Available in PDF, EPUB and Kindle. Book excerpt: LE BUT DE CETTE THESE EST L'ETUDE DE DEUX PROBLEMES D'ECOULEMENT DANS LES MILIEUX POREUX. POUR DECRIRE CES ECOULEMENTS ON UTILISE LA CONVERGENCE DOUBLE-ECHELLE ET LA CONVERGENCE TRIPLE-ECHELLE. PLUS PRECISEMENT LES DEUX PROBLEMES ETUDIES SONT: L'ECOULEMENT D'UN FLUIDE VISQUEUX A TRAVERS UN MILIEU POREUX ELASTIQUE DE FAIBLE EPAISSEUR ET L'ECOULEMENT D'UN FLUIDE DANS UN MILIEU POREUX FISSURE. DANS LE PREMIER CHAPITRE ON CONSIDERE LE CAS DU SYSTEME STOKES DANS LE FLUIDE, LE SOLIDE EST ELASTIQUE ET CONSIDERE DANS LE CADRE DE L'ELASTICITE LINEARISEE. LA STRUCTURE PERIODIQUE DU DOMAINE ET LA FAIBLE EPAISSEUR DU SOLIDE IMPOSE L'INTRODUCTION DE DEUX PETITS PARAMETRES. ON CONSTRUIT UN NOUVEAU PROLONGEMENT DE LA PRESSION DANS LA PARTIE SOLIDE, DIFFERENT DE CEUX CONNUS JUSQU'A MAINTENANT, QUI NOUS ASSURE LA CONTINUITE DU TENSEUR DES CONTRAINTES SUR L'INTERFACE FLUIDE-SOLIDE. L'EQUATION LIMITE FINALE DECRIT UN MILIEU VISCOELASTIQUE AVEC UN TERME DE MEMOIRE EVANESCENTE. LA METHODE UTILISEE EST CELLE DE LA CONVERGENCE DOUBLE-ECHELLE. DANS LE CHAPITRE 2 ON CONSIDERE LE SYSTEME NAVIER-STOKES LINEARISE DANS LE FLUIDE. LES TECHNIQUES SONT LES MEMES QUE POUR LE CAS STOKES ; L'EQUATION MACROSCOPIQUE CONTIENT UN TERME DE MEMOIRE EVANESCENTE, MAIS AUSSI UN TERME NOUVEAU. DANS LE TROISIEME CHAPITRE ON ETUDIE L'ECOULEMENT D'UN FLUIDE DANS UN MILIEU POREUX FISSURE. D'UN POINT DE VUE MECANIQUE C'EST UN PROBLEME DE DOUBLE POROSITE, DANS LE CADRE D'UN MILIEU AVEC DOUBLE PERIODICITE. LE RESULTAT D'HOMOGENEISATION OBTENU MONTRE QU'ON A UNE LOI DE DARCY AU NIVEAU MACROSCOPIQUE, ET QU'AU MOINS DANS LE CAS STATIONNAIRE LE MODELE AVEC DOUBLE PERIODICITE ET LE MODELE AVEC DOUBLE POROSITE COINCIDENT. LA METHODE UTILISEE EST CELLE DE LA CONVERGENCE TRIPLE-ECHELLE

This book was released on 1992 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA THESE EST CONSTITUEE DE TROIS PARTIES. DANS LA PREMIERE PARTIE ON ETUDIE PAR LA METHODE DE L'HOMOGENEISATION LA CORRECTION APPORTEE, A LA LOI DE DARCY LINEAIRE, PAR LA PRISE EN COMPTE AU NIVEAU LOCAL DES TERMES DE CONVECTION LORSQUE CEUX-CI RESTENT PETITS DEVANT LES TERMES DE VISCOSITE. DANS LES CAS D'ISOTROPIE MACROSCOPIQUE OU DE FILTRATION MONODIMENSIONNELLE, LE RESULTAT OBTENU INFIRME LA LOI DE FORCHEIMER GENERALEMENT EMPLOYEE DANS CES DEUX SITUATIONS. DANS LA SECONDE PARTIE, TOUJOURS AU MOYEN DE LA METHODE DE L'HOMOGENEISATION, ON MODELISE LA FILTRATION D'UN FLUIDE A TRAVERS UN MILIEU POREUX FISSURE DANS LE CAS DE FISSURES OCCUPANT UN VOLUME EQUIVALENT A CELUI DES PORES. LORSQUE LA POROSITE DES BLOCS POREUX N'EST NI GRANDE, NI PETITE LA CONNEXITE DES FISSURES JOUE UN ROLE PRIMORDIAL, CELA N'EST PLUS LE CAS LORSQUE CETTE POROSITE EST PROCHE DE 1. DANS LA TROISIEME PARTIE ON CONSIDERE UN BLOC CONSTITUE PAR LE MELANGE DE DEUX PHASES POREUSES DISTINCTES TELLES QUE L'UNE SOIT BEAUCOUP PLUS PERMEABLE QUE L'AUTRE, MAIS OCCUPE A L'OPPOSE UN VOLUME BEAUCOUP PLUS REDUIT. CETTE ETUDE PEUT ETRE CONSIDEREE COMME UNE PREMIERE APPROCHE POUR LA MODELISATION D'UN MILIEU POREUX FISSURE DONT LES FISSURES REPRESENTENT UNE INFIME PARTIE DU VOLUME

Download or read book Principles of Petroleum Reservoir Engineering written by Gian L. Chierici and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six years ago, at the end of my professional career in the oil industry, I left my management position within Agip S.p.A., a major multinational oil company whose headquarters are in Italy, to take up the chair in reservoir engineering at the University of Bologna, Italy. There, I decided to prepare what was initially intended to be a set of lecture notes for the students attending the course. However, while preparing these notes, I became so absorbed in the subject matter that I soon found myself creating a substantial volume of text which could not only serve as a university course material, but also as a reference for wider professional applications. Thanks to the interest shown by the then president of Agip, Ing. Giuseppe Muscarella, this did indeed culminate in the publication of the first Italian edition of this book in 1989. The translation into English and publication of these volumes owes much to the encouragement of the current president of Agip, Ing. Guglielmo Moscato. My grateful thanks are due to both gentlemen. And now - the English version, translated from the second Italian edition, and containing a number of revisions and much additional material. As well as providing a solid theoretical basis for the various topics, this work draws extensively on my 36 years of worldwide experience in the development and exploitation of oil and gas fields.
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Download or read book Space Structure and Randomness written by Michel Bilodeau and published by Springer Science & Business Media. This book was released on 2007-12-23 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space, structure, and randomness: these are the three key concepts underlying Georges Matheron’s scientific work. He first encountered them at the beginning of his career when working as a mining engineer, and then they resurfaced in fields ranging from meteorology to microscopy. What could these radically different types of applications possibly have in common? First, in each one only a single realisation of the phenomenon is available for study, but its features repeat themselves in space; second, the sampling pattern is rarely regular, and finally there are problems of change of scale. This volume is divided in three sections on random sets, geostatistics and mathematical morphology. They reflect his professional interests and his search for underlying unity. Some readers may be surprised to find theoretical chapters mixed with applied ones. We have done this deliberately. GM always considered that the distinction between the theory and practice was purely academic. When GM tackled practical problems, he used his skill as a physicist to extract the salient features and to select variables which could be measured meaningfully and whose values could be estimated from the available data. Then he used his outstanding ability as a mathematician to solve the problems neatly and efficiently. It was his capacity to combine a physicist’s intuition with a mathematician’s analytical skills that allowed him to produce new and innovative solutions to difficult problems. The book should appeal to graduate students and researchers working in mathematics, probability, statistics, physics, spatial data analysis, and image analysis. In addition it will be of interest to those who enjoy discovering links between scientific disciplines that seem unrelated at first glance. In writing the book the contributors have tried to put GM’s ideas into perspective. During his working life, GM was a genuinely creative scientist. He developed innovative concepts whose usefulness goes far beyond the confines of the discipline for which they were originally designed. This is why his work remains as pertinent today as it was when it was first written.

Download or read book The Self Potential Method written by André Revil and published by Cambridge University Press. This book was released on 2013-07-11 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: The self-potential method enables non-intrusive assessment and imaging of disturbances in electrical currents of conductive subsurface materials. It has an increasing number of applications, from mapping fluid flow in the subsurface of the Earth to detecting preferential flow paths in earth dams and embankments. This book provides the first full overview of the fundamental concepts of this method and its applications in the field. It discusses the historical perspective, laboratory investigations undertaken, the inverse problem and seismoelectric coupling, and concludes with the application of the self-potential method to geohazards, water resources and hydrothermal systems. Chapter exercises, online datasets and analytical software enable the reader to put the theory into practice. This book is a key reference for academic researchers and professionals working in the areas of geophysics, environmental science, hydrology and geotechnical engineering. It will also be valuable reading for related graduate courses.
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1985-03 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 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 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
