This paper presents the result of design optimization for three-bladed pump inducer using a three-dimensional inverse design approach, Computational Fluid Dynamics (CFD) and Design of Experiment (DoE) taking suction performance and cavitation instability into consideration. Cavitating and non-cavitating performances for inducers designed using the design variables arranged in the DoE table were analyzed by steady CFD.
The effective design parameters on suction performance and cavitation instability were confirmed by sensitivity analysis during the design optimization process.
