Rate constant calculations of H-Atom abstraction reactions from ethers by H(O) over dot(2) radicals
(American Chemical Society, 2014-01-31)
In this work, we detail hydrogen atom abstraction reactions from six ethers by the hydroperoxyl radical, including dimethyl ether, ethyl methyl ether, propyl methyl ether, isopropyl methyl ether, butyl methyl ether, and ...
Oxidation of ethylene-air mixtures at elevated pressures, part 1: experimental results
(American Institute of Aeronautics and Astronautics, 2014-03-26)
Shock-tube experiments have been performed to determine ignition delay times of undiluted ethylene air mixtures for temperatures from 1003 to 1401 K, at equivalence ratios from 0.3 to 2.0, and at pressures from 1.1 to 24.9 ...
Oxidation of ethylene-air mixtures at elevated pressures, part 2: chemical kinetics
(American Institute of Aeronautics and Astronautics, 2014-03-27)
A chemical kinetics submechanism for small molecular weight hydrocarbons was modified by adjusting rate constants to produce better agreement with recent ethylene ignition delay time data compared with an earlier version ...
Theoretical chemical kinetic study of the h-atom abstraction reactions from aldehydes and acids by Ḣ Atoms and ȮH, HȮ2, and ĊH3 radicals
(American Chemical Society, 2014-11-11)
We have performed a systematic, theoretical chemical kinetic investigation of H atom abstraction by H atoms and OH, HO2, and CH3 radicals from aldehydes (methanal, ethanal, propanal, and isobutanal) and acids (methanoic ...
Comparison of the performance of several recent hydrogen combustion mechanisms
(Elsevier ScienceDirect, 2014-03-12)
A large set of experimental data was accumulated for hydrogen combustion: ignition measurements in shock tubes (770 data points in 53 datasets) and rapid compression machines (229/20), concentration time profiles in flow ...
A comprehensive combustion chemistry study of 2,5-dimethylhexane
(Elsevier ScienceDirect, 2014-01-16)
Iso-paraffinic molecular structures larger than seven carbon atoms in chain length are commonly found in conventional petroleum, Fischer-Tropsch (FT), and other alternative hydrocarbon fuels, but little research has been ...
Optimization of a hydrogen combustion mechanism using both direct and indirect measurements
(Elsevier ScienceDirect, 2014-07-05)
The Keromnes et al. (2013) mechanism for hydrogen combustion has been optimized using a large set of indirect experimental data, consisting of ignition measurements in shock tubes (566 datapoints in 43 datasets) and rapid ...
Experimental and kinetic modeling study of 2-methyl-2-butene: allylic hydrocarbon kinetics
(American Chemical Society, 2015-03-20)
Two experimental studies have been carried out on the oxidation of 2-methyl-2-butene, one measuring ignition delay times behind reflected shock waves in a stainless steel shock tube, and the other measuring fuel, intermediate, ...
Comparison of the performance of several recent syngas combustion mechanisms
(Elsevier ScienceDirect, 2015-01-22)
A large set of experimental data was accumulated for syngas combustion: ignition studies in shock tubes (732 data points in 62 datasets) and in rapid compression machines (492/47), flame velocity determinations (2116/217) ...
An experimental and modeling study of propene oxidation. Part 2: Ignition delay time and flame speed measurements
(Elsevier ScienceDirect, 2014-09-11)
Experimental data obtained in this study (Part II) complement the speciation data presented in Part I, but also offer a basis for extensive facility cross-comparisons for both experimental ignition delay time (IDT) and ...
