A turbine stator wheel of a gas turbine with a plurality of stator vanes spaced apart around the circumference is provided. Two adjacent stator vanes form a passage each between the suction side of the one stator vane and the pressure side of the other stator vane starting from the vane trailing edge, which includes a constant passage portion in which the passage has a substantially constant passage cross-section. The constant passage portion has an inlet area and an outlet area. Each stator vane forms on the pressure side a rear area that extends, starting from the vane trailing edge adjoining the constant passage portion as far as the inlet area of the passage portion, and on the pressure-side forms a front area that extends upstream of the rear area. Each stator vane has on the pressure side a convex pressure-side contour.

A turbomachine has an annular main flow duct through which passes a flow, and in which is arranged at least one stator provided with stator vanes. The stator vanes each have at least one recess issuing into a flow duct inside the stator vanes and the flow duct issues into a bypass duct of the turbomachine via at least one outflow duct provided with a shut-off element.
