1. A turbine engine comprising:
a compressor section, combustor section, and turbine section in serial flow arrangement, with the combustor section including a fuel nozzle assembly comprising:
a fuel nozzle, defining a longitudinal axis and a fuel passage, and terminating at a nozzle tip, and exhausting to the combustor section at the nozzle tip extending through the longitudinal axis;
a swirler, defining a swirler passage about the fuel nozzle, having a forward wall spaced from an aft wall, and having a center wall positioned between the forward wall and the aft wall;
a set of vanes provided within the swirler, the set of vanes including a first set of vanes extending between the forward wall and the center wall, and the set of vanes including a second set of vanes extending between the center wall and the aft wall; and
a lip extending from the center wall in a downstream direction relative to a flow of air through the swirler, the lip terminating at an aft end;
wherein the nozzle tip is positioned aft of the aft end of the lip relative to the longitudinal axis, and;
wherein the aft end of the lip is positioned forward of the aft wall relative to the longitudinal axis.
