Abstract

Alabe móvil de turbina. Si el ángulo que define una tangente a la parte de la superficie dorsal en el borde delantero del álabe móvil con una recta perpendicular al árbol giratorio de la turbina se designa con {ze} y el ángulo de salida geométrica del álabe fijo se designa con {al}{sub,N}, {ze} cumple la relación: {al}{sub,N}+2º<{ze}<{al}{sub,N}+12º. Como resultado de ello, la forma de la parte de la superficie dorsal, en el borde delantero y en una parte contigua al mismo, del álabe móvil no es paralela a la estela del álabe fijo. Aplicable para que el álabe móvil contribuya a aumentar el rendimiento de la turbina, al tiempo que a suprimir un brusco aumento irregular de la velocidad de flujo.
