Patent ID: 8701419

Claim:
A method, comprising: receiving air into a plurality of tubes extending through a body of a multi-tube fuel nozzle, wherein each tube of the plurality of tubes intakes the air through an aperture of a plurality of apertures having at least one mix-inducing feature that extends crosswise to the aperture at an upstream axial end of the respective tube, wherein the plurality of apertures associated with the plurality of tubes are disposed on at least one inlet plate disposed in contact with the plurality of tubes, wherein a first tube of the plurality of tubes has a first aperture with a first mix-inducing feature comprising a first size and a first shape, wherein a second tube of the plurality of tubes has a second aperture with a second mix-inducing feature comprising a second size and a second shape, wherein the first and second mix-inducing features are geometrically different from one another in that the first size is different than the second size, or the first shape is different than the second shape, or any combination thereof; receiving fuel into each tube of the plurality of tubes at a downstream position from the upstream axial end of the tube; and outputting a fuel-air mixture from the plurality of tubes.
