Effect of tip winglet angle on internal complex flow and aerodynamic performance of an axial fan

The effects of winglet angle on the flow characteristics in the tip clearance region of the AXF950 axial fan are studied in depth by numerical and experimental methods at different winglet angles (0°, 15°, 30°, 45°, 60°, and 90°). A comparison between the results of numerical simulations and those of experiments confir...

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...
