The paper presented a numerical simulation of turbulent flow in a reduced aero-engine combustor model with the detailed chemical kinetic mechanisms of n-C7H16.Under the two-dimensional body-fitted grid

the turbulent characteristics were estimated by k-ε equations

the reacting rate was estimated by eddy dissipation concept(EDC) model.In the paper the reacting model was perfectly stirred reactor(PSR)

the concentrations of the major components and thermal flow results were gotten

and the relationship between some certain components validated the feasibility.The results of the EDC model basically agree with the one-step reactions with EBU-SRK(eddy break up-simplified reaction kinetics) model.
