Abstract
A wall of a component of a gas turbine engine includes first and second wall surfaces, an inlet located at the first wall surface, an outlet located at the second surface, a metering section commencing at the inlet and extending downstream from the inlet, and a diffusing section extending from the metering section and terminating at the outlet. The diffusing section includes a leading edge formed at an upstream end of the outlet, a trailing edge formed at a downstream end of the outlet, a body region upstream of the trailing edge, and a plurality of crenellation features located on the body region.

A wall of a component of a gas turbine engine, the wall comprising:
- first and second wall surfaces;
- an inlet located at the first wall surface;
- an outlet located at the second surface;
- a metering section commencing at the inlet and extending downstream from the inlet;
- a diffusing section extending from the metering section and terminating at the outlet, wherein the diffusing section comprises:
- a leading edge formed at an upstream end of the outlet;
- a trailing edge formed at a downstream end of the outlet;
- a body region upstream of the trailing edge;
- and
- a plurality of crenellation features located on the body region.
A method for producing a cooling hole having a plurality of crenellation features in a wall having first and second surfaces, the method comprising:
- forming an inlet at the first surface, wherein the inlet meters a flow of fluid through the cooling hole;
- forming a diffusing section between the inlet and an outlet at the second surface, wherein the diffusing section includes a leading edge formed at an upstream end of the outlet, a trailing edge formed at a downstream end the outlet generally opposite the upstream end, and a body region located upstream of the trailing edge;
- and
- forming a plurality of crenellation features on the body region of the diffusing section.
