A vortex-reducing fluid guide component is disclosed. The fluid guide component includes a base portion and an upstanding body portion. An internally-cooled blending element extends between the base portion and a leading edge of the body portion. The blending element includes a deflection region that advantageously disrupts horseshoe vortex formation. The fluid guide component includes a supplemental cooling channel between the blending element and the intersection of the body portion leading edge and the base portion. In one embodiment, the supplemental cooling channel captures cooling fluid used to cool the blending member and provides additional cooling to the body portion leading edge/base interface. The component includes a strategically-perforated impingement panel or member that distributes cooling fluid to selected portions of the blending member, thereby ensuring that key regions within the blending member are efficiently cooled in accordance with temperature distribution.
