Available in PDF, EPUB and Kindle. Book excerpt: This report describes work performed under grant No. DE-FG03-88ER13911 for the period June 15, 1988 through June 14, 1989. During this time, significant progress was made in the derivation of the fundamental equations describing suspensions and multicomponent fluid flow. We first considered a system consisting of spherical heavy (Brownian) particles immersed in a bath of spherical particles. The deviations of the bath from equilibrium are due to the nonequilibrium motions of the Brownian particles. The densities of the bath and of a Brownian particle are similar. An expansion in powers of the mass ratio, yields a Fokker-Planck equation for the distribution function of the Brownian particles, including the effects of direct and hydrodynamic interactions amongst these particles. The effect of the Brownian particle motion on the bath properties has been described. The conditions under which a closed equation for the coordinate space distribution function, can be obtained have been investigated and a Smoluchowski equation for this quantity has been derived.

Available in PDF, EPUB and Kindle. Book excerpt: Advancement in computational capacity combined with the emergence of efficient algorithmshas made the computational studies very powerful and desirable. Despite the greatimportance of complex fluids such as emulsions, colloidal suspensions, and gels in manyapplications, some of their physical and mechanical properties remain poorly understood.To understand rheological and mechanical properties of such systems, one needs tounderstand their properties at different time and length scales through careful multiscaleanalysis. To answer these questions, we use Dissipative Particle Dynamics as a versatilecoarse-grained method to gain a better understanding of different scales and bridge the gapbetween the microscopic and macroscopic worlds in particulate multicomponent complexfluids.In Chapter 1, briefly, we introduce the DPD mathematical and physical formalism. InChapter 2, we examine different algorithms to measure the transport properties of a simpleDPD fluid and introduce the new computational method to measure the viscosity of DPD liquids under non-equilibrium conditions to account for the numerical instabilities. InChapter 3, we discuss the properties of multiphasic systems mainly liquids in liquids. Weinvestigate the effect of molecular composition, configuration, and conformability ofsurface active molecules in stabilizing immiscible mixtures for flat interfaces as well ascurved interfaces. The final section of chapter 3 is dedicated to studying the effect of sheardeformation on the geometrical evolution of surfactant covered nanodroplets. In chapter4, we mainly focus on colloidal suspensions and their rheological responses in nonlineardeformation. Through network analysis, we show that the frictional bonds form a percolatednetwork at volume fractions close to jamming while at volume fractions well belowjamming the frictional networks are transient and unstable. Measuring viscosity and normalstresses show the discontinuous transition occurs in the viscosity and positive values forthe first normal stress which is concomitant with the formation of the percolated network.In Chapter 5, we look at mechanistic behavior of colloidal particles with short-rangedattraction potential. We observe a two-step yielding transition under start-up deformationand explained it through careful analysis of the microstructure. It was shown thathydrodynamic interactions are important to explain this behavior at high deformation rates.

Available in PDF, EPUB and Kindle. Book excerpt: Written by the leading experts in the field, this book will provide a valuable, current account of the advances in the measurement and prediction of transport properties that have occurred over the last twenty years. Critical to industry, these properties are fundamental to, for example, the development of fossil fuels, carbon sequestration and alternative energy sources. This unique and comprehensive account will provide the experimental and theoretical background of near-equilibrium transport properties which provide the background when investigating industrial applications. Coverage includes new experimental techniques and how existing techniques have developed, new fluids eg molten metals, dense fluids, and critical enhancements of transport properties of pure substances. Practitioners and researchers in chemistry and engineering will benefit from this state of the art record of recent advances in the field of transport properties.

This Special Issue of Fluids is dedicated to the recent advances in the mathematical and physical modeling of non-linear fluids with industrial applications, especially those concerned with CFD studies. These fluids include traditional non-Newtonian fluid models, electro- or magneto-rheological fluids, granular materials, slurries, drilling fluids, polymers, blood and other biofluids, mixtures of fluids and particles, etc.

Download or read book Multicomponent Diffusion written by E. L. Cussler and published by Elsevier. This book was released on 2013-10-22 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multicomponent Diffusion discusses the multicomponent diffusion of the three phases of matter. The book is comprised of nine chapters that cover studies of multicomponent diffusion and mass transfer with an emphasis on the chemical characteristics responsible for multicomponent diffusion. Chapter 1 provides an introductory discourse about multicomponent diffusion. Chapter 2 discusses binary diffusion, while Chapter 3 covers multicomponent flux equation. The measurement of ternary diffusion and the estimation of ternary diffusion coefficients are also explained in the book. A chapter then covers the interacting systems, and the subsequent chapter talks about membranes without mobile carriers. The text also discusses carrier-containing membranes and the multicomponent mass transfer. The book will be of great use to researchers and professionals whose work requires a good understanding of multicomponent diffusion.

Available in PDF, EPUB and Kindle. Book excerpt: In this monograph, the density ?uctuation theory of transport coe?cients of simple and complex liquids is described together with the kinetic theory of liquids, the generic van der Waals equation of state, and the modi?ed free volume theory. The latter two theories are integral parts of the density ?- tuation theory, which enables us to calculate the density and temperature dependence of transport coe?cients of liquids from intermolecular forces. The terms nanoscience and bioscience are the catch phrases currently in fashion in science. It seems that much of the fundamentals remaining unsolved or poorly understood in the science of condensed matter has been overshadowed by the frenzy over the more glamorous disciplines of the former, shunned by novices, and are on the verge of being forgotten. The transport coe?cients of liquids and gases and related thermophysical properties of matter appear to be one such area in the science of macroscopic properties of molecular systems and statisticalmechanicsofcondensedmatter. Evennano-andbiomaterials,h- ever, cannot be fully and appropriately understood without ?rm grounding and foundations in the macroscopic and molecular theories of transport pr- ertiesandrelatedthermophysicalpropertiesofmatterinthecondensedphase.

Available in PDF, EPUB and Kindle. Book excerpt: The corresponding-states principle helps the understanding and calculating of thermodynamic, transport, and surface properties of substances in various states, required by our modern lifestyle. The Corresponding-States Principle and its Practice: Thermodynamic, Transport and Surface Properties of Fluids describes the origins and applications of the principle from a universal point of view with comparisons to experimental data where possible. It uses the universal theory to explain present theories. Emphasis is on the properties of pure systems, and the corresponding-states theory can also be extended to mixtures, which are treated as pure systems. Furthermore, the author discusses current progress, and shows technicians how to derive practical equations from molecular modeling. The Corresponding-States Principle and its Practice: Thermodynamic, Transport and Surface Properties of Fluids is the ideal handbook for those in chemical science and engineering related to energy, environment, natural gas, and petroleum.* Describes the origins and applications from a universal viewpoint* Includes experimental data for comparisons * Suitable for researchers, applied engineers, and those interested in the corresponding states theory
