Significantly revised and updated since its first publication in 1996, Absorption Chillers and Heat Pumps, Second Edition discusses the fundamental physics and major applications of absorption chillers. While the popularity of absorption chillers began to dwindle in the United States in the late 1990's, a shift towards sustainability, green buildings and the use of renewable energy has brought about a renewed interest in absorption heat pump technology. In contrast, absorption chillers captured a large market share in Asia in the same time frame due to relative costs of gas and electricity. In addition to providing an in-depth discussion of fundamental concepts related to absorption refrigeration technology, this book provides detailed modeling of a broad range of simple and advanced cycles as well as a discussion of applications. New to the Second Edition: * Offers details on the ground-breaking Vapor Surfactant theory of mass transfer enhancement * Presents extensively revised computer examples based on the latest version of EES (Engineering Equation Solver) software, including enhanced consistency and internal documentation * Contains new LiBr/H2O property routines covering a broad range of temperature and the full range of concentration * Utilizes new NH3/H2O helper functions in EES which significantly enhance ease of use * Adds a new chapter on absorption technology applications * Offers updated absorption fluid transport property information Absorption Chillers and Heat Pumps, Second Edition provides an updated and thorough discussion of the physics and applications of absorption chillers and heat pumps. An in-depth guide to evaluating and simulating absorption systems, this revised edition provides significantly increased consistency and clarity in both the text and the worked examples. The introduction of the vapor surfactant theory is a major new component of the book. This definitive work serves as a resource for both the newcomer and seasoned professional in the field.
This book focuses on Nuclear-Pumped Laser (NPL) technology and provides the reader with a fundamental understanding of NPLs, a review of research in the field and exploration of large scale NPL system design and applications.
Early chapters look at the fundamental properties of lasers, nuclear-pumping and nuclear reactions that may be used as drivers for nuclear-pumped lasers. The book goes on to explore the efficient transport of energy from the ionizing radiation to the laser medium and then the operational characteristics of existing nuclear-pumped lasers. Models based on Mathematica, explanations and a tutorial all assist the reader's understanding of this technology.
Later chapters consider the integration of the various systems involved in NPLs and the ways in which they can be used, including beyond the military agenda. As readers will discover, there are significant humanitarian applications for high energy/power lasers, such as deflecting asteroids, space propulsion, power transmission and mining.
This book will appeal to graduate students and scholars across diverse disciplines, including nuclear engineering, laser physics, quantum electronics, gaseous electronics, optics, photonics, space systems engineering, materials, thermodynamics, chemistry and physics.
Centrifugal pump technology involves a broad spectrum of flow phenomena, which have a profound impact on design and operation through the achieved efficiency, the stability of the head-capacity characteristic, component failure due to fatigue, as well as material damage caused by cavitation, hydro-abrasive wear or erosion corrosion. Operation and life cycle costs of pumping equipment depend to a large extent on how well these phenomena and the interaction of the pump with the system are understood. The book comprises thirteen chapters covering: theory of centrifugal pump impeller, design of mixed flow impellers, pump casing, hydraulic performance, leakage-disk friction and mechanical losses, water hammer, special operating conditions, and its applications. The book also describes cavitation in pumps, and how unacceptable cavitation can be avoided with the aid of an inducer or using a bleeding system. It explains cavitation problems such as hydraulic performance loss, hydro-dynamically or thermodynamically induced surging, and cavitation erosion/corrosion. The book aims to be simple as is compatible with reasonably complete treatment of the subject. The mathematics has been kept as elementary as possible and many of the standard proofs have been simplified. This book is intended for professional engineers, researchers, specialist students, plant operators and maintenance personnel, plant engineers, and consulting engineers.
Per-Olov Lâ€wdin's stature has been a symbol of the world of quantum theory during the past five decades, through his basic contributions to the development of the conceptual framework of Quantum Chemistry and introduction of the fundamental concepts; through a staggering number of regular summer schools, winter institutes, innumerable lectures at Uppsala, Gainesville and elsewhere, and Sanibel Symposia; by founding the International Journal of Quantum Chemistry and Advances in Quantum Chemistry; and through his vision of the possible and his optimism for the future, which has inspired generations of physicists, chemists, mathematicians, and biologists to devote their lives to molecular electronic theory and dynamics, solid state, and quantum biology.
Fundamental World of Quantum Chemistry: Volumes I, II and III form a collection of papers dedicated to the memory of Per-Olov Lâ€wdin. These volumes are of interest to a broad audience of quantum, theoretical, physical, biological, and computational chemists; atomic, molecular, and condensed matter physicists; biophysicists; mathematicians working in many-body theory; and historians and philosophers of natural science. The volumes will be accessible to all levels, from students, PhD students, and postdocs to their supervisors.
Squashes and pumpkins come in many shapes and sizes, and they are particularly tasty when home-grown and eaten soon after harvesting. In this book, the main types are described and illustrated, from marrows and pattypan squashes to butternut squashes and cucumbers. There is key advice on growing and caring for each type, how to harvest and store them, and how to keep plants in good condition by dealing with any pests and diseases. There is also advice on how to carve squashes and pumpkins to make lanterns and other decorations. The book provides reliable information for all gardeners who would like to experiment with new varieties. An illustrated gardener's guide to the different varieties of squashes and pumpkins, their history and cooking uses Step-by-step instructions for preparing the soil, growing under glass, providing support, harvesting and storing Practical advice and tips on cultivating marrows, courgettes and zucchini, pumpkins, squashes and cucumbers in the garden Helpful hints on how to avoid pests and diseases, and what to do when problems occur LORENZ BOOKS An imprint of Anness Publishing Ltd. www.annesspublishing.com; firstname.lastname@example.org Lorenz
