Abstract

We discuss a recently developed chemical model reduction strategy based on the use of Computational Singular Perturbation (CSP) analysis. This strategy was used to develop comprehensive simplified chemical models starting from detailed hydrocarbon kinetics. In the present work, we examine the accuracy resulting from using these mechanisms, as compared with the detailed model, in both steady and unsteady flame environments, under strain-rate and curvature perturbations, and under ranges of mixture conditions. These comparisons quantify the errors resulting from different degrees of reduction, highlighting the consequences of a given degree of model reduction on accurate prediction of different elements of hydrocarbon flame structure.
