This book was released on 1999-01-27 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, the excitation and ionization of atmospheric gases has become an area of intense research. A large amount of data have been accumulated concerning the various elementary processes which occur when photons, electrons and ions collide with atoms and molecules. This scattered information has now been collected in a handbook for the first time, and the authors give a critical analysis of relevant data. This book is a comprehensive and detailed study of the available information and is distinguished by the following outstanding features: the consideration of a large number of atmospheric constituents, including H^O2, H, N^O2, N, O^O2, O, CO, CO^O2, H^O2O, HCl and some hydrocarbons the maximum number of space particles, including magnetospheric particles, are considered as projectiles: photons, electrons, hydrogen atoms, protons and helium ionsthe energy range under study corresponds to the real spectrum of cosmic fluxes, from threshold values for elementary processes up to several thousand keV the recommended values of cross sections, obtained from analysis of the available experimental data, are given in the handbook and their accuracy is estimated. These features make the handbook particularly valuable to specialists in the aeronomy of planets, comets and active perturbations, as well as to experimentalists and theoreticians working in the fields of plasma physics, atomic and molecular physics, physics of the upper atmosphere, chemical physics, optics and spectroscopy.

Download or read book A KINETIC APPROACH TO COLLISION PROCESSES IN GASES I SMALL AMPLITUDE PROCESSES IN CHARGES AND NEUTRAL ONE COMPONENT SYSTEMS written by and published by . This book was released on 1953 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: This approach appears adequate for the unified treatment of the dynamic properties of gases over a continuous range pressures from the Knudsen limit to the high-pressure limit where the aerodynamic equations are valid. Alterations are made in the collision terms of the Boltzmann equation; each collision conserves particle number, momentum, and energy; persistence of velocities angular dependence may be included. The approach illustrates a technique for a simple model involving the assumption of a collision time independent of velocity; this model is applied to the study of small amplitude oscillations of 1-component ionized and neutral gases. The initial value problem for unbounded space is solved by performing a Fourier transformation of the space variable and Laplace transformation on the time variable. For uncharged gases there results the correct adiabatic limiting law for sound-wave propagation at high pressures. For ionized gases the difference in the nature of the organization in the low-pressure plasma oscillations and in high-pressure sound type oscillations is studied. Two important cases are distinguished. If the wave length of the oscillations is long compared to either the Debye length or the mean free path, a small change in frequency is obtained as the collision frequency varies from zero to infinity. The accompanying absorption is small and reaches its maximum value when the collion frequency equals the plasma frequency. the other case refers to waves shorter than both the Debye length and the mean free path; these waves are characterized by a very heavy absorption.

Download or read book Kinetic Processes in Gases and Plasmas written by A Hochstim and published by Elsevier. This book was released on 2012-12-02 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kinetic Processes in Gases and Plasmas provides a survey of studies on transport and chemical kinetic processes in high temperature gases and plasmas. The book is concerned with conditions produced by the interaction of an object with the atmosphere at hypersonic velocities. The text also provides a foundation for the flow field equations which include chemical reactions and other transport processes, and to present in some detail the microscopic considerations underlying these calculations. Chapters are devoted to the discussion of topics such as the molecular theory of transport equations; transport processes in ionized gases; and inelastic energy transfer processes and chemical kinetics. Aerospace engineers, physicists, chemists, and astrophysicists will find the book a good reference material.

Available in PDF, EPUB and Kindle. Book excerpt: Results have been obtained by Fourier Transform Infrared Emission Spectrometry (FTIES) to determine the internal energy distribution in molecules whose states are consequent to three kinds of inelastic and/or reactive collision processes. (1) Free Jet Expansion. Gas that is vibrationally excited in the source by heating, corona discharge or chemical reaction is interrogated by FTIES after free jet expansion into vacuum. The observed marked departures from equilibrium give insight on RR, RT, RV and VV exchanges where R, T and V refer to rotational, vibrational and translational energy. (2) Inelastic Scattering from Surfaces. When free jets of CO2, CO2, N2O, and OCS are incident on a hot Pt surface the reflected molecule have enough vibrational excitation to be analyzed by FTIES. Vibrational and Rotational accommodation coefficients have been determined for these species over a range of surface temperatures. (3) Reactive Scattering from Surfaces. FTIES analysis has been carried out on nascent carbon dioxide molecules formed by the catalytic oxidation of carbon monoxide molecules incident on a Pt surface bathed in oxygen. Results indicated vibrational and rotational temperatures much higher than surface temperatures.

This book was released on 2017-09-27 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and cohesive overview of transport processes associated with all kinds of charged particles, including electrons, ions, positrons, and muons, in both gases and condensed matter. The emphasis is on fundamental physics, linking experiment, theory and applications. In particular, the authors discuss: The kinetic theory of gases, from the traditional Boltzmann equation to modern generalizations A complementary approach: Maxwell’s equations of change and fluid modeling Calculation of ion-atom scattering cross sections Extension to soft condensed matter, amorphous materials Applications: drift tube experiments, including the Franck-Hertz experiment, modeling plasma processing devices, muon catalysed fusion, positron emission tomography, gaseous radiation detectors Straightforward, physically-based arguments are used wherever possible to complement mathematical rigor. Robert Robson has held professorial positions in Japan, the USA and Australia, and was an Alexander von Humboldt Fellow at several universities in Germany. He is a Fellow of the American Physical Society. Ronald White is Professor of Physics and Head of Physical Sciences at James Cook University, Australia.
