Abstract
A turbine nozzle device (100) including a plurality of stator vanes (90), a flow path (92) being defined between a leading edge part of each stator vane and a trailing edge part of the adjoining stator vane, wherein the flow path includes an inlet (92A), an outlet (92B) and a throat (92C) located between the upstream part and the downstream part and narrower than the inlet and the outlet, and a surface of the trailing edge part of each stator vane that faces the flow path includes a steeply inclined part (91) which is located downstream of the throat and more steeply inclined than a part of the surface upstream of the throat.
Claims8
A turbine nozzle device including a plurality of stator vanes, a flow path being defined between a leading edge part of each stator vane and a trailing edge part of the adjoining stator vane,
- wherein the flow path includes an inlet, an outlet and a throat located between the inlet and the outlet and narrower than the inlet and the outlet, and
- a surface of the trailing edge part of each stator vane that faces the flow path includes a steeply inclined part which is located downstream of the throat and more steeply inclined than a part of the surface upstream of the throat so as to form a widening part of the flow path extending from the throat or a point adjacent to the throat to the outlet.
