Download or read book Infrared Thermography for Thermo Fluid Dynamics written by Tommaso Astarita and published by Springer Science & Business Media. This book was released on 2012-08-04 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared thermography is a measurement technique that enables to obtain non intrusive measurements of surface temperatures. One of the interesting features of this technique is its ability to measure a full two dimensional map of the surface temperature and for this reason it has been widely used as a flow visualization technique. Since the temperature measurements can be extremely accurate it is possible, by using a heat flux sensor, also to measure convective heat transfer coefficient distributions on a surface making the technique de facto quantitative. This book, starting from the basic theory of infrared thermography and heat flux sensor guides, both the experienced researcher and the young student, in the correct application of this powerful technique to various practical problems. A significant number of examples and applications are also examined in detail.
Download or read book Thermofluid Dynamics written by Michele Ciofalo and published by Springer Nature. This book was released on 2023-05-19 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers ten thermofluid dynamics problems involving the use of analytical solutions. All these problems have been encountered by the author during his research activity; some of the solutions are his own contributions, while others either are classic literature results or can be derived from them. The physical phenomena involved range from pure hydrodynamics to flow with heat or mass transfer, two-phase flow, and magnetohydrodynamics. The problems discussed are not canonical problems; they are rarely found in textbooks, and often exhibit surprising, or even paradoxical, solutions. The potential readership of the book includes students, teachers and scientists in science and engineering interested in fluid dynamics and heat/mass transfer: to them it may offer food for thought, suggestions for lectures or tutorials and ideas for further original developments.
Download or read book Fluid Mechanics written by L D Landau and published by Elsevier. This book was released on 2013-09-03 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid Mechanics, Second Edition deals with fluid mechanics, that is, the theory of the motion of liquids and gases. Topics covered range from ideal fluids and viscous fluids to turbulence, boundary layers, thermal conduction, and diffusion. Surface phenomena, sound, and shock waves are also discussed, along with gas flow, combustion, superfluids, and relativistic fluid dynamics. This book is comprised of 16 chapters and begins with an overview of the fundamental equations of fluid dynamics, including Euler's equation and Bernoulli's equation. The reader is then introduced to the equations of motion of a viscous fluid; energy dissipation in an incompressible fluid; damping of gravity waves; and the mechanism whereby turbulence occurs. The following chapters explore the laminar boundary layer; thermal conduction in fluids; dynamics of diffusion of a mixture of fluids; and the phenomena that occur near the surface separating two continuous media. The energy and momentum of sound waves; the direction of variation of quantities in a shock wave; one- and two-dimensional gas flow; and the intersection of surfaces of discontinuity are also also considered. This monograph will be of interest to theoretical physicists.
Download or read book Bubbly Flows written by Martin Sommerfeld and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 354 pages. 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.

Download or read book Engineering Thermofluids written by Mahmoud Massoud and published by Springer Science & Business Media. This book was released on 2005-09-16 with total page 1132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermofluids, while a relatively modern term, is applied to the well-established field of thermal sciences, which is comprised of various intertwined disciplines. Thus mass, momentum, and heat transfer constitute the fundamentals of th- mofluids. This book discusses thermofluids in the context of thermodynamics, single- and two-phase flow, as well as heat transfer associated with single- and two-phase flows. Traditionally, the field of thermal sciences is taught in univer- ties by requiring students to study engineering thermodynamics, fluid mechanics, and heat transfer, in that order. In graduate school, these topics are discussed at more advanced levels. In recent years, however, there have been attempts to in- grate these topics through a unified approach. This approach makes sense as thermal design of widely varied systems ranging from hair dryers to semicond- tor chips to jet engines to nuclear power plants is based on the conservation eq- tions of mass, momentum, angular momentum, energy, and the second law of thermodynamics. While integrating these topics has recently gained popularity, it is hardly a new approach. For example, Bird, Stewart, and Lightfoot in Transport Phenomena, Rohsenow and Choi in Heat, Mass, and Momentum Transfer, El- Wakil, in Nuclear Heat Transport, and Todreas and Kazimi in Nuclear Systems have pursued a similar approach. These books, however, have been designed for advanced graduate level courses. More recently, undergraduate books using an - tegral approach are appearing.
Download or read book A Text Book In Basic Thermo Fluid Dynamics written by Mohammad R. a. Shaalan and published by Mohammad Raafat Shaalan. This book was released on 2022-04-19 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is recognized that the study of mechanical engineering is built of a number of engineering sciences, some of which are of basic nature whereas some other are of applied nature. "Basic Thermodynamics" and "Basic Fluid Dynamics" are probably the two most important basic engineering sciences in the build of a Mechanical Power Engineer. In applied mechanical power engineering sciences, the principles introduced and analysed in these two basic sciences are common divisors. In other words, we may look at these two branches of basic engineering sciences as two legs on which Mechanical Power Engineering applications appear to stand. The science of "Basic Thermodynamics " is based mainly on a number of basic principles (in the form of laws) that lead to a number of equations describing and governing the behavior of several mechanical power systems. It is therefore of particular importance to introduce and analyse such equations. It is also essential to relate these principles and equations to each other and, whenever possible, to pertinent phenomena and applications. This may be achieved via worked examples that stem from from engineering practice. The science of "Basic Fluid Dynamics" is another basic engineering science of equal importance to "Basic Thermodynamics". The principles introduced and analysed by this basic science find applications in almost all applied mechanical power engineering sciences. Examples of these applied sciences are "Applied Thermodynamics", "Applied Fluid Dynamics", "Combustion Engineering"," Turbo-machinery", "Refrigeration and Air-conditioning", "Power Plants", "Gas dynamics". "Propulsion systems" ….etc. Because of the close inter-relation between the science of basic thermodynamics and the science of basic fluid dynamics, it has become a common practice to contained both sciences in one textbook under the title “Basic Thermo/fluid Dynamics” (the title of the present textbook). The present textbook on "Basic Thermo/fluid Dynamics" has been divided into distinct parts: A and B. In part A, we concentrate on "Basic Thermodynamics", attempting to present, with as much clarity as possible, the basic principles therein and giving several worked examples for the sake of clarification. In part B, we concentrate on "Basic Fluid Dynamics", applying the same philosophy as in Part A. In this part also, a special section (in chapter five) containing a rather concise manipulation of the applied science of "Compressible Fluid (Gas) Dynamics" is presented, being an important combined application of the basic principles discussed in thermodynamics and fluid dynamics. Moreover, It was felt by the authors that it is particularly important to include this section on gas dynamics, since, in spite of being applied in nature, it is regarded by many as basic more than applied. The last chapter of Part A and chapter five of Part B cover some important engineering applications of the principles given apriori. Each of these applications may be looked upon as a brief exposition of an applied engineering science carrying the title of the application under consideration. This was felt imperative to the advantage hopefully to be gained by the student. The authors are indebted to their colleague Dr. Mohammad S.H. Emeara of the Mechanical Power Engineering Department, Zagazig University, for assisting with part of the illustrations and wish to thank him for rendering this assistance in the early stages of preparation of this textbook.

Download or read book Two Fluid Model Stability Simulation and Chaos written by Martín López de Bertodano and published by Springer. This book was released on 2016-11-09 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the linear and nonlinear two-phase stability of the one-dimensional Two-Fluid Model (TFM) material waves and the numerical methods used to solve it. The TFM fluid dynamic stability is a problem that remains open since its inception more than forty years ago. The difficulty is formidable because it involves the combined challenges of two-phase topological structure and turbulence, both nonlinear phenomena. The one dimensional approach permits the separation of the former from the latter.The authors first analyze the kinematic and Kelvin-Helmholtz instabilities with the simplified one-dimensional Fixed-Flux Model (FFM). They then analyze the density wave instability with the well-known Drift-Flux Model. They demonstrate that the Fixed-Flux and Drift-Flux assumptions are two complementary TFM simplifications that address two-phase local and global linear instabilities separately. Furthermore, they demonstrate with a well-posed FFM and a DFM two cases of nonlinear two-phase behavior that are chaotic and Lyapunov stable. On the practical side, they also assess the regularization of an ill-posed one-dimensional TFM industrial code. Furthermore, the one-dimensional stability analyses are applied to obtain well-posed CFD TFMs that are either stable (RANS) or Lyapunov stable (URANS), with the focus on numerical convergence.
