Book excerpt: For some time now this laboratory has been utilizing nitrous oxide as a high temperature source of oxygen atoms. Recently, an independent technique has been used to calibrate the detector system for oxygen atoms. With this calibration factor known, more refined experiments have been performed in which the absolute oxygen atom concentration can be monitored as a function of time. It was found that only slight modifications of earlier rate constant assignments were required to quantitatively explain these new results. In this light it is now felt that the dissociation kinetics of N2O are reasonably well understood. Thus the CO2 production rate in N2O/CO mixtures has been measured in an attempt to determine k sub r. It is shown that small amount of impurities can drastically affect the CO2 production rate. Analysis of this impurity effect has yielded estimates of the actual recombination rate constant between 2100 and 3200 K. The value of k sub r determined in this way is shown to be consistent with the recent measurements of k sub d reported by Wagner, and Kiefer, which yielded normal activation energies for CO2 dissociation.

Available in PDF, EPUB and Kindle. Book excerpt: The recombination rate of oxygen was measured in a shock tube. The shock tube is unconventional in that airfoils have been inserted to expand the flow, and a constant-area channel placed behind the airfoils; thus the shock tube is effectively a low-expansion-ratio shock tunnel. The gas in the tube is first dissociated and set in motion by the shock wave, then flows through the expansion waves created by the airfoils, and is cooled, and finally enters the constant-area channel, where it recombines. Measurement of the degree of dissociation along the constant area channel enables one to calculate the recombination rate of the oxygen atoms. The measured recombination rate constants are compared with those obtained by reflecting the known dissociation-rate constants through the equilibrium constant. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The recombination rate of oxygen atoms was measured directly in thermally pre-dissociated pure oxygen in a shock tube at a temperature above 3000K. A discrepancy of two to three orders of magnitude between various earlier, indirectly obtained experimental data prompted the author to attempt a direct measurement of the recombination rate, in view of its importance in the analysis of the combustion process and in high-temperature gas dynamics.

Meyer and published by . This book was released on 1970 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recombination reaction CO+O+M yields CO2+M was studied in incident and reflected shock waves from 1200 K to 2300 K. The recombination rate constant has a slightly negative apparent activation energy and confirms an unusual behaviour of the temperature dependence of the recombination rate constant. The unimolecular dissociation of hydrogen peroxide was investigated near the low pressure limit. Experiments at 20atm indicated the beginning of the fall-off region. In addition, light absorption corresponding to a species which forms and is consumed again during the reaction, was observed around 2300A. This absorption is possibly due to HO2. The thermal dissociation of formaldehyde at low concentrations in argon was investigated at temperatures 1400

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).
