Part of the Advances in Cryogenic Engineering book series (ACRE, volume 39)


The analytical perturbed hard-sphere equation of state (EOS), recently developed from the square-well-linear-extension potential function, has been simplified. The resulting EOS is cubic in terms of volume while retaining the structure of the original equation. It was successfully applied to the prediction of thermodynamic properties of the molecular model fluids (square-well and Lennard-Jones), and saturated properties for seven cryogenic fluids (methane, argon, nitrogen, neon, oxygen, krypton and xenon).
