Multi-Objective Optimisation of a Centrifugal Pump Stage by Means of Design of Experiment Coupled with Inverse Design Method


Design Targets

  • Improve the impeller suction performance at design point.
  • Improve the stall performance.
  • Maximise pump head at shut-down.


  • Design guideline based on sensitivity analysis for impeller design.
  • Optimised impeller geometries for different objectives.
