Abstract

A systematic approach for mechanism reduction was developed and demonstrated. The demonstration was performed for a detailed ethylene oxidation mechanism consisting of 70 species and 463 elementary reactions, resulting in a specific skeletal mechanism consisting of 33 species and 205 elementary reactions, and a specific reduced mechanism consisting of 20 species and 16 global reactions. Calculations for laminar flame speeds and non-premixed counterflow ignition using either the skeletal mechanism or the reduced mechanism showed very close agreement with those obtained by using the detailed mechanism over wide parametric ranges of pressure, temperature and equivalence ratio.
