| description | An exhaust nozzle for a gas turbine engine. The exhaust nozzle includes a nozzle body having an upstream end axially spaced from a downstream end relative to an axial centerline of the nozzle body and a plurality of V-shaped patterns circumferentially spaced and extending downstream from the downstream end. Each V-pattern includes an inner wall radially spaced from the outer wall, a root, and a tip axially spaced from the root. At least one V-pattern of the plurality of V-patterns includes a first section extending axially downstream from the root, a second section extending axially downstream from the first section, and a third section extending axially downstream from the second section to the tip. The inner wall extends along the first section, the second section, and the third section. The first segment is distinguishable from the second segment, and the second segment is distinguishable from the third segment.
