**VI** Contents

This book presents contributions from renowned experts addressing research and develop‐ ment related to the major advanced features and fields of application of heat exchangers. It consists of nine chapters. Except the introductory chapter, which brings in perspective and overviews of the content of the book, the first three chapters start with advanced design and geometry features related to different kinds of heat exchangers; the next chapters deal with the use of compressible and supercritical thermal fluids followed by two chapters present‐ ing two special applications and ending with advances in treating the problems of fouling and corrosion in heat exchangers.

This book starts with an introductory chapter giving a perspective of the importance of the heat exchanger technology and also highlighting all the contributions of this book, provid‐ ing some complementary information.

The second chapter covers the two-phase flow pressure drop and heat transfer of a refriger‐ ant during boiling in macroscale and miniscale channel-based heat exchangers.

The third chapter presents the study of the performance of compact heat exchangers with offset strip fin using different offset strip geometries.

The same authors follow in the fourth chapter with the description of the basic physical fea‐ tures and the analysis of the performance of the heat exchangers with louvered fins.

The fifth chapter reports the current state of knowledge of free-convection condensation heat transfer on geometrically enhanced tubes. It reports extensive comparative experimen‐ tal work performed on integral and enhanced pin-fin tubes demonstrating that geometry is not the only factor for enhancement of heat transfer.

An extensive study on the heat transfer between supercritical fluid flows and solid walls and also between compressible flows and solid walls is presented in the sixth chapter. It also introduces some practical applications of heat exchangers using supercritical fluid flows and/or compressible flows.

The seventh chapter highlights methods for the design and the choice of heat exchangers to be used in aeronautical applications and provides some practical case studies.

The eighth chapter gives brief overview of the steam generators used in nuclear power plants, their design, operation, and the correlations used to quantify heat transfer in these devices.

The final chapter underlines the importance of corrosion control, fouling cleaning, and en‐ forcement of specific standards for maintenance and cleaning procedures in industries. It also proposes the application of a mitigation approach to deal with fouling and corrosion.

This book is intended to be a useful source of information for researchers, postgraduate stu‐ dents, academics, as well as designers and engineers working in the fields of heat exchang‐ ers and related industries.

We would like to thank all the authors for their high-quality contributions and the publish‐ ing process manager for providing continuous support, which have made possible the com‐ pletion of this book.

Finally we would like to express our appreciation to our family members for their continued support and patience during the preparation of this book.
