Comprehensive mechanism for the pyrolysis and oxidation of ethylene

Conference ·
OSTI ID:5290905

A detailed chemical kinetic reaction mechanism is developed for the intermediate and high temperature pyrolysis and oxidation of ethylene. The mechanism, consisting of 93 elementary reactions among 26 chemical species, is validated by comparison between computed results and measured data from shock tube and turbulent flow reactor experiments. New rates expressions are determined for a number of reactions between C/sub 2/H/sub 4/ molecules and H, O, and OH radicals. The comprehensive mechanism accurately reproduces available experimental data for pressures ranging from 1 to 12 atmospheres and for fuel-air equivalence ratios from 0.125 to pyrolysis conditions. The resulting mechanism then predicts correctly laminar flame and detonation properties for ethylene-air mixtures.
