Book Synopsis Propriété physiques du béton et de ses constituants by : OLLIVIER Jean-Pierre
Download or read book Propriété physiques du béton et de ses constituants written by OLLIVIER Jean-Pierre and published by Lavoisier. This book was released on 2012-06-01 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: À l'état durci, le béton est un matériau poreux complexe. Ses propriétés d'usage (performances mécaniques ou thermiques, durabilité…) sont liées à sa structure poreuse qui elle-même dépend de l'arrangement des grains à l'état frais. Étudiant les propriétés des matériaux granulaires et celles de leurs mélanges, cet ouvrage propose différents outils permettant au formulateur de concevoir des bétons de façon innovante. Afin de décrire les méthodes de caractérisation des matériaux, il analyse les propriétés physiques sur lesquelles elles reposent et établit ainsi leurs limites. Il développe également les notions de porosité et de surface spécifique et présente les propriétés de transport des bétons (diffusion et perméation). Chaque chapitre se termine par plusieurs exercices permettant d'assimiler les connaissances théoriques présentées et de les appliquer à des problèmes concrets de génie civil.

Book Synopsis Flows and Chemical Reactions in Heterogeneous Mixtures by : Roger Prud'homme
Download or read book Flows and Chemical Reactions in Heterogeneous Mixtures written by Roger Prud'homme and published by John Wiley & Sons. This book was released on 2014-10-30 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book - a sequel of previous publications 'Flows and Chemical Reactions' and 'Chemical Reactions in Flows and Homogeneous Mixtures' - is devoted to flows with chemical reactions in heterogeneous environments. Heterogeneous media in this volume include interfaces and lines. They may be the site of radiation. Each type of flow is the subject of a chapter in this volume. We consider first, in Chapter 1, the question of the generation of environments biphasic individuals: dusty gas, mist, bubble flow. Chapter 2 is devoted to the study at the mesoscopic scale: particle-fluid exchange of momentum and heat with determination of the respective exchange coefficients. In Chapter 3, we establish simplified equations of macroscopic balance for mass, for the momentum and energy, in the case of particles of one size (monodisperse suspension). Radiative phenomena are presented in Chapter 5.
Book Synopsis Fundamentals of the Physical-Chemistry of Pulverized Coal Combustion by : L Lahaye
Download or read book Fundamentals of the Physical-Chemistry of Pulverized Coal Combustion written by L Lahaye and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of coal for the production of energy is certainly not a new area of research. Many research works were carried out to improve the efficiency of industrial and domestic facilities. In the sixties, however, because of the availability and low cost of petroleum, coal consumption decreased and the research effort in this area was minimum. Meanwhile, the situation has totally changed. Considering the reserves of oil and the instability ofregions where they are located, it is becoming absolutely necessary to develop other sources of energy.The major alternative to oil appears to be coal, at least for the near future. Indeed, the reserves known today represent several centuries of energy consumption.!t is therefore becoming urgent to develop efficient and non polluting technologies to produce energy from coal. The main possibilities are : · liquefaction · gasification · directed combustion. Research and development efforts on liquefaction have been considerably reduced because of high cost of technologies involved and poor prospects for the next two decades. Research works on gasification are progressing; it is a promising approach. However, direct combustion either in pulverized coal furnaces or in fluidized beds is the more promising way of expanding rapidly the utilization of coal. These techniques are already used in some facilities but many environmental problems remain, slowing down their development.

Download or read book Mechanical Behavior of Anisotropic Solids / Comportment Méchanique des Solides Anisotropes written by J.P. Boehler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 926 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1978, the European Mechanics Committee and the French Centre National de la Recherche Scientifique agreed to the organization of an Interna tional Colloquium on the "Mechanical Behavior of Anisotropic Solids". The meeting was held at Villard-de-Lans (near Grenoble, France) from 19th to 22 nd June 1979. The Colloquium considered mechanical aspects of the anisotropy of solids, both initial and induced by permanent deformation, anisotropic hardening and damage, oriented fissuration, etc. Topics concerned mathematical, experimental and engineering aspects of the anisotropy of metals, composites, soils and rocks. The aim of the Colloquium was to bring together experimentalists, theoretecians and engineers interested in various features of mechanical anisotropy, in order to permit an interdisciplinary exchange of understanding, experience and methods. A detailed description of the scope, aim and proposed topics is contained in the Preface. The announcement of the Colloquium attracted a large number of sub mitted contributions. Conforming with the principles of Euromech Colloquia and of the Colloques Internationaux du CNRS, the accepted contributions were limited to 50 communications. A general description of the scientific program is to be found in the Preface. Five general lectures gave state-of-the-art reports concerning some areas of the behavior of anisotropic solids; the 50 communications were divided into 12 sessions dealing with specific topics (see "Contents"). In order to facilitate subsequent contact between the reader and the contributors, full addresses are given in the "List of Authors."

Download or read book Catalyst Characterization written by Boris Imelik and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: to the Fundamental and Applied Catalysis Series Catalysis is important academically and industrially. It plays an essential role in the manufacture of a wide range of products, from gasoline and plastics to fertilizers and herbicides, which would otherwise be unobtainable or prohibitive ly expensive. There are few chemical-or oil-based material items in modern society that do not depend in some way on a catalytic stage in their manufacture. Apart from manufacturing processes, catalysis is finding other important and over-increasing uses; for example, successful applications of catalysis in the control ofpollution and its use in environmental control are certain to in crease in the future. The commercial import an ce of catalysis and the diverse intellectual challenges of catalytic phenomena have stimulated study by a broad spectrum of scientists including chemists, physicists, chemical engineers, and material scientists. Increasing research activity over the years has brought deeper levels of understanding, and these have been associated with a continually growing amount of published material. As recentlyas sixty years ago, Rideal and Taylor could still treat the subject comprehensively in a single volume, but by the 19 50s Emmett required six volumes, and no conventional multivolume text could now cover the whole of catalysis in any depth.
