Available in PDF, EPUB and Kindle. Book excerpt: Colloidal particle transport in porous media is observed in several natural and engineered systems and has relevant applications such as enhanced oil recovery operations, targeted drug delivery treatment, and groundwater filtration processes within soil. This thesis presents a pore-scale numerical study of particle transport through a porous bed of fixed spheres arranged in a body-centered cubic (BCC) structure. The fluid flow field through the porous bed was calculated using a combined immersed boundary-lattice Boltzmann method. Individual particle trajectories were determined using the soft-sphere discrete-element method. The effects of particle size, fluid flow rate, and adhesion strength were investigated to illustrate the primary mechanisms influencing particle migration. The BCC pore structure created paths where the fluid flowed preferentially, resembling sinusoidal corrugated channels. The fluid straining field through these channels caused inertial drift of the particles towards the channel centers via a phenomenon related to oscillatory clustering. A measure was introduced to quantify particle drift into these channels over time and was shown to compare well with theoretical models for oscillatory clustering with non-adhesive particles. In the absence of adhesive forces, larger particles and higher flow rates resulted in greater particle clustering. Long-term collisions and particle capture by fixed-bed particles were observed to limit the drift measure. Computations performed with adhesive particles showed a significant reduction in the tendency for oscillatory clustering to occur due to suspended particles being more likely to remain attached to fixed bed particles along with longer collision durations.
Download or read book Experimental and Numerical Investigations Into Fundamental Mechanisms Controlling Particle Transport in Saturated Porous Media written by Po-Chieh Liu and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A non-log-linear kinetic sub-model and corresponding micro-scale experiments are needed for better predictions. Moreover, the effects of particle-particle interaction were proven significant in certain conditions, however, the processes is still unclear. Visualization technique introduced in this research is capable to explore the controlling mechanisms in micro-scale and further provides the foundations for developing non-log-linear kinetic model, quantifying the effects of particle-particle interactions, acceleration, and other uncovered physical/chemical factors on particle transport in porous media. Advancing understanding of these factors has potential for improving the prediction of colloidal particle transport under real-world, field conditions, which can benefit many programs aimed at reducing the environmental and health impacts of colloid facilitated contaminant transport.
Download or read book Colloid Transport and Attenuation in Saturated Porous Media written by Xinyao Yang and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloids refer to particles or macromolecules with at least one dimension of 1nm 1m. A wide range of environmental particles fall within this category including microorganisms, nanoparticles, and mineral precipitates. Understanding colloid fate and transport in porous medium not only permits more effective protection of water supplies, but also allows for the development of more effective pollutant remediation strategies. Organic matter (OM) complicates colloid behaviour. To date the influence of OM on colloid mobility in porous media has been largely qualitative. This book presents research leading to the development of multiple-pulse column techniques that may be integrated with mathematical models to quantify the effects of OM on particulate colloid attenuation in saturated porous medium. Research has investigated how two groups of environmental organic compounds, humic acids and proteins, influence particulate colloid attenuation by saturated sand. Study findings may shed light on complex colloidal behaviour in organic matter impacted environment and be useful to professionals in contaminant hydrogeology, environmental remediation, and wastewater treatment.

Available in PDF, EPUB and Kindle. Book excerpt: Academic and industrial research around polymer-based colloids is huge, driven both by the development of mature technologies, e.g. latexes for coatings, as well as the advancement of new materials and applications, such as building blocks for 2D/3D structures and medicine. Edited by two world-renowned leaders in polymer science and engineering, this is a fundamental text for the field. Based on a specialised course by the editors, this book provides the reader with an invaluable single source of reference. The first section describes formation, explaining basic properties of emulsions and dispersion polymerization, microfluidic approaches to produce polymer-based colloids and formation via directed self-assembly. The next section details characterisation methodologies from microscopy and small angle scattering, to surface science and simulations. The final chapters close with applications, including Pickering emulsions and molecular engineering for materials development. A comprehensive guide to polymer colloids, with contributions by leaders in their respective areas, this book is a must-have for researchers and practitioners working across polymers, soft matter and chemical and molecular engineering.

This book was released on 2013-03-25 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lattice Boltzmann method (LBM) is a relatively new simulation technique for the modeling of complex fluid systems and has attracted interest from researchers in computational physics. Unlike the traditional CFD methods, which solve the conservation equations of macroscopic properties (i.e., mass, momentum, and energy) numerically, LBM models the fluid consisting of fictive particles, and such particles perform consecutive propagation and collision processes over a discrete lattice mesh.This book will cover the fundamental and practical application of LBM. The first part of the book consists of three chapters starting form the theory of LBM, basic models, initial and boundary conditions, theoretical analysis, to improved models. The second part of the book consists of six chapters, address applications of LBM in various aspects of computational fluid dynamic engineering, covering areas, such as thermo-hydrodynamics, compressible flows, multicomponent/multiphase flows, microscale flows, flows in porous media, turbulent flows, and suspensions.With these coverage LBM, the book intended to promote its applications, instead of the traditional computational fluid dynamic method.
