Method and apparatus for providing film cooling to turbine components

Methods and apparatuses for providing film cooling to one or more turbine components are provided. A cooling gas flow passage (200) provides a cooling gas to a turbine component (100) with the hot gas path of a turbine. The cooling gas flow passage (200) includes at least one feed aperture (202) ope...

Zusammenfassung:	Methods and apparatuses for providing film cooling to one or more turbine components are provided. A cooling gas flow passage (200) provides a cooling gas to a turbine component (100) with the hot gas path of a turbine. The cooling gas flow passage (200) includes at least one feed aperture (202) operable to receive cooling gas from at least one cooling gas compartment (110) associated with a turbine component (100). The cooling gas flow passage (200) also includes at least one slot (206) with a converging portion (208) having a first opening (210) and a second opening (212), where the first opening (210) receives the cooling gas from the feed aperture (202), and the second opening (212) provides the cooling gas to at least a portion of an outer surface (102) of the turbine component (100).
