A turbine nozzle disposed in a turbine includes a suction side having a bulge, and a pressure side. The suction side and the pressure side extend opposite one another between a leading edge and a trailing edge in an axial direction transverse to a longitudinal axis of the turbine nozzle, and extends a radial direction along the longitudinal axis. 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.
