Numerical Modeling of Wet Steam Flow in Steam Turbine Channel [PDF]
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 ...
