Abstract
An impingement cooled component includes a first wall having a plurality of impingement holes and a second wall spaced apart from the first wall. The second wall is downstream of the first wall, relative to a cooling flow, the second wall has a contoured surface facing the first wall. The contoured surface includes a plurality of contours defined by at least one of a plurality of peaks and a plurality of valleys, and at least one of the contours in the plurality of contours is aligned with an axis defined by one of the impingement holes in the plurality of impingement holes.
