Abstract:
1. A method of assembling an ejector, said method comprising: providing a motive nozzle tip having a centerline axis and including a slotted nozzle tip edge having at least one protrusion extending through a plane substantially normal to the centerline axis, the motive nozzle tip includes a frusto-conical portion that is downstream from a tapered conical portion, and wherein the frusto-conical portion tapers at a first angle with respect to the centerline axis and the tapered conical portion tapers at a second angle with respect to the centerline axis, wherein the first angle is different than the second angle; and configuring the motive nozzle tip to produce lobed-shaped vortices in a stream discharged therefrom; and coupling the motive nozzle tip to the ejector, such that the motive nozzle tip is positioned within an ejector casing that includes a low-pressure chamber and an annular mixing channel defined therein, wherein the annular mixing channel is downstream from the low-pressure chamber.
