Abstract
Based upon the conceptual design reports for the future circular collider (FCC) cryogenic system, the need for more accurate thermodynamic property models of mixtures was identified. Both academic institutes and world-wide industries have identified the lack of a reliable equation of state for mixtures used at very low temperatures. Detailed cryogenic architecture modeling and design cannot be assessed without valid fluid properties. Therefore, the latter is the focus of this work. The modeling was extended to other fluids beneficial for scientific and industrial application beyond the particle physic's needs. The properties are modeled for some noble gas mixtures with the use of multi-fluid Helmholtz-energy-explicit models: helium-neon, neon-argon, and helium-argon.Citation
