ABSTRACT:
An apparatus of stationary blade for an axial flow turbine includes a diverging flow channel for flowing an elastic fluid and stationary blades which are fixed at the diverging flow channel and are curved in perpendicular direction to the flow direction of the elastic fluid. The stationary blades form the same tangential lean angles at the leading edge and the trailing edge of the stationary blade corresponding to the flow direction of the elastic fluid, and an axial flow turbine has the apparatus of stationary blades thereof. The stationary blade distributes the fluid in the flow channel uniformly and, consequently, improves the efficiency of the flow.
