Dewar
A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...
Stirling and Gifford-McMahon Cryocoolers
Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...
Liquefied Natural Gas (LNG)
A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...
Wind Tunnels
Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...
History of Cryogenics
From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...
Cryobiology
Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...
Cryogenic Insulation
James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...
Any experience with Tungsten or Tantalum metal springs in a low temp environment?
I would like to use metal springs made of Tungsten or Tantalum in low temperature environment. Does anybody have any experience with such springs? More precisely, I would like to make compression springs by rolling tungsten or tantalum wire on a rod. I expect that, typically, the spring constant will...
Standards & specifications for pipe & tube couplings
I am interested in finding out more about cryogenic applications and what standards, specifications and test methods (ASTM, etc.) are required for qualification of pipe and tube couplings.
Looking for a test house to test the static coefficient of friction under cryogenic conditions
I am looking to find a test house that is capable of testing the static coefficient of friction under cryogenic conditions. We can be flexible on most of the test parameters, including the test coupon configuration, but we’re looking for a test house that can provide the following test environment:...
Approximating pressure changes over time in cryogenic cylinders
I am an Air Resources Engineer with the California Air Resources Board (CARB). My senior management has asked me to investigate approximating pressure changes over time in cryogenic cylinders that contain LNG. So far, I have taken a stab at the problem, seeking to take a back-of-the-envelope approach (as directed...
