This book was released on 1999 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: LE CADRE SIMPLIFIE DES MODELES EN COUCHES PERMET D'ETUDIER LE LIEN ENTRE LES PROPRIETES STATISTIQUES DES ECOULEMENTS TURBULENTS ET LA PRESENCE DE STRUCTURES QUI TRANSPORTENT L'ACTIVITE ENERGETIQUE DE MANIERE COHERENTE DES GRANDES VERS LES PETITES ECHELLES. L'IDEE DIRECTRICE EST QUE CES STRUCTURES CORRESPONDENT A DES FLUCTUATIONS PRIVILEGIEES DANS L'ESPACE CONFIGURATIONNEL. ON COMMENCE PAR RAPPELER LES PROPRIETES DE LA DYNAMIQUE DETERMINISTE DU MODELE GOY ET LES DONNEES STATISTIQUES REALISEES SUR L'ENREGISTREMENT DES PICS DU FLUX D'ENERGIE. PUIS EN PARAMETRISANT L'ACTION DES FLUCTUATIONS DES PETITES ECHELLES COMME UN BRUIT BLANC GAUSSIEN DE FAIBLE LARGEUR, NOUS MENONS A BIEN UNE ANALYSE SEMI-CLASSIQUE DE L'EQUATION STOCHASTIQUE AINSI OBTENUE, AU MOYEN D'UN ALGORITHME ORIGINAL. LES SOLUTIONS SINGULIERES ET AUTO-SIMILAIRES REPRODUISENT LA MULTIFRACTALITE DU PROBLEME DE DEPART, AINSI QUE LA FORME DE LA DISTRIBUTION DE PROBABILITE ASSOCIEE AUX OBJETS COHERENTS ET UN ACCORD QUANTITATIF EST ATTEINT POUR UN DOMAINE DE COUCHES PROCHES DE CELLE OU LA DISSIPATION EQUILIBRE LES EFFETS-NON LINEAIRES. NOUS APPROFONDISSONS NOTRE COMPREHENSION DES MECANISMES CONDUISANT A L'INTERMITTENCE EN MODELISANT LA HIERARCHIE DES PHENOMENES DE DUPLICATION DES PICS D'ACTIVITE EN DEGAGEANT UNE STRUCTURE EFFECTIVE D'ARBRE DANS L'ESPACE DES ECHELLES ET DES TEMPS, COMPATIBLE AVEC LES STATISTIQUES DU MODELE GOY. ENFIN NOUS GENERALISONS NOTRE PREMIERE APPROCHE AU PROBLEME DE L'ADVECTION D'UN SCALAIRE PASSIF PAR UN CHAMP DE VITESSE STOCHASTIQUE. PAR COMPARAISON AVEC LES SIMULATIONS NUMERIQUES DIRECTES, NOUS MONTRONS QUE LES STRUCTURES QUE NOUS AVONS IDENTIFIEES GOUVERNENT LE COMPORTEMENT EN LOIS D'ECHELLE DES MOMENTS D'ORDRE ELEVE DU SCALAIRE.
Download or read book Turbulence written by Uriel Frisch and published by Cambridge University Press. This book was released on 1995-11-30 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook presents a modern account of turbulence, one of the greatest challenges in physics. The state-of-the-art is put into historical perspective five centuries after the first studies of Leonardo and half a century after the first attempt by A. N. Kolmogorov to predict the properties of flow at very high Reynolds numbers. Such 'fully developed turbulence' is ubiquitous in both cosmical and natural environments, in engineering applications and in everyday life. The intended readership for the book ranges from first-year graduate students in mathematics, physics, astrophysics, geosciences and engineering, to professional scientists and engineers. Elementary presentations of dynamical systems ideas, of probabilistic methods (including the theory of large deviations) and of fractal geometry make this a self-contained textbook.
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 Flow Sensing in Air and Water written by Horst Bleckmann and published by Springer Science & Business Media. This book was released on 2014-01-22 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, leading scientists in the fields of sensory biology, neuroscience, physics and engineering explore the basic operational principles and behavioral uses of flow sensing in animals and how they might be applied to engineering applications such as autonomous control of underwater or aerial vehicles. Although humans possess no flow-sensing abilities, countless aquatic (e.g. fish, cephalopods and seals), terrestrial (e.g. crickets and spiders) and aerial (e.g. bats) animals have flow sensing abilities that underlie remarkable behavioral feats. These include the ability to follow silent hydrodynamic trails long after the trailblazer has left the scene, to form hydrodynamic images of their environment in total darkness, and to swim or fly efficiently and effortlessly in the face of destabilizing currents and winds.

Book excerpt: Chaos theory is giving scientists fresh insights into all sorts of unruly phenomena-from dripping faucets to swinging pendulums, from the vagaries of the weather to the movements of the planets, from heart rhythms to gold futures. In this collection of front-line reports, edited for the general reader, internationally recognized experts such as Ian Stewart, Robert M. May, and Benoit Mandelbrot draw on the latest research to trace the roots of chaos in modern science and mathematics.
