Download or read book Simulation numérique en mécanique des fluides. 2e édition written by Philippe Traoré and published by Éditions Cépaduès. This book was released on 2022-08-10 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’objectif de cet ouvrage est de décrire les fondements théoriques de la méthode des volumes finis qui est aujourd’hui reconnue, à bien des égards, comme étant la méthode de choix pour la simulation numérique en mécanique des fluides. Il s’adresse principalement aux étudiants de master ou d’écoles d’ingénieurs qui souhaitent s’initier aux principes de la simulation numérique en mécanique des fluides basée sur la méthode des volumes finis. Après une introduction sur l’essor et les enjeux de la simulation numérique, les équations de conservation en mécanique des fluides sont rappelées. L’ouvrage introduit ensuite les concepts de base de la méthode des volumes finis et aborde la notion de maillage (maillage structuré, multibloc, non-structuré, non-conforme,…). L’équation de transport d’une quantité scalaire est utilisée comme équation modèle et la discrétisation de chacun de ses termes (terme temporel, terme diffusif, terme convectif et terme source ou puits) est détaillée. Une attention particulière est portée sur les notions fondamentales comme l’ordre de précision, la stabilité et la convergence des schémas numériques. La discrétisation des équations de Navier-Stokes incompressibles en variables primitives est ensuite abordée en détail. Un chapitre spécifique est consacré à l’implémentation des différents types de conditions aux limites. Ce Tome 1, résolument axé sur la mise en œuvre pratique de la méthode des volumes finis dans des géométries simples, est une introduction très didactique qui ouvrira le lecteur à des concepts plus avancés développés dans le Tome 2.

Download or read book Simulation Numérique en Mécanique Des Fluides written by Lionel Helin and published by Editions Universitaires Europeennes. This book was released on 2010-05 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le developpement de modeles algebriques pour les fluides viscoelastiques vise a simplifier les formulations des modeles differentiels usuels dans un souci de reduction des couts de calculs. Alors que les modeles differentiels requierent la resolution d'une equation aux derivees partielles par composante de tension, les modeles algebriques reposent sur la resolution d'une unique equation de transport pour la trace du tenseur viscoelastique et sur des expressions explicites simples pour les tensions. Dans ce travail, deux nouvelles formulations de modeles algebriques reproduisant les proprietes de cisaillement pur du modele differentiel d'Oldroyd-B sont proposees. Ces modeles sont mis en oeuvre sur des geometries 2D variees: ecoulement dans une contraction 4:1, autour d'un cylindre et dans une conduite courbee a 180 . Ces simulations ont ete menees au moyen d'un code volumes finis ecrit en coordonnees orthogonales generalisees. On prouve que les modeles algebriques simplifies reproduisent avec un cout de calcul nettement reduit les proprietes du modele differentiel d'Oldroyd-B, a condition de respecter l'indifference materielle des nouvelles formulations proposees."
Book Synopsis Fluid-Structure Interactions and Uncertainties by : Abdelkhalak El Hami
Download or read book Fluid-Structure Interactions and Uncertainties written by Abdelkhalak El Hami and published by John Wiley & Sons. This book was released on 2017-02-08 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the general study of fluid structure interaction with consideration of uncertainties. The fluid-structure interaction is the study of the behavior of a solid in contact with a fluid, the response can be strongly affected by the action of the fluid. These phenomena are common and are sometimes the cause of the operation of certain systems, or otherwise manifest malfunction. The vibrations affect the integrity of structures and must be predicted to prevent accelerated wear of the system by material fatigue or even its destruction when the vibrations exceed a certain threshold.

Book Synopsis Advances in Fluid-Structure Interaction by : Marianna Braza
Download or read book Advances in Fluid-Structure Interaction written by Marianna Braza and published by Springer. This book was released on 2016-04-07 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses flow separation within the context of fluid-structure interaction phenomena. Here, new findings from two research communities focusing on fluids and structures are brought together, emphasizing the importance of a unified multidisciplinary approach. The book covers the theory, experimental findings, numerical simulations, and modeling in fluid dynamics and structural mechanics for both incompressible and compressible separated unsteady flows. There is a focus on the morphing of lifting structures in order to increase their aerodynamic and/or hydrodynamic performances, to control separation and to reduce noise, as well as to inspire the design of novel structures. The different chapters are based on contributions presented at the ERCOFTAC Symposium on Unsteady Separation in Fluid-Structure Interaction held in Mykonos, Greece, 17-21 June, 2013 and include extended discussions and new highlights. The book is intended for students, researchers and practitioners in the broad field of computational fluid dynamics and computational structural mechanics. It aims at supporting them while dealing with practical issues, such as developing control strategies for unsteady separation and applying smart materials and biomimetic approaches for design and control.

Download or read book Fluid-Structure Interactions written by Michael P. Paidoussis and published by Academic Press. This book was released on 2013-12-07 with total page 885 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first of two books concentrating on the dynamics of slender bodies within or containing axial flow, Fluid-Structure Interaction, Volume 1 covers the fundamentals and mechanisms giving rise to flow-induced vibration, with a particular focus on the challenges associated with pipes conveying fluid. This volume has been thoroughly updated to reference the latest developments in the field, with a continued emphasis on the understanding of dynamical behaviour and analytical methods needed to provide long-term solutions and validate the latest computational methods and codes. In this edition, Chapter 7 from Volume 2 has also been moved to Volume 1, meaning that Volume 1 now mainly treats the dynamics of systems subjected to internal flow, whereas in Volume 2 the axial flow is in most cases external to the flow or annular. - Provides an in-depth review of an extensive range of fluid-structure interaction topics, with detailed real-world examples and thorough referencing throughout for additional detail - Organized by structure and problem type, allowing you to dip into the sections that are relevant to the particular problem you are facing, with numerous appendices containing the equations relevant to specific problems - Supports development of long-term solutions by focusing on the fundamentals and mechanisms needed to understand underlying causes and operating conditions under which apparent solutions might not prove effective

Book Synopsis Interaction fluide-structure by : Jean-François Sigrist
Download or read book Interaction fluide-structure written by Jean-François Sigrist and published by Ellipses Marketing. This book was released on 2011 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ouvrage présente les méthodes d'éléments finis pour l'analyse vibratoire de systèmes mécaniques avec prise en compte des interactions fluide/structure. Il rappelle les bases mathématiques de modélisation de ces problèmes dans l'hypothèse de fluide stagnant et il expose les principes de discrétisation éléments finis. Il détaille en particulier les différentes formulations couplées, lesquelles peuvent prendre en compte les effets de compressibilité et de gravité dans le comportement du fluide. Les notions spécifiques à l'analyse vibratoire des systèmes sont revisitées dans ce contexte. Le livre est constitué de cinq chapitres. Après une introduction générale à la problématique de l'interaction fluide/structure (chapitre I), les méthodes éléments finis structure et fluide sont détaillées séparément (chapitres II et III), avant de s'intéresser au couplage d'éléments finis (chapitre IV) et aux méthodes d'analyse vibratoire de systèmes couplés (chapitre V). De nombreux exemples d'application permettent le développement de solutions analytiques qui sont confrontées aux résultats du calcul numérique par éléments finis. Adoptant un point de vue à la fois théorique et pratique, le propos d'ensemble est résolument pédagogique. L'ouvrage constitue ainsi une base solide d'appropriation des méthodes éléments finis en interaction fluide/structure.

This book was released on 2012-12-06 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: This plenary paper and the accompanying presentation have highlighted field problems involving fluid-structure interaction over a wide span of Navy operations. Considering the vast size and versatility of the Navy's inventory, the cases presented represent examples of a much larger problem. But even this limited set provides sufficient evidence that fluid-structure interaction does hinder the Navy's ability to accomplish its missions. This survey has also established that there are no accurate and generally applicable design tools for addressing these problems. In the majority of cases the state-of-practice is to either make ad-hoc adjustments and estimates based on historical evidence, or conduct expensive focused tests directed at each specific problem and/or candidate solution. Unfortunately, these approaches do not provide insight into the fundamental problem, and neither can be considered reliable regarding their likelihood of success. So the opportunities for applying computational fluid-structure interaction modeling to Navy problems appear limitless. Scenarios range from the "simple" resonant strumming of underwater and in-air cables, to the "self-contained" flow field and vibration of aircraft/ordnance bodies at various Mach numbers, to violent underwater transient detonations and local hull structural collapse. Generally applicable and computationally tractable design-oriented models for these phenomena are of course still far in the future. But the Navy has taken the first steps in that direction by sponsoring specialized numerical models, validation experiments tailored for specific applications, and conferences such as this one.
