Abstract

PURPOSE: To reduce a secondary flow for higher internal efficiency of a turbine by bending downstream the leading edge of a flow course part in the vicinity of the upper and lower walls more than in the case of leading edge of a main flow part and shaping the circular size of the former leading edge larger than the leading edge of the main flow part.
CONSTITUTION: A turbine nozzle blade having a flow course 1 is disposed between the upper and lower walls 2, 3. A main flow part B has the highest efficiency. Leading edges (a), (c) of flow parts A, C in the vicinity of the upper and lower walls are successively bent in a streamlined shape downstram from the leading edge (b) of the main flow part B. A circular size of each leading edge (a), (c) is greater than that of the leading edge (b) of the main flow part, by which a fluid may be prevented from being separated, run along the profile of the blade and be rectified in the direction Y at the outlet. A secondary flow produced by a friction against the side wall can be reduced.
