To study the effect on performance of different blade distortion laws of axial flow fans, the
radial distributions of blade stagger angle were fit as Bézier curves, and five distribution laws …

In the context of the rapidly evolving field of building ventilation, fan noise control stands out
as a pivotal technology to enhance the quality of life. This study aimed to elucidate the …

The performance of low-pressure axial flow fans is directly affected by the three-dimensional
bending and twisting of the blades. A new blade design method is adopted in this work …

The impeller and volute of a centrifugal fan are designed to be coaxially placed; however,
the impeller might be inclined about the central axis of the volute due to installation fault …

Several rotors of axial-flow fans and side channel blowers with optimal circumferential
spacing have been tested in a hemi-anechoic chamber; such rotors have been designed by …
