Abstract

See full text

In order to desirably prevent leakage of a working fluid from the tip clearance to reduce loss of a heat drop of the working fluid, a first corresponding blade of a second stationary blade row, which corresponds to a first reference blade of a first stationary blade row, is disposed in a position distant by 2L from the position of a lower end of a rotor blade in the direction of movement of the rotor blades when the rotor blade makes the closest approach to a lower end of the first reference blade. It should be noted that L is a value obtained by multiplying the average time T required for the high-pressure working fluid to pass through the rotor blade by the traveling speed U of the rotor blade. On the other hand, a second corresponding blade of the second stationary blade row, which corresponds to a second reference blade of the first stationary blade row, is disposed in a position of a lower end of a rotor blade when the rotor blade makes the closest approach to a lower end of the first reference blade.
