This book was released on 2013-04-17 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experts in rheology and polymer processing present up-to-date, fundamental and applied information on the rheological properties of polymers, in particular those relevant to processing, contributing to the physical understanding and the mathematical modelling of polymer processing sequences. Basic concepts of non-Newtonian fluid mechanics, micro-rheological modelling and constitutive modelling are reviewed, and rheological measurements are described. Topics with practical relevance are debated, such as linear viscoelasticity, converging and diverging flows, and the rheology of multiphase systems. Approximation methods are discussed for the computer modelling of polymer melt flow. Subsequently, polymer processing technologies are studied from both simulation and engineering perspectives. Mixing, crystallization and reactive processing aspects are also included. Audience: An integrated and complete view of polymer processing and rheology, important to institutions and individuals engaged in the characterisation, testing, compounding, modification and processing of polymeric materials. Can also support academic polymer processing engineering programs.

Download or read book Potential Flows of Viscous and Viscoelastic Liquids written by Daniel Joseph and published by Cambridge University Press. This book was released on 2007-12-17 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates how potential flows enter into the general theory of motions of viscous and viscoelastic fluids. Traditionally, the theory of potential flow is presented as a subject called 'potential flow of an inviscid fluid'; when the fluid is incompressible these fluids are, curiously, said to be 'perfect' or 'ideal'. This type of presentation is widespread; it can be found in every book on fluid mechanics, but it is flawed. It is never necessary and typically not useful to put the viscosity of fluids in potential (irrotational) flow to zero. The dimensionless description of potential flows of fluids with a nonzero viscosity depends on the Reynolds number, and the theory of potential flow of an inviscid fluid can be said to rise as the Reynolds number tends to infinity. The theory given here can be described as the theory of potential flows at finite and even small Reynolds numbers.

Download or read book Fluid Dynamics of Viscoelastic Liquids written by Daniel D. Joseph and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 772 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about two special topics in rheological fluid mechanics: the elasticity of liquids and asymptotic theories of constitutive models. The major emphasis of the book is on the mathematical and physical consequences of the elasticity of liquids; seventeen of twenty chapters are devoted to this. Constitutive models which are instantaneously elastic can lead to some hyperbolicity in the dynamics of flow, waves of vorticity into rest (known as shear waves), to shock waves of vorticity or velocity, to steady flows of transonic type or to short wave instabilities which lead to ill-posed problems. Other kinds of models, with small Newtonian viscosities, give rise to perturbed instantaneous elasticity, associated with smoothing of discontinuities as in gas dynamics. There is no doubt that liquids will respond like elastic solids to impulses which are very rapid compared to the time it takes for the molecular order associated with short range forces in the liquid, to relax. After this, all liquids look viscous with signals propagating by diffusion rather than by waves. For small molecules this time of relaxation is estimated as lQ-13 to 10-10 seconds depending on the fluids. Waves associated with such liquids move with speeds of 1 QS cm/s, or even faster. For engineering applications the instantaneous elasticity of these fluids is of little interest; the practical dynamics is governed by diffusion, ·say, by the Navier-Stokes equations. On the other hand, there are other liquids which are known to have much longer times of relaxation.

Available in PDF, EPUB and Kindle. Book excerpt: More than possibly any other scientific discipline, rheology is easily visualized and the relevant literature contains many excellent photographs of unusual and often bizarre phenomena. The present book brings together these photographs for the first time. They are supported by a full explanatory text. Rheological Phenomena in Focus will be an indispensable support manual to all those who teach rheology or have to convince colleagues of the practical relevance of the subject within an industrial setting. For those who teach fluid mechanics, the book clearly illustrates the difference between inelastic fluids and viscoelastic fluids in a number of important flow fields. For example, the influence of the configuration of molecules in an entry flow, the influence of rounding corners, the reluctance of elastic liquids to turn corners, and the sensitivity of elastic fluids to asymmetries in the flow are clearly illustrated. In addition many flow instabilities, where fluid elasticity is clearly the dominant variable, are shown.

Download or read book Heat Transfer to Non-Newtonian Fluids written by Aroon Shenoy and published by John Wiley & Sons. This book was released on 2018-03-12 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been written with the idea of providing the fundamentals for those who are interested in the field of heat transfer to non-Newtonian fluids. It is well recognized that non-Newtonian fluids are encountered in a number of transport processes and estimation of the heat transfer characteristics in the presence of these fluids requires analysis of equations that are far more complex than those encountered for Newtonian fluids. A deliberate effort has been made to demonstrate the methods of simplification of the complex equations and to put forth analytical expressions for the various heat transfer situations in as vivid a manner as possible. The book covers a broad range of topics from forced, natural and mixed convection without and with porous media. Laminar as well as turbulent flow heat transfer to non-Newtonian fluids have been treated and the criterion for transition from laminar to turbulent flow for natural convection has been established. The heat transfer characteristics of non-Newtonian fluids from inelastic power-law fluids to viscoelastic second-order fluids and mildly elastic drag reducing fluids are covered. This book can serve the needs of undergraduates, graduates and industry personnel from the fields of chemical engineering, material science and engineering, mechanical engineering and polymer engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Escoamentos de fluidos viscoplásticos através de expansões e contrações são encontrados em diversos processos industriais. Neste trabalho é feita a simulação numérica do escoamento de um fluido viscoplástico através de umaexpansão abrupta axisimétrica seguida de uma contração. Resultados experimentais mostram que em certas condições para este tipo de escoamento pode surgir uma região estacionária do fluido, causado uma fratura do materialentre esta região e a região de escoamento. Um dos objetivos deste trabalho é verificar se o modelo constitutivo usado na simulação numérica pode prever estetipo de comportamento. Outro objetivo é investigar os efeitos dos parâmetros geométricos e reológicos nos padrões de escoamento. A solução numérica das equações de conservação de massa e quantidade de movimento é obtida usando o método de volumes finitos. Para modelar o comportamento não Newtoniano do fluido, é utilizada a equação constitutiva de Fluido Newtoniano Generalizado. Duas diferentes equações são utilizadas para a função viscosidade: o modelo de Carreau-Yasuda e o modelo de Herschel-Bulkley. A solução numérica fornece os campos de velocidade, viscosidade e pressão. Observa-se que existe uma transição no padrão de escoamento quando o comprimento do duto central (que é o de maior diâmetro) aumenta. Para baixos valores da razão entre o comprimento e o diâmetro do duto central, o material viscoplástico parece fraturar perto da região central do escoamento. Para valores maiores desta mesma razão, o padrão de escoamento dos materiais viscoplásticos tem o mesmo comportamento qualitativoao de um fluido Newtoniano, não sendo observado nenhuma fratura.
