| Abstract: | A new optimization-based approach to kinetic model reduction is presented.The reaction-elimination problem was formulated as a linear integer program was the smallest possible reduced model consistent with the user-set tolerances.The method is applied to GRI-Mech 3.0 reaction mechanism consisting of 325 reactions and 53 species to generate optimally-reduced models for isobaric,adiabatic homogeneous methane combustion.The computational accuracy of the reduced models is compared to that of the full mechanism.The chemical process of methane combustion was revealed by sensitivity analysis. |
