The helium cools the fuel and transports the heat first to the turbines driving the compressor(s) and next to the power turbine of the gas turbine. Logically this must be a closed-cycle helium gas turbine. Remarkable features of such gas turbines are: 1. helium is a one atomic gas, so sealing of rotating shafts is very complicated. 2.

HELIAL helium liquefiers | Air Liquide Advanced Technologies

The HELIAL range of standard helium liquefiers has a refrigeration capacity of 4.5 K. To reach that temperature, the HELIAL refrigerator uses helium, the gas that is the coldest in its liquid state. Refrigeration is vital for testing satellites in conditions of interstellar vacuum.

Abstract The cooling and heating of palladium clusters Pd 13 and Pd 55 by binary collisions with atoms of a surrounding helium gas are studied by means of molecular dynamics simulation. The efficiency of the collisional energy transfer is determined as a function of cluster and gas temperature and of cluster phase, the cluster being in either a solid or a liquid phase.

Helium gas, which is significantly lighter than argon and nitrogen, was successfully implemented in the L-PBF process of Ti-6Al-4V. Helium and argon-helium gas mixtures enable a reduction in the porosity upon higher build rates. This is attributed to the positive balance of density and thermal properties offered by these mixtures.
