Abstract (en)
An apparatus for use in a gas turbine engine includes a wall (30) defining an exterior face (32), a first film cooling passage (36A) extending through the wall for providing film cooling to the exterior face of the wall, and a second film cooling passage (36B) extending through the wall adjacent to the first film cooling passage for providing film cooling to the exterior face of the wall. The first film passage includes a first vortex-generating structure (40A) for inducing a vortex in a first rotational direction in a cooling fluid passing therethrough, and the second film passage includes a second vortex-generating structure (40B) for inducing a vortex in a second rotational direction in a cooling fluid passing therethrough. The first and second rotational directions are substantially opposite one another.
