| 摘 要： | 1997年国际水和水蒸汽协会(IAPWS)提出的工业用水和水蒸汽热力性质模型(IAPWS-IF97),具有适用范围较大、区域划分简洁、计算方程形式简单及精度高等优点,已被广泛接受。但在诸多文献中当由参数h,s求其他参数时,对其相关边界条件却很少提及。通过分析和研究,确定了相关边界条件,由参数h,s编程计算,保证了各区域内的其他参数的准确性。计算结果表明,能够通过所获得的边界条件,根据参数h,s准确地确定所要计算的区域并得出正确的结果,因此为开发各区域水蒸汽热力性质计算程序提供了保障。

| Abstract: | The industrial use of water and steam thermal properties was offered by IAPWS in 1997(IAPWS-IF97),which had been accepted widely.But the relevant boundary conditions was referred little when by h,s calculating other parameters in many literature.In this paper,the relevant boundary conditions is acquired by study and analyzing,and the veracity of other region parameter is assured by h,s programming calculating.The calculation result shows that according to gotten boundary conditions,and by variables(h,s),it can accurately determine the region wanted to calculate and get accurate result.So it offers assurance for the calculation program of various region steam thermal properties. |
