Cryogenic Helium Refrigeration For Middle And Large Powers

de Guy Gistau Baguer

145,09€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 <p>This book offers a practical introduction to helium refrigeration engineering, taking a logical and structured approach to the design, building, commissioning, operation and maintenance of refrigeration systems.</p><p>It begins with a short refresher of cryogenic principles, and a review of the theory of heat exchangers, allowing the reader to understand the importance of the heat exchanger role in the various thermodynamic cycle structures. The cycles are considered from the simplest (Joule Thomson) to the most complicated ones for the very large refrigeration plants and, finally, those operating at temperatures lower than 4.5 K.</p>The focus then turns to the operation, ability and limitations of the main components, including room temperature cycle screw compressors, heat exchangers, cryogenic expansion turbines, cryogenic centrifugal compressors and circulators. The book also describes the basic principles of process control and studies the operating situations of helium plants, with emphasis on high level efficiency.<p></p><p>A major issue is helium purity, and the book explains why helium is polluted, how to purify it and then how to check its purity, to ensure that all components are filled with pure helium prior to starting.</p><p>Although the intention of the book is not to design thermodynamic cycles, it is of interest to a designer or operator of a cryogenic system to perform some simplified calculations to get an idea of how components or systems are behaving. Throughout the book, such calculations are generally performed using Microsoft® Excel and the Gaspak® or Hepak® software. </p>

184,84€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The revised second edition of this practical book reviews the fundamentals of cryogenic liquid behaviour in small and large scale storage systems. The text is based on research findings on the convective and evaporative behaviour of cryogenic fluids, aimed at improving the design, construction and operation of low-loss cryogenic liquid storage systems, with a view to minimising cost and improving operational safety.<div><br></div><div>Since the first edition was published in 2006, the breadth of cryogenic applications and the modelling of cryogenic fluid dynamics (CFD) have expanded in several directions. In this second edition, most chapters have been extended to introduce discussions of these new applications and their safety and energy economy. These include advances in the modelling of CFD required in, for example, the design of miniature cryocoolers and condensers and reboilers, large-scale cryogenic liquid mixture properties and their stability, and the understanding that hazardsand safety problems in the public domain increase with the scaling up of cryogenic systems.</div><div><br></div><div>With helpful summaries at the end of each chapter, the book is an essential reference for anyone working on the design and operation of cryogenic liquid storage and transportation systems.</div>

Helium Cryogenics

de Steven W. Van Sciver

95,40€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 At least 10 years have elapsed since a comprehensive monograph concer ned with the broad subject of cryogenics has been published. During this time a considerable quantity of research and development has been carried out in the field of cryogenics. Furthermore, there has been a certain degree of redirection of effort within the field, mostly driven by the variety of new applications, ranging from superconductive magnet systems to micro electronics. Greater emphasis is now being placed on low-temperature cryogenics, particularly that of liquid helium. Until now cryogenic books have provided a broad survey of materials and fluid properties over the entire cryogenic regime, T ::5 150 K. This approach does not allow sufficient detail in any particular area to bring the reader to the current level of understanding in the subject. In addition, the behavior of helium has been lumped with that of other cryogenic fluids, although the properties of helium are quite unique. As a result, a clear relationship has not been established between the fundamental understanding of helium fluids and their potential applications. The present book has been written to fill this void. The approach is to survey the field of cryogenics, specifically as it pertains to helium fluids. This approach is more specialized than that contained in previous cryogenics books. Furthermore, the level of treatment is more advanced and a certain knowledge of fundamental engineering and physics principles has been assumed.

Modern Gas-Based Temperature And Pressure Measurements

de Franco Pavese e Gianfranco Molinar Min Beciet

95,40€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Since the beginning of the preparation of this volume, we have been convinced that temperature and pressure measurements should not be separated, particularly in different applications at low temperatures. This belief has made us deeply conscious of the fact that the advanced applications and modern experimental methods of investigation in science and technology need the combination of various professional experiences and approaches. Although the book is divided into two parts (Part I by F. Pavese and Part II by G. F. Molinar), we have tried to correlate low-temperature and low-pressure measurements as much as possible. We hope that our readers will find this book, which contains a large number of experimental and reference data, useful in their effort to solve measurement problems. We are pleased to acknowledge our debt to several persons and wish to express our gratitude to them for their valuable cooperation and help: to our research group colleagues at the Istituto di Metrologia "G. Colonnetti" -IMGC (CNR), without whom the knowledge and the experience we built up during many years could not have been acquired; to G. T. McConville, M. Durieux, and K. Grohmann for revisions of and various suggestions for Part I; to V. E. Bean and C. R. Tilford of NIST and G. T. McConville for revisions of and various suggestions for Part II; and to I. Prinetti of IMGC for many valuable suggestions and careful textual revisions.

Heat Capacity And Thermal Expansion At Low Temperatures

de G.K. White e T.H.K. Barron

171,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The birth of this monograph is partly due to the persistent efforts of the General Editor, Dr. Klaus Timmerhaus, to persuade the authors that they encapsulate their forty or fifty years of struggle with the thermal properties of materials into a book before they either expired or became totally senile. We recognize his wisdom in wanting a monograph which includes the closely linked properties of heat capacity and thermal expansion, to which we have added a little 'cement' in the form of elastic moduli. There seems to be a dearth of practitioners in these areas, particularly among physics postgraduate students, sometimes temporarily alleviated when a new generation of exciting materials are found, be they heavy fermion compounds, high- temperature superconductors, or fullerenes. And yet the needs of the space industry, telecommunications, energy conservation, astronomy, medical imaging, etc. , place demands for more data and understanding of these properties for all classes of materials - metals, polymers, glasses, ceramics, and mixtures thereof. There have been many useful books, including Specific Heats at Low Tempera- tures by E. S. Raja Gopal (1966) in this Plenum Cryogenic Monograph Series, but few if any that covered these related topics in one book in a fashion designed to help the cryogenic engineer and cryophysicist. We hope that the introductory chapter will widen the horizons of many without a solid state background but with a general interest in physics and materials.
