摘要
建立了一个用以计算极性流体热力学性质的微扰理论模型。模型中考虑了粒子间硬球排斥、色散、静电和诱导等相互作用能,由同时拟合饱和蒸汽压和液相密度获得分子微观参数。对几种常见的极性流体的计算结果表明,这一模型具有比较简单、准确、参数的物理意义明确等优点。
perturbation model is developed for calculation of thermodynamic properties ofthe polar fluids. The hard sphere repulsive force, dispersion, induction and electrostaticinteractions are taken into account. The molecular parameters are obtained by fitting theexperimental vapor pressure and liquid density data simultaneously. The calculated resultsfor eight polar fluids show that our model is rather simple and accurate, and the parametersin this model are defined with physical significance.
