TURBINE INTRUSION LOSS REDUCTION SYSTEM |
| 摘要 |
Systems and devices configured to reduce windage and mixing losses in a turbine by redirecting and/or aligning a direction of a leakage flow with the flowpath of the main flow of a turbine are disclosed. In one embodiment, a device includes: a base configured to connect to a diaphragm of a turbine; and a radial portion connected to the base and extending radially inboard from the base toward a rotor of the turbine, the radial portion oriented to adjust a direction of travel of a leakage flow of working fluid radially inboard at an angle complementary to a primary working fluid path of the turbine. |

1. A device comprising:
a member configured to connect to an outermost diaphragm of a turbine and oriented to adjust a direction of a leakage flow of working fluid to a radially inboard direction at an angle complementary to a primary working fluid path of the turbine; and a first set of ridges extending from the member in an upstream direction relative to the member, each ridge in the first set of ridges circumferentially distanced from one another. |
