This book was released on 1986 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: When air is heated and becomes highly ionized, the primary constituents cnsist of nitrogen, oxygen and their ions. Emissions from this plasma provide diagnostic information as well as contribute to cooling the plasma. To describe such a plasma under nonequilibrium conditions one must known the population densities of various excited states. Using a time dependent approach a collisional-radiative model is developed for an oxygen plasma. Effective recombination and ionization coefficients are calculated for two specific cases, optically thin and optically thick in bound-bound UV radiation. The steady state population densities for neutral and ionic states are presented in terms of their deviations from Saha equilibrium predictions. These results show the approach of the plasma to a state of local thermodynamic equilibrium (LTE) as a function of electron temperatures between 1.0 and 3.0 eV and electron densities between 10 to the 16th power and 10 to the 19th power/cc.

Available in PDF, EPUB and Kindle. Book excerpt: This authoritative reference presents a comprehensive review of the evolution of plasma science and technology fundamentals over the past five decades. One of this field’s principal challenges has been its multidisciplinary nature requiring coverage of fundamental plasma physics in plasma generation, transport phenomena under high-temperature conditions, involving momentum, heat and mass transfer, and high-temperature reaction kinetics, as well as fundamentals of material science under extreme conditions. The book is structured in five distinct parts, which are presented in a reader-friendly format allowing for detailed coverage of the science base and engineering aspects of the technology including plasma generation, mathematical modeling, diagnostics, and industrial applications of thermal plasma technology. This book is an essential resource for practicing engineers, research scientists, and graduate students working in the field.

This book was released on 2015-11-26 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describing non-equilibrium "cold" plasmas through a chemical physics approach, this book uses the state-to-state plasma kinetics, which considers each internal state as a new species with its own cross sections. Extended atomic and molecular master equations are coupled with Boltzmann and Monte Carlo methods to solve the electron energy distribution function. Selected examples in different applied fields, such as microelectronics, fusion, and aerospace, are presented and discussed including the self-consistent kinetics in RF parallel plate reactors, the optimization of negative ion sources and the expansion of high enthalpy flows through nozzles of different geometries. The book will cover the main aspects of the state-to-state kinetic approach for the description of nonequilibrium cold plasmas, illustrating the more recent achievements in the development of kinetic models including the self-consistent coupling of master equations and Boltzmann equation for electron dynamics. To give a complete portrayal, the book will assess fundamental concepts and theoretical formulations, based on a unified methodological approach, and explore the insight in related scientific problems still opened for the research community.

This book was released on 1975 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Number densities of several excited states of atomic oxygen and nitrogen have been measured in the decaying non-thermal plasma of a theta-pinch afterglow. The spatial variation of the electron density and temperature as a function of time after the initiation of main bank discharge have also been measured to facilitate a comparison of excited state number densities with model calculations. Measurements of the atomic oxygen excited states indicate that quintet to triplet spin exchange collisions and doubly excited states must be included in the model. The measured populations of the excited atomic nitrogen states agree well with those calculated at high density but disagree badly at lower densities. The discrepancies seem to be real since they are larger than expected measurement uncertainty.

Available in PDF, EPUB and Kindle. Book excerpt: A collisional-radiative model for nitrogen plasma (N, N+, and N++) has been developed. The results for an optically thin, and optically thick in uv lines, are presented. The approach taken in the model is to solve a time dependent set of rate equations for a large number of excited states of N and N+ for a wide range of Tellurium and Neon. The excited states of interest emit radiation in the ultraviolet, visible and infrared which could be used for air plasma channel diagnostics. The model delineates the regimes in Te and Ne where the excited states are in Local Thermodynamic Equilibrium and when they deviate from LTE, and is developed as a building block for an extensive radiative transfer model for air.
