Abstract
A mixer for mixing first and second fluids has a passageway along which a stream comprising the first fluid flows along an axis of the passageway. The passageway has, in sequence in the downstream direction, a convergent section, a throat, and a divergent section. An injector introduces the second fluid into the stream in the passageway upstream of the divergent section. A swirl generator in the passageway is upstream of the convergent section.
