Investigation of an Inversely Designed Centrifugal Compressor Stage


Using 3D Inverse Design to Redesign and Experiment on a Centrifugal Compressor Stage

This two-part paper describes the application and numerical and experimental validation of the 3D Inverse Design method to the design of a centrifugal compressor impeller with splitter blades.

The optimization of the splitter vane geometry by using conventional methods can be quite time-consuming, especially if the vane geometry is to be optimized three-dimensionally. In this two-parts paper, the application and numerical and experimental validation of the three-dimensional inverse design method TURBOdesign-1 to the design of a centrifugal compressor impeller with splitter is described.

In this paper:

 

  • Part I describes the input specification for the impeller and how its performance compares with the conventional design
  •  
  • Part II looks at a detailed experimental comparison of the flow field at the exit of the two impellers
  •  
  • Understand how an inverse method can be used to create higher performing compressor stage designs
