Available in PDF, EPUB and Kindle. Book excerpt: Emissions at 450 nm and 4.27 micrometers have been measured when a variety of mixtures containing H2, CO, either O2 or N2O, and Ar were heated behind reflected shock waves to temperatures of 2000-2850 K and total concentrations near 5 x 10 to the 18th power molecule/cc. These emissions were used to obtain absolute concentration - time data for both oxygen atoms and carbon dioxide. The data were then compared to the results of numerical integrations of the likely mechanisms. It was observed that quantitative agreement between calculations and observations were obtained for the H2/CO/O2/Ar system using recent high temperature literature rate constants. For the H2/CO/N2O/Ar system, the rate constant for the reaction: H + N2O yields N2 + OH was adjusted so as to fit the data. Here it was found that a good fit to both (O) and (CO2) profiles could be achieved with k = 3 x 10 to the -9th power exp( -113kJ/RT) cc/molecule. Comparison to data at lower temperatures suggests that this might be another example of a 'Non-Arrhenius' rate constant. The implications of these results to studies of hydrocarbon oxidation are discussed. (Author).

This book was released on 2018-11-13 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reactions: (1) H + O2 = OH + O; and (2) O + H2 = OH + H are the most important elementary reactions in gas phase combustion. They are the main chain-branching reaction in the oxidation of H2 and hydrocarbon fuels. In this study, rate coefficients of the reactions and have been measured over a wide range of composition, pressure, density and temperature behind the reflected shock waves. The experiments were performed using the shock tube - laser absorption spectroscopic technique to monitor OH radicals formed in the shock-heated H2/O2/Ar mixtures. The OH radicals were detected using the P(1)(5) line of (0,0) band of the A(exp 2) Sigma(+) from X(exp 2) Pi transition of OH at 310.023 nm (air). The data were analyzed with the aid of computer modeling. In the experiments great care was exercised to obtain high time resolution, linearity and signal-to-noise. The results are well represented by the Arrhenius expressions. The rate coefficient expression for reaction (1) obtained in this study is k(1) = (7.13 +/- 0.31) x 10(exp 13) exp(-6957+/- 30 K/T) cu cm/mol/s (1050 K less than or equal to T less than or equal to 2500 K) and a consensus expression for k(1) from a critical review of the most recent evaluations of k(1) (including our own) is k(1) = 7.82 x 10(exp 13) exp(-7105 K/T) cu cm/mol/s (960 K less than or equal to T less than or equal to 5300 K). The rate coefficient expression of k(2) is given by k(2) = (1.88 +/- 0.07) x 10(exp 14) exp(-6897 +/- 53 K/T) cu cm/mol/s (1424 K less than or equal to T less than or equal to 2427 K). For k(1), the temperature dependent A-factor and the correlation between the values of k(1) and the inverse reactant densities were not found. In the temperature range of this study, non-Arrhenius expression of k(2) which shows the upward curvature was not supported. Ryu, Si-Ok and Hwang, Soon Muk and Dewitt, Kenneth J.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: H2O time-histories were studied within the H2/O2 system using a tunable diode laser system and a pressure-driven shock tube. Stoichiometric H2/O2 mixtures were prepared in high amounts of argon dilution. The mixtures were heated using a shock tube with a driver length of 3.04 m, a driven length of 6.78 m, and an inner diameter of 16.2 cm. A tunable diode laser (TDL) was used to measure H2O concentration near the endwall region of the shock tube after the passage of the reflected shock wave, 1.6 cm from the endwall. Both the incident and transmitted beam intensities were measured using IR photodetectors. The laser was tuned to access the H2O transition at 7204 cm−1. Experiments in the H2/O2 system were performed from 1100 to 1500 K and at an average pressure of 2.8 atm. The experimental results were compared with a mechanism from Hong et al. (2011). Preliminary results show good agreement in ignition delay time between experiment and model. A computer routine was created to modify the absorption coefficient as a function of temperature to account for the temperature variation during the experiment due to the chemical reaction. After rescaling, the corrected H2O profiles showed excellent agreement with the chemical kinetics model. Topics related to mechanism validation, the potential effects of impurities, and measurement accuracy are also addressed in the thesis.

Download or read book Initiation in H2/O2 written by J. V. Michael and published by . This book was released on 2000* with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reaction between H2 and O2 has been studied in a reflected shock tube apparatus between 1662-2097 K. O-atom atomic resonance absorption spectrometry (ARAS) was used to observe absolute [O]t under conditions of low [H2]0 so that most secondary reactions were negligible. Hence, the observed [O]t was the direct result of the rate controlling reaction between H2 and O2. Three different reactions were considered, but experimental and ab initio theoretical results both indicated that the process, H2 + O2 - H + HO2, is the only possible reaction. After rapid HO2 dissociation, O-atoms are then instantaneously produced by H + O2 - O + OH. Using the ab initio result, conventional transition state theoretical calculations (CTST) with tunneling corrections give the expression: k = 1.228 x 10−18 T24̇328exp( -26926 K/T) cm3 molecule−1 s−1, applicable between 400 and 2300 K. This theoretical result agrees with the present experimental determinations and those at lower temperature, derived from earlier work on the reverse reaction.

Available in PDF, EPUB and Kindle. Book excerpt: The reaction between H2 and O2 has been studied in a reflected shock tube apparatus between temperatures of 1662 - 2097 K and pressures of 400 - 570 torr with Kr as the diluent gas. O atom atomic resonance absorption spectrometry (ARAS) was used to observe absolute [O]sub t under conditions of low [H2]sub 0 so that most secondary reactions were negligible. Hence, the observed [O]sub t was the direct result of the rate controlling reaction between H2 and O2. Three different reactions were considered, but experimental and ab initio theoretical results both indicated that the process, H2 + O2 -> H + HO2, is the most probable reaction. After rapid HO2 dissociation, O atoms are then instantaneously produced by H + O2 -> O + OH. Using the ab initio result, conventional transition state theoretical calculations (CTST) with tunneling corrections give the expression k(th/1) = 1.288 X 10( -18) T(2.4328) exp( -26,926 K/T) cu cm molecule( -1) s( -1), applicable between 400 and 2300 K. This theoretical result agrees with the present experimental determinations and those at lower temperature, derived from earlier work on the reverse reaction.
