Abstract:
1. An apparatus for generating a mist comprising: (a) a first transport fluid passage disposed around a longitudinal axis and having a first transport fluid inlet, a first transport fluid outlet, and a converging throat portion intermediate the first transport fluid inlet and the first transport fluid outlet, the throat portion having a cross sectional area which is less than that of either the first transport fluid inlet or the first transport fluid outlet; (b) at least one working fluid passage disposed around the longitudinal axis, located radially outwardly, from the longitudinal axis, and circumscribing the first transport fluid passage, and having a working fluid inlet and a working fluid outlet; (c) at least one second transport fluid passage disposed around the longitudinal axis and having a second transport fluid inlet and a second transport fluid outlet in fluid communication with the working fluid passage; and (d) an outlet nozzle in fluid communication with the first transport fluid and working fluid outlets, wherein the second transport fluid outlet being located in the working fluid passage upstream of the working fluid outlet so that a transport fluid in the second transport fluid passage partially atomises a working fluid within the working fluid passage to create a partially atomised working fluid, the partially atomised working fluid exiting the working fluid outlet and entering the first transport fluid passage such that the partially atomised working fluid is further atomised by a flow of transport fluid in the first transport fluid passage prior to the flow of transport fluid in the first transport fluid passage exiting the outlet nozzle.
