Abstract
According to one aspect of the invention, a turbine assembly includes a first bucket with a first slashface and a second bucket including a recess formed in a second slashface of the second bucket, wherein the second slashface is adjacent to the first slashface when the first bucket is positioned adjacent to the second bucket. The turbine assembly also includes a pin configured to be placed in the recess, wherein the pin is magnetically urged toward the first slashface to reduce fluid flow between the first and second buckets.
Claims20
A turbine assembly comprising:
- a first bucket with a first slashface,
- a second bucket including a recess formed in a second slashface of the second bucket, wherein the second slashface is adjacent to the first slashface when the first bucket is positioned adjacent to the second bucket;
- and
- a pin configured to be placed in the recess, wherein the pin is magnetically urged toward the first slashface to reduce fluid flow between the first and second buckets.
A method for reducing fluid flow between turbine components comprising:
- flowing a hot gas across a first bucket and second bucket, wherein the first and second buckets are adjacent;
- flowing a cooling air flow through a radially inner portion of the first and second buckets;
- and
- positioning a pin between the first and second buckets, wherein a magnetic property urges the pin toward a first slashface of the first bucket, wherein the pin reduces fluid flow between the first and second buckets.
A turbine assembly comprising:
- a first component with a first surface,
- a second component with a second surface configured to be adjacent to the first surface when the first and second components are adjacent;
- and
- a member configured to be placed between the first and second components, wherein the member is magnetically urged toward the first surface to reduce fluid flow between the first and second components.
