Book Description
Computational Fluid Dynamics: An Introduction grew out of a von Karman Institute (VKI) Lecture Series by the same title ?rst presented in 1985 and repeated with modi?cations every year since that time. The objective, then and now, was to present the subject of computational ?uid dynamics (CFD) to an audience unfamiliar with all but the most basic numerical techniques and to do so in such a way that the practical application of CFD would become clear to everyone. A second edition appeared in 1995 with updates to all the chapters and when that printing came to an end, the publisher requested that the editor and authors consider the preparation of a third edition. Happily, the authors received the request with enthusiasm. The third edition has the goal of presenting additional updates and clari?cations while preserving the introductory nature of the material. The book is divided into three parts. John Anderson lays out the subject in Part I by ?rst describing the governing equations of ?uid dynamics, concentrating on their mathematical properties which contain the keys to the choice of the numerical approach. Methods of discretizing the equations are discussed and transformation techniques and grids are presented. Two examples of numerical methods close out this part of the book: source and vortex panel methods and the explicit method. Part II is devoted to four self-contained chapters on more advanced material. Roger Grundmann treats the boundary layer equations and methods of solution.

Book Description
Les écoulements avec réactions chimiques peuvent intervenir dans des domaines variés tels que la combustion, le génie des procédés, l’aéronautique, l’environnement atmosphérique et aquatique. Les exemples d’application choisis dans ce volume portent principalement sur les mélanges réactifs homogènes susceptibles d’intervenir dans les propulseurs, en génie des procédés et en combustion : - propagation du son et écoulements monodimensionnels non diffusifs dans les tuyères pouvant comporter des déséquilibres des modes internes d’énergie des molécules ; - réacteurs chimiques idéaux, stabilisation de leurs points de fonctionnement stationnaires dans le cas homogène à mélange parfait et instruments classiques d’analyse expérimentale et théorique tels les bilans de population, la distribution des temps de séjour et celle des âges ; - flammes laminaires et turbulentes en séparant bien celles qui sont prémélangées de celles qui ne le sont pas et qui ne relèvent pas des mêmes mécanismes, mais qui interviennent conjointement dans le cas des flammes triples. Écoulements et réactions chimiques 2 apporte également des précisions sur l’analyse dimensionnelle, la thermodynamique statistique avec couplage entre modes internes d’énergie et réactions chimiques, l’apparition et la dissipation de la turbulence fluide ainsi que son traitement statistique, les bifurcations, les flammes en milieu confiné et de diffusion.

Book Description
DANS LE CADRE DE CE TRAVAIL, DES TECHNIQUES ADAPTEES AUX MAILLAGES NON STRUCTURES ONT ETE DEVELOPPEES. LES EQUATIONS DE NAVIER-STOKES COMPRESSIBLES ONT ETE DISCRETISEES ET INTEGREES EN UTILISANT UN SCHEMA DE TAYLOR-GALERKIN A DEUX PAS. CE TRAVAIL EST SUBDIVISE EN TROIS PARTIES: 1) LA PREMIERE PARTIE, A ETE CONSACREE A LA STRUCTURE DES DONNEES PERMETTANT AINSI UNE UTILISATION OPTIMALE DES FACILITES VECTORIELLES ET PARALLELES QUE PRESENTENT AUJOURD'HUI LES SUPER-CALCULATEURS A MEMOIRES SEPAREES. DANS LA SECONDE PARTIE, DEUX METHODES DE SOLUTION POUR UN SYSTEME D'EQUATIONS AVEC DES MATRICES NON-STRUCTUREES ONT ETE IMPLANTEES ET COMPAREES. UNE METHODE ITERATIVE UTILISANT LA DIAGONALE DOMINANTE DE MATRICE MASSE. L'AUTRE TECHNIQUE D'INVERSION DE MATRICE EST BASEE SUR LA DECOMPOSITION LU DE LA MATRICE ET UTILISE UNE APPROCHE MULTI-FRONTALE. LA STRUCTURE ARBORISSANTE DE DECOMPOSITION DEFINIT LE DEGRE POSSIBLE DU PARALLELISME A CHAQUE NIVEAU PAR LE NOMBRE D'ELEMENTS. LA DERNIERE PARTIE, CONSTITUANT LA PARTIE PRINCIPALE DE CE TRAVAIL, A ETE CONSACREE AUX MAILLAGES. UNE METHODE D'AVANCE FRONTALE POUR LA GENERATION ET L'ADAPTATION DE MAILLAGE A ETE DEVELOPPEE. CETTE TECHNIQUE REDUIT ENORMEMENT L'INTERACTION HOMME/MACHINE ET LE TRAVAIL N'EST PAS MODIFIE AVEC UN DOMAINE DE CALCUL PLUS COMPLEXE. DE PLUS LE NOMBRE DE POINTS NECESSAIRES A CAUSE DES ETIREMENTS DES ELEMENTS GENERES A ETE OPTIMISE. DES RESULTATS NUMERIQUES POUR DES ECOULEMENTS VISQUEUX ET NON VISQUEUX, EN CONFIGURATION BIDIMENSIONNELLE AUTOUR D'UNE DOUBLE ELLIPSE ET D'UN CYLINDRE ONT ETE OBTENUS, POUR LES ECOULEMENTS SUBSONIQUES A HYPERSONIQUES ET COMPARABLES AUX RESULTATS EXISTANTS.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
This well-written book explains the theory of spectral methods and their application to the computation of viscous incompressible fluid flow, in clear and elementary terms. With many examples throughout, the work will be useful to those teaching at the graduate level, as well as to researchers working in the area.
