This book was released on 2021-04-02 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce deuxième ouvrage approfondit les concepts introduits dans le tome 1. L’accent est notamment porté sur le cas des géométries complexes utilisant des maillages non-orthogonaux ou non structurés. La discrétisation complète par la méthode des volumes finis d’une équation de transport générique est détaillée pour ce type de maillages. Lorsque l’équation de transport est hyperbolique, la mise en œuvre des schémas TVD est présentée. Dans le cadre de la résolution des équations de Navier-Stokes incompressibles, nous présentons les algorithmes de couplage vitesse-pression les plus utilisés : SIMPLE, SIMPLER, SIMPLEC, PISO, différentes méthodes de Projection et la méthode du lagrangien augmenté [MLA]. Cet ouvrage aborde aussi la résolution des équations de Navier-Stokes compressibles par une approche Pressure based solver [PBS] en généralisant l’algorithme de couplage vitesse-pression SIMPLE dans un contexte compressible. Ce tome 2 aborde aussi de nouvelles notions comme la résolution des équations de Navier-Stokes incompressibles en formulation vorticité-fonction de courant, la résolution des écoulements axisymétriques, la gestion des maillages multiblocs et les méthodes multigrilles pour la résolution des systèmes linéaires. Ce tome 2 s’achève avec des notions cruciales en CFD sur le contrôle des erreurs et des incertitudes ainsi que la vérification et la validation de la solution numérique. Un accent particulier est porté sur l’importance des bonnes pratiques à suivre en CFD lors de la résolution d’un problème.

Download or read book The Finite Volume Method in Computational Fluid Dynamics written by F. Moukalled and published by Springer. This book was released on 2015-08-13 with total page 799 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook explores both the theoretical foundation of the Finite Volume Method (FVM) and its applications in Computational Fluid Dynamics (CFD). Readers will discover a thorough explanation of the FVM numerics and algorithms used for the simulation of incompressible and compressible fluid flows, along with a detailed examination of the components needed for the development of a collocated unstructured pressure-based CFD solver. Two particular CFD codes are explored. The first is uFVM, a three-dimensional unstructured pressure-based finite volume academic CFD code, implemented within Matlab. The second is OpenFOAM®, an open source framework used in the development of a range of CFD programs for the simulation of industrial scale flow problems. With over 220 figures, numerous examples and more than one hundred exercise on FVM numerics, programming, and applications, this textbook is suitable for use in an introductory course on the FVM, in an advanced course on numerics, and as a reference for CFD programmers and researchers.

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.

Book excerpt: Ready access to computers has de?ned a new era in teaching and learning. The opportunity to extend the subject matter of traditional science and engineering curricula into the realm of scienti?c computing has become not only desirable, but also necessary. Thanks to portability and low overhead and operating cost, experimentation by numerical simulation has become a viable substitute, and occasionally the only alternative, to physical experimentation. The new framework has necessitated the writing of texts and monographs from a modern perspective that incorporates numerical and computer progr- ming aspects as an integral part of the discourse. Under this modern directive, methods, concepts, and ideas are presented in a uni?ed fashion that motivates and underlines the urgency of the new elements, but neither compromises nor oversimpli?es the rigor of the classical approach. Interfacing fundamental concepts and practical methods of scienti?c c- puting can be implemented on di?erent levels. In one approach, theory and implementation are kept complementary and presented in a sequential fashion. In another approach, the coupling involves deriving computational methods and simulation algorithms, and translating equations into computer code - structions immediately following problem formulations. Seamlessly interjecting methods of scienti?c computing in the traditional discourse o?ers a powerful venue for developing analytical skills and obtaining physical insight.

Available in PDF, EPUB and Kindle. Book excerpt: Covered from the vantage point of a user of a commercial flow package, Essentials of Computational Fluid Dynamics provides the information needed to competently operate a commercial flow solver. This book provides a physical description of fluid flow, outlines the strengths and weaknesses of computational fluid dynamics (CFD), presents the basics of the discretization of the equations, focuses on the understanding of how the flow physics interact with a typical finite-volume discretization, and highlights the approximate nature of CFD. It emphasizes how the physical concepts (mass conservation or momentum balance) are reflected in the CFD solutions while minimizing the required mathematical/numerical background. In addition, it uses cases studies in mechanical/aero and biomedical engineering, includes MATLAB and spreadsheet examples, codes and exercise questions. The book also provides practical demonstrations on core principles and key behaviors and incorporates a wide range of colorful examples of CFD simulations in various fields of engineering.
