This important and timely book deals with the theoretical and experimental investigation of the phase transitions which occur in complex fluid systems, namely lyotropic systems, microemulsions, colloids, gels, polymers, biological membranes, Langmuir monolayers, and ferrofluids. It contains 20-odd review papers from the major contributors to this rapidly growing field of research, summarizing the main results obtained in the description and understanding of the phase transitions taking place between the isotopic, nematic, cholesteric, lamellar, hexagonal, and cubic mesophases of complex fluids.
Nevertheless, experiments show that the viscosity is no more constant for many
others fluids, such as pastes or polymer solutions. These fluids are called non-
Newtonian or complex fluids. Measurements showed that the viscosity varies

This book serves as an introduction to the continuum mechanics and mathematical modeling of complex fluids in living systems. The form and function of living systems are intimately tied to the nature of surrounding fluid environments, which commonly exhibit nonlinear and history dependent responses to forces and displacements. With ever-increasing capabilities in the visualization and manipulation of biological systems, research on the fundamental phenomena, models, measurements, and analysis of complex fluids has taken a number of exciting directions. In this book, many of the world’s foremost experts explore key topics such as: Macro- and micro-rheological techniques for measuring the material properties of complex biofluids and the subtleties of data interpretation Experimental observations and rheology of complex biological materials, including mucus, cell membranes, the cytoskeleton, and blood The motility of microorganisms in complex fluids and the dynamics of active suspensions Challenges and solutions in the numerical simulation of biologically relevant complex fluid flows This volume will be accessible to advanced undergraduate and beginning graduate students in engineering, mathematics, biology, and the physical sciences, but will appeal to anyone interested in the intricate and beautiful nature of complex fluids in the context of living systems.

A self-contained textbook, Microhydrodynamics and Complex Fluids deals with the main phenomena that occur in slow, inertialess viscous flows often encountered in various industrial, biophysical, and natural processes. It examines a wide range of situations, from flows in thin films, porous media, and narrow channels to flows around suspended particles. Each situation is illustrated with examples that can be solved analytically so that the main physical phenomena are clear. It also discusses a range of numerical modeling techniques. Two chapters deal with the flow of complex fluids, presented first with the formal analysis developed for the mechanics of suspensions and then with the phenomenological tools of non-Newtonian fluid mechanics. All concepts are presented simply, with no need for complex mathematical tools. End-of-chapter exercises and exam problems help you test yourself. Dominique Barthès-Biesel has taught this subject for over 15 years and is well known for her contributions to low Reynolds number hydrodynamics. Building on the basics of continuum mechanics, this book is ideal for graduate students specializing in chemical or mechanical engineering, material science, bioengineering, and physics of condensed matter.
The design and the engineering of new materials like polymers, plastics,
ceramics, foams, etc., have produced complex fluids because the materials
processing based on extrusion, molding, blowing, etc. is using them in the fluid

Mathematical Modeling for Complex Fluids and Flows provides researchers and engineering practitioners encountering fluid flows with state-of-the-art knowledge in continuum concepts and associated fluid dynamics. In doing so it supplies the means to design mathematical models of these flows that adequately express the engineering physics involved. It exploits the implicit link between the turbulent flow of classical Newtonian fluids and the laminar and turbulent flow of non-Newtonian fluids such as those required in food processing and polymeric flows. The book develops a descriptive mathematical model articulated through continuum mechanics concepts for these non-Newtonian, viscoelastic fluids and turbulent flows. Each complex fluid and flow is examined in this continuum context as well as in combination with the turbulent flow of viscoelastic fluids. Some details are also explored via kinetic theory, especially viscoelastic fluids and their treatment with the Boltzmann equation. Both solution and modeling strategies for turbulent flows are laid out using continuum concepts, including a description of constructing polynomial representations and accounting for non-inertial and curvature effects. Ranging from fundamental concepts to practical methodology, and including discussion of emerging technologies, this book is ideal for those requiring a single-source assessment of current practice in this intricate yet vital field.

This book provides a self-contained presentation of optical methods used to measure the structure and dynamics of complex fluids subject to the influence of external fields. Such fields--hydrodynamic, electric, and magnetic--are commonly encountered in both academic and industrial research, and can produce profound changes in the microscale properties of liquids comprised of polymers, colloids, liquid crystals, or surfactants. Starting with the basic Maxwell field equations, this book discusses the polarization properties of light, including Jones and Mueller calculus, and then covers the transmission, reflection, and scattering of light in anisotropic materials. Spectroscopic interactions with oriented systems such as absorptive dichroism, small wide angle light scattering, and Raman scattering are discussed. Applications of these methods to a wide range of problems in complex fluid dynamics and structure are presented, along with selected case studies chosen to elucidate the range of techniques and materials that can be studied. As the only book of its kind to present a self-contained description of optical methods used for the full range of complex fluids, this work will be special interest to a wide range of readers, including chemical engineers, physical chemists, physicists, polymer and colloid scientists, along with graduate and post-graduate researchers.

Chemical enhanced oil recovery methods have significant potential to improve oil recovery after waterflooding. It is relatively easy to improve recovery in the lab under controlled conditions. However, field-scale implementations do not yield the same recovery results for a variety of reasons that include different mixing levels from the lab to the field, and also that species travel at different velocities. Moreover, the modeling of physicochemical phenomena, which are involved in the process, can be inaccurate or lack predictive capabilities. Such phenomena include phase behavior, viscosity, and reaction kinetics modeling. In this dissertation, we present modeling improvements and a better understanding of those physicochemical processes. The improvements will help to model accurately and to design successfully improved oil recovery scenarios. This dissertation presents the following research outcomes to model physicochemical phenomena involved in chemical enhanced oil recovery. Chapter I covers introductory remarks on chemical enhanced oil recovery. Chapter II focusses on the experimental study of alkali-cosolvent phase behavior using acidic crude oil. We study the possibility of using alkali for in situ surfactant generation, over costly synthetic surfactants. The chapter proposes a mechanism that explains the formation of water-in-oil macroemulsion, which is traditionally overlooked. Chapter III discusses an updated flash calculation algorithm with variable characteristic length in microemulsion phase. Chapter VI presents a microemulsion phase behavior equation of state algorithm that accounts for equilibrium K-values, and surfactant partitioning. For the first time, we propose equations to constrain the size of two-phase lobes. These constraints are based on constant K-value limiting conditions. Chapter V presents a compositional viscosity model for microemulsion systems. We present a 'viscosity map' approach that accounts for the percolation threshold locus in compositional space. The compositional aspect of microemulsion viscosity is typically overlooked in the literature. Chapter VI is focused on modeling the effects of reaction kinetics and dispersion during low salinity waterflooding. Reaction kinetics is typically ignored in reservoir simulation. We show that oil recovery is affected when reaction kinetics is included in the modeling, for example, recovery fronts are delayed based on the ratio of convection and reaction rates. Chapter VII concludes this dissertation. The common theme of this dissertation addresses the thermodynamics of complex fluids in the context of chemical enhanced oil recovery.

Most problems in science involve many scales in time and space. An example is turbulent ?ow where the important large scale quantities of lift and drag of a wing depend on the behavior of the small vortices in the boundarylayer. Another example is chemical reactions with concentrations of the species varying over seconds and hours while the time scale of the oscillations of the chemical bonds is of the order of femtoseconds. A third example from structural mechanics is the stress and strain in a solid beam which is well described by macroscopic equations but at the tip of a crack modeling details on a microscale are needed. A common dif?culty with the simulation of these problems and many others in physics, chemistry and biology is that an attempt to represent all scales will lead to an enormous computational problem with unacceptably long computation times and large memory requirements. On the other hand, if the discretization at a coarse level ignoresthe?nescale informationthenthesolutionwillnotbephysicallymeaningful. The in?uence of the ?ne scales must be incorporated into the model. This volume is the result of a Summer School on Multiscale Modeling and S- ulation in Science held at Boso ¤n, Lidingo ¤ outside Stockholm, Sweden, in June 2007.

Presenting a unified approach, this book focusses on the concepts and theoretical methods that are necessary for an understanding of the physics and chemistry of the fluid state. The authors do not attempt to cover the whole field in an encyclopedic manner. Instead, important ideas are presented in a concise and rigorous style, and illustrated with examples from both simple molecular liquids and more complex soft condensed matter systems such as polymers, colloids, and liquid crystals.
