Abstract

Esta rueda comprende una pluralidad de álabes (2) dispuestos en una corona (3) y está equipada con un miembro que forma punta (10) unido a una región central (32) de la corona o cubo de la rueda (1) radialmente dentro de los álabes (2), la corona define una superficie mojada (31) para guiar un flujo (E) que pasa entre los álabes. El miembro que forma punta (10) está provisto con al menos una abertura (121) para desviar una fracción (E1) del flujo hacia el volumen interno (V10) y es capaz de modificar la trayectoria de la fracción de flujo (E1) que entra en este volumen a través de la abertura (121) Esta aleta (15) se extiende desde el borde (112) de la falda (11) que define una abertura de salida (14) del miembro (10) para la fracción de flujo (E1).
