Abstract: This disclosure provides an improved nozzle assembly. The nozzle assembly includes a spray element for jetting media through an outlet (e.g. onto a surface), an active conduit for supplying a first media to the spray element, and a passive conduit for supplying a feed of a second media to the spray element. The spray element includes an eductor that is actively fed with a pressurized stream of the first media (i.e., motive fluid) via an annular injection port coupled to the active conduit, and passively fed by the second media via an intake duct disposed cen-trally within the injection port. The eductor utilizes the Venturi effect to efficiently prepare a homogenized media jet from the two different media feeds. A system comprising the nozzle assembly, and methods of using each of the same, are also disclosed.
