“…Fast-response piezoelectric pressure transducers were collocated at both window positions and were used to monitor the arrival of the reflected shock wave. Unlike some of the previous studies [8,11], pressure was not used as an ignition diagnostic, because the increase in pressure was not observable for all of the mixtures due to the high levels of dilution, with the exception of mixture 4 for comparison with Burcat et al [8].…”

“…4 compares the same three correlations for the stoichiometric mixture 2. Because of mixture 2's high argon dilution, the Burcat et al [8] correlation has again been omitted. As in the previous mixture, the Lamoureux et al [12] activation energy differs from the present results, but their general range of ignition times is within 50% of the mixture 2 data at higher temperatures.…”

“…Bowman's study presented two correlations, one for fuel-lean and one for fuel-rich conditions. Burcat et al studied ignition delay times behind reflected shock waves for ethane/oxygen/argon mixtures in the pressure range from 2 to 8 atm [8]. Although they recorded both the pressure trace and the light emission, they chose to use the pressure trace to define the ignition delay time.…”

“…To test the mechanism's prediction of ignition delay time in ethane/oxygen/argon mixtures, the data of Takahashi et al [47], consisting of ignition delays in 1% ethane/3.5% oxygen/95.5% argon mixtures between 1.5 -2.4 atm, and of Burcat et al [48], consisting of ignition delays in 2% ethane, 7% oxygen, 91% argon mixtures between 6.7 -8.3 atm was simulated. The results are shown in Figs.…”

The largest difference is between our rate expression and that of Chevalier at high temperature.

A comprehensive chemical mechanism to describe the oxidation of methane has been developed, consisting of 351 irreversible reactions of 37 species. The mechanism also accounts for the oxidation kinetics of hydrogen, carbon monoxide, ethane, and ethene in flames and homogeneous ignition systems in a wide concentration range. It has been tested against a variety of experimental measurements of laminar flame velocities, laminar flame species profiles, and ignition delay times. The highest sensitivity reactions of the mechanism are discussed in detail and compared with the same reactions in the GRI, Chevalier, and Konnov mechanisms. Similarities and differences of the four mechanisms are discussed. The mechanism is available on the Internet as a fully documented CHEMKIN data file at the address

The pyrolysis of selected C 3-C 5 allylic hydrocarbons has been studied using a single-pulse shock tube. A new single-pulse shock tube has been designed and constructed by recommissioning an existing conventional shock tube. This facility enables the investigation of high-temperature chemical kinetics with an emphasis on combustion chemistry. The modifications performed on the existing shock tube are described, and the details of the sampling system to analyze the species concentration using a gas chromatography-mass spectrometry-flame ionization detection (GC-MS with a flame ionization detector) system are also provided. This facility is characterized and validated by performing cyclohexene pyrolysis experiments. Furthermore, the performance of the shock tube is demonstrated by reproducing previous literature measurements on the pyrolysis of isobutene. Postvalidation, this setup is used to study the pyrolysis of trans-2butene and 2-methyl-2-butene (2M2B). A newly developed mechanism, NUIG-Mech1.0, is used to simulate the experimental data of propene, isobutene, 2butene, and 2M2B, allylic hydrocarbon fuels. A description using two different kinetic simulation approaches is provided using our isobutene experiments as a reference. We found no significant differences between the two methods. Additionally, the contribution of different reaction classes on fuel consumption is detailed and the influence of geometry on fuel consumption and first aromatic ring: benzene is discussed.
