One or more protuberances are provided on a turbine blade on its suction side in a vicinity of its trailing edge. The protuberances serve to reduce a separation zone in a vicinity of a blade surface that is responsible for disturbances that affect efficiency of the turbine.
1. A turbine rotor blade, comprising: a pressure side and a suction side,wherein a majority of a surface of the suction side is smooth, except for at least one protuberance which is only provided at and along a trailing edge of the turbine rotor blade on the suction side, andwherein the pressure side is smooth. 2. A turbine rotor blade according to claim 1, wherein a location of the at least one protuberance along the trailing edge is selected to be in a vicinity of a maximum separation zone as calculated without the protuberance. 3. A turbine rotor blad...
