Wet steam is high quality steam which results when the thermodynamic conditions fall below the saturation line. Wet steam thus involves some liquid water entrained with the steam. AFT Arrow is designed to handle only superheated steam and gasses.
Technically AFT Arrow cannot model wet steam. However, common industry practice holds that wet steam above 90% quality behaves substantially the same as superheated steam when calculating pipe flow. With this caveat, AFT Arrow can model wet steam although some loss of accuracy will likely occur.
