Cryogenic Treatment Applications Find Potential in the Energy Sector

Energy Sector and Metallic MaterialsSimultaneously improving known materials and exploring new alternative material options for applications in demanding environments for the energy sector (offshore wind power, solar power, biomass power, fission and fusion, geothermal power, hydroelectric power) is one of the leading engineering research endeavors today[1]. A unique combination of...

Inside ORNL’s Second Target Station’s Cryogenic Moderator Design

The Second Target Station (STS) is the future of forefront neutron scattering science at Oak Ridge National Laboratory, which started with the first neutron scattering measurements in the 1940s at the X-10 Graphite Reactor and continues today at the High Flux Isotope Reactor (HFIR) and Spallation Neutron Source (SNS). STS...

Scientists Elucidate Heat Flows in Liquid Hydrogen Tanks

Hydrogen has been touted as the fuel of the future, but challenges remain in improving the storage efficiency of liquefied hydrogen fuel for large scale commercial transport and storage. Researchers from South Korea have conducted experiments and simulations to investigate the heat flows and phase changes within a cryogenic fuel...

Tackling the Rapidly Expanding Hydrogen Power Industry

PBS Velka Bites has been in the cryogenic business for more than 35 years. Today, its cryogenics engineering capabilities include everything from preliminary calculation through design, manufacturing and assembly, to testing and user optimization of its cryogenic products. Since the late ’80s, PBS has been developing and supplying cryogenic turbines...

Understanding the Origin of Matter with the CUORE Experiment

The Cryogenic Underground Observatory for Rare Events (CUORE) can search for these rare NLDBD processes using different nuclei. Scientists rely on complementarity among searches using different nuclei to have a better understanding of the underlying physics in the process. Complementarity in physics involves theories that contrast with each other but...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
