Abstract

La invención se refiere a una paleta guía (1) para la rueda guía de una bomba o turbina, que comprende un cuerpo de paleta guía. El cuerpo de la paleta guía tiene dos caras extremas (2), un borde de ataque (3), un borde de salida (4), una primera cara lateral de guía de flujo (5) y una segunda cara lateral de guía de flujo (5), que conectan el borde de ataque (3) y el borde de salida (4), y que forman diferentes perfiles de flujo (12) a lo largo de un eje. Dichos perfiles de flujo tienen cada uno una cuerda (8), una línea de curvatura media (9) y un ángulo final de curvatura media (α) entre la línea de curvatura media (9) y la cuerda (8) en el borde de salida (4) de la paleta guía. La paleta guía (1) puede montarse de forma giratoria alrededor de un eje de rotación (7), que, más concretamente, está definido por dos pasadores de pivote (11). El objetivo de la invención es minimizar las pérdidas en un sistema hidroeléctrico y lograr una alta eficiencia. Para lograr este objetivo, el álabe guía (1) tiene, a lo largo de su eje, al menos un perfil de flujo (12) con un ángulo final de curva de curvatura media positivo (α) y al menos un perfil de flujo (12) con un ángulo final de curva de curvatura media negativo (α). La invención también se refiere a un método para diseñar un sistema hidroeléctrico, más particularmente una bomba o turbina, que comprende una rueda guía con álabes guía (1), más particularmente una turbina Kaplan o una turbina Francis, en la que, mediante la variación de los parámetros de diseño, se forman diferentes variantes y se determinan las condiciones de flujo que se pueden lograr implementando las variantes individuales, más particularmente mediante una simulación de flujo o mediante pruebas, tras lo cual, de acuerdo con las condiciones de flujo que se pueden lograr, se selecciona una de las variantes, más particularmente la variante para la que se logra una eficiencia óptima.
