    Abstract: A fluid nozzle includes a first fluid circuit, a second fluid circuit spaced apart from the first fluid circuit and a fuel circuit. The fuel circuit is defined between the first and second fluid circuits and between a first fuel circuit wall and a second fuel circuit wall. A ring-shaped permeable barrier is positioned between the first and second fuel circuit walls configured and adapted to provide a controlled resistance to fuel flow. A fuel distributor includes a first fuel circuit wall and a second fuel circuit wall spaced apart from the first fuel circuit wall. A fuel circuit is defined between the first and second fuel circuit walls. A ring-shaped permeable barrier is positioned between first and second fuel circuit walls. A combustion assembly includes a combustor housing, a combustor dome positioned at an upstream end of the combustor housing, and a fluid nozzle positioned adjacent the combustor dome.

    Abstract: An atomizer includes an atomizer body with a plurality of air passages defined therethrough from an upstream end of the atomizer body to a downstream end thereof. The air passages together define an air circuit through the atomizer body. A fuel circuit is defined in the atomizer body extending from a fuel inlet to a respective fuel outlet opening into each air passage. The air passages can be arranged circumferentially about a central axis defined by the atomizer body. The fuel circuit can include a manifold extending circumferentially about the atomizer body in fluid communication with a fuel opening in each respective air passage.

    Abstract: A spray nozzle comprising a housing including a primary passage defining a primary axis, a series of secondary passages configured to provide swirl to a fluid passing therethrough circumferentially positioned around the housing, a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid.

    Abstract: A swirler, such as for swirling air in a fuel injector of a gas turbine engine, includes a swirler body with opposed inlet and outlet ends with a swirler wall extending therebetween along a longitudinal axis. The inlet end of the swirler body defines an inlet opening. A plurality of swirl slots is defined through a portion of the swirler wall that converges toward the longitudinal axis in a direction from the inlet opening toward the outlet end of the swirler body. The swirl slots are radially off-set with respect to the longitudinal axis for imparting swirl on a flow passing from the inlet opening, through the swirl slots, and past the outlet end of the swirler body.

    Abstract: A nozzle for injecting liquid includes a nozzle body defining a flow channel and a swirl ante-chamber in fluid communication with the flow channel. An injection point orifice is defined in the swirl ante-chamber. The flow channel feeds into the swirl ante-chamber to impart a tangential flow component on fluids entering the swirl ante-chamber to generate swirl on a spray issuing from the injection point orifice. A second flow channel can be included in fluid communication with the swirl ante-chamber. The second flow channel feeds into the swirl ante-chamber in cooperation with or in opposition to the first flow channel. The first flow channel, second flow channel, and swirl ante-chamber are configured and adapted to adjust spray angle of a spray issuing from the injection point orifice by varying flow apportionment among the first and second flow channels.

    Abstract: A nozzle includes an outer gas flow path, an inner gas flow path radially inward from the outer gas flow path, a liquid flow path defined radially between the inner gas flow path and the outer air flow path, and a core conduit defined radially inward from the inner gas flow path. An injector assembly includes an outer housing, a nozzle within the outer housing, and an outer housing gas flow path defined radially outward from the nozzle between an inner surface of the outer housing and an outer surface of the nozzle. The nozzle includes an outer gas flow path, an inner gas flow path radially inward from the outer gas flow path, a liquid flow path defined radially between the inner gas flow path and the outer gas flow path and a core conduit defined radially inward from the inner gas flow path.
