This monograph summarizes the findings from 650 references devoted to heat transfer and hydraulic resistance of fluids flowing inside channels of various geometries at critical and supercritical pressures. The objectives are to assess the work that was done for the last fifty years in these areas, to understand the specifics of heat transfer and hydraulic resistance, and to propose the most reliable correlations to calculate the heat transfer coefficient and total pressure drop at these conditions.

Using SuperCritical Fluids (SCFs) in various processes is not new, because Mother Nature has been processing minerals in aqueous solutions at critical and supercritical pressures for billions of years. Somewhere in the 20th century, SCFs started to be used in various industries as working fluids, coolants, chemical agents, etc. Written by an international team of experts and complete with the latest research, development, and design, Advanced Supercritical Fluids Technologies is a unique technical book, completely dedicated to modern and advanced applications of supercritical fluids in various industries.Advanced Supercritical Fluids Technologies provides engineers and specialists in various industries dealing with SCFs as well as researchers, scientists, and students of the corresponding departments with a comprehensive overview of the current status, latest trends and developments of these technologies.Dr Igor Pioro is a professor at the University of Ontario Institute of Technology, Canada, and the Founding Editor of the ASME Journal of Nuclear Engineering and Radiation Science.

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.
