This book, which is published in two volumes, studies heat transfer problems by modern numerical methods. Basic mathematical models of heat transfer are considered. The main approaches to the analysis of the models by traditional means of applied mathematics are described. Numerical methods for the approximate solution of steady and unsteady-state heat conduction problems are discussed. Investigation of difference schemes is based on the general stability theory. Much emphasis is put on problems in which phase transitions are involved and on heat and mass transfer problems. Problems of controlling and optimizing heat processes are discussed in detail. These processes are described by partial differential equations, and the main approaches to numerical solution of the optimal control problems involved here are discussed. Aspects of numerical solution of inverse heat exchange problems are considered. Much attention is paid to the most important applied problems of identifying coefficients and boundary conditions for a heat transfer equation. This first volume considers the mathematical models of heat transfer, classic analytical solution methods for heat conduction problems, numerical methods for steady-state and transient heat conduction problems, and phase change problems. The second volume presents solution techniques for complicated heat transfer problems (radiation, convection, thermoelasticity, thermal process control and inverse problems) as well as some examples of solving particular heat transfer problems.

Foundations of Electroheat unifies an extremely diverse area of electricity utilisation in a coherent and concise reference. From laser welding to plasma furnaces for waste treatment and induction heating for forging to radio frequency drying textiles, the various topics that comprise electroheat are presented as a whole. The unified approach concentrates on three major themes:

• Electromagnetic heating, embracing direct resistance, induction heating of metals and radio frequency and microwave heating of dielectrics
• The ionised state, dealing with laser processing, plasma torches and furnaces, glow discharges for nitriding and arc furnaces for melting scrap
• Heat and mass transfer

Thermal systems are essential features in power, chemical processing, air conditioning, and other industries where heat and power are used. As the cost and complexity of designing thermal systems have increased, the need to understand and improve the design process has also grown. This book describes recent progress in the design of thermal systems. The book begins with a brief history and outline of developments in thermal system design. Chapters then discuss computer design tools for the power and chemical industries, predicting physical properties with computational tools, the use of 'pinch analysis' to improve thermal efficiency, applications of the exergy concept, the emerging concept of thermoeconomics, and the potential for artificial intelligence and expert systems in the design of thermal systems. With chapters written by internationally recognised authorities, the book offers a state-of-the-art review for both researchers and practitioners in mechanical, aerospace, chemical, and power engineering.

Combustion is very much an interdisciplinary topic, drawing together elements of chemistry, fluid mechanics and heat transfer. It is an ingredient in many undergraduate degree programmes, ranging from a pivotal role in fuel science through to a component part of courses in chemical, process and building services engineering. For many students in those disciplines where combustion in heating plant is an important part of their studies, there are often problems in coming to grips with the basic principles underlying the combustion of hydrocarbon fuels. In particular, the concepts of chemical and related thermodynamic changes can prove difficult to assimilate. The scientific literature dealing with combustion tends to be rather polarised, with a wealth of literature aimed at the specialist reader, but at a basic level the fundamentals of this important process are often treated rather tersely in textbooks on thermodynamics. The objective of this book is to provide an introduction to the basic principles of the combustion of hydrocarbon fuels in heating plant for buildings and industrial processes. In those chapters where practice in problem solving can make a positive contribution to understanding, some numerical problems have been included. Acknowledging the ever-widening use of computers in technical education, a number of algorithms which can be easily coded up for solving numerical problems have been incorporated in the text. These can prove particularly useful in, for example, the calculation of certain fluid properties, either for use in hand calculation or for incorporation into larger programs.

This text explains the basic fluid mechanics and thermodynamics underlying the design of pumps, fans, compressors and turbines in an uncomplicated way, with many examples and worked exercises. By treating the machines as either centrifugal, centripetal or axial flow devices, it explains the basic principles of each and clarifies their similarities and differences. The book covers problems such as cavitation, refers to computer-based exercises wherever possible and includes information on the current advances in analysis and performance control.

As the title implies, this book provides an introduction to thermodynamics for students on degree and HND courses in engineering. These courses are placing increased emphasis on business, design, management, and manufacture. As a consequence, the direct class-time for thermodynamics is being reduced and students are encouraged to self learn. This book has been written with this in mind. The text is brief and to the point, with a minimum of mathematical content. Each chapter defines a list of aims and concludes with a short summary. The summary provides an overview of the key words, phrases and equations introduced within the chapter. It is recognized that students see thermodynamics as a problem-solving activity and this is reflected by the emphasis on the modelling of situations. As a guide to problem solving, worked examples are included throughout the book. In addition, students are encouraged to work through the problems at the end of each chapter, for which outline solutions are provided. There is a certain timelessness about thermodynamics because the funda mentals do not change. However, there is currently some debate over which sign convention should apply to work entering, or leaving, a thermodynamic system. I have retained the traditional convention of work out of a system being positive. This fits in with the concept of a heat engine as a device that takes in heat and, as a result, produces positive work."

Twentyfour years have gone by since the publication of K. Lohner and H. Muller's comprehen sive work "Gemischbildung und Verbrennung im Ottomotor" in 1967 1.1]' Naturally, the field of mixture formation and combustion in the spark-ignition engine has wit nessed great technological advances and many new findings in the intervening years, so that the time seemed ripe for presenting a summary of recent research and developments. There fore, I gladly took up the suggestion of the editors of this series of books, Professor Dr. H. List and Professor Dr. A. Pischinger, to write a book summarizing the present state of the art. A center of activity of the Institute of Internal-Combustion Engines and Automotive Engineering at the Vienna Technical University, which I am heading, is the field of mixture formation -there fore, many new results that have been achieved in this area in collaboration with the respective industry have been included in this volume. The basic principles of combustion are discussed only to that extent which seemect necessary for an understanding of the effects of mixture formation. The focal point of this volume is the mixture formation in spark-ignition engines, covering both the theory and actual design of the mixture formation units and appropriate intake manifolds. Also, the related measurement technology is explained in this work."

The main concern of this book is the application of infinite moment theory to the problem of controllability of one-di- mensional vibrating systems (like strings and beams) and heating processes. Distributed as well as boundary control is considered. In the case of vibrating systems trigonometric moment pro- blems are to be investigated which is done on the basis of an abstract moment theory in Hilbert spaces. Equivalently, alsothe theory of linear operator equations on Hilbert spa- ces ( partly with unbounded operators) is applied to the problem of controllability and time-minimal controllability. In the case of heating processes exponential moment problems are to be dealt with which is done on the basis of an ab- stract moment theory in Banach spaces. Time-minimal control- lability is also treated with the aid of the theory of line- aroperator equations on Banach spaces. Some advanced knowledge in functional analyis and on partial differential equations is preassumed for a fluent reader of the book, but parts of it are also readable with basic ma- thematical knowledge (for instance, the finite-dimensional part of the introduction).

The German R + D program "Solares Testzentrum Almeria" (SOTA) provided the scientific basis for the realization of advanced solar technologies including facility modifications, component tests and new lines of development. One of the working packages, WP 300, addressed the "Scientific Support" by the performance of preparatory studies, exploratory laboratory activities and qualified expertise. Universities, Research Institutes and Company R + D Entities in Germany were enabled to treat the following aspects: * Meteorological, system and cost investigations, * Development of important components as concentrator, receiver, storage, * Utilization of solar energy for process heat and chemical reactions. Besides the continued development of terminal concentrators, the studies concentrated in 1991 on the development of solar chemistry processes. The reports of the activities were finalized recently and collected in the present volume. The final reports were printed as received. The achieved results and the views expressed within the reports were under the responsibility of the authors. As organizers of these solar thermal activities and as editors of the corresponding final reports, we would like to thank BMFT and KFA-BEO for the farsighted funding (grant no. 0328823A) and the research groups for their engagement and consultations. We would also like to thank Ms S. Preusser and Ms U. Rachow, who among many others contributed to the realization of this volume.

Ron Buckley's photographs show the changing locomotive scene taking place from the later 1930s throughout the East Midlands and East Anglia, illustrating pre-grouping locomotive classes still working across Lincoln, Cambridge, Norfolk, Suffolk, Nottingham, Leicester, Northampton, Bedford, Hertford, Buckingham and Essex. During later LNER days, locomotives of the Great Eastern and Great Northern Railways continued working the many secondary routes and branch lines while the main East Coast saw from 1935 the appearance of Nigel Gresley's streamlined class A4 locomotives working the high speed passenger traffic between Edinburgh and London. The LMS influence saw many former London and North Western and Midland Railway locomotives handling both passenger and goods traffic especially the product of the many collieries in Nottinghamshire.

An eminent early preservationist, John Crawley was able to amass an enviable photographic archive of steam traction engines and road rollers in their working days, of which this Aveling & Porter selection formed just a part. Organiser of over eighty steam rallies, John saved up to thirty steam traction engines for preservation from the mid-1950s to the early 1960s, at a time when they were considered not much more than worthless scrap. Indeed, he became the first owner of no fewer than twenty-two of them. Utilising this incredible and unique collection of images, most of which are previously unpublished, Colin Tyson tells the story of this important manufacturer and iconic British brand.

Lean burning of premixed gases is considered to be a promising combustion technology for future clean and highly efficient gas turbine combustors. Yet researchers face several challenges in dealing with premixed turbulent combustion, from its nonlinear multiscale nature and the impact of local phenomena to the multitude of competing models. Filling a gap in the literature, Fundamentals of Premixed Turbulent Combustion introduces the state of the art of premixed turbulent combustion in an accessible manner for newcomers and experienced researchers alike. To more deeply consider current research issues, the book focuses on the physical mechanisms and phenomenology of premixed flames, with a brief discussion of recent advances in partially premixed turbulent combustion. It begins with a summary of the relevant knowledge needed from disciplines such as thermodynamics, chemical kinetics, molecular transport processes, and fluid dynamics. The book then presents experimental data on the general appearance of premixed turbulent flames and details the physical mechanisms that could affect the flame behavior. It also examines the physical and numerical models for predicting the key features of premixed turbulent combustion. Emphasizing critical analysis, the book compares competing concepts and viewpoints with one another and with the available experimental data, outlining the advantages and disadvantages of each approach. In addition, it discusses recent advances and highlights unresolved issues. Written by a leading expert in the field, this book provides a valuable overview of the physics of premixed turbulent combustion. Combining simplicity and topicality, it helps researchers orient themselves in the contemporary literature and guides them in selecting the best research tools for their work.
