Thermo-Hydrodynamic Design of Fluidized Bed Combustors
by Stephen M. Folga Walter F. Podolski Jacques X. Bouillard Robert W. LyczkowskiThermo-Hydrodynamic Design of Fluidized Bed Combustors: Estimating Metal Wastage is a unique volume that finds that the most sensitive parameters affecting metal wastage are superficial fluidizing velocity, particle diameter, and particle sphericity. Gross consistencies between disparate data sources using different techniques were found when the erosion rates are compared on the same basis using the concept of renormalization. The simplified mechanistic models and correlations, when validated, can be used to renormalize any experimental data so they can be compared on a consistent basis using a master equation.
Thermo-Magnetic Systems for Space Nuclear Reactors
by Carlos O. MaidanaIntroduces the reader to engineering magnetohydrodynamics applications and presents a comprehensive guide of how to approach different problems found in this multidisciplinary field. An introduction to engineering magnetohydrodynamics, this brief focuses heavily on the design of thermo-magnetic systems for liquid metals, with emphasis on the design of electromagnetic annular linear induction pumps for space nuclear reactors. Alloy systems that are liquid at room temperature have a high degree of thermal conductivity far superior to ordinary non-metallic liquids. This results in their use for specific heat conducting and dissipation applications. For example, liquid metal-cooled reactors are typically very compact and can be used in space propulsion systems and in fission reactors for planetary exploration. Computer aided engineering (CAE), computational physics and mathematical methods are introduced, as well as manufacturing and testing procedures. An overview on space nuclear systems is also included. This brief is an invaluable tool for design engineers and applied physicists as well as to graduate students in nuclear and mechanical engineering or in applied physics.

Thermoacoustic Instability: A Complex Systems Perspective (Springer Series in Synergetics)
by R. I. Sujith Samadhan A. PawarThis book systematically presents the consolidated findings of the phenomenon of self-organization observed during the onset of thermoacoustic instability using approaches from dynamical systems and complex systems theory. Over the last decade, several complex dynamical states beyond limit cycle oscillations such as quasiperiodicity, frequency-locking, period-n, chaos, strange non-chaos, and intermittency have been discovered in thermoacoustic systems operated in laminar and turbulent flow regimes. During the onset of thermoacoustic instability in turbulent systems, an ordered acoustic field and large coherent vortices emerge from the background of turbulent combustion. This emergence of order from disorder in both temporal and spatiotemporal dynamics is explored in the contexts of synchronization, pattern formation, collective interaction, multifractality, and complex networks. For the past six decades, the spontaneous emergence of large amplitude, self-sustained, tonal oscillations in confined combustion systems, characterized as thermoacoustic instability, has remained one of the most challenging areas of research. The presence of such instabilities continues to hinder the development and deployment of high-performance combustion systems used in power generation and propulsion applications. Even with the advent of sophisticated measurement techniques to aid experimental investigations and vast improvements in computational power necessary to capture flow physics in high fidelity simulations, conventional reductionist approaches have not succeeded in explaining the plethora of dynamical behaviors and the associated complexities that arise in practical combustion systems. As a result, models and theories based on such approaches are limited in their application to mitigate or evade thermoacoustic instabilities, which continue to be among the biggest concerns for engine manufacturers today. This book helps to overcome these limitations by providing appropriate methodologies to deal with nonlinear thermoacoustic oscillations, and by developing control strategies that can mitigate and forewarn thermoacoustic instabilities. The book is also beneficial to scientists and engineers studying the occurrence of several other instabilities, such as flow-induced vibrations, compressor surge, aeroacoustics and aeroelastic instabilities in diverse fluid-mechanical environments, to graduate students who intend to apply dynamical systems and complex systems approach to their areas of research, and to physicists who look for experimental applications of their theoretical findings on nonlinear and complex systems.

Thermodynamic and Thermophysical Properties of Saline Water: Models, Correlations and Data for Desalination and Relevant Applications (Springer Water)
by Naef A. Qasem Muhammad M. Generous Bilal A. Qureshi Syed M. ZubairThis book accommodates the existing correlations, data, and methods for thermodynamic and thermophysical properties of saline water, including multiple components at a wide range of salinity (reaching around 200 g/kg), temperature, and pressure. The correlations of each property are plotted against existing experimental data to judge the comparative accuracy of each within a given specific range of salinity, temperature, and pressure. An assessment to recommend some correlations is also conducted. New correlations for some properties are also proposed. This book helps to provide the saline water properties as needed for engineers, designers, and research for different areas, including desalination and water treatment.All the analytical analysis, thermodynamic analysis, and design models of the desalination technologies depend on saline water properties. As scientists and researchers working on different desalination technologies, the authors found it difficult to find all saline water properties in one source, including multicomponent and binary salty solutions, under different conditions (salinity, temperature, and pressure). Therefore, the authors introduce this book to fill the gap in the open literature. This book compiles the thermodynamic and thermophysical properties of saline water, involving thermodynamic approaches, multicomponent models, and simple correlations and data, comparison between the correlations of properties in figures, recommendation of the most accurate correlations and methods, and the used codes to estimate these correlations and methods. It is expected that this book to be a principal source for all interests in desalination and water treatment subjects.

Thermodynamics
by Gregory Nellis Sanford KleinThis book differs from other thermodynamics texts in its objective which is to provide engineers with the concepts, tools, and experience needed to solve practical real-world energy problems. The presentation integrates computer tools (e.g., EES) with thermodynamic concepts to allow engineering students and practising engineers to solve problems they would otherwise not be able to solve. The use of examples, solved and explained in detail, and supported with property diagrams that are drawn to scale, is ubiquitous in this textbook. The examples are not trivial, drill problems, but rather complex and timely real world problems that are of interest by themselves. As with the presentation, the solutions to these examples are complete and do not skip steps. Similarly the book includes numerous end of chapter problems, both typeset and online. Most of these problems are more detailed than those found in other thermodynamics textbooks. The supplements include complete solutions to all exercises, software downloads, and additional content on selected topics. These are available at the book web site www.cambridge.org/KleinandNellis.
