摘要
Abstract
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
