Numerical Modeling of Wet Steam Flow in Steam Turbine Channel [PDF]
, 2012 Dans la pratique des centrales électriques, le travail est extrait de la vapeur en expansion en trois étapes, à savoir les turbines à haute pression(HP), à pression intermédiaire (IP) et à basse pression(LP). Au cours du processus de détente dans la turbine BP, la vapeur se refroidit et, à certains stades, elle nucléate pour devenir un mélange ...

Steam reheater with helical tube bundle for wet steam turbine [PDF]
E3S Web of Conferences, 2020 Since steam heat exchangers, used at steam cycle of Russian nuclear power stations, were designed while the knowledge about the separation and the heat exchange processes was limited, deviations between its empirical and theoretical characteristics occur.

Wet steam flow in 1100 MW turbine [PDF]
Archives of Thermodynamics, 2021 The paper deals with the wet steam flow in a steam turbine operating in a nuclear power plant. Using a pneumatic and an optical probe, the static pressure, steam velocity, steam wetness and the fine water droplets diameter spectra were measured before and beyond the last turbine low-pressure stage.
