A comprehensively tested H2/O2 chemical kinetic mechanism based on Mueller
et al. [1] and recently published kinetic and thermodynamic information is presented.
The revised mechanism is validated against a wide range of experimental conditions,
including those found in shock tubes, flow reactors, and laminar premixed flame.
Excellent agreement of the model predictions with the experimental observations
demonstrates the mechanism is comprehensive and has good predictive capabilities for
different experimental systems, including new results published subsequent to the work
of Mueller et al. [1], particularly high pressure laminar flame speed and shock tube
ignition results. The reaction H+OH+M is found to be primarily significant only to
laminar flame speed propagation predictions at high pressure. All experimental hydrogen
flame speed observations can be adequately fit using any of the several transport
coefficient estimates presently available in the literature for the hydrogen oxygen system
simply by adjusting the rate parameters for this reaction within their present uncertainties.
