Abstract (en)
An ejector (200) has: a motive flow inlet (40); a secondary flow inlet (42); an outlet (44); and a motive nozzle (200). The motive nozzle has an exit (110). A motive flow flowpath proceeds through the motive nozzle and joins a secondary flow flowpath extending from the secondary flow inlet to form a combined flowpath to the outlet. From upstream to downstream along the motive flow flowpath, the motive nozzle has: a convergent section (206); a throat (208); a first divergent section (210) commencing within 10% of a throat-to-exit length (200) and diverging over a first length (L D1 )of at least 10% of the throat-to-exit length (L TE ); a second divergent section (212), the second divergent section diverging over a second length (L D2 ) of at least 10% of the throat-to-exit length at a shallower angle than the first divergent section over said first length.
