摘要
运用PT系列状态方程,预测氮、氩、二氧化碳和甲烷等流体的转换温度和转换曲线,系列状态方程给出了转换曲线低温分支的良好预测,并与文献转换曲线有较好的相吻合。通过状态方程计算了上述几种流体最大转换温度和最大转换压强。从几种流体的转换曲线来看,方程在预测最大转换压强普遍略大于文献值,最大转换温度则略小于文献值,总体而言方程在一定程度上能较好描述流体转换曲线的性质。
The PT series equations of state[1]were used to predict the transition temperature and transition curve of nitrogen,argon, carbon dioxide and methane.The PT series equations of state gave a good prediction of the low-temperature branch of the transition curve, which was in good agreement with the transition curve in literature.The maximum transition temperature and pressure of the above fluids were calculated by the equation of state.From the conversion curves of several fluids, the maximum conversion pressure predicted by the equation is generally slightly higher than the literature value, and the maximum conversion temperature is slightly lower than the literature value.In general, the equation can describe the properties of the fluid conversion curve better to some extent.
