Book excerpt: Debris flows are among the most frequent and destructive of all geomorphic processes, mainly affecting mountainous areas in a range of morphoclimatic environments, and the damage they cause is often devastating. Increased anthropisation calls for improvements in the criteria used to identify debris-flow risk areas and the prevention measures adopted. One of the main difficulties encountered by the approaches illustrated in previous literature is linked to their possible validation either in the field or in a laboratory environment. The choice of a rheological model is extremely important. This book provides methodological details, which can be applied to investigations on debris-flow mechanics, capable of providing an accurate representation of the phenomenology.

Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2020 in the subject Chemistry - Other, grade: Research, , course: Research, language: English, abstract: A detailed study of the theological modelling of composite propellant slurry based on hydroxyl terminated polybutadiene (HTPB) prepolymer, Dioctyl adipate (DOA) plasticizer, toluene diisocynate curative, ammonium per chlorate (AP) oxidizer and aluminium powder as a metallic fuel is carried out and studied the effect of each of the ingredients on the composite propellant slurry (cps). The effect of temperature on viscosity of polymer and plasticizer system was studied at different temperatures, and torques (shear force). The polymer hydroxyl terminated polybutadiene (HTPB) and plasticizer (DOA) viscosity data showed temperature dependence and independent of the torque (i.e. shear force). Therefore, the viscosity data has been modelled to polynomial model of a fourth order with temperature for polymer and plasticizer. The results showed good agreement between theory and experiment. These polynomial model results have been compared with Arrhenius model. The polynomial model showed better comparison within ± 4 % error compared to Arrhenius model with ± 4 to ± 22 % error over the temperature range of 30 - 70 °C. The viscosity of the mixture was also studied at different weight fractions of the polymer:plasticizer. The viscosity of mixture showed dependence on the weight fraction of the plasticizer and temperature. Rheology concerns itself with the mechanism of flow and deformation of matter. Deformation is a phenomenon, which is associated with a volume element. This term was invented by Prof. Bingham of Lafayette College, Indiana. Significant advances have been made in polymer rheology, in bio-rheology and in suspension rheology. There has been a significant appreciation of the importance of rheology in the chemical processing industry like medicine, paints and printing ink technology etc. and biotechnological industries. It has also made important contributions in food technology, building and structural engineering, cosmetics, drilling operations and oil wells etc.

Available in PDF, EPUB and Kindle. Book excerpt: In an earlier book, Rheological Measurement (A. A. Collyer & D. W. Clegg, Elsevier Applied Science, 1988), the basic rheological methods of measurement presently used were discussed in the light of the basic underlying principles and current theories. The same approach is adopted in this companion book, which is concerned with some newer or more sophisticated techniques that have resulted from a fresh understanding of the subject, or as a result of improvement in computer control, data acquisition and computational power, or more simply from an industrial need, particularly with regard to process control. The first two chapters deal with the extensional flow properties of fluids and their measurement. This inclusion is in response to a greater awareness in industry of the importance of these flows. Chapter 3 intro duces and develops the subject of surface rheology and the measurement of its properties, again a subject of increasing significance. The methods of measurement of the dynamic mechanical properties of fluids and the calculation of the resulting rheological parameters are discussed in Chap ters 4-7 inclusive. The subject areas covered are: large-amplitude oscilla tory shear, a model for viscoelastic fluids and solids, a new method of measuring dynamic mechanical properties, particularly for curing sys tems, and the use of complex waveforms in dynamic mechanical analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Modern day high-performance computers are making available to 21st-century scientists solutions to rheological flow problems of ever-increasing complexity. Computational rheology is a fast-moving subject — problems which only 10 years ago were intractable, such as 3D transient flows of polymeric liquids, non-isothermal non-Newtonian flows or flows of highly elastic liquids through complex geometries, are now being tackled owing to the availability of parallel computers, adaptive methods and advances in constitutive modelling.Computational Rheology traces the development of numerical methods for non-Newtonian flows from the late 1960's to the present day. It begins with broad coverage of non-Newtonian fluids, including their mathematical modelling and analysis, before specific computational techniques are discussed. The application of these techniques to some important rheological flow problems of academic and industrial interest is then treated in a detailed and up-to-date exposition. Finally, the reader is kept abreast of topics at the cutting edge of research in computational applied mathematics, such as adaptivity and stochastic partial differential equations.All the topics in this book are dealt with from an elementary level and this makes the text suitable for advanced undergraduate and graduate students, as well as experienced researchers from both the academic and industrial communities.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides a comprehensive and self-contained treatment of continuum physics, illustrating a systematic approach to the constitutive equations for wide-ranging classes of materials. Derivations of results are detailed through careful proofs, and the contents have been developed to ensure a self-contained and consistent presentation. Part I reviews the kinematics of continuous bodies and illustrates the general setting of balance laws. Essential preliminaries to continuum physics – such as reference and current configurations, transport relations, singular surfaces, objectivity, and objective time derivatives – are covered in detail. A chapter on balance equations then develops the balance laws of mass, linear momentum, angular momentum, energy, and entropy, as well as the balance laws in electromagnetism. Part II is devoted to the general requirements on constitutive models, emphasizing the application of objectivity and consistency with the second law of thermodynamics. Common models of simple materials are then reviewed, and in this framework, detailed descriptions are given of solids (thermoelastic, elastic, and dissipative) and fluids (elastic, thermoelastic, viscous, and Newtonian). A wide of variety of constitutive models are investigated in Part III, which consists of separate chapters focused on several types of non-simple materials: materials with memory, aging and higher-order grade materials, mixtures, micropolar media, and porous materials. The interaction of the electromagnetic field with deformation is also examined within electroelasticity, magnetoelasticity, and plasma theory. Hysteretic effects and phase transitions are considered in Part IV. A new approach is established by treating entropy production as a constitutive function in itself, as is the case for entropy and entropy flux. This proves to be conceptually and practically advantageous in the modelling of nonlinear phenomena, such as those occurring in hysteretic continua (e.g., plasticity, electromagnetism, and the physics of shape memory alloys). Mathematical Modelling of Continuum Physics will be an important reference for mathematicians, engineers, physicists, and other scientists interested in research or applications of continuum mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: There are few comprehensive books on the market on the subject of Rheology -- the complex science dealing with flow and deformation of matter -- and these are several years old. At least now there is a book that explains the meaning of a science that many scientists need to use but only a few can fully grasp. It does so by striking the balance between oversimplification and overload of theory in a very compelling and readable manner. The authors' systematic presentation enables the authors to include all components of Rheology in one volume. The first four chapters of this book discuss various aspects of theoretical Rheology and, by examples of many studies, show how particular theory, model, or equation can be used in solving different problems. The main emphasis is on liquids, but solid materials are discussed in one full chapter as well. Methods of measurement and raw data treatment are included in one large chapter which constitutes more than one quarter of the book. Eight groups of methods are discussed giving many choices for experimentation and guidance on where and how to use them properly. The final chapter shows how to use rheological methods in different groups of products and methods of their manufacture. Usefulness of chemorheological (rheokinetical) measurements is also emphasized. This chapter continues with examples of purposeful applications in practical matters.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to present a model, based on rational mechanics of electrorheological fluids, that takes into account the complex interactions between the electromagnetic fields and the moving liquid. Several constitutive relations for the Cauchy stress tensor are discussed. The main part of the book is devoted to a mathematical investigation of a model possessing shear-dependent viscosities, proving the existence and uniqueness of weak and strong solutions for the steady and the unsteady case. The PDS systems investigated possess so-called non-standard growth conditions. Existence results for elliptic systems with non-standard growth conditions and with a nontrivial nonlinear r.h.s. and the first ever results for parabolic systems with a non-standard growth conditions are given for the first time. Written for advanced graduate students, as well as for researchers in the field, the discussion of both the modeling and the mathematics is self-contained.
