Abstract: A gas turbine includes a compressor and at least one combustor downstream from the compressor. The combustor includes a burner having an inner shroud extending axially along at least a portion of the burner, an outer shroud radially separated from the inner shroud and extending axially along at least a portion of the burner, and a plurality of stator vanes extending radially between the inner shroud and the outer shroud. The stator vanes have an inner end proximate the inner shroud and an outer end proximate the outer shroud. The burner further includes a vortex tip at one of either the inner end or the outer end of the stator vanes. The vortex tip provides a gap between the inner end and the inner shroud or the outer end and the outer shroud, and the vortex tip includes a plurality of fuel ports. The gas turbine further includes a turbine downstream from the combustor.

Abstract: A method of fabricating a component is provided. The component includes a substrate having an outer surface and an inner surface, where the inner surface defines at least one interior space. The fabrication method includes forming at least one groove in the outer substrate surface. Each groove extends at least partially along the outer substrate surface and has an asymmetric cross-section. The method further includes forming at least one access hole in the substrate. Each access hole connects the respective groove in fluid communication with the respective interior space. A coating is disposed over at least a portion of the substrate surface, such that the groove(s) and the coating together define one or more channels for cooling the component. A component is also disclose and has at least one groove with an asymmetric cross-section.
