For the Computational Fluid Dynamics (CFD) modeling of combustion and detonation of Jet A aviation fuel it is necessary to use the simplest kinetic mechanism that accurately describes the essential relevant phenomena. A surrogate that demonstrated good agreement with the parent fuel in the detonation process was chosen. A detailed kinetic mechanism was elaborated using a multilevel approach. A reduced mechanism was derived from the detailed mechanism for use in the CFD simulation of real detonation processes in combustors.
