Download or read book Effects of Variable Viscosity and Variable Permeability on Fluid Flow Through Porous Media written by Sayer Obaid B. Alharbi and published by . This book was released on 2016 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, we study the effects of variable viscosity and variable permeability on single-phase fluid flow through porous structures. This is accomplished by first deriving the equations governing fluid flow through porous structures in which porosity (hence permeability) is a function of position and viscosity of the fluid is pressure-dependent. The governing equations are derived using intrinsic volume averaging, and viscous effects are accounted for through Brinkman’s viscous shear term. When the Darcy resistance, Brinkman’s viscous shear effects and Lapwood’s macroscopic inertial terms are accounted for, the governing equation is known as the Darcy-Lapwood-Brinkman equation, and it governs the flow through a mushy zone undergoing rapid freezing, and is important in slurry transport. Three exact solutions to the Darcy-Lapwood-Brinkman equation with variable permeability are obtained in this work. Solutions are obtained for a given vorticity distribution, taken as a function of the streamfunction. Classification of the flow field is provided and comparison is made with the solutions obtained when permeability is constant. Interdependence of Reynolds number and the variable permeability is emphasized. Exact solutions are also obtained for this equation when the vorticity is proportional to the streamfunction, and a derivation of the permeability function that satisfies the governing equations is provided. The problem of laminar flow through a porous medium of variable permeability, behind a two-dimensional grid is considered in this work to further shed some light of the effects of permeability variations. Expressions for the permeability profiles are derived when the model equations are linearized and permeability is calculated at the stagnation points of the flow. Conditions on the parameters involved in the exact solution are analyzed and stated and the flow is classified and compared with the case of flow through constant permeability media. This work might be of interest in the stability analysis of flow through variable permeability media. In studying the effects of pressure-dependent viscosity on fluid flow, this work provided analysis involving viscosity stratification. Coupled parallel flow of fluids with viscosity stratification through two porous layers is initiated in this work. Conditions at the interface are discussed and appropriate viscosity stratification functions are selected in such a way that viscosity is highest at the bounding walls and decreases to reach its minimum at the interface. Velocity and shear stress at the interface are computed for different permeability and driving pressure gradient. Consideration is given to two-dimensional flow of a fluid with pressure-dependent viscosity through a variable permeability porous structure. Exact solutions are obtained for a Riabouchinsky type flow using a procedure that is based on an existing methodology that is implemented in the study of Navier-Stokes flow with pressure-dependent viscosity. Viscosity is considered proportional to fluid pressure due to the importance and uniqueness of validity of this type of relation in the study of Poiseuille flow. The effects of changing the proportionality constant on the pressure distribution are discussed. Since a variable permeability introduces an additional variable in the flow equations and renders the governing equations under-determined, the current work devises a methodology to determine the permeability function through satisfaction of a condition derived from the specified streamfunction. Illustrative examples are used to demonstrate how the variable permeability is determined, and how the arising parameters are determined. Although the current work considers flow in an infinite domain and does not handle a particular engineering problem, it nevertheless initiates the study of flow of fluids with pressure-dependent viscosity through variable-permeability media and sets the stage for future work in stability analysis of this type of flow. It is expected that the current work will be of value in transition layer analysis and the determination of variable permeability functions suitable for such analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Many of the topics in inviscid fluid dynamics are not only vitally important mechanisms in everyday life but they are also readily observable without any need for instrumentation. It is therefore stimulating when the mathematics that emerges when these phenomena are modelled is novel and suggestive of alternative methodologies. This book provides senior undergraduates who are already familiar with inviscid fluid dynamics with some of the basic facts about the modelling and analysis of viscous flows. It clearly presents the salient physical ideas and the mathematical ramifications with exercises designed to be an integral part of the text. By showing the basic theoretical framework which has developed as a result of the study of viscous flows, the book should be ideal reading for students of applied mathematics who should then be able to delve further into the subject and be well placed to exploit mathematical ideas throughout the whole of applied science.

Download or read book Convective Heat Transfer written by I. Pop and published by Elsevier. This book was released on 2001-02-23 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in studying the phenomena of convective heat and mass transfer between an ambient fluid and a body which is immersed in it stems both from fundamental considerations, such as the development of better insights into the nature of the underlying physical processes which take place, and from practical considerations, such as the fact that these idealised configurations serve as a launching pad for modelling the analogous transfer processes in more realistic physical systems. Such idealised geometries also provide a test ground for checking the validity of theoretical analyses. Consequently, an immense research effort has been expended in exploring and understanding the convective heat and mass transfer processes between a fluid and submerged objects of various shapes. Among several geometries which have received considerable attention are plates, circular and elliptical cylinders, and spheres, although much information is also available for some other bodies, such as corrugated surfaces or bodies of relatively complicated shapes. The book is a unified progress report which captures the spirit of the work in progress in boundary-layer heat transfer research and also identifies potential difficulties and areas for further study. In addition, this work provides new material on convective heat and mass transfer, as well as a fresh look at basic methods in heat transfer. Extensive references are included in order to stimulate further studies of the problems considered. A state-of-the-art picture of boundary-layer heat transfer today is presented by listing and commenting also upon the most recent successful efforts and identifying the needs for further research.

Download or read book Micropolar Fluids written by Grzegorz Lukaszewicz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micropolar fluids are fluids with microstructure. They belong to a class of fluids with nonsymmetric stress tensor that we shall call polar fluids, and include, as a special case, the well-established Navier-Stokes model of classical fluids that we shall call ordinary fluids. Physically, micropolar fluids may represent fluids consisting of rigid, randomly oriented (or spherical) particles suspended in a viscous medium, where the deformation of fluid particles is ignored. The model of micropolar fluids introduced in [65] by C. A. Eringen is worth studying as a very well balanced one. First, it is a well-founded and significant generalization of the classical Navier-Stokes model, covering, both in theory and applications, many more phenomena than the classical one. Moreover, it is elegant and not too complicated, in other words, man ageable to both mathematicians who study its theory and physicists and engineers who apply it. The main aim of this book is to present the theory of micropolar fluids, in particular its mathematical theory, to a wide range of readers. The book also presents two applications of micropolar fluids, one in the theory of lubrication and the other in the theory of porous media, as well as several exact solutions of particular problems and a numerical method. We took pains to make the presentation both clear and uniform.
