Claim 25:
26. A turbine system component for a turbine system, the turbine system component comprising:
a body having an exterior surface;
a cooling passage defined in the body and extending to an exterior surface of the body, the cooling passage having a first cross-sectional area; and
a hollow member coupled in the cooling passage and defining a first exit opening at the exterior surface of the body, the first exit opening in the hollow member having a second cross-sectional area that is less than the first cross-sectional area,
wherein the hollow member is made of a material having a melt temperature higher than an operating temperature of the turbine system, and
wherein the cooling passage has the first cross-sectional area from an inner end of the cooling passage to an inner end of the hollow member, a third cross-sectional area at the inner end of the hollow member, and the second cross-sectional area from the inner end of the hollow member to the first exit opening, wherein the third cross-sectional area is smaller than the first cross-sectional area, is at least as large as the second cross-sectional area, and is defined by a shape of an internal surface of the hollow member at the inner end of the hollow member.
