This book was released on 1992 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ETUDE THEORIQUE DES CARACTERISTIQUES ANISOTROPES D'UNE TURBULENCE HOMOGENE SOUMISE A DES GRADIENTS MOYENS PLANS EST ABORDEE DANS L'ESPACE SPECTRAL. DIFFERENTS COUPLAGES DU TAUX DE ROTATION/DEFORMATION SONT EXAMINES DE PART ET D'AUTRE DU CAS CENTRAL DE CISAILLEMENT PUR. LA RESOLUTION DU PROBLEME LINEAIRE EST REALISEE SUR L'EQUATION DU SPECTRE DE LA FLUCTUATION DE VITESSE. LA SOLUTION NUMERIQUE EST DETAILLEE DANS LE CAS DES ECOULEMENTS ELLIPTIQUES AFIN DE FAIRE LE LIEN AVEC LES ETUDES DE STABILITE DE CES ECOULEMENTS PERIODIQUES. L'APPROCHE NON LINEAIRE PORTE SUR L'EQUATION DU TENSEUR SPECTRAL D'ORDRE 2. UNE FERMETURE DU TYPE EDQNM EST UTILISEE POUR DECRIRE L'EVOLUTION DES CORRELATIONS TRIPLES. LE CALCUL DU TERME NON LINEAIRE DE L'EQUATION DE CRAYA EST SIMPLIFIE EN UTILISANT UNE DECOMPOSITION EN HARMONIQUES SPHERIQUES POUR LE TENSEUR D'ORDRE 2. L'ETUDE EXPERIMENTALE, MENEE PARALLELEMENT, FOURNIT LES EVOLUTIONS ANISOTROPES DES TENSIONS DE REYNOLDS POUR LES CAS DE COUPLAGE SUIVANTS: DEFORMATION PURE PLANE, DEFORMATION DOMINANTE, CISAILLEMENT PUR ET ROTATION DOMINANTE. LES RESULTATS LINEAIRES DONNENT LES TENDANCES DE L'ANISOTROPIE. PAR CONTRE, LE CALCUL NON LINEAIRE SE HEURTE A UN PROBLEME DE REALISABILITE DU TENSEUR SPECTRAL.

Available in PDF, EPUB and Kindle. Book excerpt: CETTE ETUDE EXPERIMENTALE A ETE REALISEE AFIN DE CARACTERISER L'EVOLUTION TEMPORELLE DU MELANGE D'UN SCALAIRE PASSIF DANS UN FLUIDE TURBULENT. UN SCALAIRE EST INJECTE DANS LE CHAMP LOINTAIN D'UN JET TURBULENT D'EAU (RE = 6000) A L'AIDE D'UN TUBE DONT LE DIAMETRE EST BEAUCOUP PLUS PETIT QUE L'ECHELLE INTEGRALE LOCALE DU JET PRINCIPAL. ON PEUT ETUDIER LES DIFFERENTES ETAPES DU MELANGE EN OBSERVANT LE CHAMP DE CONCENTRATION A DIFFERENTES DISTANCES DE LA SORTIE DU TUBE D'INJECTION (DE ZERO A UNE ECHELLE INTEGRALE). EN UTILISANT LA FLUORESCEINE (SC = 2000), ON PEUT VISUALISER LE SCALAIRE SUR UN PLAN PAR FLUORESCENCE INDUITE PAR LASER ET MESURER L'EVOLUTION DU VOLUME OCCUPE ET LA GEOMETRIE DE L'INTERFACE SCALAIRE-EAU CLAIRE. EN PARTICULIER ON TROUVE QUE LA GEOMETRIE DE LA DISTRIBUTION DU SCALAIRE DEPEND FORTEMENT DU NIVEAU DU SEUIL DE CONCENTRATION CHOISI. DE TECHNIQUES DE MESURE DE LA CONCENTRATION LOCALE, NOUS ON PERMIS DE CALCULER LES PDFS ET LES SPECTRES DE PUISSANCE POUR DEUX TYPES DE SCALAIRE : FLUORESCEINE ET TEMPERATURE (SC = 7). DANS LE DEUX CAS, LE PDFS SONT BIEN DECRITES PAR UNE LOI EXPONENTIELLE, DONT L'ARGUMENT DECROIT LINEAIREMENT AVEC LE TEMPS (D'AUTANT PLUS RAPIDEMENT QUE LA DIFFUSIVITE EST FORTE). L'EVOLUTION DES SPECTRES DE PUISSANCE MONTRE PAR CONTRE UNE DIFFERENCE ENTRE LES DEUX CAS : DANS UN DOMAINE D'ECHELLES CONTENU DANS LA PLAGE INERTIELLE, ON OBSERVE UNE PENTE (-1) TRES NETTE DANS LE CAS DE LA FLUORESCEINE POUR TOUS LES TEMPS CONSIDERES, TANDIS QUE, POUR LA TEMPERATURE, LA PENTE SPECTRALE PASSE, DE FACON CONTINUE, DE (-1) A (-5/3) EN AUGMENTANT LE TEMPS. POUR INTERPRETER NOS RESULTATS EXPERIMENTAUX (ET EN PARTICULIER LA FORME EXPONENTIELLE DES PDFS), NOUS PROPOSONS UN MODELE BASE SUR LA REPRESENTATION DU CHAMP DE CONCENTRATION COMME UN ENSEMBLE DE PAQUETS, SOUMIS AU CHAMP DES ETIREMENTS INDUIT PAR LA TURBULENCE SOUS-JACENTE.
Download or read book Genmix written by D Brian Spalding and published by Elsevier. This book was released on 2014-05-18 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genmix: A General Computer Program for Two-dimensional Parabolic Phenomena explains a computer program called GENMIX. The main intention of the program is to be used as a tool of instructions. The name of the program is a mixture of two considerations: its generality and its concern for mixing processes. The book aims to help the potential user to understand the physical and mathematical basis of the topic computer program. It is also the aim of the book to make the program applicable to practical problems. The book is arranged in such a way as to parallel a course of lectures and associated computer-workshop sessions wherein the student is allowed to do some elementary computations as soon as he has gained some knowledge of the method. The book contains the mathematical, physical, and computer-coding aspects of the program. Concepts such as the boundary layer, two-dimensional, and steady- flow are defined and discussed in depth. The text will be a useful tool for computer instructors and students.

Download or read book Radioactive Aerosols written by Constantin Papastefanou and published by Elsevier. This book was released on 2011-07-28 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whenever radioactivity is released to the atmosphere, for example by the detonation of nuclear weapons or the testing of nuclear weapons or from nuclear reactor accidents that fraction of it which remains airborne for more than a few hours is liable to be attached to aerosol particles. The resulting radioactive aerosols are carried by atmospheric mixing processes until they settle out or are scavenged by precipitation. The radiation exposure pathway of maximum concern to humans is by inhalation of aerosols and their deposition in the respiratory tract. In this context, it is important to note that radioactive aerosols are commonly of natural origin alos. In particular, the associated radionuclides can be of natural terrestrial origin, such as the decay products of radon gas, or they can e cosmogenic, such as beryllium-7. The exposure of miners of uranium and other ores and minerals to radon and its aerosol-borne decay products is of major significance. The book describes the formation of aerosols, their aerodynamic size distribution, their atmospheric residence time, their sampling and measurement, the range of radioactive aerosols found and studied thus far, including man-made nuclides and radon decay products and their interaction with man, including deposition in the lung and subsequent health effects. - Advanced level science handbook for researchers, scientists and academics - Covers all aspects of radiation exposure in humans, including subsequent health implications - Presents the latest findings and analysis in this highly topical area

Download or read book Animal Sonar Systems written by R. Busnel and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 1097 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirteen years have gone by since the first international meet ing on Animal Sonar Systems was held in Frascati, Italy, in 1966. Since that time, almost 900 papers have been published on its theme. The first symposium was vital as it was the starting point for new research lines whose goal was to design and develop technological systems with properties approaching optimal biological systems. There have been highly significant developments since then in all domains related to biological sonar systems and in their appli cations to the engineering field. The time had therefore come for a multidisciplinary integration of the information gathered, not only on the evolution of systems used in animal echolocation, but on systems theory, behavior and neurobiology, signal-to-noise ratio, masking, signal processing, and measures observed in certain species against animal sonar systems. Modern electronics technology and systems theory which have been developed only since 1974 now allow designing sophisticated sonar and radar systems applying principles derived from biological systems. At the time of the Frascati meeting, integrated circuits and technol ogies exploiting computer science were not well enough developed to yield advantages now possible through use of real-time analysis, leading to, among other things, a definition of target temporal char acteristics, as biological sonar systems are able to do. All of these new technical developments necessitate close co operation between engineers and biologists within the framework of new experiments which have been designed, particularly in the past five years.
