Numerical Simulations of Large-Amplitude Acoustic Oscillations in Cryogenic Hydrogen at Pipe Exit

Hydrogen
Pipe exits into cryogenic systems, such as an exit of a venting or sensor tube inside a cryogenic storage tank, can affect spontaneously occurring acoustic oscillations, known as Taconis oscillations.

Assessing the Feasibility of Removing Graffiti from Railway Vehicles Using Ultra-Freezing Air Projection

Applied Sciences
Unauthorised graffiti is a challenge in urban environments, affecting railway structures, stations, tracks, and vehicles. Inefficient cleaning methods increase the costs and downtime of railcars, limiting passenger transport. In turn, they are harmful to

Thermal Conductivity of Thermally-Isolating Polymeric and Composite Structural Support Materials Between 0.3 and 4 K

, 2008
We present measurements of the low-temperature thermal conductivity of a number of polymeric and composite materials from 0.3 to 4 K. The materials measured are Vespel SP-1, Vespel SP-22, unfilled PEEK, 30% carbon fiber-filled PEEK, 30% glass-filled PEEK,

Dynamic Analysis and Experimental Verification of a Multi-Degree-of-Freedom Eddy Current Damper in a Cryogenic Environment

IEEE Access
Reusable rockets are under development and have received considerable attention. The large rockets and reusable vehicles under development in Japan use liquid hydrogen, and their turbopumps require high-speed rotation.

Research on loss differences and thermal optimisation of submerged cryogenic high‐speed permanent magnet motors

IET Electric Power Applications
The utilisation of high‐speed motors in cryogenic motors achieves high efficiency and rapid transmission of cryogenic media, and at the same time, the high loss characteristic of high‐speed motors enhances the vaporisation rate of cryogenic media and ...

Superfluid Helium Flow in Porous Media [PDF]

, 2013
Superfluid helium is primarily used in the field of applied superconductivity. Given the complexity of the magnet geometry and the scales involved, a real 3D simulation of heat transfer in such devices at the micro-channel scale is very difficult, even ...
