Fuel nozzle for the reduction of the modal coupling combustion dynamics reduction

摘要

A fuel nozzle has a central body, which is axially over a length extends along an axial center line. A jacket surrounds the central body circumferentially at least over a portion of the length of the central body. A plurality of circumferentially surround the central body at least along a portion of the length of the central body, and each of the fuel openings in the individual turns has a different convective on.
