Available in PDF, EPUB and Kindle. Book excerpt: Microscopic re-examination of geomaterials consisting of aggregates can shed light on macroscopic behaviour, including compressibility, anisotropy, yielding, creep, cyclic liquefaction and shear rupture. As a result of this process of examination, new methods of material characterization emerge, leading to a greater degree of accuracy in the specification of new constitutive models with physically-meaningful parameters. The impetus behind this development is an increasing awareness on sustainability, leading to the more efficient use of recycled materials for geotechnical applications. The characteristics of recycled materials, such as compressibility and self-hardening, may differ significantly from those of natural materials, and it is crucial that evaluation is made from a specifically particulate perspective.

Download or read book Low Reynolds number hydrodynamics written by J. Happel and published by Springer. This book was released on 2012-02-09 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: One studying the motion of fluids relative to particulate systems is soon impressed by the dichotomy which exists between books covering theoretical and practical aspects. Classical hydrodynamics is largely concerned with perfect fluids which unfortunately exert no forces on the particles past which they move. Practical approaches to subjects like fluidization, sedimentation, and flow through porous media abound in much useful but uncorrelated empirical information. The present book represents an attempt to bridge this gap by providing at least the beginnings of a rational approach to fluid particle dynamics, based on first principles. From the pedagogic viewpoint it seems worthwhile to show that the Navier-Stokes equations, which form the basis of all systematic texts, can be employed for useful practical applications beyond the elementary problems of laminar flow in pipes and Stokes law for the motion of a single particle. Although a suspension may often be viewed as a continuum for practical purposes, it really consists of a discrete collection of particles immersed in an essentially continuous fluid. Consideration of the actual detailed boundary value problems posed by this viewpoint may serve to call attention to the limitation of idealizations which apply to the overall transport properties of a mixture of fluid and solid particles.

Available in PDF, EPUB and Kindle. Book excerpt: This is the final technical report on a three-year program of research on the microstructural and continuum mechanics of granular media and geomaterials initiated under the AFOSR Particulate Mechanics Program. The research has led to the development of new theoretical models of microstructure, numerical simulation of granular assemblages, and development of new experimental techniques. The overall goal of the work is to provide a sound microstructural basis for understanding continuum behavior and elucidating structurally and geologically important processes such as the propagation of acoustic an seismic waves, the quasi-static yield of granular media, the structural stability of soils and the noninvasive testing of geomaterials. The research effort has been mainly devoted to the mechanics of dense suspensions and granular media in the quasi-static flow regime, with emphasis on shearing and dilatational instabilities. A summary is given immediately below of accomplishments and plans for continuing efforts.

This book was released on 2015-09-03 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the Discrete Element Method (DEM) technique, a discontinuum modelling approach that takes into account the fact that granular materials are composed of discrete particles which interact with each other at the microscale level. This numerical simulation technique can be used both for dispersed systems in which the particle-particle interactions are collisional and compact systems of particles with multiple enduring contacts. The book provides an extensive and detailed explanation of the theoretical background of DEM. Contact mechanics theories for elastic, elastic-plastic, adhesive elastic and adhesive elastic-plastic particle-particle interactions are presented. Other contact force models are also discussed, including corrections to some of these models as described in the literature, and important areas of further research are identified. A key issue in DEM simulations is whether or not a code can reliably simulate the simplest of systems, namely the single particle oblique impact with a wall. This is discussed using the output obtained from the contact force models described earlier, which are compared for elastic and inelastic collisions. In addition, further insight is provided for the impact of adhesive particles. The author then moves on to provide the results of selected DEM applications to agglomerate impacts, fluidised beds and quasi-static deformation, demonstrating that the DEM technique can be used (i) to mimic experiments, (ii) explore parameter sweeps, including limiting values, or (iii) identify new, previously unknown, phenomena at the microscale. In the DEM applications the emphasis is on discovering new information that enhances our rational understanding of particle systems, which may be more significant than developing a new continuum model that encompasses all microstructural aspects, which would most likely prove too complicated for practical implementation. The book will be of interest to academic and industrial researchers working in particle technology/process engineering and geomechanics, both experimentalists and theoreticians.

Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the mechanism of stress and deformation in particulate materials under repeated application of moving surface loads. It consisted of two complimentary phases: the theoretical development of model to characterize the propagation of stress and deformation in the medium anf the experimental investigation of its adequacy. The research project built on the earlier work of bourdeau, who brought together the probabilistic concept of stress transmission in granular bodies (Harr) and the analogous stochastically based deformation mechanism proposed by Litwiniszyn, to investigate the response of particulate material to vertically applied slowly moving surface loadings. The perceived advantage of this methodology is that the response of granular materials may be characterized by a very few parameters, whereas the older stress-dilatancy and yield theories abound in extra parameters. A fine dry silt soil was tested under both repeated static loading and quasi-mobile loading. An array of lead shot was placed periodically throughout the soil body, and records were made of the deformation of the soil under the surface applied loading through exposure of the soil model to X-rays, The conclusion was drawn that response of dry granular material to vertically applied moving loads is one-dimensional, and the magnitude of deformation may be estimated from an equivalent static loading.

Download or read book Processing of Particulate Solids written by J.P. Seville and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over half of the products of the chemical and process industries are sold in a particulate form. The range of such products is vast: from agrochemicals to pigments, from detergents to foods, from plastics to pharmaceuticals. However, surveys of the performance of processes designed to produce particulate products have consistently shown inadequate design and poor reliability. `Particle technology' is a new subject facing new challenges. Chemical and process engineering is becoming less concerned with the design of plants to produce generic simple chemicals (which are often single phase fluids) and is now more concerned with speciality `effect' chemicals which may often be in particulate form. Chemical and process engineers are also being recruited in increasing numbers into areas outside their tranditional fields, such as the food industry, pharmaceuticals and the manufacture of a wide variety of consumer products. This book has been written to meet their needs. It provides comprehensive coverage of the technology of particulate solids, in a form which is both accessible and concise enough to be useful to engineering and science students in the final year of an undergraduate degree, and at Master's level. Although it was written with students of chemical engineering in mind, it will also be of use and interest to students of other disciplines. It comprises an account of the fundamentals of teh subject, illustrated by worked examples, and followed by a wide range of selected applications.
