水和水蒸气性质通用计算软件的算法研究

Algorithm Research of a General Calculation Software of Water and Water Steam Properties

对国际水和水蒸气性质协会提供的 1997年工业用计算模型 (简称IAPWS -IF97)与国际公式化委员会提供的196 7年工业用计算模型 (简称IFC6 7)进行了比较 ,结合工程应用 ,探讨了在水和水蒸气性质通用计算软件中实现迭代分类、迭代加速以及迭代收敛性和稳定性等方面的问题 。

calculation model for industrial use (IAPWS IF97) provided by the International Water and Steam Properties Association is compared with the 1967 calculation model for industrial use (IFC67) provided by the International Formulation Committee. In connection with engineering applications discussed was the realization in the water and water steam properties general calculation software of such a variety of items as iterative classification, iterative acceleration as well as iterative convergence and stability, etc. Satisfactory calculation results were eventually obtained.
