Abstract
According to one aspect of the invention, a turbine assembly includes a stator and a rotor adjacent to the stator. The turbine assembly also includes a passage formed in a projection from the rotor to form a fluid curtain between the rotor and stator, wherein the fluid curtain reduces a flow of fluid into a hot gas path.
Claims19
A turbine assembly comprising:
- a stator,
- a rotor adjacent to the stator;
- and
- a passage formed in a projection from the rotor to form a fluid curtain between the rotor and stator, wherein the fluid curtain reduces a flow of fluid into a hot gas path.

A method for reducing fluid flow between turbine components comprising:
- flowing a hot gas across a nozzle on a stator;
- flowing the hot gas across a bucket on a rotor adjacent to the stator;
- flowing a cooling air flow through inner portions of the stator and rotor;
- and
- forming a curtain of fluid between the stator and rotor to reduce leaking of the flow of cooling air into the flow of hot gas.
