Book excerpt: Many cryogenic heat exchangers employ high-conductance metallic screens or perforated plates separated by insulating spacers normal to the fluid flow direction. The former insures a high rate of heat transfer between the fluid streams while the latter reduces longitudinal conduction. Packed-bed regenerators employing wire screens, perforated plates, or granular particles also have a similar structure. In these exchangers, any individual plate or particle has very high thermal conductivity and is essentially at a single temperature. As a result, the temperature profile along the length consists of many steps, rather than a single continuous curve. Conventional analysis based on a continuous temperature profile tends to overestimate the efficiency of these exchangers. Axial conduction down the bed, caused by finite contact or spacer resistance, further reduces the effectiveness. The ineffectiveness due to axial conduction adds to that due to finite number of plates and finite heat transfer coefficient. A closed form expression is derived for the efficiency of a compact heat exchanger with given design N/sub tu/ where the exchanger consists of layers of metallic screens, plates, or particle layers. It is observed that the effect of discrete temperature profile becomes significant when the per stage design N/sub tu/ exceeds about 0.5.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Heat Exchanger Design, Second Edition builds upon the widely-used First Edition, a text often considered to be the most prominent single-volume heat exchanger text on the market. The new and improved Second Edition serves as an equally comprehensive resource, updated to suit the latest technologies and design methods being used in the Heat Exchanger field. Written by First-Edition author Dusan P. Sekulic, this text addresses the latest developments in the industry, including a brand-new chapter on the manufacturing of compact heat exchangers. After opening with a basic introduction to heat exchanger types and design methods, the book goes on to cover more specialized topics such as such as the design of recuperators and regenerators, pressure drop analysis, geometric properties, flow friction, fouling and corrosion, and more. With many significant revisions throughout, this new edition offers more streamlined content while maintaining the consistent, detailed coverage of the fundamentals of the topic that readers appreciated in the First Edition. These unique features position the Second Edition of Fundamentals of Heat Exchanger Design as the ideal text for both engineering professionals and advanced students alike.
