摘要

本研究提出了 H2 + Ar、H2 + He 和 H2 + Ne 二元混合物的新状态方程。这些方程是根据还原亥姆霍兹能制定的，可以计算整个流体表面的所有热力学性质，包括气相、液相、超临界区和平衡态。这些模型通过与实验数据的比较得到了验证，并对其物理行为进行了分析。此外，还将新的状态方程与文献中其他最先进的模型进行了比较。

New fundamental equations of state for binary hydrogen mixtures containing argon, helium, and neon

In this work, new equations of state for the binary mixtures H₂ + Ar, H₂ + He, and H₂ + Ne are presented. The equations are formulated in terms of the reduced Helmholtz energy and allow for the calculation of all thermodynamic properties over the entire fluid surface including the gas phase, liquid phase, supercritical region, and equilibrium states. The models are validated by comparisons with experimental data and their physical behavior is analyzed. Furthermore, the new equations of state are compared to other state-of-the-art models from the literature.
