Book excerpt: L'objectif principal de cette etude est d'examiner l'influence du caractere rheofluidifiant d'un fluide complexe sur les conditions de stabilite d'un ecoulement de Poiseuille plan. Le modele rheologique purement visqueux de Carreau est utilise. Apres une analyse lineaire de stabilite par une approche modale, dont les resultats ont clairement mis en evidence l'effet stabilisant de la stratification de la viscosite, une analyse faiblement non lineaire de stabilite a ete menee en vue d'examiner l'influence de la non-linearite du modele rheologique sur la stabilite vis-a-vis de perturbations d'amplitude finie. Des resultats originaux ont ete obtenus et montrent notamment que, contrairement aux termes d'inertie, les termes non lineaires visqueux ont tendance a accelerer l'ecoulement et favoriser une bifurcation sur-critique. Finalement, une analyse fortement non lineaire de stabilite a ete conduite en utilisant les techniques de suivi de branches de solutions par des methodes de continuation. Des solutions non lineaires d'equilibre sous-critique ont ete obtenues et caracterisees pour differentes valeurs des parametres rheologiques.
Book Synopsis PanVascular Medicine by : Peter Lanzer
Download or read book PanVascular Medicine written by Peter Lanzer and published by Springer. This book was released on 2015-03-30 with total page 5004 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vascular management and care has become a truly multidisciplinary enterprise as the number of specialists involved in the treatment of patients with vascular diseases has steadily increased. While in the past, treatments were delivered by individual specialists, in the twenty-first century a team approach is without doubt the most effective strategy. In order to promote professional excellence in this dynamic and rapidly evolving field, a shared knowledge base and interdisciplinary standards need to be established. Pan Vascular Medicine, 2nd edition has been designed to offer such an interdisciplinary platform, providing vascular specialists with state-of-the art descriptive and procedural knowledge. Basic science, diagnostics, and therapy are all comprehensively covered. In a series of succinct, clearly written chapters, renowned specialists introduce and comment on the current international guidelines and present up-to-date reviews of all aspects of vascular care.

Book Synopsis Advances in Mathematical Fluid Mechanics by : Rolf Rannacher
Download or read book Advances in Mathematical Fluid Mechanics written by Rolf Rannacher and published by Springer Science & Business Media. This book was released on 2010-03-17 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume celebrates the 60th birthday of Professor Giovanni Paolo Galdi and honors his remarkable contributions to research in the ?eld of Mathematical Fluid Mechanics. The book contains a collection of 35 peer reviewed papers, with authors from 20 countries, re?ecting the worldwide impact and great inspiration by his work over the years. These papers were selected from invited lectures and contributed talks presented at the International Conference on Mathematical Fluid Mechanics held in Estoril, Portugal, May 21–25, 2007 and organized on the oc- sion of Professor Galdi’s 60th birthday. We express our gratitude to all the authors and reviewers for their important contributions. Professor Galdi devotes his career to research on the mathematical analysis of the Navier-Stokes equations and non-Newtonian ?ow problems, with special emphasis on hydrodynamic stability and ?uid-particle interactions, impressing the worldwide mathematical communities with his results. His numerous contributions have laid down signi?cant milestones in these ?elds, with a great in?uence on interdis- plinary research communities. He has advanced the careers of numerous young researchers through his generosity and encouragement, some directly through int- lectual guidance and others indirectly by pairing them with well chosen senior c- laborators. A brief review of Professor Galdi’s activities and some impressions by colleagues and friends are included here.

Book Synopsis Modeling of Physiological Flows by : Davide Ambrosi
Download or read book Modeling of Physiological Flows written by Davide Ambrosi and published by Springer Science & Business Media. This book was released on 2012-10-31 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a mathematical update of the state of the art of the research in the field of mathematical and numerical models of the circulatory system. It is structured into different chapters, written by outstanding experts in the field. Many fundamental issues are considered, such as: the mathematical representation of vascular geometries extracted from medical images, modelling blood rheology and the complex multilayer structure of the vascular tissue, and its possible pathologies, the mechanical and chemical interaction between blood and vascular walls, and the different scales coupling local and systemic dynamics. All of these topics introduce challenging mathematical and numerical problems, demanding for advanced analysis and efficient simulation techniques, and pay constant attention to applications of relevant clinical interest. This book is addressed to graduate students and researchers in the field of bioengineering, applied mathematics and medicine, wishing to engage themselves in the fascinating task of modeling the cardiovascular system or, more broadly, physiological flows.

This book was released on 2013-09-27 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: La mécanique des fluides est abordée sous deux points de vue, physique et mathématique. Les bases de la mécanique des milieux continus sont d'abord présentées en détail en précisant les hypothèses et approximations qui conduisent aux lois de conservation. Les outils d'analyse des équations générales, étude en ordres de grandeurs, analyse adimensionnelle et similitude, permettent ensuite d'introduire les approximations de fluide parfait d'Euler, de fluides visqueux en régime de Stokes et de la couche limite de Prandtl. Les notions de stabilité des écoulements, de turbulence et les écoulements compressibles sont ensuite présentés. Les écoulements multiphysiques ouvrent des perspectives pour la recherche et le traitement d'applications complexes. In this book, fluid mechanics is addressed from both physical and mathematical perspectives. As a first step, the basic theory of continuum mechanics is detailed, pointing out the different assumptions and approximations that lead to conservation laws. As a second step, scaling studies, dimensional analysis and similitude of the general equations help to introduce the inviscid Euler fluid approximation, the Stokes approximation of viscous flow and Prandtl’s boundary layer approximation. Lastly, the concepts of stability, turbulence and compressible flows are presented. Multiphysics approach of flows will provide readers with deeper insights into basic and applied research on complex processing.
