Measurement of dispersivity and moisture content in experimental turbines by optical methods

Feldberg L. A., Semenov V. N., Popov S. A.

Transactions of the Institute of Fluid-Flow Machinery

2003

nr 113

137--146

The issue of using optical methods for measurements of moisture drops sizing and their concentration in a zone of steam flow condensation are set forth in this paper. A practical applications of optical indicatrice, spectral transparency, and "narrow angles" methods are shown. Main principles of probe construction to investigate two-phase medium are outlined. Practical results of investigations performed on experimental stands and a full-scale turbine are given.

Formation of moisture and corrosive-aggressive media in turbines at different chemistry conditions

Povarov O. A., Semenov V. N., Troitsky A. N.

Transactions of the Institute of Fluid-Flow Machinery

2003

nr 114

67-76

The following paper presents the results of experimental investigations of moisture and corrosion-aggressive liquid film formation in the settings of turbines, working in the zone of steam phase transition.
