Students Design Experimental Fuel System To Power Liquid-Propellant Rocket Engines

Aerospace Engineering students Alex Clay and Samir Ahmed have spent the past four years at Embry-Riddle Aeronautical University manufacturing complex liquid-propellant rocket engines. Now, as they near graduation, there is one last thing they’d like to do: Prepare for ignition. Along with fellow members of the university’s Experimental Rocket Propulsion Laboratory...

BCCK Boosts Propane Recovery with Next-Generation Technology at Cryogenic Gas Processing Facility

BCCK, a leader in engineering, procurement, fabrication and field construction services, has applied patent-pending technology, G2R-Flex®, to provide enhanced propane recovery for a premier midstream group in Ohio’s Marcellus-Utica Basin. Utilizing a skidded BCCK patent-pending design, G2R-Flex® improved current 200 MMSCFD GSP facilities’ propane recoveries to greater than 99 percent in...

GENH2 Partners with H2 Genesis to Provide Small-Scale Hydrogen Liquefaction

GenH2, an industry leader in hydrogen infrastructure solutions, announced that the company has signed a partnership agreement with H2 Genesis, a leading liquid hydrogen infrastructure and operations company, to deliver liquid hydrogen across North America. In their first collaboration, GenH2, as manufacturer, and H2 Genesis, as owner-operator, will deploy the...

First Measurements of Hydrogen-Boron Fusion in a Magnetically Confined Fusion Plasma

As fusion developers around the world race to commercialize fusion energy, TAE Technologies has pioneered the pursuit of the cleanest and most economical path to providing electricity with hydrogen-boron (also known as p-B11 or p11B), an abundant, environmentally sound fuel. Recently, the company announced, in collaboration with Japan’s National Institute...

Chase Coolers and Their Long History in CMB Science

Making advances in science requires the proper tools. Often those tools must be developed by scientists themselves. That’s the story of most science missions studying Cosmic Microwave Background radiation (CMB). Sub-Kelvin coolers developed by Chase Research Cryogenics (CSA CSM) have played a strategic role in many of these missions. Let’s...

Launching a Groundbreaking Mobile Liquid Hydrogen System

GenH2, an industry leader in hydrogen infrastructure solutions, announced the launch of its groundbreaking LS20 mobile liquid hydrogen system, an end-to-end liquefaction and storage system. The innovative, mobile liquefaction unit offers a space-optimized, fully integrated liquid hydrogen solution to be used in a range of applications from transportation to energy...

Two-Phase Flows

Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...

Supercritical Fluids

A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...

Brayton Cycle

The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

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...
