Abstract:
A turbine nozzle according to the disclosure is a turbine nozzle that is used in a radial turbine and includes a ring-shaped hub, a plurality of nozzle vanes that are arranged at equal angular intervals on the hub, and a flow path that is formed between the nozzle vanes. The flow path includes a throat that has a smallest flow path cross-sectional area with respect to a flow direction of working fluid. On a downstream side of the throat with respect to the flow direction, the flow path cross-sectional area increases. Heights of the nozzle vanes on the downstream side of the throat with respect to the flow direction are greater than heights of the nozzle vanes in the throat and gradually increase from an upstream side toward the downstream side with respect to the flow direction.

Claim (Index 7):
The turbine nozzle according to  claim 5 , wherein,\n provided that an angle between a plane including the central axis and the airfoil center line is defined as an angle \u03b2, the angle \u03b2 linearly changes in a section in the second portion that includes the downstream end and that has a specified length.
