This book presents the ideas and industrial concepts in compact heat exchanger technology that have been developed in the last 10 years or so. Historically, the development and application of compact heat exchangers and their surfaces has taken place in a piecemeal fashion in a number of rather unrelated areas, principally those of the automotive and prime mover, aerospace, cryogenic and refrigeration sectors. Much detailed technology, familiar in one sector, progressed only slowly over the boundary into another sector. This compartmentalisation was a feature both of the user industries themselves, and also of the supplier, or manufacturing industries. These barriers are now breaking down, with valuable cross-fertilisation taking place.
One of the industrial sectors that is waking up to the challenges of compact heat exchangers is that broadly defined as the process sector. If there is a bias in the book, it is towards this sector. Here, in many cases, the technical challenges are severe, since high pressures and temperatures are often involved, and working fluids can be corrosive, reactive or toxic. The opportunities, however, are correspondingly high, since compacts can offer a combination of lower capital or installed cost, lower temperature differences (and hence running costs), and lower inventory. In some cases they give the opportunity for a radical re-think of the process design, by the introduction of process intensification (PI) concepts such as combining process elements in one unit. An example of this is reaction and heat exchange, which offers, among other advantages, significantly lower by-product production.
To stimulate future research, the author includes coverage of hitherto neglected approaches, such as that of the Second Law (of Thermodynamics), pioneered by Bejan and co- workers. The justification for this is that there is increasing interest in life-cycle and sustainable approaches to industrial activity as a whole, often involving exergy (Second Law) analysis. Heat exchangers, being fundamental components of energy and process systems, are both savers and spenders of exergy, according to interpretation.

This volume covers the computational dynamics of linear and non-linear engineering systems subject to conservative as well as non-conservative loads. Available in both paperback and hardback, the volume proposes an as simple as possible numerical evaluation of dynamic phenomena.

Practically all known methods of linear spectral analysis like the Householder, Givens, Wiland, Lanczos, Jacobi, Guyan, Eberlein, etc., are clearly detailed with a critical appraisal of their advantages and disadvantages. A great number of flow diagrams and examples are given in order to facilitate the understanding and practical application. A technically experienced reader will no doubt appreciate the interpretative difficulties of a subject like random or stochastic vibration expounded in a special chapter. Non-model damping is also detailed and the highly topical direct integration methods of the equations of dynamic equilibrium receive a very broad description.
p]
Finally non-linear oscillations are analysed mostly from the computational point of view. Here the Newmark and the Hermitean algorithms receive very detailed accounts and a critical appraisal. At the same time the subject of non-linear oscillations is introduced through a semi-analytical discussion of the Duffing equation in which the various attractor systems in phase space including strange attractors for chaotic manifestation are described.

This volume is the first to appear in this series of self-contained textbooks designed to present a modern, comprehensive account of computational mechanics, which will appeal to both student and experienced practitioner alike.

The International Conference on Mechanical Design and Production has been established since 1979 by the Department of Mechanical Design and Production at Cairo University.

The conference MDP-6 held in Cairo, 2-4 January 1996, represents the 6th in the series. Its aim was to highlight the current advances in mechanical design and production, and to disseminate the latest developments from academic and industrial institutions in all related scientific disciplines.

This publication includes a selection of papers submitted to the conference and reviewed by members of the scientific committee. The main areas of the papers include: materials processing and characterization constitutive modeling; simulation and analysis of manufacturing processes; numerical analysis of structures; fracture analysis; design and tribology; dynamics, control and robotics; and new trends in industrial and manufacturing engineering.

This volume contains 18 papers selected from 90 presented at the Fifth International Conference on Biaxial/Multiaxial Fatigue and Fracture held in Cracow, Poland 8-12 September 1997. The papers in this book deal with theoretical, computational and experimental aspects of the multiaxial fatigue and fracture of engineering materials and structures. The papers are divided into the following four categories:
1. Proportional cyclic loading
2. Non-proportional cyclic loading
3. Variable amplitude and random loading
4. Crack growth

Most papers in this publication talk about the behaviour of constructional materials and elements of machines under non-proportional loading and under variable amplitude and random loading, which are more realistic load histories met in industrial practice. Variable amplitude loading under cyclic load with basic frequency and random loading under load with a continuous band of frequency is classified here. This book gives a review of the latest world success and directions of investigations on multiaxial fatigue and fracture. More and more often publications are results of the co-operation of researchers from different laboratories and countries. Seven out of eighteen papers included here were worked out by international authors teams. This is a symptom of the times, when science and investigations know no borders.

This is an abridged edition of the author's previous two-volume work, Ring Theory, which concentrates on essential material for a general ring theory course while ommitting much of the material intended for ring theory specialists. It has been praised by reviewers: **"As a textbook for graduate students, Ring Theory joins the best....The experts will find several attractive and pleasant features in Ring Theory. The most noteworthy is the inclusion, usually in supplements and appendices, of many useful constructions which are hard to locate outside of the original sources....The audience of nonexperts, mathematicians whose speciality is not ring theory, will find Ring Theory ideally suited to their needs....They, as well as students, will be well served by the many examples of rings and the glossary of major results."**--NOTICES OF THE AM

The 24th Leeds-Lyon Symposium was held in London from 4th-6th September 1997, where it was hosted by the Imperial College of Science, Technology and Medicine.

The meeting addressed the topic of "Tribology for Energy Conservation" and attracted a wide range of stimulating papers and speakers. Some 150 delegates from nineteen countries attended and about sixty papers were presented in fifteen sessions. These covered the topics of lubricants, wear, friction reduction, hydrodynamics, elastohydrodynamic lubrication, surface roughness, manufacturing, component life (including condition monitoring), and automotive aspects.

In the 1970s and the early 1980s there was an enormous volume of research and development into the subject of molybdenum disulphide lubrication, much of which was supported by national governments for the benefit of defence, aviation or space activities. There were already some well-established practical guidelines for deciding when and how to use molybdenum disulphide, but there was still a considerable lack of universally-accepted theoretical understanding of some of the important and fundamental aspects of molybdenum disulphide technology. However, the state of knowledge was growing rapidly.

In the past fifteen years the situation with regard to the technology of molybdenum disulphide lubrication has stabilised in many respects, and a measure of consensus has been reached about some of the mechanisms involved. The use of molybdenum disulphide has become routine in some industries, and there are many well-established and reputable commercial products available. Except in the high-technology field of physical deposition techniques, especially sputtering, the output of new research publications has fallen from perhaps two hundred a year in the 1970s to fewer than ten a year in the 1990s. In spite of this maturing of the subject, it is clear that there are still many aspects in which disagreements persist about the mechanisms involved, and which as a result are unclear or misunderstood among current, and perhaps even more importantly, potential users.
One of the primary objectives of this book is to analyse the various aspects of molybdenum disulphide lubrication technology about which there are still disagreements or controversy, and to attempt to come to firm conclusions about some of the mechanisms involved. In particular, it will place emphasis on the importance and effects of burnishing and film consolidation.

Each chapter is accompanied by a real life' case study.
First book published solely dealing with heat and fluid flow in minichannels and microchannels.

The direct conversion of daylight into electricity by photovoltaic solar cells is one of the most promising of the renewable energy options. The importance of the technology is reflected in the growth in the field. What was largely technology for space programmes in 1976 produced 28.6 MW of terrestrial modules in 1987. The popularity of the technology can partly be explained by its versatility. Arrays of any size and voltage can be constructed from standard modules, with the conversion efficiency being practically independent from output. Photovoltaics are also well suited to on-site generation of power in remote areas. This book is intended primarily to give students, engineers and scientists entering the photovoltaics field an overview of all aspects of the subject, with pointers to further reading. However, by using simple language and avoiding jargon, an effort has been made to make the work useful and interesting to the general public.

This handbook will enable you to understand the various designs and properties of leak-free pumps and select the right pump or compressor to ensure leak free systems whatever the application.

Mastering modelling, and in particular numerical models, is becoming a crucial and central question in modern computational mechanics. Various tools, able to quantify the quality of a model with regard to another one taken as the reference, have been derived. Applied to computational strategies, these tools lead to new computational methods which are called "adaptive." The present book is concerned with outlining the state of the art and the latest advances in both these important areas.

Papers are selected from a Workshop (Cachan 17-19 September 1997) which is the third of a series devoted to Error Estimators and Adaptivity in Computational Mechanics. The Cachan Workshop dealt with latest advances in adaptive computational methods in mechanics and their impacts on solving engineering problems. It was centered too on providing answers to simple questions such as: what is being used or can be used at present to solve engineering problems? What should be the state of art in the year 2000? What are the new questions involving error estimators and their applications?

Generally, welding produces welding deformation and residual stress in the products, which influences the quality and performance of the products. Although many engineers and researchers have made great effort how to control these incidents, they have still remained unresolved. "Welding Deformation and Residual Stress Prevention" provides a unique computational approach to the prediction of the effects of deformation and residual stress on materials. The goal is to provide engineers and designers with the ability to create their own computational system for predicting and possibly avoiding the problem altogether.
The basic theories including "theory of elastic-plastic analysis" and "inherent strain theory," and analysis procedures are described using a simple three-bar model.

This book provides in a single and unified volume a clear and thorough presentation of the recent advances in continuum damage mechanics for metals and metal matrix composites. Emphasis is placed on the theoretical formulation of the different constitutive models in this area, but sections are added to demonstrate the applications of the theory. In addition, some sections contain new material that has not appeared before in the literature.
The book is divided into three major parts: Part I deals with the scalar formulation and is limited to the analysis of isotropic damage in materials; Parts II and III deal with the tensor formulation and is applied to general states of deformation and damage.
The material appearing in this text is limited to plastic deformation and damage in ductile materials (e.g. metals and metal matrix composites) but excludes many of the recent advances made in creep, brittle fracture, and temperature effects since the authors feel that these topics require a separate volume for this presentation. Furthermore, the applications presented in this book are the simplest possible ones and are mainly based on the uniaxial tension test.
