This book was released on 2002 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail est consacré à l'étude et à la mise en oeuvre de la méthode des vortex aléatoires (Random Vortex Method (RVM)) qui permet de simuler des écoulements turbulents, bidimensionnels, incompressibles et instationnaires. L'algorithme de cette méthode et les conditions d'adhérence sont décrits. Deux types d'écoulements sont simulés. Le premier est l'écoulement de Couette-Poiseuille; le deuxième un écoulement pulsé autour d'une plaque plane (couche limite pulsée). Cette étude a permis de tester la RVM pour les deux types d'écoulements. Pour l'écoulement de Couette-Poiseuille, nous avons calculé le profil de vitesse moyenne ainsi que les grandeurs statistiques concernant les fluctuations de vitesses, et nous avons mis en évidence les structures cohérentes. Pour l'écoulement pulsé autour d'une plaque plane, des simulations sont réalisées pour une gamme de nombre de Reynolds (10[puissance]3-7.10[puissance]6). Une étude préliminaire expérimentale a été réalisée pour un écoulement pulsé autour d'une plaque plane afin de valider certains résultats numériques. Nous constatons un bon accord entre la simulation numérique et l'expérimentation.

Book Synopsis IUTAM Symposium on Variable Density Low-Speed Turbulent Flows by : Louis Fulachier
Download or read book IUTAM Symposium on Variable Density Low-Speed Turbulent Flows written by Louis Fulachier and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The General Assembly of the International Union of Theoretical and Applied Mechanics in its meeting on August 28, 1994, selected for 1996 only four Mechanics Symposia, of which ours is the only one related to Fluid Mechanics: Variable Density Low Speed Turbulent Flows. This IUTAM Symposium, organized by the Institut de Recherche sur les Phenomenes Hors Equilibre (Marseille), is the logical continuation of the meetings previously organized or co-organized - on the French or European level, such as Euromech 237, Marseille, 1988 - by the same research group ofMarseille. This meeting focused specifically on the structure of turbulent flows in which density varies strongly : the effect of this variation on the velocity and scalar fields is in no sense negligible. We were mainly concerned with low-speed flows subjected to strong local changes of density as a consequence of heat or mass transfer or of chemical reactions. Compressible turbulent flows - such a!" supersonic ones - were also considered in order to underline their similarities to and their differences from low-speed variable density flows.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of extended papers based on presentations given during the SIMHYDRO 2014 conference, held in Sophia Antipolis in June 2014. It focuses on the modeling and simulation of fast hydraulic transients, on 3D modeling, and on uncertainties and multiphase flows. The book explores both the limitations and performance of current models and presents the latest developments based on new numerical schemes, high-performance computing, multiphysics and multiscale methods, and better interaction with field or scale model data. It addresses the interests of practitioners, stakeholders, researchers and engineers active in this field.

Download or read book Biomimicry written by Janine M. Benyus and published by Harper Collins. This book was released on 2009-08-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.

Book Synopsis Vortex Dominated Flows by : Denis L. Blackmore
Download or read book Vortex Dominated Flows written by Denis L. Blackmore and published by World Scientific. This book was released on 2005 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honoring the contributions of one of the field's leading experts, Lu Ting, this indispensable volume contains important new results at the cutting edge of research. A wide variety of significant new analytical and numerical results in critical areas are presented, including point vortex dynamics, superconductor vortices, cavity flows, vortex breakdown, shock/vortex interaction, wake flows, magneto-hydrodynamics, rotary wake flows, and hypersonic vortex phenomena.The book will be invaluable for those interested in the state of the art of vortex dominated flows, both from a theoretical and applied perspective.Professor Lu Ting and Joe Keller have worked together for over 40 years. In their first joint work entitled ?Periodic vibrations of systems governed by nonlinear partial differential equations?, perturbation analysis and bifurcation theory were used to determine the frequencies and modes of vibration of various physical systems. The novelty was the application to partial differential equations of methods which, previously, had been used almost exclusively on ordinary differential equations. Professsor Lu Ting is an expert in both fluid dynamics and the use of matched asymptotic expansions. His physical insight into fluid flows has led the way to finding the appropriate mathematical simplications used in the solutions to many difficult flow problems.
