A process of elimination again produces "the 00's," pronounced "the Oh's". History's no help in this search.
The OH time histories show significant sensitivity to the OH + OH + M = H2O2 + M, CH3 + HO2 = CH3O + OH, and CH3 + HO2 = CH4 + O2 reactions, which have rate coefficients with relatively high uncertainties.
Detailed comparisons of these OH time-histories with the predictions of various kinetic mechanisms were made.
Improved predictions of the OH time histories can be achieved by modifying the rate coefficient for these reactions.
For ethylamine oxidation, ignition delay times, and NH2 and OH time-histories were measured in ethylamine/O2/argon mixtures.
In addition, H2O and OH time-histories were recorded during the oxidation of cyclohexane, methylcyclohexane, n-butylcyclohexane, iso-octane and n-heptane under similar test conditions.
Existing silane combustion kinetics mechanisms capture many of the experimentally observed features of the system, yet fail to quantitatively reproduce the OH time histories in their entirety.
OH time-histories near time zero are distinctive for each type of fuel studied, and these early-time OH profiles provides critical insight into the influence of molecular structures on ignition behavior, particularly in the case of the cycloalkanes.
Current results are the first quantitative measurements of OH time-histories during high-pressure oxidation of these fuels, and hence are a critical step toward development of accurate reaction models for jet fuel surrogates.
Oh, counterfactual history, where bacon sandwich jokes are our biggest concern, the Lib Dems are there for a reason, and Paddy Ashdown hasn't eaten any hats!
