Abstract
A fuel nozzle for a gas turbine engine includes a first fuel nozzle body and a second fuel nozzle body. The first fuel nozzle body and the second fuel nozzle body form a fuel passage. The fuel passage includes a fuel accumulation chamber, an upstream fuel passage, a downstream fuel passage, and a plurality of tangential feed holes. The upstream fuel passage extends along an upstream fuel passage centerline to a terminal end of the upstream fuel passage. The terminal end is spaced from the accumulation chamber. The downstream fuel passage extends from a passage inlet along a downstream fuel passage centerline. The passage inlet is disposed at the accumulation chamber. The plurality of tangential feed holes are formed by the first fuel nozzle body. Each tangential feed hole of the plurality of tangential feed holes extends between and to a hole inlet and a hole outlet. The hole inlet is disposed at the upstream fuel passage upstream of the terminal end. The hole outlet is disposed at the accumulation chamber.
