Abstract: Apparati for generating a mist are disclosed. One apparatus is disclosed, which has an elongate hollow body (12) and an elongate member (14) located within the body (12). A transport fluid passage (16) and a nozzle (32) are defined between the body (12) and the elongate member (14). The transport fluid passage (16) has a throat portion of reduced cross-sectional area and is in fluid communication with the nozzle (32). The elongate member (14) includes a working fluid passage (26) and one or more communicating openings, such as for example, bores, annuli, and combinations thereof, (30) extending radially outward from the working fluid passage (26).
