Design and calculation of humid air turbine cycle need saturated humidity and e nthalpy of humid air at 423K

5MPa. However

the models proposed by previous workers are available only up to 373K

5MPa. In this paper

a method based on Helgeson Model is proposed.The saturated composition o f N 2-H 2O system at 336.15-636.35K

1.74-25.6MP a and O 2-H 2O system at 373-533K

0.99-5.77MPa are predicted. The deviations from the experimental data are less than 5%. The predictions for humid air at 273-372℃

0.1MPa are comparable with the results using the Hyland and Wexler model. The saturated composition and enthalpy of humid air at 473-573K

5-15MPa

are also presented
