BULGED NOZZLE FOR CONTROL OF SECONDARY FLOW AND OPTIMAL DIFFUSER PERFORMANCE |
| 摘要 |
A turbine nozzle configured to be disposed in a turbine includes a suction side, a pressure side, and a bulge disposed on the suction side. The suction side extends between a leading edge and a trailing edge in an axial direction and transverse to a longitudinal axis of the turbine nozzle, and extends a height of the turbine nozzle in a radial direction along the longitudinal axis. The pressure side is disposed opposite the suction side and extends between the leading edge of the turbine nozzle and the trailing edge of the turbine nozzle in the axial direction, and extends the height of the turbine nozzle in the radial direction. The bulge is disposed on the suction side protruding relative to the other portion of the suction side in a direction transverse to both the radial and axial directions. The turbine nozzle has a first periphery defined at a first cross-section at a first location along the height of the turbine nozzle by selected coordinate sets listed in Table 1. |

1. A turbine nozzle configured to be disposed in a turbine comprising:
a suction side extending between a leading edge of the turbine nozzle and a trailing edge of the turbine nozzle in an axial direction and transverse to a longitudinal axis of the turbine nozzle, and extending a height of the turbine nozzle in a radial direction along the longitudinal axis; a pressure side disposed opposite the suction side and extending between the leading edge of the turbine nozzle and the trailing edge of the turbine nozzle in the axial direction, and extending the height of the turbine nozzle in the radial direction; and a bulge disposed on the suction side of the turbine nozzle protruding relative to the other portion of the suction side in a direction transverse to both the radial and axial directions; wherein the turbine nozzle has a first periphery defined at a first cross-section at a first location along the height of the turbine nozzle by selected coordinate sets listed in Table 1. |
