| description | PROBLEM TO BE SOLVED: To provide a stator vane structure of an axial turbo machine that can reduce an exciting force to be applied to a rotor vane at a primary component of a stator wake frequency, with a simple structure and without changing an original property of the stator vane to accelerate a working fluid and a stator vane outlet angle determined when designing the stator vane alone.SOLUTION: The axial turbo machine has a stage structure combining a stator vane row 3 with a rotor vane row 4. Wake form bodies 11 are provided between stator vanes 8 configuring the stator vane row 3 arranged upstream of the rotor vane row 4. A cross-section view of each of the wake form bodies 11 at each position in a turbine radial direction is positioned downstream of a stator vane throat part 12 that is the narrowest of flow paths formed between the stator vanes 8 and upstream of a rotor vane row front edge line 13 of the rotor vane row 4 arranged downstream of the stator vane row 3. The shape of the cross-section view of each of the wake form bodies 11 at each position in the turbine radial direction is a wave line shape along with a stator vane chord parallel line 14 parallel to a vane chord line 10 of a stator vane cross-section view at the same position in the turbine radial direction. |
