Book excerpt: DANS UN DIAGRAMME D'ETAT DE TYPE ZENZ, LE REGIME D'ECOULEMENT DISCONTINU GAZ-SOLIDE SE CARACTERISE PAR DE GRANDES FLUCTUATIONS DE PRESSION ET DE FAIBLES VITESSES SUPERFICIELLES DE LA PHASE PORTEUSE. IL SE SITUE ENTRE LES REGIMES DE SALTATION, LES LITS DE PARTICULES MOBILES ET REPRESENTE PAR CONSEQUENT UNE FAMILLE D'ECOULEMENTS DE TYPE TRANSITOIRE. DE NOMBREUX TRAVAUX ONT ETE CONSACRES A LA CARACTERISATION FONDAMENTALE DE CE REGIME EN CONDUITE HORIZONTALE ET VERTICALE, MAIS LE CAS DES SINGULARITES RESTE A CE JOUR PEU ETUDIE. AINSI, L'OBJECTIF DES TRAVAUX PRESENTES DANS CE MEMOIRE EST LA MISE EN EVIDENCE DU ROLE DES CHANGEMENTS DE DIRECTION SUR L'ORGANISATION DE L'ECOULEMENT DANS LES CIRCUITS ET LA MISE EN UVRE DES HYPOTHESES NECESSAIRES A LA MODELISATION DES EFFORTS APPLIQUES AUX COUDES, AU PASSAGE DE L'ECOULEMENT. POUR CE FAIRE UNE PREMIERE PARTIE EST CONSACREE A LA REVUE GENERALE BIBLIOGRAPHIQUE DANS LAQUELLE ON S'ATTACHE A METTRE EN EVIDENCE LES PROPRIETES PRINCIPALES CARACTERISANT L'ECOULEMENT DISCONTINU GAZ-SOLIDE EN CONDUITE DROITE AINSI QUE L'INFLUENCE DE LA PRESENCE DE CHANGEMENTS DE DIRECTION SUR LES ECOULEMENTS DIPHASIQUES. UNE SECONDE PARTIE APPARAIT A LA FOIS COMME UNE ANALYSE QUALITATIVE ET QUANTITATIVE DU COMPORTEMENT DE L'ECOULEMENT AU VOISINAGE D'UN CHANGEMENT DE DIRECTION A RAYON DE COURBURE NUL, PLACE DANS UNE CONFIGURATION GEOMETRIQUE HORIZONTALE-VERTICALE ET EN UTILISANT DES TECHNIQUES DE VISUALISATION. CETTE PARTIE DE L'ETUDE PERMET DE FORMULER CERTAINES DES HYPOTHESES NECESSAIRES A LA MODELISATION DES EFFORTS PROVOQUES PAR LE PASSAGE DE L'ECOULEMENT DANS LA SINGULARITE. TOUTEFOIS, DEVANT LES LIMITES DES TECHNIQUES DE VISUALISATION, UNE DERNIERE PARTIE EST CONSACREE AU DEVELOPPEMENT ET A LA VALIDATION D'UNE INSTRUMENTATION SPECIFIQUE FORMANT UN SYSTEME DE DETECTION ET DE RECONNAISSANCE DES FORMES PRINCIPALES DE L'ECOULEMENT DISCONTINU GAZ-SOLIDE. CETTE METHODE APPLIQUEE EN CONDUITE DROITE HORIZONTALE AU VOISINAGE DE CHANGEMENTS DE DIRECTION A RAYON DE COURBURE CONSTANT, PERMET DE METTRE EN EVIDENCE LES PRINCIPALES PROPRIETES DE L'ECOULEMENT QUI SONT CONFRONTEES AUX RESULTATS BIBLIOGRAPHIQUES CONNUS ET AUX RESULTATS OBTENUS GRACE A L'INSTRUMENTATION D'UN SITE REEL DE GRANDE LONGUEUR FONCTIONNANT EN REGIME DISCONTINU ET POUR LEQUEL LES EFFETS DE SINGULARITES PEUVENT ETRE NEGLIGES. ENFIN, UNE SYNTHESE EST PROPOSEE POUR METTRE EN EVIDENCE LES MODELES ADAPTABLES AUX PROBLEMES POSES PAR LE PASSAGE DE L'ECOULEMENT DANS LES CHANGEMENTS DE DIRECTION ET LA CONTRIBUTION APPORTEE PAR LE SYSTEME DE DETECTION EST ANALYSEE.

Book excerpt: Genmix: A General Computer Program for Two-dimensional Parabolic Phenomena explains a computer program called GENMIX. The main intention of the program is to be used as a tool of instructions. The name of the program is a mixture of two considerations: its generality and its concern for mixing processes. The book aims to help the potential user to understand the physical and mathematical basis of the topic computer program. It is also the aim of the book to make the program applicable to practical problems. The book is arranged in such a way as to parallel a course of lectures and associated computer-workshop sessions wherein the student is allowed to do some elementary computations as soon as he has gained some knowledge of the method. The book contains the mathematical, physical, and computer-coding aspects of the program. Concepts such as the boundary layer, two-dimensional, and steady- flow are defined and discussed in depth. The text will be a useful tool for computer instructors and students.

Available in PDF, EPUB and Kindle. Book excerpt: Calculations in Furnace Technology presents the theoretical and practical aspects of furnace technology. This book provides information pertinent to the development, application, and efficiency of furnace technology. Organized into eight chapters, this book begins with an overview of the exothermic reactions that occur when carbon, hydrogen, and sulfur are burned to release the energy available in the fuel. This text then evaluates the efficiencies to measure the quantity of fuel used, of flue gases leaving the plant, of air entering, and the heat lost to the surroundings. Other chapters consider that it is important to determine the amount of carbon discharged with the ashes, the quantity and composition of any tar produced, so that a carbon balance can be applied. The final chapter describes the various reactions within the furnace atmosphere and between charges and atmosphere. This book is a valuable resource for fuel technologists, heating and ventilating engineers, and plant operators.

Book excerpt: This volume documents the proceedings of the Symposium on Emissions from Continuous Combustion Systems that was held at the General Motors Research Laboratories, Warren, Michigan on September 27 and 28, 1971. This symposium was the fifteenth in an annual series presented by the Research Laboratories. Each symposium has covered a different technical discipline. To be selected as the theme of a symposium, the subject must be timely and of vital interest to General Motors as well as to the technical community at large. For each symposium, the practice is to solicit papers at the forefront of research from recognized authorities in the technical discipline of interest. Approximately sixty scientists and engineers from academic, government and industrial circles in this country and abroad are then invited to join about an equal number of General Motors technical personnel to discuss freely the commissioned papers. The technical portion of the meeting is supplemented by social functions at which ample time is afforded for informal exchanges of ideas amongst the participants. By such a direct interaction of a small and select group of informed participants, it is hoped to extend the boundaries of research in the selected technical field.
