Abstract: A flow directing apparatus for directing fluid flow includes a flow body defining a bore therethrough configured and adapted to direct fluid flowing therethrough. The bore includes an outlet and an opposed inlet with an enlargement, formed as a countersink and/or a chamfer using a suitable boring device. The enlargement is configured and adapted to reduce sensitivity to entrance-edge conditions for the bore.

Abstract: An air cap is configured to be affixed to a nozzle assembly as a downstream facing component of the nozzle assembly. The air cap includes a plurality of air wipe passages with outlets defined in a circumferential direction around a downstream facing surface of the air cap. A nozzle assembly can include an outer wall wherein the air cap is connected to the nozzle assembly outboard of the outer wall. An inner wall can be connected to the outer wall by a plurality of air swirl vanes. One or more fuel circuit components can be connected to the nozzle assembly inboard of the inner wall.

Abstract: A fuel injector for an exhaust heater includes a cover and an air blast nozzle. The cover has a nozzle seat, a fuel inlet, and an air inlet, the nozzle seat arranged along a flow axis. The air blast nozzle is seated in the nozzle seat and has a unibody. The air blast nozzle unibody is in fluid communication with the fuel inlet and the air inlet arranged along the flow axis to port fuel and air into a combustion volume, e.g., to heat a stream of exhaust gas flowing between an engine and a catalytic reactor by combustion with fuel introduced through the fuel inlet and air introduced through the air inlet.
