Download or read book Non linear Transport Techniques for Decreasing Ionization in Plasmas written by ROBERT M. SNOW and published by . This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques for reducing plasma ionization to restore communications are discussed. Techniques whereby electrons are physically moved over significant distances by utilizing nonlinear processes in the interaction of electrons and radiation are investigated. Calculations indicate that by irradiating the plasma with the appropriate types of electromagnetic field, significant transport effects can be obtained. A systematic perturbation procedure is used for calculating such effects, leading to a 'pseudostatic field' which acts primarily on electrons while essentially ignoring particles of heavier mass. The pseudostatic field is a convenient artifice for the simplified description of dynamic trajectory effects; its status in this respect is strictly analogous to that of the classical 'Coriolis force'.

Available in PDF, EPUB and Kindle. Book excerpt: LE CALCUL DU TRANSFERT RADIATIF CONSTITUE UNE ETAPE ESSENTIELLE DANS LA MODELISATION NUMERIQUE DES PLASMAS THERMIQUES. LE RAYONNEMENT DEPEND FORTEMENT DE LA NATURE DU GAZ DANS LEQUEL IL EST ETABLI ET PEUT JOUER UN ROLE IMPORTANT DANS DIVERSES APPLICATIONS. DANS LE CAS D'UN GAZ MOLECULAIRE TEL QUE L'AIR, LE RAYONNEMENT EMIS PAR LES REGIONS CHAUDES EST FORTEMENT ABSORBE DANS LES REGIONS FROIDES PAR LES MOLECULES. IL EXISTE DE NOMBREUSES APPLICATIONS FAISANT INTERVENIR DES PLASMAS ETABLIS DANS L'AIR : TORCHES A PLASMA POUR LA PROJECTION ; PLASMAS DE RENTREE ATMOSPHERIQUE ; FOURS A ARC EN SIDERURGIE ET LA SYNTHESE DE NO EN CHIMIE. LE CALCUL DU RAYONNEMENT S'EFFECTUE A PARTIR DE L'EQUATION DU TRANSFERT RADIATIF QUI EST DIFFICILE A RESOUDRE A CAUSE DE LA COMPLEXITE DE LA REPARTITION SPECTRALE DU RAYONNEMENT ET DE L'EXISTENCE DES GRADIENTS DE TEMPERATURE, DE PRESSION ET DE CONCENTRATION. UNE PART IMPORTANTE DE CE TRAVAIL DE THESE CONCERNE L'ETUDE DES BANDES MOLECULAIRES DE L'AIR EMISES PAR LES ESPECES N 2, O 2, NO, N 2 +. DEUX METHODES APPROCHEES DE CALCUL DU TRANSFERT RADIATIF ONT ETE PRESENTEES DANS CE TRAVAIL, EN SUPPOSANT LE MILIEU EN EQUILIBRE THERMODYNAMIQUE LOCAL : - METHODE DU COEFFICIENT D'EMISSION NETTE EN MILIEU HOMOGENE ET ISOTHERME QUI PERMET DE CALCULER LA TEMPERATURE DANS LES REGIONS CHAUDES AVEC UNE PRECISION CONVENABLE. - METHODE DU COEFFICIENT MOYEN D'ABSORPTION QUI CONSISTE A DECOUPER LE SPECTRE DE FREQUENCE EN QUELQUES INTERVALLES EN SUPPOSANT QUE SUR CHAQUE INTERVALLE SPECTRAL LE COEFFICIENT D'ABSORPTION TOTAL RESTE CONSTANT. LES BANQUES DE DONNEES OBTENUES PAR CES DEUX METHODES ONT ETE APPLIQUEES AU CALCUL DU TRANSFERT RADIATIF DANS LE CAS SIMPLE MONODIMENTIONNEL ET SUIVANT UN PROFIL DE TEMPERATURE. IL EST MONTRE QUE L'ABSORPTION EST TRES IMPORTANTE DANS LA GAMME U.V. ET QU'UNE FAIBLE EPAISSEUR D'AIR FROID AUTOUR DU PLASMA AUGMENTE CONSIDERABLEMENT L'ABSORPTION.

Download or read book Quantum Mechanics Volume 3 written by Claude Cohen-Tannoudji and published by John Wiley & Sons. This book was released on 2019-12-16 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.
