UNE METHODE D'ELEMENTS FINIS DISCONTINUS POUR LES EQUATIONS D'EULER DES FLUIDES COMPRESSIBLES
Author: LAHCEN.. KADDOURI
Publisher:
ISBN:
Category :
Languages : fr
Pages : 150
Book Description
L'OBJECTIF DE CETTE ETUDE EST DE RESOUDRE LES EQUATIONS D'EULER POUR LES FLUIDES COMPRESSIBLES A L'AIDE D'UNE METHODE D'ELEMENTS FINIS DISCONTINUS. CETTE METHODE S'APPLIQUE AUSSI BIEN SUR DES MAILLAGES STRUCTURES QUE NON STRUCTURES. LES EQUATIONS D'EULER SONT ECRITES EN FORMULATION CONSERVATIVE ET EN COORDONNEES EULERIENNES. LES VARIABLES CONSERVATIVES SONT APPROCHEES PAR DES FONCTIONS LINEAIRES OU BILINEAIRES DISCONTINUES PAR MORCEAUX. LA METHODE COMPORTE DEUX ETAPES DE CALCUL. LA PREMIERE ETAPE EST UNE ETAPE ELEMENTS FINIS, INCLUANT L'UTILISATION DE SOLVEURS DE RIEMANN MONODIMENSIONNELS. ON COMPARE DES SOLVEURS DE TYPE ROE AVEC DIFFERENTES CORRECTIONS ENTROPIQUES ET UN SOLVEUR DE TYPE OSHER. LA DEUXIEME ETAPE EST UNE ETAPE DE LIMITATION DE PENTE MULTIDIMENSIONNELLE EFFECTUEE SUR LES VARIABLES PHYSIQUES. ON ILLUSTRE LA METHODE EN CALCULANT LA SOLUTION DE DEUX PROBLEMES STATIONNAIRES, COMME SOLUTION LIMITE AUX TEMPS LONGS DU CAS INSTATIONNAIRE: CHOC REGULIER DU PROBLEME DE REFLEXION ET ECOULEMENT HYPERSONIQUE A NOMBRE DE MACH ELEVE AUTOUR D'UNE DOUBLE ELLIPSE. ON UTILISE SOIT UN SCHEMA EXPLICITE EN TEMPS RESPECTANT UNE CONDITION CFL, SOIT UN SCHEMA IMPLICITE LINEARISE QUI PERMET L'UTILISATION DE GRANDS PAS DE TEMPS. ENFIN UNE TECHNIQUE DE MAILLAGES ADAPTATIFS A ETE ADAPTEE A LA METHODE DES ELEMENTS FINIS DISCONTINUS. ELLE APPORTE DES GAINS EN TEMPS DE CALCUL IMPORTANTS

Computational Structural Mechanics & Fluid Dynamics
Author: A.K. Noor
Publisher: Elsevier
ISBN: 1483287041
Category : Technology & Engineering
Languages : en
Pages : 467
Book Description
Computational structural mechanics (CSM) and computational fluid dynamics (CFD) have emerged in the last two decades as new disciplines combining structural mechanics and fluid dynamics with approximation theory, numerical analysis and computer science. Their use has transformed much of theoretical mechanics and abstract science into practical and essential tools for a multitude of technological developments which affect many facets of our life. This collection of over 40 papers provides an authoritative documentation of major advances in both CSM and CFD, helping to identify future directions of development in these rapidly changing fields. Key areas covered are fluid structure interaction and aeroelasticity, CFD technology and reacting flows, micromechanics, stability and eigenproblems, probabilistic methods and chaotic dynamics, perturbation and spectral methods, element technology (finite volume, finite elements and boundary elements), adaptive methods, parallel processing machines and applications, and visualization, mesh generation and artificial intelligence interfaces.

Lectures on Numerical Methods for Non-Linear Variational Problems
Author: R. Glowinski
Publisher: Springer Science & Business Media
ISBN: 3540775064
Category : Mathematics
Languages : en
Pages : 507
Book Description
When Herb Keller suggested, more than two years ago, that we update our lectures held at the Tata Institute of Fundamental Research in 1977, and then have it published in the collection Springer Series in Computational Physics, we thought, at first, that it would be an easy task. Actually, we realized very quickly that it would be more complicated than what it seemed at first glance, for several reasons: 1. The first version of Numerical Methods for Nonlinear Variational Problems was, in fact, part of a set of monographs on numerical mat- matics published, in a short span of time, by the Tata Institute of Fun- mental Research in its well-known series Lectures on Mathematics and Physics; as might be expected, the first version systematically used the material of the above monographs, this being particularly true for Lectures on the Finite Element Method by P. G. Ciarlet and Lectures on Optimization—Theory and Algorithms by J. Cea. This second version had to be more self-contained. This necessity led to some minor additions in Chapters I-IV of the original version, and to the introduction of a chapter (namely, Chapter Y of this book) on relaxation methods, since these methods play an important role in various parts of this book.
