An in-depth survey of regenerative heat exchangers, this book chronicles the development and recent commercialization of regenerative devices for cryogenic applications. Chapters cover historical background, concepts, practical applications, design data, and numerical solutions, providing the latest information for engineers to develop advanced cryogenic machines. The discussions include insights into the operation of a regenerator; descriptions of the cyclic and fluid temperature distributions in a regenerator; data for various matrix geometries and materials, including coarse and fine bronze, stainless steel-woven wire mesh screens, and lead spheres; and unique operating features of cryocoolers that produce deviations from ideal regenerator theory.

Publisher Description

Cryogenic engineering (cryogenics) is the production, preservation, and use or application of cold. This book presents a comprehensive introduction to designing systems to deal with heat – effective management of cold, exploring the directing (or redirecting), promoting, or inhibiting this flow of heat in a practical way. It provides a description of the necessary theory, design methodology, and advanced demonstrations (thermodynamics, heat transfer, thermal insulation, fluid mechanics) for many frequently occurring situations in low-temperature apparatus. This includes systems that are widely used such as superconducting magnets for magnetic resonance imaging (MRI), high-energy physics, fusion, tokamak and free electron laser systems, space launch and exploration, and energy and transportation use of liquid hydrogen, as well as potential future applications of cryo-life sciences and chemical industries. The book is written with the assumption that the reader has an undergraduate understanding of thermodynamics, heat transfer, and fluid mechanics, in addition to the mechanics of materials, material science, and physical chemistry. Cryogenic Heat Management: Technology and Applications for Science and Industry will be a valuable guide for those researching, teaching, or working with low-temperature or cryogenic systems, in addition to postgraduates studying the topic. Key features: Presents simplified but useful and practical equations that can be applied in estimating performance and design of energy-efficient systems in low-temperature systems or cryogenics Contains practical approaches and advanced design materials for insulation, shields/anchors, cryogen vessels/pipes, calorimeters, cryogenic heat switches, cryostats, current leads, and RF couplers Provides a comprehensive introduction to the necessary theory and models needed for solutions to common difficulties and illustrates the engineering examples with more than 300 figures

The University of Colorado and the National Bureau of Standards have once again served as hosts for the Cryogenic Engineering Conference in Boulder, Colorado. In presenting the papers of this twelfth annual meeting, the 1966 Cryogenic Engineering Conference Committee has again recognized the excellent cooperation which has existed between these two organizations over the past decade with regard to both cryogenic research and conference activity. This cooperation was demonstrated not only at the 1966 Cryogenic Engineering Conference but also at the International Institute of Refrigeration, Commission I Meeting, which was also hosted by these two organizations immediately following the Cryogenic Engineering Conference. These two meetings have provided attendees with one of the most comprehensive coverages of cryogenic topics that has ever been presented at one location. Emphasis on major international advances in helium technology at the International Institute of Refrigeration, Commission I Meeting has been possible largely through the National Science Foundation Grant GK 1116 to the University of Colorado. The Cryogenic Engineering Conference Committee gratefully acknowledges this support because of its valuable international contribution to the Cryogenic Engineering Conference. As in the past, the Cryogenic Engineering Conference Committee is grateful for the continued assistance of all the dedicated workers in the cryogenic field who have contributed their time reviewing the preliminary papers for the program and the final manuscripts for this volume.
