Abstract

PURPOSE: To prevent secondary flow and raise the efficiency, by providing passages at the bottom of the blade train to suck flow.
CONSTITUTION: Each passage 5 extends from the throat part of the blade to the outside through a platform 7 to suck the boundary layer produced at the throat part. Thereby, the secondary flow is guided to the outside and the boundary layer on the bottom wall is reduced by the suction. The non-uniformity of the speed is decreased. Therefore, the occurrence of the secondary flow is prevented and the efficiency of the turbine blade train is heightened.
