A cutting-edge update to the most essential single-volume resource on the market
Heat exchangers are thermal devices which transfer heat between two or more fluids. They are integral to energy, automotive, aerospace, and myriad other technologies. The design and implementation of heat exchangers is an essential skill for engineers looking to contribute to a huge range of applications.
Fundamentals of Heat Exchanger Design, Second Edition provides a comprehensive insight into the design and performance of heat exchangers. After introducing the basic heat transfer concepts and parameters, an overview of design methodologies is discussed. Subsequently, details of design theory of various types of exchangers are presented. The first edition established itself as the standard single-volume text on the subject. The second edition preserves an established in-depth approach but reflects some new technological developments related to design for manufacturing compact heat exchangers, including novel 3-D printing approaches to heat exchanger design.
Readers of the second edition of Fundamentals of Heat Exchanger Design will also find: - A new section on the design for manufacturing of compact heat exchangers - A new section on design for additive manufacturing compact heat exchangers - Detailed discussions of the design of recuperators and regenerators, pressure drop analysis, geometric parameters, heat transfer correlations, and more
Fundamentals of Heat Exchanger Design is ideal for practicing engineers, as well as for advanced undergraduate and graduate students in mechanical and aerospace engineering, energy engineering, and related subjects.
