摘要： A flow directing apparatus for directing fluid flowing therethrough includes a flow body defining an upstream facing inlet surface and an opposed downstream facing outlet surface with a bore defined through the flow body. The bore includes an inlet portion of the bore extending in a downstream direction from an inlet where the bore meets the inlet surface. An intermediate portion of the bore extends in a downstream direction from the inlet portion of the bore. A backstep portion of the bore extends downstream from the intermediate portion of the bore to an outlet where the bore meets the outlet surface. The intermediate portion of the bore has a cross-sectional flow area that is smaller than that of the inlet portion and smaller than that of the backstep portion to provide a backward facing step in flow area for flow through the bore.

摘要： 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.

摘要： A method of issuing a spray cone from a nozzle includes modulating flow to two separate first and second fluid circuits, each connected to a common injection point orifice to vary spray angle on a substantially hollow spray cone over time to create a full spray cone. Modulating can include controlling first and second flow modulators, connected to the first and second fluid circuits, respectively, to coordinate oscillating flow rate modulation of both of the first and second fluid circuits. Controlling can include controlling the oscillating flow rate modulation for the first flow modulator to be out of phase with, to be in antiphase with, to be vertically shifted in magnitude relative to, and/or to have an amplitude that is equal to that of the second flow modulator.
