In order to obtain a reduced methane combustion mechanism for predicting combustion field and pollutants accurately in CFD simulations with a lower computational cost,a reduced mechanism with 22 species and 65 steps of reactions from GRI-Mech 3.0 was obtained by direct relation graph method and sensitivity analysis.The ideal reactor calculation and VV&A (Verification,Validation,and Accreditation) in CFD were carried out using the proposed mechanism.The results showed that the proposed mechanism agrees well with the detailed mechanism in a wide range of operating conditions;the temperature field and species can be predicted accurately in CFD simulations (RANS and LES models),and the NO prediction error of an industrial gas turbine combustor outlet is less than 2×10-6.The proposed mechanism has high engineering values.
