Book Synopsis Micropolar Fluids by : Grzegorz Lukaszewicz
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.

Book Synopsis Heat Transfer Due to Laminar Natural Convection of Nanofluids by : De-Yi Shang
Download or read book Heat Transfer Due to Laminar Natural Convection of Nanofluids written by De-Yi Shang and published by Springer. This book was released on 2018-07-30 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a theoretical study of heat transfer due to laminar natural convection of nanofluids, using Al2O3-water nanofluid as an example. An innovative method of similarity transformation of velocity fields on laminar boundary layers is applied for the development of a mathematical governing model of natural convection with actual nanofluids, and a novel model of the nanofluid's variable thermophysical properties is derived by a mathematical analysis based on the developed model of variable physical properties of fluids combined with the model of the nanofluid's thermal conductivity and viscosity. Based on these, the physical property factors of nanofluids are produced, which leads to a simultaneous solution for deep investigations of hydrodynamics and heat transfer of nanofluid's natural convection. The book also proposes novel predictive formulae for the evaluation of heat transfer of Al2O3-water nanofluid’s natural convection. The formulae have reliable theoretical and practical value because they are developed by rigorous theoretical analysis of heat transfer combined with full consideration of the effects of the temperature-dependent physical properties of nanofluids and the nanoparticle shape factor and concentration, as well as variations of fluid boundary temperatures. The conversion factors proposed help to turn the heat transfer coefficient and rate of fluid natural convection into those of nanofluid natural convection. Furthermore, several calculation examples are provided to demonstrate the heat transfer application of the proposed predictive formulae.
Book Synopsis Kinetic Theory and Fluid Dynamics by : Yoshio Sone
Download or read book Kinetic Theory and Fluid Dynamics written by Yoshio Sone and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is intended to provide a comprehensive description of the rela tion between kinetic theory and fluid dynamics for a time-independent behavior of a gas in a general domain. A gas in a steady (or time-independent) state in a general domain is considered, and its asymptotic behavior for small Knudsen numbers is studied on the basis of kinetic theory. Fluid-dynamic-type equations and their associated boundary conditions, together with their Knudsen-layer corrections, describing the asymptotic behavior of the gas for small Knudsen numbers are presented. In addition, various interesting physical phenomena derived from the asymptotic theory are explained. The background of the asymptotic studies is explained in Chapter 1, accord ing to which the fluid-dynamic-type equations that describe the behavior of a gas in the continuum limit are to be studied carefully. Their detailed studies depending on physical situations are treated in the following chapters. What is striking is that the classical gas dynamic system is incomplete to describe the behavior of a gas in the continuum limit (or in the limit that the mean free path of the gas molecules vanishes). Thanks to the asymptotic theory, problems for a slightly rarefied gas can be treated with the same ease as the corresponding classical fluid-dynamic problems. In a rarefied gas, a temperature field is di rectly related to a gas flow, and there are various interesting phenomena which cannot be found in a gas in the continuum limit.

This book was released on 2023-03-08 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2022 in the subject Mathematics - Applied Mathematics, grade: 75.0%, Ladoke Akintola University of Technology, course: Applied Mathematics, language: English, abstract: This thesis aimed at studying the reacting system of boundary layer flow of CuO-Oil- based Nanofluid with heat generation through a vertical permeable surface. A boundary layer is formed whenever there is a relative motion between the boundary and the fluid. The details of flow within the boundary layer are very important for the understanding of many problems in aerodynamics, including the wind stall, the skin- drag on an object, heat transfers that occur in high speed flight and in naval architecture for the designs of ships and submarines. The concept of boundary layer was first introduced by Prandtl in 1904 and since then it has been applied to several fluid flowproblems. The science of fluid dynamics encompasses the movement of gases and liquids, interaction of fluid with solid and the study of forces related to these phenomena. It plays an important role in every aspect of our daily life for example from morning bath to evening coffee. It has potential applications in the field of science, engineering, manufacturing, transportation, environment, medicine, energy and others. Flows are important for the existence of natural and technical world. Properties of the fluid, forces acting on the fluid particles and boundaries of the flow domain determine the resultant flow pattern. Deformation of fluids occurs continuously under application of shear stress which makes them isotropic substances. Navier-Stokes equations are the fundamental equations of the fluid that portray the stream as either Newtonian or non-Newtonian Harlow and Amsden. There is a broad scope of heat transfer applications in numerous industrial processes involving mechanical, electrical and chemical industry. Achieving higher convective rate of heat transfer in thermal systems and processes has always been the challenges facing Scientists and Engineers. As a result, this process requires an immensity amount of vitality to manage the method of fluid heating/cooling and transport of heat. It is known that cooling is necessary for maintaining the preferred performance and steadfastness of an engine. Heat transfer fluids like water, oil, ethyl glycol and salt water collect and transport heat from the region with high temperature to the region with low temperature. In Automobiles, piston converts the heat generated as a result of the combustion of the fuel into mechanical work and drives the crankshaft in the course of the connecting rod. Continuous heating of the piston without proficient cooling can lead to elevated fuel and oil utilization, harmful exhaust emissions, reduction in engine power output or undeviating engine damage. Heat transfer fluids are expected to have high thermal conductivity, high volumetric heat capacity, and low viscosity. On the other hand, the heat carrier fluids have low thermal conductivity and affect the proper functioning of the system. In order to guarantee durability, reliability and extend lifespan of an engine, there is need for use of heat carriers’ fluid with improved heat transfer properties. The innovative conception of nanofluid was proposed as a solution to these challenges. Nanofluid, an improved heat transfer fluid, is a fluid-dispersed which contains nanoparticles of size range (1-100nm). The fluids such as oil, water and ethyl glycol are some of the fluids used in nanofluid. Materials commonly used as nanoparticles are chemically stable metals (copper, gold), metal oxides (CuO, Al O ) and Carbon in various forms (diamond, graphite, carbon nanotubes). The mixture of concentration of nanopaticles into the heat carrier fluids enhances the viscosity of nanofluids and other thermo-physical properties like thermal conductivity, specific heat capacity and density. Oil based nanofluids is used in the cooling of electronic equipment, nuclear reactors, power transformers and automobile engines. Oil in an engine cushions the bearings in opposition to the shocks of firing cylinders. It serves as lubricant to neutralize the corrosive elements during combustions and prevents the metal surfaces of an engine from rust. It also serves as coolant agent for parts of engine that are not exposed to the water-cooling system. Metal oxides are commonly used as thermal additives in Nanofluid due to their outstanding properties such as high thermal conductivity and excellent compatibility with base fluid. Al O , TiO , ZnO and CuO are the most popular metal oxides nanoparticles. Nanofluids containing metal oxides have exhibited special potentials in heat transfer applications. Among various metal oxides nanoparticles, CuO has higher thermal conductivity; it is a monoclinic crystal structure and has many attractive properties. CuO particles have spheroid shapes and most of the particles are under aggregate states. And to have an efficient Nanofluid, the particles should have spherical shape to have a higher critical dilute limit. Excessive concentration of nanoparticles in base fluid at low temperature leads to increase in the density of nanofluid, which is the compactness of nanoparticles, it results into very thick nanofluid and this leads to viscous nano-oil which provides stronger fluid film and the thicker the nanofluid film, the more resistant it will be rubbed from lubricated surfaces. Nanofluids’ viscosity is the measure of its thickness or struggle to flow. It is directly connected with how well oil based nanofluid lubricates and protects surfaces that it moves through. However, very thick nanofluid offers excessive resistance to flow at low temperatures and as a result may not flow quickly enough to those parts requiring lubrication. It is therefore crucial that for nanofluid to be effective, it must exhibit moderate concentration of nanoparticles and the right thermo-physical properties at both the highest and the lowest temperatures which are necessity for proper functional of the engine.

This book was released on 2020-08-19 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of fluid flow and heat transfer in a porous medium have been the subject of continuous interest for the past several decades because of the wide range of applications, such as geothermal systems, drying technologies, production of thermal isolators, control of pollutant spread in groundwater, insulation of buildings, solar power collectors, design of nuclear reactors, and compact heat exchangers, etc. There are several models for simulating porous media such as the Darcy model, Non-Darcy model, and non-equilibrium model. In porous media applications, such as the environmental impact of buried nuclear heat-generating waste, chemical reactors, thermal energy transport/storage systems, the cooling of electronic devices, etc., a temperature discrepancy between the solid matrix and the saturating fluid has been observed and recognized.

This book was released on 2013-04-18 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is concerned with the transport of thermal energy in flows of practical significance. The temperature distributions which result from convective heat transfer, in contrast to those associated with radiation heat transfer and conduction in solids, are related to velocity characteristics and we have included sufficient information of momentum transfer to make the book self-contained. This is readily achieved because of the close relation ship between the equations which represent conservation of momentum and energy: it is very desirable since convective heat transfer involves flows with large temperature differences, where the equations are coupled through an equation of state, as well as flows with small temperature differences where the energy equation is dependent on the momentum equation but the momentum equation is assumed independent of the energy equation. The equations which represent the conservation of scalar properties, including thermal energy, species concentration and particle number density can be identical in form and solutions obtained in terms of one dependent variable can represent those of another. Thus, although the discussion and arguments of this book are expressed in terms of heat transfer, they are relevant to problems of mass and particle transport. Care is required, however, in making use of these analogies since, for example, identical boundary conditions are not usually achieved in practice and mass transfer can involve more than one dependent variable.
