Download or read book Microparticle Dynamics in Electrostatic and Flow Fields written by Sheng Chen and published by Springer Nature. This book was released on 2023-04-30 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis proposes new approaches for modelling contacting interactions and electrostatic interactions between microparticles in the framework of the discrete element method and presents a systematic investigation on the agglomeration, migration and deposition of microparticles in presence of electrostatic and flow fields. It reports an exponential-form scaling for the size distribution of early-stage agglomerates in homogeneous isotropic turbulence and formulate the agglomeration and deagglomeration rates. The evolution of spherical clouds of charged particles that migrate under the action of an external electrostatic field is then investigated. Scaling laws of cloud radius and particle number density are obtained by solving a continuum convection equation. Finally, it investigates the deposition of charged particles on a flat plane and fibers. A dimensionless adhesion parameter is constructed to predict the structure of deposits. The temporal evolution of the deposit structure, particle capture efficiency, and the pressure drop are displayed with varying values of Coulomb repulsion and adhesion magnitudes.

Download or read book Particle particle Adhesion In Pharmaceutical Powder Handling written by Fridrun Podczeck and published by World Scientific. This book was released on 1998-07-31 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes the physical principles of adhesion between particles and surfaces. These principles are applied to pharmaceutical processes involved in the manufacture of solid dosage forms such as powders, granules, tablets and dry powder inhalations. To help in the understanding of these systems, physical properties of solid surfaces, and an introduction to the theory of friction is given. Techniques for measuring particle adhesion and fracture mechanical properties of powders are introduced, as far as these are relevant to the processes discussed. The philosophy of the book deviates from that of standard pharmaceutical textbooks, in that it focuses primarily on physical principles involved in the manufacture of dosage forms rather than describing these processes purely by observation.

Concomitantly, the fourth symposium in this series is planned in Las Vegas , July 13-17 , 199 2 . l As pointed out in the Preface to the earlier two volumes ,2, the topic of particles on surfaces is of tremendous interest and concern in a wide spectrum of technological areas . The objectives of the Third symposium were es s ent i a l ly the same as those of the earlier two and our intent her e was to provide an update on the research and development activities in the world of particles on surfaces . Apropos , there has been a deliberate attempt every time to s eek out new people to present their research results and we have been very succes s f ul in this mission.

Download or read book Adhesion Science written by Steven Abbott and published by DEStech Publications, Inc. This book was released on 2015-06-29 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explains the physics and chemistry of adhesion, surface preparation and testsPresents new strategies for formulating superior strong, weak and pressure-sensitive adhesivesIncludes access to unique electronic apps that enable numerical modeling of adhesives This technical bound book explains the basic principles of adhesion and shows how they are used to formulate and improve adhesives. The volume starts by laying out key physical and chemical concepts underlying adhesion and adhesives, including strong and weak bonds plus pressure-sensitive (PSA) across multiple polymer, metal and ceramic adherends. The ideas are expressed in clear and easily understood mathematical formulas that explain surface properties as well as "good" and "bad" adhesion, with the latter covering multiple types of adhesive failure. In this context, the book presents a detailed explanation of methods to predict, test and formulate adhesives and critically analyzes test results and traditionally accepted rules for adhesive formulation. The eBook version includes online access to a unique set of applied computer programs or "apps" that automate a wide range of adhesive formulas and enable readers to input their own data and numerically model adhesion properties in conjunction with, or prior to, chemical compounding and empirical testing. This volume constitutes a lucid and practical introduction to adhesion and adhesives appropriate for specialists at all levels.

Download or read book Particle Adhesion written by David J. Quesnel and published by CRC Press. This book was released on 2002-02-07 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whenever a curved surface interacts with another surface, the principles of adhesion are at work. From the cells in your body to the dust on your glasses, intermolecular forces cause materials to attract one another. Elastic deformations resulting from these adhesive interactions store strain that can be liberated during particle detachment. Time dependent changes in adhesion can result from plastic deformation that both increases the real effective contact area and reduces the stored energy available to assist in particle removal. Processes such as these, based on the fundamentals tenets of particle adhesion, are now finding applications across many disciplines leading to a rich and rapid development of knowledge. This book documents the use of particle adhesion concepts in a variety of disciplines. Fields as varied as the cleaning of semiconductors, to the controlling of cancer metastasis, to the abatement of environmental pollution all benefit from applications of particle adhesion concepts.

Download or read book Granular Dynamics Contact Mechanics and Particle System Simulations written by Colin Thornton and published by Springer. This book was released on 2015-09-03 with total page 195 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.
