Abstract

Un difusor aerodinámico para un compresor centrífugo formado por un área de pasaje de difusor y una pluralidad de cuchillas de difusor ubicadas dentro del área de pasaje del difusor. El área de pasaje de difusor es definida entre un plato concentrador y una cubierta del compresor centrífugo. Cada una de las cuchillas de difusor tienen una configuración torcida en una dirección de sujeción tomada entre el plato de concentración y una porción exterior y la cubierta ubicada en el lado opuesto del plato concentrador. Como resultado de la configuración torcida, el ángulo de la cuchilla de entrada de cuchilla de difusor disminuye desde el plato concentrador a la porción exterior de la cubierta y las medidas de solidez en los bordes limitantes de los platos de difusor varían entre una baja solidez medida en el plato concentrador de menos de 1.0 y un alto valor de solidez medido en la porción exterior de la cubierta de no menos de 1.0.
