This book was released on 2012-12-06 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fourth Nishinomiya-Yukawa Memorial Symposium, devoted to the topic of dynamics and patterns in complex fluids, was held on October 26 and 27, 1989, in Nishinomiya City, Japan, where ten invited speakers gave their lectures. A one-day meeting, comprising short talks and poster sessions, was then held on the same topic on October 28 at the Research Institute for Fundamental Physics, Kyoto University. The present volume contains the 10 invited papers and 38 contributed papers presented at these two meetings. The symposium was sponsored by Nishinomiya City, where Prof. Hideki Yukawa once lived and where he wrote the celebrated paper describing the work that was later honored by a Nobel prize. The topic of the fourth symposium was chosen from one of the most vigorously evolving and highly interdisciplinary fields in condensed matter physics. The field of complex fluids is very diverse and still in its infancy and, as a result, the definition of a complex fluid varies greatly from one researcher to the next. One of the objectives of the symposium was to clarify its definition by explicitly posing a number of potentially rich problems waiting to be explored. Indeed, experimentalists are disclosing a variety of intriguing dynamical phenomena in complex systems such as polymers, liquid crystals, gels, colloids, and surfactant systems. We, the organizers, hope that the symposium will contribute to the increasing importance of the field in the coming years.

Book excerpt: The present thesis is devoted to the dynamics of specific complex fluids. On the one hand we studythe dynamics of the so-called nematic liquid crystals, through the models proposed by Ericksen and Leslie, Beris and Edwards, Qian and Sheng.On the other hand we analyze the dynamics of a temperature-dependent complex fluid, whose dynamics is governed by the Boussinesq system.Nematic liquid crystals are materials exhibiting a state of matter between an ordinary fluid and a solid. In this thesis we are interested in studying the Cauchy problem associated to eachsystem modelling their hydrodynamics. At first, we establish some well-posedness results, such asexistence and uniqueness of global-in-time weak or classical solutions. Moreover we also analyzesome dynamical behaviours of these solutions, such as propagations of both higher and lowerregularities.The general framework for the initial data is that of Besov spaces, which extend the most widelyknown classes of Sobolev and Hölder spaces.The Ericksen-Leslie system is studied in a simplified form proposed by F. Lin and C. Liu,which retains the main difficulties of the original one. We consider both a two-dimensional and athree-dimensional space-domain. We assume the density to be no constant, i.e. the inhomogeneouscase, moreover we allow it to present discontinuities along an interface so that we can describe amixture of liquid crystal materials with different densities. We prove the existence of global-in-timeweak solutions under smallness conditions on the initial data in critical homogeneous Besov spaces.These solutions are invariant under the scaling behaviour of the system. We also show that theuniqueness holds under a tiny extra-regularity for the initial data.The Beris-Edwards system is analyzed in a two-dimensional space-domain. We achieve existenceand uniqueness of global-in-time weak solutions when the initial data belongs to specific Sobolevspaces (without any smallness condition). The regularity of these functional spaces is suitable inorder to well define a weak solution. We achieve the uniqueness result through a specific analysis,controlling the norm of the difference between to weak solutions and performing a delicate doublelogarithmicestimate. Then, the uniqueness holds thanks to the Osgood lemma. We also achieve aresult about regularity propagation.The Qian-Sheng model is analyzed in a space-domain with dimension greater or equal than two.In this case, we emphasize some important characteristics of the system, especially the presence ofan inertial term, which generates significant difficulties. We perform the existence of a Lyapunovfunctional and the existence and uniqueness of classical solutions under a smallness condition forthe initial data.Finally we deal with the well-posedness of the Boussinesq system. We prove the existence ofglobal-in-time weak solutions when the space-domain has a dimension greater or equal than two.We deal with the case of a viscosity dependent on the temperature. The initial temperature is justsupposed to be bounded, while the initial velocity belongs to some critical Besov Space. The initialdata have a large vertical component while the horizontal components fulfil a specific smallnessconditions: they are exponentially smaller than the vertical component.

Available in PDF, EPUB and Kindle. Book excerpt: No-one who took part in the NATO Advanced Studies Institute from which this book emerges will have forgotten the experience. True, the necessary conditions for a very successful workshop were satisfied: a field of physics bursting with new power and new puzzles, a matchless team of lecturers, an international gathering of students many of whom had themselves contributed at the forefront of their subject, an admirable overlap of experiment and theory, a good mix of experimenters and theorists, an enviable environment. But who could have foreseen the way the workshop became a focus for future directions, how fresh scientific ideas tumbled out of the discussion periods, how the context of teaching the field produced such fruitfulness of research at the highest level? The organisers did have some specific aims in mind. Perhaps foremost was the desire to compare notes among different areas within the sub field of soft condensed matter physics fast becoming known as "complex fluids". For readers seeking a definition, the prosaic "fluids with bits in" can be passed rapidly over in favour of the elegant discussion of slow variables by Scott Milner in his chapter. The uniting goals of the subject are to model the essential molecular or mesoscopic structure theoretically, and to probe this structure as well as the bulk response of the system experimentally. Our famous examples were: colloids, polymers, liquid crystals, block co-polymers and self-assembling surfactant systems.

Download or read book Mathematical Modeling for Complex Fluids and Flows written by Michel Deville and published by Springer Science & Business Media. This book was released on 2012-01-13 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Drop Bubble and Particle Dynamics in Complex Fluids written by Pengtao Yue and published by MDPI. This book was released on 2020-03-19 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of drops, bubbles, and particles affects the behavior and response of complex multiphase fluids. In many applications, these complex fluids have more than one non-Newtonian component, e.g., polymer melts, liquid crystals, and blood plasma. In fact, most fluids exhibit non-Newtonian behaviors, such as yield stress, viscoelastity, viscoplasticity, shear thinning, or shear thickening, under certain flow conditions. Even in the complex fluids composed of Newtonian components, the coupling between different components and the evolution of internal boundaries often lead to a complex rheology. Thus the dynamics of drops, bubbles, and particles in both Newtonian fluids and non-Newtonian fluids are crucial to the understanding of the macroscopic behavior of complex fluids. This Special Issue aims to gather a wide variety of papers that focus on drop, bubble and particle dynamics in complex fluids. Potential topics include, but are not limited to, drop deformation, rising drops, pair-wise drop interactions, drop migration in channel flows, and the interaction of particles with flow systems such as pastes and slurries, glasses, suspensions, and emulsions. We emphasize numerical simulations, but also welcome experimental and theoretical contributions.

Download or read book Optical Rheometry of Complex Fluids written by Gerald G. Fuller and published by Oxford University Press. This book was released on 1995-06-29 with total page 283 pages. 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.
