Available in PDF, EPUB and Kindle. Book excerpt: The hydrodynamics of colloids in confined geometries is studied hierarchically beginning with the exact solutions for a spherical particle translating, rotating and deforming in the presence of a plane wall at low Reynolds number. The many-bodied hydrodynamic interactions among a collection of spherical particles near a plane wall are computed and used to study the Brownian motion of confined suspensions. The method of reflections is used to describe the motion of a single spherical particle embedded in the fluid constrained by two, parallel plane walls. From this, tables which are independent of the channel width are generated describing the particle's response to various force moments. This same approach is expanded to describe the hydrodynamic interactions among the particles comprising a colloidal dispersion confined in a channel. The simulations arising from this theory depict the short-time self-diffusivity, sedimentation rate and high frequency viscosity of suspensions of varying volume fractions in channels of varying widths. A theory for the scattering of evanescent waves by colloidal dispersions is developed and cast in the form of the diffusivity measured by classical light scattering. A series of simulations is conducted to predict the short- time self-diffusivity and the collective diffusivity measured by evanescent wave dynamic light scattering. The thesis concludes with a discussion of how the developed simulations and theories can be extended to make dynamic measurements as well as a brief consideration of some remaining, open questions.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The hydrodynamic interaction among constituents of a complex fluid is sensitive to any change in the boundary conditions. Hence the response of a confined complex fluid to the applied stress is quite different from that of an unbounded complex fluid. In this thesis, using numerical simulations, we investigate the dynamics of suspensions in two different types of confinement. The rheology of dense colloidal suspensions changes drastically upon the modification in the surface properties of the particles. We used lattice Boltzmann simulations to investigate the the effects of polymer coatings on the squeezing flow between parallel plates. In this study, we used random arrays of stationary and mobile particles as the simplest models of the polymer coat.
Book Synopsis Accelerated Lattice Boltzmann Model for Colloidal Suspensions by : Hassan Farhat
Download or read book Accelerated Lattice Boltzmann Model for Colloidal Suspensions written by Hassan Farhat and published by Springer Science & Business Media. This book was released on 2014-04-12 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloids are ubiquitous in the food, medical, cosmetics, polymers, water purification, and pharmaceutical industries. The thermal, mechanical, and storage properties of colloids are highly dependent on their interface morphology and their rheological behavior. Numerical methods provide a convenient and reliable tool for the study of colloids. Accelerated Lattice Boltzmann Model for Colloidal Suspensions introduce the main building-blocks for an improved lattice Boltzmann–based numerical tool designed for the study of colloidal rheology and interface morphology. This book also covers the migrating multi-block used to simulate single component, multi-component, multiphase, and single component multiphase flows and their validation by experimental, numerical, and analytical solutions. Among other topics discussed are the hybrid lattice Boltzmann method (LBM) for surfactant-covered droplets; biological suspensions such as blood; used in conjunction with the suppression of coalescence for investigating the rheology of colloids and microvasculature blood flow. The presented LBM model provides a flexible numerical platform consisting of various modules that could be used separately or in combination for the study of a variety of colloids and biological flow deformation problems.

Book Synopsis Colloidal Suspension Rheology by : Jan Mewis
Download or read book Colloidal Suspension Rheology written by Jan Mewis and published by Cambridge University Press. This book was released on 2011-11-17 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloidal suspensions are encountered in a multitude of natural, biological and industrially relevant products and processes. Understanding what affects the flow behaviour, or rheology, of colloid particles, and how these suspensions can be manipulated, is important for successful formulation of products such as paint, polymers, foods and pharmaceuticals. This book is the first devoted to the study of colloidal rheology in all its aspects. With material presented in an introductory manner, and complex mathematical derivations kept to a minimum, the reader will gain a strong grasp of the basic principles of colloid science and rheology. Beginning with purely hydrodynamic effects, the contributions of Brownian motion and interparticle forces are covered, before the reader is guided through specific problem areas, such as thixotropy and shear thickening; special classes of colloid suspensions are also treated. On line resources include: questions and solutions for self-study, updates, and links to further resources.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, we present a computational study of the rheology and dynamics of spherically-confined polydisperse suspensions of hydrodynamically interacting colloids, a simple model system that provides an important framework for studying the behavior of living and non-living confined colloidal suspensions. Colloids are microscopically small particles suspended in a solvent. Examples include the cytoplasm of biological cells, micro-reactor vesicles, and particle-laden droplets ubiquitous in additive manufacturing and industrial coatings. Here we present an extension of the Confined Stokesian Dynamics algorithm (CSD) capable of modeling the bulk rheology of confined colloidal suspensions of arbitrary particle-size distribution, at and away from equilibrium. We will present novel hydrodynamic functions we developed that couple particle dynamics to suspension properties and, after a brief overview of the CSD algorithm, the results of a systematic study of the impact of changes in confinement and size polydispersity on equilibrium structure and dynamics. We showed that an interplay between polydispersity and confinement reveals demixing and localized dynamics that help explain our previous discovery that such dynamics control the speedup of protein synthesis in faster-growing bacteria. Next, we will present a new theoretical framework we developed for measuring the intrinsic viscosity and osmotic pressure in confined suspensions. The first significant outcome of this work was that tighter confinement and crowding significantly increase equilibrium viscous dissipation and osmotic pressure compared to unconfined suspensions. This result is important for the rational design of biochemical tests, where up to now, only the effect of passive crowders was taken into account. The second significant outcome of this work was the modeling of strong departures from equilibrium, including a representation of biomolecules localized at one pole of the cavity that subsequently diffuse - mimicking the Min cycle in E. coli our work shows that concentration gradients inside cells increase the residence time of proteins close to the membrane, which is beneficial for Min-protein membrane reaction kinetics that promotes correct cell division. Finally, we will present three other significant theoretical developments in the field of microhydrodynamics done in service of the underlying theoretical framework of our model.
