The last thirty years have seen great leaps forward in the subject of magnetoconvection. Computational techniques can now explain exotic nonlinear behaviour, transition to chaos and the formation of structures that can be observed on the surface of the Sun. Here, two leading experts present the current state of knowledge of the subject. They provide a mathematical and numerical treatment of the interactions between electrically conducting fluids and magnetic fields that lead to the complex structures and rich behaviour observed on the Sun and other stars, as well as in the interiors of planets like the Earth. The authors' combined analytical and computational approach provides a model for the study of a wide range of related problems. The discussion includes bifurcation theory, chaotic behaviour, pattern formation in two and three dimensions, and applications to geomagnetism and to the properties of sunspots and other features at the solar surface.

This concise text provides an essential treatment of thermodynamics and a discussion of the basic principles built on an intuitive description of the microscopic behavior of matter. Aimed at a range of courses in mechanical and aerospace engineering, the presentation explains the foundations valid at the macroscopic level in relation to what happens at the microscopic level, relying on intuitive and visual explanations which are presented with engaging cases. With ad hoc, real-word examples related also to current and future renewable energy conversion technologies and two well-known programs used for thermodynamic calculations, FluidProp and StanJan, this text provides students with a rich and engaging learning experience.

Intended for advanced undergraduate and graduate students, the first four chapters of this book are devoted to the introduction of the finite element concept. The focus then covers two essential areas - heat transfer and fluid mechanics: topics with different finite element formulations. Heat transfer applications begin with the classical one-dimensional thin-rod problem, followed by the two-dimensional heat transfer problem including a variety of boundary conditions. Finally, a complicated-geometry three-dimensional problem, involving a cooled radial turbine rotor, is presented, with the cooling passages treated as 'heat sinks' in the finite element analysis. For fluid mechanics, the concept of 'nodeless' degrees of freedom is introduced, with real-life fluid-flow applications. The time-dependent finite-element analysis topic is addressed through the problem of unsteady stator/rotor flow interaction within a turbomachinery stage. Finally, the concept of 'virtually-deformable finite elements', as it relates to the problem of fluid-induced vibration, is explained in detail with many practical applications.

Flussigkeiten und gasfoermige Stoffe koennen sich in der Natur auf l verschiedene Art bewegen . Betrachtet man z. B. die Stroemung uber ein Wehr, so hat man den Eindruck, als ob das Wasser an der UEberfall- steIle ein Glasgebilde ist. Das Wasser scheint in einzelnen Faden zu stroemen, die einander nicht durchdringen und ihre Bahn beibehalten. Im Unterlaufe nach dem Wehr dagegen befindet sich das Wasser in starker Wirbelung, wobei es nicht mehr moeglich ist, einzelne Wasser- faden zu verfolgen. Jetzt lagert sich eine mehr oder weniger energische Querbewegung uber die in Richtung des Laufes gehende Hauptstroemung. Diese beiden Stroemungsarten: Fadenstroemung und Wirbelstroemung gibt es auch in geschlossenen Rohrleitungen. Die Fadenstroemung wird allgemein Schichten- oder Laminarstroemung (lamina = Schichte) ge- nannt. Eine wirbelige Bewegung heisst allgemein turbulent (= sturmisch, ungestum). Jede in der Natur beobachtbare Flussigkeits- oder Gasbewegung ist entweder eine turbulente oder eine Laminarstroemung. Diese ist an kleine StI: oemungsgeschwindigkeiten oder genauer Reynolds-Zahlen ge- bunden, jene tritt bei grossen Geschwindigkeiten oder Reynolds-Zahlen auf. Bei Laminarstroemung bewegen sich die einzelnen Teilchen standig in gleichem Abstand zur Rohrachse, im Falle von Turbulenz fuhren sie neben dieser Hauptbewegung noch regellose rasch hin- und her- gehende immer neu angefachte Seitenbewegungen aus, die die Eigen- schaft besitzen, dass ihr Mittelwert schon nach sehr kurzer Zeit ver- schwindet. Die technische Praxis arbeitet fast immer mit grossen Foerdergeschwindigkeiten und daher mit turbulenten Rohrstroemungen.

Der Begleiter durch das klassische "Dickbrettbohrerfach" des Ingenieurstudiums. Thema des Buches sind die Grundlagen der Thermodynamik, wie sie im ingenieurwissenschaftlichen Grundstudium behandelt werden. Die Thermodynamik, neben Mechanik und Mathematik eine der wichtigsten Grundlagendisziplinen in den Ingenieurwissenschaften, verkoerpert den "warmen" Maschinenbau, wo es dampft, blubbert und zischt. In diesem Buch wird das gefurchtete "Durchfallfach Thermo" in unkonventioneller, alternativer und humorvoller Weise mittels Cartoons und Beschreibungen alltaglicher Beobachtungen behandelt. Trotz der lockeren Darstellungsweise bleibt auch in diesem Buch die Korrektheit des Inhalts nicht auf der Strecke.

Als der Herausgeber dieser Buchreihe iiber die Verbrennungskraftmaschine, Herr Professor Dr. Hans List, die Bandfolge im Jahre 1938 entwarf, war folgerichtig unter den ersten Banden mit den grundlegenden Themen des Motorenbaus auch der hier jetzt vor- gelegte Band 3 iiber den Warmeiibergang in der Verbrennungskraftmaschine eingeplant. Die bis zu jenem Zeitpunkt erzielten und verbreiteten allgemeinen Kenntnisse iiber den Warmeiibergang geniigten nicht fiir die Vorgange im Verbrennungsmotor. Beim naheren Zusehen zeigte sich, daB nur NuBelt im Jahre 1923 und Eichelberg im Jahre 1937 weg- weisende Arbeiten auf diesem Sondergebiet veroffentlicht hatten. Zu jener Zeit wiirde sich aus heutiger Sicht fUr die Buchreihe nur ein schmaler Band ergeben haben, weil die weiteren und notwendigen Erkenntnisse in Verbindung mit der allgemeinen Entwicklung des Motors erst in den Jahren ab 1950 im 1n- und Ausland gewonnen wurden. Der erstgenannte der Verfasser hat bei seinen friiheren Berechnungen urn das Jahr 1932 iiber die Hochaufladung die sparlichen Erkenntnisse iiber den Warmeiibergang in del' Verbrennungskraftmaschine zu spiiren bekommen und daher durch eigene Arbeiten ver- sucht, klarend zu wirken. Als vor mehreren Jahren Prof. List anfragte, ob er - Pflau- bereit sei, den Band 3 zu verfassen, konnte zugestimmt werden. Da bekannt war, daB damals noch keine zusammenfassende Darstellung dieses Sondergebietes vorlag und mog- lichst viele der verstreuten Einzeldarstellungen zu erfassen und zu verarbeiten waren, konnte leicht dem Wunsche des Verlags nach einem zweiten und jiingeren Verfasser ent- sprochen werden. Del' erstgenannte Verfasser fand ihn in seinem langjahrigen friiheren Mitarbeiter auf diesem Gebiet.

Fur die Realisierung von energietechnischen Prozessen ist der Zweite Hauptsatz der Thermodynamik entscheidend. Er macht Aussagen uber die Wertigkeit von Energie bzw. uber die Energieentwertung in energietechnischen Prozessen. Je mehr man darauf angewiesen ist, Energie effektiv zu nutzen, umso mehr mussen solche UEberlegungen in den Entwurf, die Planung und die Optimierung energietechnischer Anlagen einbezogen werden. Genau hier setzt das vorliegende Fachbuch an, das anhand von vielen Beispielen den physikalischen Hintergrund erklart, den Ursachen von Verlusten auf den Grund geht und Moeglichkeiten zur Bewertung und zur Verbesserung von Prozessen aufzeigt.

This is a concise introduction to a subject studied by nearly every undergraduate engineering student. It covers the first and second laws of thermodynamics and their consequences for engineers, assuming no prior knowledge. Each topic is attractively presented with worked examples, and the book includes a selection of problems and answers. It will be accessible even to those students with a very weak background in physics or mathematics.

Presenting the key principles of thermodynamics from a microscopic point of view, this book provides engineers with the knowledge they need to apply thermodynamics and solve engineering challenges at the molecular level. It clearly explains the concepts of entropy and free energy, emphasizing key ideas used in equilibrium applications, whilst stochastic processes, such as stochastic reaction kinetics, are also covered. It provides a classical microscopic interpretation of thermodynamic properties, which is key for engineers, rather than focusing on more esoteric concepts of statistical mechanics and quantum mechanics. Coverage of molecular dynamics and Monte Carlo simulations as natural extensions of the theoretical treatment of statistical thermodynamics is also included, teaching readers how to use computer simulations and thus enabling them to understand and engineer the microcosm. Featuring many worked examples and over 100 end-of-chapter exercises, it is ideal for use in the classroom as well as for self-study.

This 2007 book presents a developed general conceptual and basic quantitative analysis as well as the theory of mechanical efficiency of heat engines that a level of ideality and generality compatible with the treatment given to thermal efficiency in classical thermodynamics. This yields broad bearing results concerning the overall cyclic conversion of heat into usable mechanical energy. The work reveals intrinsic limits on the overall performance of reciprocating heat engines. The theory describes the general effects of parameters such as compression ratio and external or buffer pressure on engine output. It also provides rational explanations of certain operational characteristics such as how engines generally behave when supercharged or pressurized. The results also identify optimum geometric configurations for engines operating in various regimes from isothermal to adiabatic and are extended to cover multi-workspace engines and heat pumps. Limited heat transfer due to finite-time effects have also been incorporated into the work.

This book is a unique, multidisciplinary, effort to apply rigorous thermodynamics fundamentals, a disciplined scholarly approach, to problems of sustainability, energy, and resource uses. Applying thermodynamic thinking to problems of sustainable behavior is a significant advantage in bringing order to ill defined questions with a great variety of proposed solutions, some of which are more destructive than the original problem. The articles are pitched at a level accessible to advanced undergraduates and graduate students in courses on sustainability, sustainable engineering, industrial ecology, sustainable manufacturing, and green engineering. The timeliness of the topic, and the urgent need for solutions make this book attractive to general readers and specialist researchers as well. Top international figures from many disciplines, including engineers, ecologists, economists, physicists, chemists, policy experts and industrial ecologists among others make up the impressive list of contributors.

This 2006 textbook discusses the fundamentals and applications of statistical thermodynamics for beginning graduate students in the physical and engineering sciences. Building on the prototypical Maxwell-Boltzmann method and maintaining a step-by-step development of the subject, this book assumes the reader has no previous exposure to statistics, quantum mechanics or spectroscopy. The book begins with the essentials of statistical thermodynamics, pauses to recover needed knowledge from quantum mechanics and spectroscopy, and then moves on to applications involving ideal gases, the solid state and radiation. A full introduction to kinetic theory is provided, including its applications to transport phenomena and chemical kinetics. A highlight of the textbook is its discussion of modern applications, such as laser-based diagnostics. The book concludes with a thorough presentation of the ensemble method, featuring its use for real gases. Numerous examples and prompted homework problems enrich the text.

Originally published in 1999, this book takes a probing and specialist look at the many important advances which occurred in steam power in the fifteen years leading up to its publication. Large power plants as well as small-capacity boilers became more efficient and reliable, and their design and operation were enhanced by the application of modern computational techniques. This book provides a comprehensive review of such developments in steam power engineering. It discusses thermohydraulic principles and processes, with an emphasis on practical problems of steam power plant design and operation. Among topics covered are historical analysis, cycle design, thermal and hydraulic design of heating surfaces, pollutant control, and flow instability, from which are deduced strategies for further development. Originally intended for both students and engineers, the book treats realistic problems and offers a wealth of valuable insight into the design of large and small steam power plants.

This work presents an intergrated approach to thermodynamics and heat transfer suitable for undergraduates on a mumber of courses.

In addition there are many numerical examples throughout the text and at the end of each chapter.

This inter-disciplinary guide to the thermodynamics of living organisms has been thoroughly revised and updated to provide a uniquely integrated overview of the subject. Retaining its highly readable style, it will serve as an introduction to the study of energy transformation in the life sciences and particularly as an accessible means for biology, biochemistry and bioengineering undergraduate students to acquaint themselves with the physical dimension of their subject. The emphasis throughout the text is on understanding basic concepts and developing problem-solving skills. The mathematical difficulty increases gradually by chapter, but no calculus is required. Topics covered include energy and its transformation, the First Law of Thermodynamics, Gibbs free energy, statistical thermodynamics, binding equilibria and reaction kinetics. Each chapter comprises numerous illustrative examples taken from different areas of biochemistry, as well as a broad range of exercises and references for further study.

Computational tools allow material scientists to model and analyze increasingly complicated systems to appreciate material behavior. Accurate use and interpretation however, requires a strong understanding of the thermodynamic principles that underpin phase equilibrium, transformation and state. This fully revised and updated edition covers the fundamentals of thermodynamics, with a view to modern computer applications. The theoretical basis of chemical equilibria and chemical changes is covered with an emphasis on the properties of phase diagrams. Starting with the basic principles, discussion moves to systems involving multiple phases. New chapters cover irreversible thermodynamics, extremum principles, and the thermodynamics of surfaces and interfaces. Theoretical descriptions of equilibrium conditions, the state of systems at equilibrium and the changes as equilibrium is reached, are all demonstrated graphically. With illustrative examples - many computer calculated - and worked examples, this textbook is an valuable resource for advanced undergraduates and graduate students in materials science and engineering.

Phase diagrams are used in materials research and engineering to understand the interrelationship between composition, microstructure and process conditions. In complex systems, computational methods such as CALPHAD are employed to model thermodynamic properties for each phase and simulate multicomponent phase behavior. Written by recognized experts in the field, this is the first introductory guide to the CALPHAD method, providing a theoretical and practical approach. Building on core thermodynamic principles, this book applies crystallography, first principles methods and experimental data to computational phase behavior modeling using the CALPHAD method. With a chapter dedicated to creating thermodynamic databases, the reader will be confident in assessing, optimizing and validating complex thermodynamic systems alongside database construction and manipulation. Several case studies put the methods into a practical context, making this suitable for use on advanced materials design and engineering courses and an invaluable reference to those using thermodynamic data in their research or simulations.

Natural Convective Heat Transfer from Short Inclined Cylindersexamines a heat transfersituation of significant, practical importance not adequately dealt with in existing textbooks or in any widely available review papers. Specifically, the book introduces the reader to recent studies of natural convection from short cylinders mounted on a flat insulated basewhere there isan "exposed" upper surface. Theauthor considers the effects of the cylinder cross-sectional shape, the cylinder inclination angle, and the length-to-cross sectional size of the cylinder. Both numerical and experimental studies are discussed and correlation equations based on the results of these studies are reviewed. This book is ideal for professionals involved with thermal management and related systems, researchers, and graduate students in the field of natural convective heat transfer, instructors in graduate level courses in convective heat transfer.
