A New Method of Chemical Kinetic Model Reduction for CFD Applications (original) (raw)

A new method for kinetic model reduction is proposed, involving skeletal model reduction through the Directed Relation Graph method and optimization of rate constants via the Solution Mapping Method. Demonstrated using a hydrogen-oxygen model, the method effectively produces reduced models that approximate temperature profiles from the full model across various conditions, though limitations exist in replicating laminar flame speeds and ignition or extinction times in perfectly-stirred reactors.
