Comparison of Design Intent and Experimental Measurements in a Low Aspect Ratio Axial Flow Turbine With Three-Dimensional Blading
Keyword(s):
In recent years there has been considerable interest in improving turbine efficiency by the application of three-dimensional (3D) design techniques. However, there is no consensus on the optimum strategy to be adopted for this. The paper describes a strategy for the design of new 3D blading for a four stage model of a high pressure steam turbine. The new blading was tested and increased the turbine efficiency by 2% relative to the previous, very efficient 2D blading. Some details of the flow measurements in the turbine are presented and consideration is given to the effectiveness of current steady CFD codes to design this type of blading in the multistage environment.
