1. A combustion section for a turbine engine comprising a compression section, the combustion section, and a turbine section in serial flow arrangement, the combustion section comprising:
a dome wall and a combustor liner collectively forming at least a portion of a combustion chamber; and
a fuel nozzle assembly, fluidly coupled to the combustion chamber, and comprising:
a compressed air tube having a compressed air outlet exhausting into the combustion chamber thereby supplying a flow of compressed air to the combustion chamber, the compressed air tube defining a tube centerline axis;
a body defining a gaseous fuel channel exhausting into the combustion chamber at a set of gaseous fuel orifices thereby supplying a flow of gaseous fuel to the combustion chamber, the set of gaseous fuel orifices surrounding at least a portion of the compressed air outlet; and
a set of vortex generators located within the compressed air tube, the set of vortex generators configured to direct the flow of compressed air such that at least a portion of the flow of compressed air forms a set of vortices used to capture the flow of gaseous fuel from the set of gaseous fuel orifices to define a mixture of compressed air and gaseous fuel within the combustion chamber.
