Abstract
(EN)
An ejector (200; 300; 400; 600) has a primary inlet (40), a secondary inlet (42), and an outlet (44). A primary flowpath extends from the primary inlet to the outlet. A secondary flowpath extends from the secondary inlet to the outlet. A mixer convergent section (114) is downstream of the secondary inlet. A motive nozzle (100) surrounds the primary flowpath upstream of a junction with the secondary flowpath. The motive nozzle has an exit (110). The mixer has a downstream divergent section downstream of the convergent section and having a divergence half angle of 0.1-2.0 over a first span of at least 3.0 times a minimum diameter of the mixer.
(FR)
L'invention porte sur les éjecteurs. Selon l'invention, un éjecteur (200 ; 300 ; 400 ; 600) présente une entrée principale (40), une entrée secondaire (42) et une sortie (44). Un trajet d'écoulement principal s'étend de l'entrée principale à la sortie. Un trajet d'écoulement secondaire s'étend de l'entrée secondaire à la sortie. Une section convergente de mélangeur (114) est située en aval de l'entrée secondaire. Une tuyère d'entraînement (100) entoure le trajet d'écoulement principal en amont de sa jonction avec le trajet d'écoulement secondaire. La tuyère d'entraînement possède une sortie (110). Le mélangeur comprend une section divergente aval, située en aval de la section convergente, et qui possède un demi-angle de divergences de 0,1 à 2,0 sur une première distance d'au moins 3,0 fois le diamètre minimum du mélangeur.
