Available in PDF, EPUB and Kindle. Book excerpt: Numerical Simulation of Non-Newtonian Flow focuses on the numerical simulation of non-Newtonian flow using finite difference and finite element techniques. Topics range from the basic equations governing non-Newtonian fluid mechanics to flow classification and finite element calculation of flow (generalized Newtonian flow and viscoelastic flow). An overview of finite difference and finite element methods is also presented. Comprised of 11 chapters, this volume begins with an introduction to non-Newtonian mechanics, paying particular attention to the rheometrical properties of non-Newtonian fluids as well as non-Newtonian flow in complex geometries. The role of non-Newtonian fluid mechanics is also considered. The discussion then turns to the basic equations governing non-Newtonian fluid mechanics, including Navier Stokes equations and rheological equations of state. The next chapter describes a flow classification in which the various flow problems are grouped under five main headings: flows dominated by shear viscosity, slow flows (slightly elastic liquids), small deformation flows, nearly-viscometric flows, and long-range memory effects in complex flows. The remainder of the book is devoted to numerical analysis of non-Newtonian fluids using finite difference and finite element techniques. This monograph will be of interest to students and practitioners of physics and mathematics.

Available in PDF, EPUB and Kindle. Book excerpt: Non-Newtonian flows and their numerical simulations have generated an abundant literature, as well as many publications and references to which can be found in this volume's articles. This abundance of publications can be explained by the fact that non-Newtonian fluids occur in many real life situations: the food industry, oil & gas industry, chemical, civil and mechanical engineering, the bio-Sciences, to name just a few. Mathematical and numerical analysis of non-Newtonian fluid flow models provide challenging problems to partial differential equations specialists and applied computational mathematicians alike. This volume offers investigations. Results and conclusions that will no doubt be useful to engineers and computational and applied mathematicians who are focused on various aspects of non-Newtonian Fluid Mechanics. - New review of well-known computational methods for the simulation viscoelastic and viscoplastic types - Discusses new numerical methods that have proven to be more efficient and more accurate than traditional methods - Articles that discuss the numerical simulation of particulate flow for viscoelastic fluids

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid mixing represents an important component of the field of fluid dynamics, what makes the understanding of this subject so meaningful from both the fundamental and applied (e.g. industrial processes) point of view. In miniaturised geometries, under typical conditions, mixing is a slow, difficult and inefficient process due to the naturally laminar character of these flows, which forces the homogenisation of different fluid elements to occur via molecular diffusion instead of faster-acting advective transport. However, recent experimental studies on low-Reynolds-number viscoelastic flows have shown that efficient mixing can be triggered in several geometrical configurations (including micro-scale devices), by the phenomenon of elastic turbulence. The first part of this thesis is devoted to the understanding and investigation of numerical challenges present in the domain of non-Newtonian fluid dynamics, focusing in particular on the high-Weissenberg number problem. The latter manifests as a breakdown of the numerical scheme when the polymeric extra-stress evolution equations are implemented in a direct way, which poses severe limits to the possibility to accurately simulate elastic turbulent flows. We provide numerical evidence of the beneficial effect (in terms of increased stability) of the square-root decomposition of the extra-stress in a finite-volume-based implementation of the governing equations in a two-dimensional channel. The second part of the thesis reports about the emergence and characterisation of purely-elastic instabilities in numerical simulations of zero-Reynolds-number Oldroyd-B fluids in a two-dimensional cross-slot geometry. By means of extensive numerical work, we provide a detailed characterisation of the purely-elastic instabilities arising in the system for wide ranges of both the fluid elasticity and the polymer concentration. For concentrated solutions and large enough Weissenberg numbers, our simulations indicate the emergence of disordered flow pointing to elastic turbulence. We analyse the transition to irregular dynamics and characterise the statistical properties of such highly elastic flows, discussing the similarities and differences with experimental results from the literature.

Available in PDF, EPUB and Kindle. Book excerpt: The book summarises the outcom of a priority research programme: 'Analysis, Modelling and Computation of Multiphase Flows'. The results of 24 individual research projects are presented. The main objective of the research programme was to provide a better understanding of the physical basis for multiphase gas-liquid flows as they are found in numerous chemical and biochemical reactors. The research comprises steady and unsteady multiphase flows in three frequently found reactor configurations, namely bubble columns without interiors, airlift loop reactors, and aerated stirred vessels. For this purpose new and improved measurement techniques were developed. From the resulting knowledge and data, new and refined models for describing the underlying physical processes were developed, which were used for the establishment and improvement of analytic as well as numerical methods for predicting multiphase reactors. Thereby, the development, lay-out and scale-up of such processes should be possible on a more reliable basis.
