摘要
基于LabVIEW开发平台,以水和水蒸汽计算模型(IAPWS-IF97)为基础,按照模块化的编程思想,将水和水蒸汽各个区域方程编写为子程序,利用LabVIEW主程序对子程序的调用实现水和水蒸汽热力性质的计算,通过与IAPWS-IF97发布的算例进行对比,结果表明该算法程序计算结果与算例结果吻合良好,可以满足实际工程应用精度要求。
In order to acqurie the thermodynamic property of water and steam,the calculation model for water and steam（IAPWS-IF 97） has been developed according to the idea of modularization programming based on LabVIEW development platform, which is achieved by calling sub VI of the water and steam regions equation through the LabVIEW main program. To verify the rationality of the algorithm, comparing with the published IAPWS-IF 97 numerical example,it shows that the calculation results with this algorithm program are in good agreement with those obtained in the IAPWS-IF 97 cases,which also can satisfy the precision requirement in engineering project.
