The mixing rule and the variational perturbation theory together with van der Waals one-fluid model have been used to study the equation of state of the dense fluid He+H2 mixtures with different H2∶He compositions in this work. The first-order quantum correction is included. To test the model and computational code, the isotherm of the fluid He+H2 mixtures at 300 K is calculated by using the existing α-exp-6 optimization potential parameters. The calculated isotherm for the fluid He+H2 mixtures is in agreement with the experimental data and molecular dynamics simulations. Then the equation of state of the fluid He+H2 mixtures with different He∶H2 (He∶H2=1∶1, 1∶3, 3∶1) compositions have been further investigated in the pressure range 0~60 GPa and temperature in the range 50~7000 K. Comparisons of the present results with Monte-Carlo simulations indicate that the quantum corrections for the calculation of the thermodynamic properties become significant at lower temperatures.

选择高密度流体He+H2混合物作为研究对象,用Ree混合规则和van der Waals单组分流体变分微扰理论加量子力学一级修正模型编制计算程序。作为对计算模型及其程序的检验,首先用已有的α-exp-6优化势参数,计算了T=300 K的He+H2混合物的等温相平衡线,得到了与实验值和分子动力学(MD)数值模拟一致的结果,然后进一步计算了0~60 GPa和50~7000 K压力温度范围内的流体He+H2混合物(He∶H2分别为1∶1、1∶3、3∶1摩尔比)的高压物态方程。与Monte-Carlo模拟数据所进行的比较表明,在低温下,量子力学修正对热力学量的计算是重要的。

选择高密度流体He+H2混合物作为研究对象,用Ree混合规则和van der Waals单组分流体变分微扰理论加量子力学一级修正模型编制计算程序。作为对计算模型及其程序的检验,首先用已有的α-exp-6优化势参数,计算了T=300 K的He+H2混合物的等温相平衡线,得到了与实验值和分子动力学(MD)数值模拟一致的结果,然后进一步计算了0~60 GPa和50~7000 K压力温度范围内的流体He+H2混合物(He∶H2分别为1∶1、1∶3、3∶1摩尔比)的高压物态方程。与Monte-Carlo模拟数据所进行的比较表明,在低温下,量子力学修正对热力学量的计算是重要的。

The mixing rule and the variational perturbation theory together with van der Waals one-fluid model have been used to study the equation of state of the dense fluid He+H2 mixtures with different H2∶He compositions in this work. The first-order quantum correction is included. To test the model and computational code, the isotherm of the fluid He+H2 mixtures at 300 K is calculated by using the existing α-exp-6 optimization potential parameters. The calculated isotherm for the fluid He+H2 mixtures is in agreement with the experimental data and molecular dynamics simulations. Then the equation of state of the fluid He+H2 mixtures with different He∶H2 (He∶H2=1∶1, 1∶3, 3∶1) compositions have been further investigated in the pressure range 0~60 GPa and temperature in the range 50~7000 K. Comparisons of the present results with Monte-Carlo simulations indicate that the quantum corrections for the calculation of the thermodynamic properties become significant at lower temperatures.
