摘要
本文以IAPWS-IF97为基础,参考有关文献,提出一组水和水蒸汽热力性质计算的简明方程,包括饱和蒸汽压、饱和液密度、饱和汽密度、饱和液焓、饱和汽焓、汽化潜热6个方程,并以IAPW S-IF97的计算结果拟合了方程中的常数。所提出的6个方程,形式简单,使用方便,具有良好的计算精度,完全覆盖石化、炼油企业所用蒸汽参数范围。
Based on IAPWS-IF97,six equations are given out in this paper for evaluating thermodynamic properties of saturated steam and water.The six equations are equations for saturated vapour pressure,saturated liquid density,saturated vapour density,saturated liquid entrolpy,saturated vapour entralpy and latent heat of evapouration.All the equations are accurate with simple forms and therefore easy to use in engineering calculation.
