Book Synopsis Liquid Helium Technology by : Sam Stuart
Download or read book Liquid Helium Technology written by Sam Stuart and published by Elsevier. This book was released on 2014-12-03 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pure and Applied Cryogenics, Volume 6: Liquid Helium Technology focuses on the principles, techniques, methodologies, and approaches involved in liquid helium technology. The selection examines liquid helium technology at the National Bureau of Standards, properties of liquid helium, heat transfer to liquid helium, and noise associated with heat transfer to liquid helium II. Discussions focus on apparatus and instrumentation, test procedure, liquid helium as a cryogenic liquid, zero viscosity, momentum of heat flow, rotation and vortex lines, oscillation of vortex lines, and quantized vortices. The publication then takes a look at boiling heat transfer to liquid helium, heat transfer from metal to supercritical helium, heat transfer to boiling liquid helium in narrow vertical channels, and critical nucleate boiling of liquid helium in a simulated wire wound magnet. The text ponders on microdegree temperature controller for liquid helium II bath, commercial production, storage and distribution of liquid helium, lightweight liquid helium dewar, commercial handling of liquid helium dewars, effectiveness of low temperature refrigeration for electronics, and a bulk liquid helium distribution system. The selection is a valuable source of information for scientists and researchers interested in liquid helium technology.

Book Synopsis The Effects of Electric Fields on the Flow of Liquid Helium by : W. Jim Neidhardt
Download or read book The Effects of Electric Fields on the Flow of Liquid Helium written by W. Jim Neidhardt and published by . This book was released on 1962 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made of the effect of electric fields on the flow of liquid helium in a narrow channel superleak whose exit was maintained at a pressure far below the vapor pressure of the liquid. Liquid helium evaporation in the channel and the resulting liquid-gas interface caused an electric pressure gradient. It was found that electric fields of magnitude 3,000,000 volts/cm did not destroy the superfluidity exhibited in the channel. The effect of the applied electric field was to increase flow above and below the lamboa point. Below the lamboa point, both the normal and the superfluid flows were increased by the applied field. At very high applied field the flow attained a limiting value which was a function of temperature.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Heat Transfer and Flow of Helium in Channels: Practical Limits for Applications in Superconductivity The development of large superconducting devices is intimately related to the fluid mechanics and heat transfer characteristics of cryogenic helium. In the earliest successfully developed magnets for bubble chambers and accelerator beam transport and focussing, the main function of the helium was to cool the conductor matrix down, to stabilize it against flux jumps, and to provide a heat sink for the relatively low losses which occur in charging. The success of this phase of development of superconducting technol ogy is attested to by the existence of several such devices with 1000 hours or more of routine operation behind them The wide range of applications under consideration for the future, however, demands much more of the helium as a heat transfer medium, and will exercise the ingenuity of designers to the full. The simple expedient of immersing a device in a bath of liquid helium at a temperature close to 4 K will not suffice or may simply be impractical. Our research philosophy at the National Bureau of Standards has been to explore as far as possible all modes of application of helium as a heat transfer medium in order to preserve as many options as possible for the designer. As a consequence we are interested in all phases of helium and we are particularly interested in exploring the possible boundaries of operation imposed by the thermodynamic and transport properties of helium. In this paper, after a brief discussion of the relevant properties of helium, we consider some important characteristics of helium flowing in channels, since we anticipate that this mode of cooling in some form or other will be preferred over natural convection in future large devices. First we discuss heat transport to helium I above the critical pressure, then heat transport to helium I below the critical pressure. We then discuss some possibilities for cooling to lower temperatures by means of helium II. In the final section we consider the problem of flow stability and oscillations in channels cooled by forced flow of helium.

This book was released on 1991-12-16 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid helium has been studied for its intrinsic interest through much of the 20th century. In the past decade, much has been learned about heat transfer in liquid helium because of the need to cool superconducting magnets and other devices. The topic of the Seventh Oregon Conference on Low Temperature Physics was an applied one, namely the use of liquid and gaseous helium to generate high Reynolds number flows. The low kinematic viscosity of liquid helium automatically makes high Reynolds numbers accessible and the question addressed in this conference was to explore various possibilities to see what practical devices might be built using liquid or gaseous helium. There are a number of possibilities: construction of a wind tunnel using critical helium gas, free surface testing, low speed flow facilities using helium I and helium ll. At the time of the conference, most consideration had been given to the last possibility because it seemed both possible and useful to build a flow facility which could reach unprecedented Reynolds numbers. Such a device could be useful in pure research for studying turbulence, and in applied research for testing models much as is done in a water tunnel. In order to examine these possibilities in detail, we invited a wide range of experts to Eugene in October 1989 to present papers on their own specialties and to listen to presentations on the liquid helium proposals.
