METHOD AND APPARATUS FOR PROVIDING FILM COOLING TO TURBINE COMPONENT

Document Type and Number:

Japanese Patent JP2010019259

Kind Code:

A

Abstract:

To provide a method and an apparatus for applying film cooling to one or more turbine components.

A cooling gas flow passage (200) provides a cooling gas to a turbine component (100) with a hot gas path of a turbine. The cooling gas flow passage (200) includes at least one feed aperture (202) so as 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).
