Abstract
A sealing arrangement for a turbine system includes a bucket having an outer tip and at least one bucket ridge extending radially outwardly from the outer tip, the at least one bucket ridge comprising an abradable material. Also included is a stationary shroud disposed radially outwardly from the outer tip of the bucket. Further included is at least one shroud ridge extending radially inwardly from the stationary shroud toward the outer tip of the bucket, the at least one shroud ridge comprising the abradable material.

A sealing arrangement for a turbine system comprising:
- a bucket having an outer tip and at least one bucket ridge extending radially outwardly from the outer tip, the at least one bucket ridge comprising an abradable material;
- a stationary shroud disposed radially outwardly from the outer tip of the bucket;
- and
- at least one shroud ridge extending radially inwardly from the stationary shroud toward the outer tip of the bucket, the at least one shroud ridge comprising the abradable material.
A sealing configuration for a turbine system comprising:
- a shroud assembly extending circumferentially around at least a portion of a turbine section;
- a radially inner region of the shroud assembly comprising a plurality of circumferential segments, each of the circumferential segments having a gap disposed therebetween, the gap defined by a first surface of a first circumferential segment and a second surface of an adjacent circumferential segment;
- and
- at least one ridge disposed at least partially within the gap and on at least one of the first surface and the second surface, the at least one ridge comprising an abradable material.
A method of sealing between two turbine components comprising:
- forming a first ridge along a first turbine component, the first ridge extending away from the first turbine component and comprising an abradable material;
- and
- forming a second ridge along a second turbine component, the second ridge extending away from the second turbine component into close proximity with the first ridge and comprising an abradable material.
