Two-dimensional numerical simulation of reactive flow in aero-engine combustor with detailed chemical kinetic mechanisms

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.
