基于IAPWS-IF97的水和水蒸气性质计算模型及实现

Calculation of Water and Steam Properties Based on IAPWS-IF97

将国际水和水蒸气性质协会(IAPWS)提供的1997 年工业用计算模型(简称IAPWS-IF97)和国际公式化委员会提供的1967年工业用计算模型(简称IFC67)的不同方面做了比较分析,最后结合工程实践,在确保计算结果精确、计算速度快的基础上补充了计算炯的函数,并根据IAPWS- IF97模型编制了基于构件技术的水和水蒸气性质计算软件。

The new calculating models with the international association for the properties of water and steam used for industrial formulation (IAPWS-IF97) is introduced. The differences between IAPWS-IF97 and IFC67 are discussed. The calculation software for the thermodynamic properties of water and steam based on the IAPWS-IF97 formulation is presented .
