A stage for a turbomachine including a rotor and a stator 18. The rotor is disposed about a shaft of the turbomachine, operatively engages the shaft, and is configured to rotate in a circumferential direction. The rotor also has a plurality of blades. The stator 18 is in fluid communication with the rotor and is located axially adjacent to the rotor. The stator 18 includes a plurality of nozzle vanes 24, an interior circumferential surface 26, and an exterior circumferential surface 28. The plurality of nozzle vanes 24 are spaced circumferentially apart to channel a working fluid therebetween, and are also bowed, or curved, to create bowed wakes in the working fluid. The bowed wakes are configured to engage the rotor blades incrementally such that the effects of the periodic disruption of forces on the blades are more gradual and/or reduced. |
