Patent ID: 8789769

Claim:
An apparatus for generating a mist comprising: a) an elongate hollow body; and b) an elongate member located within the body such that a first transport fluid passage and a nozzle are defined between the body and the elongate member, the first transport fluid passage having a convergent-divergent internal geometry that forms a throat section and being in fluid communication with the nozzle, wherein the elongate member includes: (i) a working fluid passage; (ii) one or more first communicating openings positioned down-stream of the throat section and extending radially outwardly from the working fluid passage, the first communicating openings allowing fluid communication between the working fluid passage and the first transport fluid passage; and (iii) one or more second communicating openings positioned down stream of the throat section and extending radially outward a second transport fluid passage, the second communicating, openings allowing fluid communication between the working fluid passage and the second transport fluid passage within the second communication openings, wherein the first and second communicating openings are substantially perpendicular to the second and first transport fluid passages, respectively; and (iv) a third transport fluid passage adapted to supply transport fluid into the second transport fluid passage adjacent the first and second communicating openings, wherein the second and third transport fluid passages adjacent the first communicating openings have a convergent-divergent geometry.
