Available in PDF, EPUB and Kindle. Book excerpt: Rheology is a component of Encyclopedia of Chemical Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Rheology is the study of the flow of matter. It is classified as a physics discipline and focuses on substances that do not maintain a constant viscosity or state of flow. That can involve liquids, soft solids and solids that are under conditions that cause them to flow. It applies to substances which have a complex molecular structure, such as muds, sludges, suspensions, polymers and other glass formers, as well as many foods and additives, bodily fluids and other biological materials. The theme on Rheology focuses on five main areas, namely, basic concepts of rheology; rheometry; rheological materials, rheological processes and theoretical rheology. Of course, many of the chapters contain material from more than one general area. Rheology is an interdisciplinary subject which embraces many aspects of mathematics, physics, chemistry, engineering and biology. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Download or read book Out-of-equilibrium Soft Matter written by Christina Kurzthaler and published by Royal Society of Chemistry. This book was released on 2023-03-24 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term active fluids refers to motions that are created by transforming energy from the surroundings into directed motion. There are many examples, both natural and synthetic, including individual swimming bacteria or motile cells, drops and bubbles that move owing to surface stresses (so-called Marangoni motions), and chemical- or optical-driven colloids. Investigations into active fluids provide new insights into non-equilibrium systems, have the potential for novel applications, and open new directions in physics, chemistry, biology and engineering. This book provides an expert introduction to active fluids systems, covering simple to complex environments. It explains the interplay of chemical processes and hydrodynamics, including the roles of mechanical and rheological properties across active fluids, with reference to experiments, theory, and simulations. These concepts are discussed for a variety of scenarios, such as the trajectories of microswimmers, cell crawling and fluid stirring, and apply to collective behaviours of dense suspensions and active gels. Emerging avenues of research are highlighted, ranging from the role of active processes for biological functions to programmable active materials, showcasing the exciting potential of this rapidly-evolving research field.

Available in PDF, EPUB and Kindle. Book excerpt: We present a new algorithm to simulate unsteady viscoelastic flows in abrupt contraction channels. In our approach we split the viscoelastic terms of the Oldroyd-B constitutive equation using Duhamel's formula and discretize the resulting PDEs using a semi-implicit finite difference method based on a Lax-Wendroff method for hyperbolic terms. In particular, we leave a small residual elastic term in the viscous limit by design to make the hyperbolic piece well-posed. A projection method is used to impose the incompressibility constraint. We are able to compute the full range of elastic flows in an abrupt contraction channel--from the viscous limit to the elastic limit--in a stable and convergent manner for elastic Mach numbers less than one. We demonstrate the method for unsteady Oldroyd-B and Maxwell fluids in planar contraction channels.

Download or read book Microscopic Flow of Viscoelastic Wormlike Micellar Solutions Through Contraction Geometries written by Emad Jafari Nodoushan and published by . This book was released on 2020 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viscoelastic fluids are commonly used in many engineering applications such as in polymer processing industry, enhanced oil recovery and inkjet printing. Viscoelastic contraction flow represents the most common flow condition in those applications, but the flow is associated with its inherent problems such as additional pressure drops and flow instabilities. It is well known that formation of secondary flows at the upstream corners of the contraction greatly influences the fluidic behavior and promotes the flow instabilities. Therefore, investigating the flow conditions that induce the secondary flow has been an extensive research subject with the ultimate goal of elucidating the kinematics of viscoelastic contraction flows. Several relevant studies concluded that formation of secondary flow is influenced greatly by the elastic stress associated with the viscoelastic flow. Non-dimensional numbers that estimates the ratio of elastic stress to viscous (Wi and De numbers) or inertial (El number) stress has been used to quantify the effect of elasticity on the viscoelastic flow behavior. Even though a general consensus has been established that the higher elastic stress promoted the formation and enhancement of secondary flow, quite different flow behaviors were reported for the different fluids at the same level of elastic stress. Additionally, comparable secondary flows were also observed at different levels of elastic stresses. It should be noted that these non-dimensional numbers could not solely characterize the behavior of viscoelastic contraction flow. In this study, in addition to the role of elastic stress, the contribution of shear dependent rheology and extensional characteristics of the viscoelastic test fluids to the contraction fluidic behavior has been investigated experimentally. Wormlike micellar solutions (WMS) were chosen as the viscoelastic test fluids in virtue of their advantageous characteristics over polymer solutions and their growing applications. The shear and extensional rheology of the test fluids were characterized, and the velocity and shear deformation profiles associated with their contraction flow were quantitatively measured.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This open access book, published in the Soft and Biological Matter series, presents an introduction to selected research topics in the broad field of flowing matter, including the dynamics of fluids with a complex internal structure -from nematic fluids to soft glasses- as well as active matter and turbulent phenomena. Flowing matter is a subject at the crossroads between physics, mathematics, chemistry, engineering, biology and earth sciences, and relies on a multidisciplinary approach to describe the emergence of the macroscopic behaviours in a system from the coordinated dynamics of its microscopic constituents. Depending on the microscopic interactions, an assembly of molecules or of mesoscopic particles can flow like a simple Newtonian fluid, deform elastically like a solid or behave in a complex manner. When the internal constituents are active, as for biological entities, one generally observes complex large-scale collective motions. Phenomenology is further complicated by the invariable tendency of fluids to display chaos at the large scales or when stirred strongly enough. This volume presents several research topics that address these phenomena encompassing the traditional micro-, meso-, and macro-scales descriptions, and contributes to our understanding of the fundamentals of flowing matter. This book is the legacy of the COST Action MP1305 “Flowing Matter”.
