Abstract

Para reducir el desgaste de un propulsor (120, 130) debido a gotitas de líquido en un flujo de gas entrante, el propulsor (120, 130) comprende cuellos de botella convergentes y divergentes; el flujo entrante pasa a través de los cuellos de botella de manera que la velocidad del gas en la toma (122) del propulsor primero aumenta de manera repentina y sustancial y después disminuye de manera repentina y sustancial; además, el propulsor está configurado para que, internamente después de su toma, el flujo entrante se desvíe de manera gradual en el plano meridional.
