Abstract
Embodiments of the disclosure relate to a tip for a fuel nozzle. The tip includes a tip body having a first end and a second end spatially disposed from the first end along a longitudinal axis of the tip body. A nozzle passage is disposed at the first end. An entrance cavity, a swirl chamber, and a plurality of swirl passages are disposed within the tip body. The plurality of swirl passages connects the entrance cavity and the swirl chamber. Each of the swirl passages has an opening to the entrance cavity and an exit into the swirl chamber. Fluid communication is provided from the second end to the first end such that fluid flows from the entrance cavity, through the swirl passages, into the swirl chamber, and out through nozzle passage.
Claims19
A tip for a fuel nozzle, comprising:
- a tip body having a first end and a second end, the second end spatially disposed from the first end along a longitudinal axis of the tip body;
- a nozzle passage disposed at the first end
- an entrance cavity disposed within the tip body;
- a swirl chamber disposed within the tip body;
- a plurality of swirl passages disposed within the tip body, the plurality of swirl passages connecting the entrance cavity and the swirl chamber, each of the swirl passages having an opening to the entrance cavity and an exit into the swirl chamber;
- wherein fluid communication is provided from the second end to the first end such that fluid is configured to flow from the entrance cavity, through the swirl passages, into the swirl chamber, and out through nozzle passage;
- and
- wherein each swirl passage winds at least partially around the longitudinal axis from each respective opening to each respective exit and wherein each swirl passage imparts a flow component tangential to the swirl chamber to at least a portion of the fluid flowing through the swirl passage.
