Book Description
ON S'INTERESSE DANS CETTE THESE A L'ETUDE DES SYSTEMES HYPERBOLIQUES DE LOIS DE CONSERVATION NON-LINEAIRES AVEC TERMES SOURCES. D'UN POINT DE VUE THEORIQUE, ON COMMENCE PAR ETUDIER LE PROBLEME DE RIEMANN GENERALISE. ENSUITE, ON MONTRE QU'UNE CONDITION SUFFISANTE DE CONVERGENCE DES APPROXIMATIONS VISQUEUSES POUR UNE LOI SCALAIRE NON-HOMOGENE EST D'ASSURER UNE ESTIMATION UNIFORME EN AMPLITUDE. LE PROBLEME EST PLUS DELICAT POUR UN SYSTEME. L'ETUDE DES DISCRETISATIONS IMPLICITES D'UNE LOI SCALAIRE GENERALE MONTRE QU'IL EXISTE DES CONDITIONS DE TYPE CFL POUR GARANTIR L'INVERSIBILITE DU SCHEMA ET PREVENIR L'APPARITIONS D'OSCILLATIONS PARASITES DANS LA SOLUTION NUMERIQUE. ON INTRODUIT ENSUITE UN SCHEMA “WELL-BALANCED” AU SENS DE GREENBERG ET LEROUX CONVERGENT VERS LA SOLUTION ENTROPIQUE DANS LE CAS SCALAIRE. L'EXTENSION AUX SYSTEMES GENERAUX SE FAIT PAR LE BIAIS D'UNE REFORMULATION DES TERMES SOURCES EN PRODUITS NON-CONSERVATIFS. ON CALCULE ALORS UNE LINEARISEE DE TYPE ROE POUR LES EQUATIONS D'EULER NON-HOMOGENES. PAR SOUCI DE ROBUSTESSE, ON DERIVE AUSSI UN SCHEMA DE TYPE “DECOMPOSITION DE FLUX” NON-CONSERVATIF PERMETTANT D'APPROCHER DES SYSTEMES VARIES ET CONSISTANT AVEC LES LIMITES RELAXEES. DES TESTS SONT AUSSI EFFECTUES EN REGIME RESONANT ET POUR DES PROBLEMES DIPHASIQUES SIMPLIFIES BIDIMENSIONNELS.

Book Description
This work traces the development of numerical methods for non-Newtonian flows from the late 1960s to 2001. It begins with broad coverage of non-Newtonian fluids, including their mathematical modelling and analysis, and then specific computational techniques are discussed.

Book Description
Numerical Computation of Internal and External Flows Volume 2: Computational Methods for Inviscid and Viscous Flows C. Hirsch, Vrije Universiteit Brussel, Brussels, Belgium This second volume deals with the applications of computational methods to the problems of fluid dynamics. It complements the first volume to provide an excellent reference source in this vital and fast growing area. The author includes material on the numerical computation of potential flows and on the most up-to-date methods for Euler and Navier-Stokes equations. The coverage is comprehensive and includes detailed discussion of numerical techniques and algorithms, including implementation topics such as boundary conditions. Problems are given at the end of each chapter and there are comprehensive reference lists. Of increasing interest, the subject has powerful implications in such crucial fields as aeronautics and industrial fluid dynamics. Striking a balance between theory and application, the combined volumes will be useful for an increasing number of courses, as well as to practitioners and researchers in computational fluid dynamics.

Book Description
Haim Brezis has made significant contributions in the fields of partial differential equations and functional analysis, and this volume collects contributions by his former students and collaborators in honor of his 60th anniversary at a conference in Gaeta. It presents new developments in the theory of partial differential equations with emphasis on elliptic and parabolic problems.

Book Description
This book contains a valuable discussion of renormalization through the addition of counterterms to the Lagrangian, giving the first complete proof of the cancellation of all divergences in an arbitrary interaction. The author also introduces a new method of renormalizing an arbitrary Feynman amplitude, a method that is simpler than previous approaches and can be used to study the renormalized perturbation series in quantum field theory.
