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.

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.

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 Numerical Simulation of Oscillatory Convection in Low-Pr Fluids by : Bernard Roux
Download or read book Numerical Simulation of Oscillatory Convection in Low-Pr Fluids written by Bernard Roux and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last ten years, there has been an ever-increasing awareness that fluid motion and transport processes influenced by buoyancy are of interest in many fields of science and technology. In particular, a lot of research has been devoted to the oscillatory behaviour of metallic melts (low-Pr fluids) due to the very crucial impact of such flow oscillations on the quality of growing crystals, semi-conductors or metallic alloys, for advanced technology applications. Test cases on the 2D oscillatory convection in differentially heated cavities containing low-Pr fluids have been defined by the organizing committee, and proposed to the community in 1987. The GAMM-Worshop was attended by 55 scientists from 12 countries, in Oct. 1988 in Marseille (France). Twenty-eight groups contributed to the mandatory cases coming from France (12), other European countries (7) and other countries: USA, Japan and Australia (9). Several groups also presented solutions of various related problems such as accurate determination of the threshold for the onset of oscillations, thermocapillary effect in open cavities, and 3D simulations. Period doubling, quasi- periodic behaviour, reverse transition and hysteresis loops have been reported for high Grashof numbers in closed cavities. The workshop was also open to complementary contributions (5), from experiments and theory (stability and bifurcation analysis). The book contains details about the various methods employed and the specific results obtained by each contributor.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a practical guide to molecular dynamics and Monte Carlo simulation techniques used in the modelling of simple and complex liquids. Computer simulation is an essential tool in studying the chemistry and physics of condensed matter, complementing and reinforcing both experiment and theory. Simulations provide detailed information about structure and dynamics, essential to understand the many fluid systems that play a key role in our daily lives: polymers, gels, colloidal suspensions, liquid crystals, biological membranes, and glasses. The second edition of this pioneering book aims to explain how simulation programs work, how to use them, and how to interpret the results, with examples of the latest research in this rapidly evolving field. Accompanying programs in Fortran and Python provide practical, hands-on, illustrations of the ideas in the text.

Book Synopsis Direct and Large-Eddy Simulation I by : Peter R. Voke
Download or read book Direct and Large-Eddy Simulation I written by Peter R. Voke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a truism that turbulence is an unsolved problem, whether in scientific, engin eering or geophysical terms. It is strange that this remains largely the case even though we now know how to solve directly, with the help of sufficiently large and powerful computers, accurate approximations to the equations that govern tur bulent flows. The problem lies not with our numerical approximations but with the size of the computational task and the complexity of the solutions we gen erate, which match the complexity of real turbulence precisely in so far as the computations mimic the real flows. The fact that we can now solve some turbu lence in this limited sense is nevertheless an enormous step towards the goal of full understanding. Direct and large-eddy simulations are these numerical solutions of turbulence. They reproduce with remarkable fidelity the statistical, structural and dynamical properties of physical turbulent and transitional flows, though since the simula tions are necessarily time-dependent and three-dimensional they demand the most advanced computer resources at our disposal. The numerical techniques vary from accurate spectral methods and high-order finite differences to simple finite-volume algorithms derived on the principle of embedding fundamental conservation prop erties in the numerical operations. Genuine direct simulations resolve all the fluid motions fully, and require the highest practical accuracy in their numerical and temporal discretisation. Such simulations have the virtue of great fidelity when carried out carefully, and repre sent a most powerful tool for investigating the processes of transition to turbulence.
Book Synopsis Deep Learning for Fluid Simulation and Animation by : Gilson Antonio Giraldi
Download or read book Deep Learning for Fluid Simulation and Animation written by Gilson Antonio Giraldi and published by Springer Nature. This book was released on 2023 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to the use of machine learning and data-driven approaches in fluid simulation and animation, as an alternative to traditional modeling techniques based on partial differential equations and numerical methods – and at a lower computational cost. This work starts with a brief review of computability theory, aimed to convince the reader – more specifically, researchers of more traditional areas of mathematical modeling – about the power of neural computing in fluid animations. In these initial chapters, fluid modeling through Navier-Stokes equations and numerical methods are also discussed. The following chapters explore the advantages of the neural networks approach and show the building blocks of neural networks for fluid simulation. They cover aspects related to training data, data augmentation, and testing. The volume completes with two case studies, one involving Lagrangian simulation of fluids using convolutional neural networks and the other using Generative Adversarial Networks (GANs) approaches.

This book was released on 2012-12-06 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational fluid flow is not an easy subject. Not only is the mathematical representation of physico-chemical hydrodynamics complex, but the accurate numerical solution of the resulting equations has challenged many numerate scientists and engineers over the past two decades. The modelling of physical phenomena and testing of new numerical schemes has been aided in the last 10 years or so by a number of basic fluid flow programs (MAC, TEACH, 2-E-FIX, GENMIX, etc). However, in 1981 a program (perhaps more precisely, a software product) called PHOENICS was released that was then (and still remains) arguably, the most powerful computational tool in the whole area of endeavour surrounding fluid dynamics. The aim of PHOENICS is to provide a framework for the modelling of complex processes involving fluid flow, heat transfer and chemical reactions. PHOENICS has now been is use for four years by a wide range of users across the world. It was thus perceived as useful to provide a forum for PHOENICS users to share their experiences in trying to address a wide range of problems. So it was that the First International PHOENICS Users Conference was conceived and planned for September 1985. The location, at the Dartford Campus of Thames Polytechnic, in the event, proved to be an ideal site, encouraging substantial interaction between the participants.
