Science and Technology on Combustion, Internal Flow and Thermal-structure Laboratory (Northwestern Polytechnical University, Xi’an, China). Both the skeletal mechanism and C11H21 global reaction can demonstrate appropriate accuracy with the experiment result.
