Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL CONCERNE LA RESOLUTION NUMERIQUE DES EQUATIONS DE NAVIER-STOKES POUR UN ECOULEMENT INCOMPRESSIBLE TURBULENT. POUR UN CHOIX DE COORDONNEES CURVILIGNES, LA THESE SE DIVISE EN DEUX PARTIES (PREMIERE PARTIE: FORMULATION CONVECTIVE; DEUXIEME PARTIE: FORMULATION CONSERVATIVE). LA FORMULATION CONVECTIVE EST TRAITEE PAR LE MODE PARTIELLEMENT PARABOLIQUE ET LE COUPLAGE VITESSE-PRESSION UTILISE UNE METHODE DE CORRECTION DE PRESSION (PROCEDURE SIMPLER). LE SOLVEUR DE PRESSION EMPLOI UN ALGORITHME DE GRADIENTS CONJUGUES PRECONDITIONNE PAR UN LU INCOMPLET OU LES INVERSIONS SONT REALISEES PAR DES SERIES DE NEUMANN A NOMBRE DE TERMES FINIE. DEUX APPLICATIONS SONT CONSIDEREES. L'UNE EST LE PROBLEME AXISYMETRIQUE DE L'INTERACTION HELICE-CARENE (EXPERIENCES DU DTRC) OU LE PROPULSEUR EST MODELISE PAR UNE THEORIE DE DISQUE ACTUATEUR. L'AUTRE (EXPERIENCES DU DLR) CORRESPOND A L'ECOULEMENT TURBULENT AUTOUR DE L'ELLIPSOIDE DE REVOLUTION A 10 DEGRES D'IUNCIDENCE (RE=7.2 MILLIONS). LES COMPARAISONS SONT EN ACCORD AVEC LES EXPERIENCES POUR LE PREMIER CAS ET METTENT EN EVIDENCE, DANS LE DEUXIEME CAS, LE BESOIN DE SE DEBARASSER DE CONDITIONS INITIALES ET LES PROBLEMES DE CONVERGENCE LIES A LA TECHNIQUE DE CORRECTION DE PRESSION. CELA JUSTIFIE LE DEVELOPPEMENT DE LA FORMULATION CONSERVATIVE. CETTE FORMULATION REPOSE SUR UN TRAITEMENT ELLIPTIQUE, LA TECHNIQUE DE CORRECTION DE PRESSION SUIT ALORS L'APPROCHE DE LA PROCEDURE PISO. LES CALCULS SONT MENES POUR L'ECOULEMENT LAMINAIRE COMPLET AUTOUR DE L'ELLIPSOIDE DE REVOLUTION A 10 DEGRES D'INCIDENCE (RE=1.6 MILLIONS). LES RESULTATS SONT MEILLEURS MALGRE UN MANQUE DE NOMBRE DE POINTS DE DISCRETISATION. CE TRAVAIL EVOQUE AUSSI (EN ANNEXES) LES PROBLEMES INHERENTS A LA DISCRETISATION DES EQUATIONS DE QUANTITE DE MOUVEMENT ET PROPOSE QUELQUES TECHNIQUES POUR AMELIORER LA QUALITE DES SCHEMAS NUMERIQUES
Book Synopsis Contributions to Current Challenges in Mathematical Fluid Mechanics by : Giovanni P. Galdi
Download or read book Contributions to Current Challenges in Mathematical Fluid Mechanics written by Giovanni P. Galdi and published by Springer Science & Business Media. This book was released on 2004-07-23 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume consists of five research articles, each dedicated to a significant topic in the mathematical theory of the Navier-Stokes equations, for compressible and incompressible fluids, and to related questions. All results given here are new and represent a noticeable contribution to the subject. One of the most famous predictions of the Kolmogorov theory of turbulence is the so-called Kolmogorov-obukhov five-thirds law. As is known, this law is heuristic and, to date, there is no rigorous justification. The article of A. Biryuk deals with the Cauchy problem for a multi-dimensional Burgers equation with periodic boundary conditions. Estimates in suitable norms for the corresponding solutions are derived for "large" Reynolds numbers, and their relation with the Kolmogorov-Obukhov law are discussed. Similar estimates are also obtained for the Navier-Stokes equation. In the late sixties J. L. Lions introduced a "perturbation" of the Navier Stokes equations in which he added in the linear momentum equation the hyper dissipative term (-Ll),Bu, f3 ~ 5/4, where Ll is the Laplace operator. This term is referred to as an "artificial" viscosity. Even though it is not physically moti vated, artificial viscosity has proved a useful device in numerical simulations of the Navier-Stokes equations at high Reynolds numbers. The paper of of D. Chae and J. Lee investigates the global well-posedness of a modification of the Navier Stokes equation similar to that introduced by Lions, but where now the original dissipative term -Llu is replaced by (-Ll)O:u, 0 S Ct

Book Synopsis Topics in Computational Wave Propagation by : Mark Ainsworth
Download or read book Topics in Computational Wave Propagation written by Mark Ainsworth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: These ten detailed and authoritative survey articles on numerical methods for direct and inverse wave propagation problems are written by leading experts. Researchers and practitioners in computational wave propagation, from postgraduate level onwards, will find the breadth and depth of coverage of recent developments a valuable resource. The articles describe a wide range of topics on the application and analysis of methods for time and frequency domain PDE and boundary integral formulations of wave propagation problems. Electromagnetic, seismic and acoustic equations are considered. Recent developments in methods and analysis ranging from finite differences to hp-adaptive finite elements, including high-accuracy and fast methods are described with extensive references.
Book Synopsis Navier—Stokes Equations by : Roger Temam
Download or read book Navier—Stokes Equations written by Roger Temam and published by Elsevier. This book was released on 2016-06-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Navier-Stokes Equations: Theory and Numerical Analysis focuses on the processes, methodologies, principles, and approaches involved in Navier-Stokes equations, computational fluid dynamics (CFD), and mathematical analysis to which CFD is grounded. The publication first takes a look at steady-state Stokes equations and steady-state Navier-Stokes equations. Topics include bifurcation theory and non-uniqueness results, discrete inequalities and compactness theorems, existence and uniqueness theorems, discretization of Stokes equations, existence and uniqueness for the Stokes equations, and function spaces. The text then examines the evolution of Navier-Stokes equations, including linear case, compactness theorems, alternate proof of existence by semi-discretization, and discretization of the Navier-Stokes equations. The book ponders on the approximation of the Navier-Stokes equations by the projection and compressibility methods; properties of the curl operator and application to the steady-state Navier-Stokes equations; and implementation of non-conforming linear finite elements. The publication is a valuable reference for researchers interested in the theory and numerical analysis of Navier-Stokes equations.
