DANS LA SIMULATION DE LA MECANIQUE DES FLUIDES, LES EFFETS DE LA DIFFUSION DANS LE FLUIDE SONT FAIBLES DANS UNE PARTIE DE LA REGION DE CALCUL. LES EQUATIONS SONT PLUS SIMPLES ET AUSSI MOINS COUTEUSES A APPROCHER QUE LES EQUATIONS DE NAVIER-STOKES. LA PREMIERE PARTIE DE CE TRAVAIL EST CONSACREE A LA RESOLUTION DES EQUATIONS D'EULER EN DEUX DIMENSIONS D'ESPACE POUR LEQUEL ON INTRODUIT UNE METHODE DE DECOUPLAGE VITESSE/TOURBILLON. DEUX METHODES DE DISCRETISATION SPECTRALES, DE TYPE GALERKIN ET COLLOCATION, SONT UTILISEES POUR APPROCHER LES EQUATIONS AINSI DECOUPLEES. ON MONTRE DES RESULTATS DE STABILITE ET DES ESTIMATIONS D'ERREUR POUR CHACUNE DE CES DISCRETISATIONS. DES COURBES D'ERREUR CONFIRMENT LES RESULTATS THEORIQUES AINSI OBTENUS. DANS LA DEUXIEME PARTIE ON S'INTERESSE A L'ETUDE DU PROBLEME DE COUPLAGE ENTRE LES EQUATIONS DE NAVIER-STOKES ET D'EULER PAR DES METHODES DE TYPE ELEMENTS SPECTRAUX OU LES CONDITIONS DE RACCORD APPROPRIEES SONT SPECIFIEES. CETTE METHODE DE COUPLAGE EST VALIDEE PAR DES SIMULATIONS NUMERIQUES DU MOUVEMENT D'UN FLUIDE AUTOUR D'UN OBSTACLE. NOUS MONTRONS QUE L'APPROCHE MISE EN UVRE EST STABLE, ET FOURNIT UNE ALTERNATIVE MOINS COUTEUSE QU'UN CODE SPECTRAL NAVIER-STOKES PUR

This introductory physical and mathematical presentation of the Navier-Stokes equations focuses on unresolved questions of the regularity of solutions in three spatial dimensions, and the relation of these issues to the physical phenomenon of turbulent fluid motion.

This volume collects the articles presented at the Third International Conference on “The Navier-Stokes Equations: Theory and Numerical Methods”, held in Oberwolfach, Germany. The articles are important contributions to a wide variety of topics in the Navier-Stokes theory: general boundary conditions, flow exterior to an obstacle, conical boundary points, the controllability of solutions, compressible flow, non-Newtonian flow, magneto-hydrodynamics, thermal convection, the interaction of fluids with elastic solids, the regularity of solutions, and Rothe's method of approximation.

Originally published in 1977, the book is devoted to the theory and numerical analysis of the Navier-Stokes equations for viscous incompressible fluid. On the theoretical side, results related to the existence, the uniqueness, and, in some cases, the regularity of solutions are presented. On the numerical side, various approaches to the approximation of Navier-Stokes problems by discretization are considered, such as the finite dereference method, the finite element method, and the fractional steps method. The problems of stability and convergence for numerical methods are treated as completely as possible. The new material in the present book (as compared to the preceding 1984 edition) is an appendix reproducing a survey article written in 1998. This appendix touches upon a few aspects not addressed in the earlier editions, in particular a short derivation of the Navier-Stokes equations from the basic conservation principles in continuum mechanics, further historical perspectives, and indications on new developments in the area. The appendix also surveys some aspects of the related Euler equations and the compressible Navier-Stokes equations. The book is written in the style of a textbook and the author has attempted to make the treatment self-contained. It can be used as a textbook or a reference book for researchers. Prerequisites for reading the book include some familiarity with the Navier-Stokes equations and some knowledge of functional analysis and Sololev spaces.

The present book consists of three parts. In the first part a theory of solvability for the stationary Stokes equations in exterior domains is developed. We prove existence of strong solutions in Sobolev spaces and use a localisation principle and the divergence equation to deduce further properties of the solution (uniqueness, asymptotics).

The Navier-Stokes equations describe the motion of fluids and are an invaluable addition to the toolbox of every physicist, applied mathematician, and engineer. The equations arise from applying Newton's laws of motion to a moving fluid and are considered, when used in combination with mass and energy conservation rules, to be the fundamental governing equations of fluid motion. They are relevant across many disciplines, from astrophysics and oceanic sciences to aerospace engineering and materials science. This Student's Guide provides a clear and focused presentation of the derivation, significance and applications of the Navier-Stokes equations, along with the associated continuity and energy equations. Designed as a useful supplementary resource for undergraduate and graduate students, each chapter concludes with a selection of exercises intended to reinforce and extend important concepts. Video podcasts demonstrating the solutions in full are provided online, along with written solutions and other additional resources.
