Abstract

•Curved surfaces were salient geometrical features on artificial impeller blade wear.•LES was used to support simulations with the standard k–ε model.•3D printed impellers were used to conduct PIV measurements and flotation experiments.•PIV and flotation results supported the effects of blade wear on recovery.
