<P>PROBLEM TO BE SOLVED: To provide a turbine blade that reliably discharges droplets generated by the turbine blade passing through a leading edge region on a back side thereof to collide with the back side and flowing down along the back side, and adhering on a surface of the turbine blade while increasing as moving toward a blade root side outward the turbine blade. <P>SOLUTION: The turbine blade 1 has the back side 31, the blade root 37, and a blade tip 36, and rotates around a rotary shaft (not shown) as a center. A separation groove 2 is provided of which the part or all extend and which leads the droplets 7 adhering on the surface outward on the back side 31 downstream the center line 10 between the axial center line 11 of the turbine blade 1 extending toward the rotary shaft and a leading edge 8 of the turbine blade 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
