A system including: a first turbine segment comprising a first blade coupled to a first shank. The system also includes a second turbine segment including a second blade coupled to a second shank, as well as an elongated flexible seal disposed in a gap between the first and second shanks. The elongated flexible seal includes an opening configured to channel a fluid flow into a hollow region of the elongated flexible seal to induce expansion of the elongated flexible seal in the gap.

1. A system, comprising: a seal, comprising: a first elongated structure having a first axis;a first opening into the first elongated structure, wherein the first opening extends along the first axis;a first portion of the first elongated structure disposed on a first side of the first opening, wherein the first portion extends along the first axis;a second portion of the first elongated structure disposed on a second side of the first opening, wherein the second portion extends along the first axis, and the first and second portions are configured to pre-load the seal along a gap between first and second bucket segments of a turbine, wherein the first opening channels a fluid flow into a hollow region of the seal to induce expansion of the seal in the gap during operation of the turbine. 2. The system of claim 1, wherein the first portion comprises a first curved portion and the second portion comprises a second curved portion. 3. The system of claim 2, comprising a first flat portion of the first elongated structure, wherein the first flat portion extends along the first axis between the first and second curved portions. 4. The system of claim 2, comprising a first bulged portion of the first elongated structure, wherein the first bulged portion extends along the first axis between the first and second curved portions. 5. The system of claim 1, wherein the first elongated structure comprises a first C-shape extending along the first axis. 6. The system of claim 5, comprising a biasing element extending across the C-shape. 7. The system of claim 5, comprising a second elongated structure having a second C-shape extending along the first axis, wherein the first and second C-shapes are concentrically aligned about a common interior. 8. The system of claim 5, comprising a second elongated structure having a second axis, wherein the second elongated structure has a second C-shape extending along the second axis, and the first and second C-shapes face one another about a common interior. 9. The system of claim 8, comprising a biasing element extending across the common interior between the first and second C-shapes. 10. The system of claim 1, wherein the first elongated structure comprises a W-shape extending along the first axis. 11. The system of claim 1, the system further comprising the first bucket segment having the seal. 12. A system, comprising: a first turbine segment comprising a first blade coupled to a first shank;a second turbine segment comprising a second blade coupled to a second shank; andan elongated flexible seal disposed in a gap between the first and second shanks of a turbine, wherein the elongated flexible seal comprises an opening that channels a fluid flow into a hollow region of the elongated flexible seal to induce expansion of the elongated flexible seal in the gap during operation of the turbine. 13. The system of claim 12, comprising a biasing element disposed in the hollow region of the elongated flexible seal. 14. The system of claim 12, wherein the opening extends along an axis of the elongated flexible seal. 15. The system of claim 12, wherein the elongated flexible seal extends along the gap between the first and second shanks in a radial direction relative to a rotational axis of the first and second turbine segments, and the elongated flexible seal is disposed in an elongated recess in at least one of the first or second shank. 16. The system of claim 12, wherein the elongated flexible seal comprises at least one curved portion disposed about the hollow region, the curved portion extends about opposite sides of the opening, the opening extends along an axis of the elongated flexible seal, and the at least one curved portion extends along the axis of the elongated flexible seal. 17. The system of claim 16, wherein the at least one curved portion comprises a C-shaped portion that extends along the axis of the elongated flexible seal. 18. The system of claim 16, wherein the at least one curved portion comprises a W-shaped portion that extends along the axis of the elongated flexible seal. 19. A method, comprising: disposing an elongated flexible seal in a gap between first and second shanks of a turbine, wherein the elongated flexible seal comprises an opening that channels a fluid flow into a hollow region of the elongated flexible seal to induce expansion of the elongated flexible seal in the gap during operation of the turbine. 20. The method of claim 19, wherein disposing the elongated flexible seal in the gap comprises orienting the elongated flexible seal in a radial direction relative to a rotational axis of the first and second shanks, and disposing the elongated flexible seal in at least one of the first or second shank.
