Abstract
Baffle inserts for airfoils of gas turbine engines are described. The baffle inserts include a baffle insert body having a first side portion and a second side portion, wherein each side portion has a respective end, a first set of vortex generation elements is arranged at the end of the first side portion, and a second set of vortex generation elements is arranged at the end of the second side portion. The first set of vortex generation elements and the second set of vortex generation elements are arranged at an aft end of the baffle insert body.

A baffle insert for an airfoil of a gas turbine engine, the baffle insert comprising:
- a baffle insert body having a first side portion and a second side portion, wherein each side portion has a respective end;
- a first set of vortex generation elements arranged at the end of the first side portion;
- and
- a second set of vortex generation elements arranged at the end of the second side portion,
- wherein the first set of vortex generation elements and the second set of vortex generation elements are arranged at an aft end of the baffle insert body,
- wherein the end of the first side portion is joined with the end of the second side portion and the first set of vortex generation elements and the second set of vortex generation elements are arranged in an alternating and overlapping pattern where the first side portion joins with the second side portion.
A component for a gas turbine engine comprising:
- an airfoil body having a pressure side hot wall and a suction side hot wall that join at a trailing edge of the airfoil body, wherein the airfoil body defines an interior cavity;
- and
- a baffle insert arranged within the interior cavity of the airfoil body, the baffle insert having a baffle insert body having a first side portion and a second side portion, wherein each side portion has a respective end, a first set of vortex generation elements arranged at the end of the first side portion, and a second set of vortex generation elements arranged at the end of the second side portion, wherein the first set of vortex generation elements and the second set of vortex generation elements are arranged at an aft end of the baffle insert body,
- wherein the end of the first side portion is joined with the end of the second side portion and the first set of vortex generation elements and the second set of vortex generation elements are arranged in an alternating and overlapping pattern where the first side portion joins with the second side portion.
