FUNDAMENTALS OF HEAT
EXCHANGER DESIGN
The objective of this book is to provide in-depth thermal and hydraulic design theory of two-fluid single-phase heat exchangers for steady-state operation. Three important goals were borne in mind during the preparation of this book:
1. To introduce and apply concepts learned in first courses in heat transfer, fluid mechanics, thermodynamics, and calculus, to develop heat exchanger design theory. Thus, the book will serve as a link between fundamental subjects mentioned and thermal engineering design practice in industry.
2. To introduce and apply basic heat exchanger design concepts to the solution of industrial heat exchanger problems. Primary emphasis is placed on fundamental concepts and applications. Also, more emphasis is placed on analysis and less on empiricism.
3. The book is also intended for practicing engineers in addition to students. Hence, at a number of places in the text, some redundancy is added to make the concepts clearer, early theory is developed using constant and mean overall heat transfer coefficients, and more data are added in the text and tables for industrialuse.
To provide comprehensive information for heat exchanger design and analysis in a book of reasonable length, we have opted not to include detailed theoretical derivations
of many results, as they can be found in advanced convection heat transfer textbooks. Instead, we have presented some basic derivations and then presented comprehensive information through text and concise tables.
An industrial heat exchanger design problem consists of coupling component and system design considerations to ensure proper functioning. Accordingly, a good design engineer must be familiar with both system and component design aspects. Based on industrial experience of over three decades in designing compact heat exchangers for automobiles and other industrial applications and more than twenty years of teaching, we have endeavored to demonstrate interrelationships between the component and system design aspects, as well as between the needs of industrial and learning environments. Some of the details of component design presented are also based on our own system
design experience.
