High-dimensional multi-objective aerodynamic optimization of a centrifugal air pump through improved impeller–diffuser matching via blade recambering and three-dimensional stacking
This work presents a surrogate-assisted multi-objective aerodynamic optimization of a centrifugal air pump through joint reshaping of the impeller blade and diffuser vane. A 22-dimensional design space is constructed using Bézier-based recambering, leading-edge lean, and independently varied hub and shroud stagger angl...
