Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL APPORTE UNE CONTRIBUTION A LA MODELISATION D'UNE FUITE DE VAPEUR D'EAU A HAUTE PRESSION DANS DU SODIUM LIQUIDE. CE PHENOMENE DESTRUCTIF, TRES REACTIF, APPELE WASTAGE, PEUT SURVENIR DANS UN GENERATEUR DE VAPEUR DE CENTRALE NUCLEAIRE A NEUTRONS RAPIDES. UNE SIMULATION EN MAQUETTE FROIDE DE CE PROCESSUS PERMET D'ETUDIER LA STRUCTURE D'UN JET DIPHASIQUE IMMERGE. UNE ETUDE BIBLIOGRAPHIQUE PRECISE LA GEOMETRIE ET LA STRUCTURE INTERNE DE L'ECOULEMENT CONSIDERE, AINSI QUE LES MOYENS EXPERIMENTAUX PERMETTANT DE LES CARACTERISER. LES NOMBREUX RESULTATS EXPERIMENTAUX PRESENTES CONCERNENT DES JETS TURBULENTS D'AZOTE DANS DE L'EAU. DIFFERENTES LOIS PARAMETRIQUES SONT ETABLIES QUI MONTRENT L'EVOLUTION DU TAUX DE PRESENCE DU GAZ (MESURE AU MOYEN D'UNE FIBRE OPTIQUE ALIMENTEE PAR UN LASER) EN FONCTION DE GRANDEURS AXIALES ET RADIALES. CONSIDERANT L'ENTRAINEMENT DU LIQUIDE (MESURE PAR UNE SONDE ISOCINETIQUE), UN MODELE BASE SUR UN ECOULEMENT BIDIMENSIONNEL AVEC GLISSEMENT EST PROPOSE. ENFIN, UNE ETUDE EXPERIMENTALE EST CONDUITE AFIN DE MIEUX CERNER LE CARACTERE FLUCTUANT DE L'ECOULEMENT

Available in PDF, EPUB and Kindle. Book excerpt: Honoring the contributions of one of the field's leading experts, Lu Ting, this indispensable volume contains important new results at the cutting edge of research. A wide variety of significant new analytical and numerical results in critical areas are presented, including point vortex dynamics, superconductor vortices, cavity flows, vortex breakdown, shock/vortex interaction, wake flows, magneto-hydrodynamics, rotary wake flows, and hypersonic vortex phenomena.The book will be invaluable for those interested in the state of the art of vortex dominated flows, both from a theoretical and applied perspective.Professor Lu Ting and Joe Keller have worked together for over 40 years. In their first joint work entitled ?Periodic vibrations of systems governed by nonlinear partial differential equations?, perturbation analysis and bifurcation theory were used to determine the frequencies and modes of vibration of various physical systems. The novelty was the application to partial differential equations of methods which, previously, had been used almost exclusively on ordinary differential equations. Professsor Lu Ting is an expert in both fluid dynamics and the use of matched asymptotic expansions. His physical insight into fluid flows has led the way to finding the appropriate mathematical simplications used in the solutions to many difficult flow problems.

Book excerpt: From Multicores and GPUs to Petascale. Parallel computing technologies have brought dramatic changes to mainstream computing the majority of todays PCs, laptops and even notebooks incorporate multiprocessor chips with up to four processors. Standard components are increasingly combined with GPUs Graphics Processing Unit, originally designed for high-speed graphics processing, and FPGAs Free Programmable Gate Array to build parallel computers with a wide spectrum of high-speed processing functions. The scale of this powerful hardware is limited only by factors such as energy consumption and thermal control. However, in addition to"

Book excerpt: Modelling Fluid Flow presents invited lectures, workshop summaries and a selection of papers from a recent international conference CMFF '03 on fluid technology. The lectures follow the current evolution and the newest challenges of the computational methods and measuring techniques related to fluid flow. The workshop summaries reflect the recent trends, open questions and unsolved problems in the mutually inspiring fields of experimental and computational fluid mechanics. The papers cover a wide range of fluids engineering, including reactive flow, chemical and process engineering, environmental fluid dynamics, turbulence modelling, numerical methods, and fluid machinery.
