Application of thermoanemometry for investigation of the large water droplets in the vicinity of the LP stage of a full scale steam turbine
Mazur, Oton ; Uruba, Václav ; Šarboch, Jaroslav ; Řehák, Vratislav ; Jonáš, Pavel
The response of a CTA hot-wire anemometer on a water droplet impact is investigated. Characteristic shape of the CTA-output response signal after a jewater jet impact was ascertained. This knowledge was applied to an analysis of time records made in the vicinity of the LP stage of turbine. Statistical estimates of the occurrence and frquency of large droplets in the wet steam flow are presented.
On the spectral analysis of the wet steam flow in the vicinity of the LP stage of a full-scale steam turbine
Uruba, Václav ; Jonáš, Pavel ; Mazur, Oton ; Řehák, Vratislav
The unsteady steam velocity spectral characteristics were qualitatively evaluated for measurements brought upstream and downstream the LP stage. Using the conditional averaging technique the signal has been split up into periodical and random components. significant frequencies in velocity spectra have been detected.
Fázově středované charakteristiky proudění mokré páry po proudu za NT stupněm parní turbíny
Jonáš, Pavel ; Mazur, Oton ; Uruba, Václav
Single rotary inclined hot-wire anemometer was used during the investigation of the phase averaged characteristics of unsteady wet steam flow inside the LP stage of the steam turbine TG21 at the power station Prunéřov II. The effect of the passage from the nominal regime to the reduced one on the flow structure is outlined.
