Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

CEC/ICMC 2017 Conference Recap

Nestled against the coast of lake Monona in Madison WI, over 700 scientists and engineers from around the world bustled around the meeting rooms of Frank Lloyd Wright’s Monona Terrace from July 9-13, 2017, for the 21st joint Cryogenic Engineering and International Cryogenic Materials Conferences.

Flaw Uncovered in Modern Cryogenic Two-phase Flow Modeling

An investigation into popular thermal/fluid design codes begun as an exercise in curiosity by engineers at NASA Glenn Research Center and the University of Florida has uncovered an interesting flaw in modern cryogenic two-phase flow modeling.

Liquid Air Energy Storage: How Cryogenics Can Support a Greener Grid

The LAES system charges using an industrial air liquefier based on the Claude cycle used on the front end of existing air separation units. Electricity from the grid is used to produce liquid air at close to ambient pressure, thus avoiding the excessive cost of containing a high-pressure fluid in...

VNR Advances New Process to Ensure Reliability of Space-Flight-Critical Fasteners

In October 1989, while investigating the crash landing of United Flight 232 in Sioux City, the NTSB located the fan disk from the plane’s number two engine in a cornfield near Alta, Iowa. It was in two pieces, ripped apart, the agency later determined, when an undetected metallurgical defect resulted...

Chart Acquires VCT Vogel

On September 1, Chart Industries, Inc. (CSA CSM) announced its acquisition of VCT Vogel GmbH, a German firm servicing cryogenic and other mobile gas tank equipment and trucks. Founded in 2001, VCT has established itself as a provider of truck-mounted drive and control systems for the operation of cryogenic pumps...

New Director General at ESO

Xavier Barcons became the eighth director general of the European Southern Observatory on September 1, succeeding Tim de Zeeuw who had served since 2007. Barcons begins his tenure at an exciting time for ESO, as construction of its Extremely Large Telescope is progressing and it is set to see first...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
