Superfluid helium (He II) offers unique challenges and opportunities in heat and mass transfer phenomena due to its exceptional thermal conductivity and peculiar flow characteristics. These properties make superfluid helium an indispensable medium in cooling applications, particularly in high-energy physics where maintaining the operational stability of superconducting cavities is... -

The solubility of hydrogen in liquid helium seems to be unknown. One potential explanation for this could be the exceedingly low solubility limit, making this phenomenon irrelevant for the vast majority of applications. In cryogenics, however, this effect is crucial. Traces of hydrogen in liquid helium and in the liquid helium supply systems result in a malfunction of liquid helium flow...

Liquid oxygen, a potential spacecraft fuel, exhibits distinct behaviors under varying gravitational conditions, particularly at the liquid-vapor interface. While this interface remains static under standard gravity, it shifts significantly in microgravity environments. Accurately predicting this movement is essential for designing spacecraft fuel tanks to ensure uninterrupted fuel supply, a...

ALLEGRO is a proposed FCC-ee general-purpose detector concept with a noble-liquid electromagnetic calorimeter (ECAL) as one of its central detectors. Noble-liquid calorimetry is a strong option for future particle physics experiments – for both, hadron and lepton colliders. Such an ECAL is composed of a sandwich of 1536 multi-layer read-out electrodes realized as PCBs and the same number of...

We present a new way to measure the thermal conductivity and diffusivity of cryogenic fluids using a modification of the 3-omega technique. These modifications include a wire-in-hole geometry that limits natural convection of the fluid around the measurement wire allowing for more accurate measurement. A complete theory of the thermal environment around the measurement wire is presented. This...

Liquefied natural gas (LNG), as a widely available and renewable fuel, can address the growing energy demand and significantly reduce greenhouse gas emissions. In the liquefaction of natural gas, pivotal components such as heat exchangers require reliable methods for predicting heat transfer coefficients. Existing prediction methods are mostly focused on conventional channels with hydraulic...
