Abstract:
1. An apparatus for generating a mist comprising: a housing having a plurality of interior walls, at least one of the plurality of interior walls defining a passageway along a longitudinal center axis, the passageway having a transport fluid inlet, a plenum adjacent to the transport fluid inlet, and a portion adjacent to the plenum, and an outlet, the at least one of the plurality of interior walls being continuously tapered outwardly with respect to the axis along the portion and the plenum adjacent to the transport fluid inlet being of different cross-sectional area than the transport fluid inlet at every point along a length of the plenum adjacent to the transport fluid inlet; a protrusion with a solid interior located proximate the portion, the protrusion having an outer surface tapered outwardly with respect to the axis; a means for generating a mist substantially of a desired droplet size from a working fluid with a transport fluid, the means including a transport nozzle and a working nozzle, the transport nozzle being defined between the at least one of the plurality of interior walls tapered outwardly with respect to the axis along the portion, and the outer surface tapered outwardly of the protrusion; the working nozzle being defined by other of the plurality of interior walls of the housing, the working nozzle being coincident the transport nozzle so that the working fluid communicated to and exiting the working nozzle and the transport fluid exiting the transport nozzle contact for the first time and mix downstream of an outlet of each of the respective working nozzle and transport nozzle and within the housing; wherein the working nozzle is defined by a working nozzle outer surface facing inward toward the axis and the working nozzle inner surface facing outward away from the axis; wherein at least part of the working nozzle outer surface converges toward the axis at the outlet of the working nozzle in a direction along the axis toward the outlet; and a working fluid inlet disposed along the housing in communication with the working nozzle.
