  • Nozzles and methods of mixing fluid flows
    Patent number: 10898912
    Abstract: A nozzle assembly including an inner tube and an outer housing. The inner tube terminates at an outlet end and defines a first flow passage. The first flow passage directs first fluid flow to the outlet end in a primary flow direction. The outer housing includes a tubular side wall and an end wall. The tubular side wall defines a central axis. The end wall defines an exit orifice and an interior guide structure. The outlet end is axially aligned with the exit orifice. A second flow passage is established between the inner tube and the outer housing. The interior guide structure is configured and arranged relative to the outlet end to direct at least a portion of a second fluid flow from the second flow passage toward the outlet end in a direction initially opposite the primary flow direction for generating mixed fluid flow.
