Book Energy Transfer and Chemistry of Carbon Monoxide in Vibrational Mode Non equilibrium

Download or read book Energy Transfer and Chemistry of Carbon Monoxide in Vibrational Mode Non equilibrium written by Katherine Anne Essenhigh and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Chemical reactions with vibrationally excited carbon monoxide show a marked enhancement over thermal reaction rates. These reactions were studied experimentally, in the gas phase, and on selected surfaces. In addition, vibrational energy transfer between CO (carbon monoxide) and N2 (nitrogen) in cryogenic liquids was studied. For these experiments, energy was partitioned into the vibrational modes of the reactant CO, by absorption of the infrared radiation from a carbon monoxide laser. The product, CO2 (carbon dioxide) from reactions of the vibrationally excited CO molecules was measured. Systematic variation of the vibrational mode energy loading was achieved by adding varying amounts of helium, which provides a channel for fast vibrational relaxation of the higher vibrational levels. The specific rate for the gas phase Boudouard disproportionation reaction CO + CO -> CO2 + C, was measured for the vibrationally excited CO reactant, at relatively low gas kinetic temperatures. An activation energy near 6.0 eV (140 kcal/mole) was inferred. Quantitative measurements in the gas phase reaction yield a kinetic rate on the order of k[subscript overall] = 1.0*10−18 [cm3/sec], for an energy loading of the CO vibrational mode of 0.260 eV/molecule, at a translational mode temperature of 1050 K. For these conditions the vibrational states were in a strongly vibration-to-vibration pumped distribution with at least v = 35 being populated. With this same total vibrational mode energy loading, the rate decreases as higher vibrational quantum levels are quenched by the helium addition. These results are used to determine the validity of a rate based on a transition state theory describing the vibrational quantum state dependence of the chemical kinetic reaction rate. In other phases of this research, qualitative observations of the vibrationally activated chemistry of the CO on surfaces (copper oxide) have shown a production of CO2, at surface temperatures below 200 0C. At these temperatures, thermal equilibrium reactions on the same surface show no CO2 production. Vibrational mode power loading was also created in cryogenic (87K) liquid CO and argon, and vibration-to-vibration pumping of N2 is observed. An infrared fundamental band spectrum from vibrationally excited N2 has been observed for the first time in emission.

Book Experimental and Computational Study of Vibrational Energy Transfer in Nitric Oxide

Download or read book Experimental and Computational Study of Vibrational Energy Transfer in Nitric Oxide written by Allen Ray White and published by . This book was released on 2007 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The present work resulted in successful demonstration of vibrational up-pumping of nitric oxide with a line-selected CO laser both at steady state and at repetitively pulsed conditions. The laser was operated on a 8-->7 P(11) line which has a very good resonance with the 0-->1 vibrational transition of NO, with output power of approximately 5W. First overtone infrared emission from vibrational levels up to v=14 was measured with a Fourier Transform Infrared spectrometer operating in both rapid-scan (for steady-state measurements) and time-resolved step-scan (for time-resolved measurements) modes for three different NO partial pressures, P=0.1, 0.2, and 0.3 Torr, and Ar diluent pressure of PAr=100 Torr. The experimental results demonstrated that up to 14 NO vibrational levels (at steady state) and up to at least 10 vibrational levels (in time-resolved measurements) are populated and radiating. Vibrational distribution functions inferred from the steady-state IR emission spectra demonstrate deviation from the Boltzmann distribution, due to the effect of an-harmonic vibration-vibration pumping. A kinetic model, incorporating processes of laser beam absorption and stimulated emission, vibration-vibration (V-V) and vibration-translation (V-T) energy exchange, spontaneous radiative decay of NO, and diffusion of vibrationally excited molecules out of the laser-excited volume was used to model the experimental results. Comparison of the experimental results and the modeling calculations showed that the predicted time-resolved NO IR emission lags behind the experimentally measured emission, both during the excitation and during the relaxation. Incorporating Gaussian laser beam power distribution improved agreement for low vibrational levels but varying the NO-NO V-V rates, incorporating multi-quantum V-V and vibrational energy "sink" processes, and varying the focused laser beam diameter and the emission signal collection pattern did not result in further improvement of the agreement with the experiment. Comparative analysis of previous and the present optical pumping experiments strongly suggests that a combination of two factors, (1) the use of a focused pump laser beam, and (2) line-of-sight averaging signal collection introduces significant uncertainty into the input parameters of the kinetic model. For this reason, accurate kinetic modeling and inference of the V-V rates from these experiments is difficult.

Book Gasdynamics of Explosions and Reactive Systems

Download or read book Gasdynamics of Explosions and Reactive Systems written by A. K. Oppenheim and published by Elsevier. This book was released on 2013-10-22 with total page 787 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas Dynamics of Explosions and Reactive Systems documents the proceedings of the 6th Colloquium held at the Royal Institute of Technology in Stockholm, Sweden, 22-26 August 1977. The meeting was held under the auspices of the Royal Swedish Academy of Sciences and the International Academy of Astronautics. The scientific program included over one hundred papers. The contributions in this volume are organized into four parts. Part I contains papers on gaseous detonations. It covers topics such as theoretical model of a detonation cell; spherical detonations in hydrocarbon-air mixtures; and shock wave propagation in tubes filled with water foams. Part II presents studies on explosions, such as the detonation of hydrogen azide and propagation of a laser-supported detonation wave. Part III examines condensed phase detonations. It includes papers on the mechanism of the divergent and convergent dark waves originating at the charge boundary in detonating liquid homogeneous explosives with unstable detonation front; and initiation studies in sensitized nitromethane. Part IV presents discussions on turbulent detonations, covering topics such as the computational aspects of turbulent combustion and problems and techniques in turbulent reactive systems.
