In this paper, Large Eddy Simulation (LES) of combustion adopting Partially Stirred Reactor (PaSR) combustion model is performed for a full-scale kerosene fueled RBCC engine. In order to investigate the applicability and accuracy of the seven different kerosene global reaction mechanisms in RBCC, the ignition delay time, distribution of temperature and species are investigated based on operating conditions of RBCC. A 10-Step global reaction (C11H21) is proved to be the reasonable reactions. The combustion characteristics of two RBCC configurations (different strut locations) operating at scramjet mode are investigated by using compressible LES solver, which is implemented in an Open source Field Operation and Manipulation (OpenFOAM). The code is validated against experimental wall pressure, the results are satisfactory. Then, the wall pressure distribution, heat release, area-average Mach number, combustion efficiency and flame structure of the two configurations are studied.
