PERFORMANCES OF 3D FLOW IN TURBINE STAGES UNDER DIFFERENT SHAPES OF MERIDIAN PLANE

Abstract

Abstract: Using the code of simulation for three-dimensional flow field in turbomachinery, the performances of 3D flow in turbine stages which is made by Nanjing Turbine and Electric Machinery Co. Ltd under different shapes of meridian plane are studied. It is found that proper negative curvature of meridian plane will be good for the reduction of the reaction and leakage at tip, and will improve the performances of aerodynamics in flow passage. The work is of value to design long blade for turbo-machinery.

Key words: Meridian plane, Steam turbine, Three-dimensional flow field
