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.

Deliverables

• Design guideline based on sensitivity analysis for impeller design.

• Optimised impeller geometries for different objectives.

Impact
