How the SpaceX Explosion Would Have Been Different in Florida

Shortly after SpaceX’s massive Starship launched from Texas on its first full test early Thursday, the 400-foot stack of hardware began to tumble until it broke apart in a fiery explosion over the Gulf of Mexico. The overall demonstration mission – a test of the new rocket’s ability to ignite and clear the pad’s 500-foot tower...

Svanehøj Acquires Complete Cryogenic Services

With its third company acquisition in just over two years, marine pump specialist, Svanehøj, continues to expand its service solution business, this time by taking over California-based Complete Cryogenic Services (CCS), a specialist in service and overhaul of submerged pumps on LNG tankers. The number of LNG tankers globally has grown...

Skyroot Aerospace and Dhawan-II’s More Powerful 3D-Printed Cryogenic Engine

In 2020, the world was introduced to Dhawan-I, a 3D printed cryogenic engine made by Skyroot Aerospace. Three years later, the Indian company has been working on a more powerful model, unveiling to the public the new and improved Dhawan-II, which is said to have successfully completed testing. Like its predecessor,...

A Game Changer for CERN

CERN’s new visitor and education center, Science Gateway, due to open this autumn, will welcome up to half a million people each year. Project leader Patrick Geeraert describes how this iconic project came about, how it will operate, and what it aims to achieve. How did the idea for Science...

New SLAC-Stanford Battery Center Targets Energy Transition

The Department of Energy’s SLAC National Accelerator Laboratory and Stanford University announced the launch of a new joint battery center at SLAC. It will bring together the resources and expertise of the national lab, the university and Silicon Valley to accelerate the deployment of batteries and other energy storage solutions...

New Study Could Help Pinpoint Hidden Helium Gas Fields

Research led by the University of Oxford could help overturn the current supply crisis of helium, a vital societal resource. The study proposes a new model to account for the existence of previously unexplained helium-rich reservoirs. The findings, published in Nature, could help locate untapped reservoirs of accessible helium. Dr. Anran...

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
