This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Les travaux présentés dans ce manuscrit ont pour objet l'étude de méthodes de préconditionnement efficaces pour des problèmes elliptiques en géométrie non orthogonale traités par méthode de type pseudo spectrale, et leur utilisation afin de simuler de manière précise et efficace l'écoulement de fluide visqueux incompressible en cavité bidimensionnelle déformée. Une première partie est ainsi consacrée à l'étude du préconditionnement des équations elliptiques mono et bidimensionnelles pour une discrétisation basée sur une série de polynômes de Fourier ou de Chebychev. Parmi les trois méthodes de précision finie envisagées comme préconditionneur, différences finies (DF), éléments finis (EF), et volumes finis (VF), nous montrons que les VF représentent le meilleur préconditionneur d'ordre faible. Le préconditionnement VF est ensuite mis en œuvre avec succès pour le développement d'un solveur pseudo spectral des équations de Navier Stokes, en géométrie non orthogonale. Le découplage des champs de vitesse et pression est basé sur l'algorithme de « Projection Diffusion ». Une seconde partie de ce travail est consacrée à l'étude d'écoulements incompressibles en géométries non orthogonales, le solveur développé permettant l'accès à des solutions numériques à précision spectrale. Pour l'écoulement en cavité entraînée déformée bidimensionnelle, nous montrons la sensibilité de la topologie de l'écoulement et de sa stabilité, vis-à-vis de la déformation
Book Synopsis Contribution à la simulation numérique d'écoulements incompressibles en géométries complexes by : Kwalha Ahipo

This book was released on 2007 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail a pour objet le développement d'un code de calcul pour la résolution numérique des équations de Navier-Stokes en écoulement incompressible dans des domaines géométriques quelconques. Les équations sont discrétisées selon la technique des volumes finis sur un maillage cartésien non orthogonal, colocalisé (sans décalage de grille de calcul des composantes de vitesse et de la pression). La non orthogonalité des volumes de contrôle est prise en compte à l'aide de schémas numériques spécifiques inspirés des travaux de M. Péric (Defered Correction). Le couplage vitesse-pression est régi par un algorithme prédicteur-correcteur basé sur la Méthode de Projection, utilisant la décomposition de Hodge, qui semble plus performant que les algorithmes classiques de type SIMPLE (Semi-Implicit Method for Pressure-Linked Equation). Cet algorithme intègre les approximations de Rhie et Chow qui permettent de limiter les oscillations numériques inhérentes à l'utilisation d'un maillage colocalisé. Les divers éléments introduits lors de l'élaboration du code en vue d'accroître ses performances ont été systématiquement évalués et comparés sur des écoulements tests en géométrie 2D. Finalement ce code a pu être utilisé pour modéliser l'écoulement 3D d'un jet de paroi au-dessus d'une bosse. Une étude comparative montre que les résultats de la simulation sont nettement meilleurs que ceux obtenus dans les mêmes conditions par une approche de type frontière immergée utilisant un simple maillage cartésien orthogonal.
Book Synopsis Vortex Flows and Related Numerical Methods by : J.T. Beale
Download or read book Vortex Flows and Related Numerical Methods written by J.T. Beale and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many important phenomena in fluid motion are evident in vortex flow, i.e., flows in which vortical structures are significant in determining the whole flow. This book, which consists of lectures given at a NATO ARW held in Grenoble (France) in June 1992, provides an up-to-date account of current research in the study of these phenomena by means of numerical methods and mathematical modelling. Such methods include Eulerian methods (finite difference, spectral and wavelet methods) as well as Lagrangian methods (contour dynamics, vortex methods) and are used to study such topics as 2- or 3-dimensional turbulence, vorticity generation by solid bodies, shear layers and vortex sheets, and vortex reconnection. For researchers and graduate students in computational fluid dynamics, numerical analysis, and applied mathematics.

Book Synopsis Advances in Turbulence VII by : Uriel Frisch
Download or read book Advances in Turbulence VII written by Uriel Frisch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Turbulence VII contains an overview of the state of turbulence research with some bias towards work done in Europe. It represents an almost complete collection of the invited and contributed papers delivered at the Seventh European Turbulence Conference, sponsored by EUROMECH and ERCOFTAC and organized by the Observatoire de la Côte d'Azur. New high-Reynolds number experiments combined with new techniques of imaging, non-intrusive probing, processing and simulation provide high-quality data which put significant constraints on possible theories. For the first time, it has been shown, for a class of passive scalar problems, why dimensional analysis sometimes gives the wrong answers and how anomalous intermittency corrections can be calculated from first principles. The volume is thus geared towards specialists in the area of flow turbulence who could not attend the conference as well as anybody interested in this rapidly moving field.
Book Synopsis Space, Structure and Randomness by : Michel Bilodeau
Download or read book Space, Structure and Randomness written by Michel Bilodeau and published by Springer Science & Business Media. This book was released on 2007-12-23 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space, structure, and randomness: these are the three key concepts underlying Georges Matheron’s scientific work. He first encountered them at the beginning of his career when working as a mining engineer, and then they resurfaced in fields ranging from meteorology to microscopy. What could these radically different types of applications possibly have in common? First, in each one only a single realisation of the phenomenon is available for study, but its features repeat themselves in space; second, the sampling pattern is rarely regular, and finally there are problems of change of scale. This volume is divided in three sections on random sets, geostatistics and mathematical morphology. They reflect his professional interests and his search for underlying unity. Some readers may be surprised to find theoretical chapters mixed with applied ones. We have done this deliberately. GM always considered that the distinction between the theory and practice was purely academic. When GM tackled practical problems, he used his skill as a physicist to extract the salient features and to select variables which could be measured meaningfully and whose values could be estimated from the available data. Then he used his outstanding ability as a mathematician to solve the problems neatly and efficiently. It was his capacity to combine a physicist’s intuition with a mathematician’s analytical skills that allowed him to produce new and innovative solutions to difficult problems. The book should appeal to graduate students and researchers working in mathematics, probability, statistics, physics, spatial data analysis, and image analysis. In addition it will be of interest to those who enjoy discovering links between scientific disciplines that seem unrelated at first glance. In writing the book the contributors have tried to put GM’s ideas into perspective. During his working life, GM was a genuinely creative scientist. He developed innovative concepts whose usefulness goes far beyond the confines of the discipline for which they were originally designed. This is why his work remains as pertinent today as it was when it was first written.

Book Synopsis Flow Sensing in Air and Water by : Horst Bleckmann
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 Synopsis The Legacy of John von Neumann by : American Mathematical Society
Download or read book The Legacy of John von Neumann written by American Mathematical Society and published by American Mathematical Soc.. This book was released on 1990 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ideas of John von Neumann have had a profound influence on modern mathematics and science. One of the great thinkers of our century, von Neumann initiated major branches of mathematics--from operator algebras to game theory to scientific computing--and had a fundamental impact on such areas as self-adjoint operators, ergodic theory and the foundations of quantum mechanics, and numerical analysis and the design of the modern computer. This volume contains the proceedings of an AMS Symposium in Pure Mathematics, held at Hofstra University, in May 1988. The symposium brought together some of the foremost researchers in the wide range of areas in which von Neumann worked. These articles illustrate the sweep of von Neumann's ideas and thinking and document their influence on contemporary mathematics. In addition, some of those who knew von Neumann when he was alive have presented here personal reminiscences about him. This book is directed to those interested in operator theory, game theory, ergodic theory, and scientific computing, as well as to historians of mathematics and others having an interest in the contemporary history of the mathematical sciences. This book will give readers an appreciation for the workings of the mind of one of the mathematical giants of our time.
