摘要
采用VC和Matlab混合编程的方法,编制了CRGT循环中工质(水-水蒸气和空气-湿燃气)的热力性质计算程序。空气和干燃气的热力性质采用理想气体掺混模型,水和蒸汽的热力性质采用IAPWS-IF97标准模型,湿燃气的热力性质采用改进的工程计算方法进行处理。计算结果表明:该方法计算精度高、计算速度快。
The calculation program for the working fluid thermodynamic properties（including water-water steam and air-wet gas） in CRGT was built with the hybrid programming method of MATLAB and VC.Ideal gas mixing model was adopt to simulate air and dry-gas property,IAPWS-IF97 standard model was adopt to calculate water and steam property.The property of wet-gas was calculated by advanced engineering method on the basis of the above models.The result shows that this method has an extremely high calculation speed and accuracy.
