摘　　要：采用以实际混合气体状态方程R-K为基础的湿空气热物性模型(简称R-K模型),用Matlab编译出湿空气工质热物性的计算模型,与采用理想模型的计算模型做分析比较;将湿空气热物性计算模型应用于饱和器工作过程,给定初参数,分别用两种模型计算饱和器出口参数做数据比较。结果表明:在饱和器出口低参数范围,计算结果基本不变。A calculation model for thermophysical properties of wet air working medium was set up with Matlab using the wet air model based on R-K state equation for real gas mixtures（called R-K model）,which was then compared with the calculation model for ideal gas.Both the models were used to calculate the outlet parameters of a saturator with given parameters.Results show that the calculation data of above two models agree well with one another at low parameters.
