Abstract

L'invention concerne une turbine à écoulement diphasique disposée sur un moyeu couplé à un arbre rotatif et entraînée par la réception d'un écoulement diphasique comprenant un composant en phase liquide et un composant en phase gazeuse. La pale de rotor selon l'invention comprend : un corps principal de pale de rotor fixé au moyeu et ayant une surface de pression qui reçoit l'écoulement diphasique ; et au moins une section de rainure qui s'étend au-dessus de la surface de pression de façon à croiser la direction radiale de l'arbre rotatif.
