Abstract:

To reduce the aerodynamic noise of axial fan, the hush characteristics of eagle owl feather with serration and strip structure was applied to the design of a coupling bionic fan. According to the experimental optimization, contrast experiments on the coupling bionic fan blade and traditional fan blade were carried out. The influence of the bionic serration and strip structure on the aerodynamic noise was studied. The results show that the aerodynamic noise generated by the coupling bionic blade was lower than that generated by the traditional blade. With fan speeds of 1000 r/min, 1100 r/min, 1200 r/min, 1300 r/min and 1400 r/min, the noise can be reduced at most 4.9 dB, 4.5 dB, 4.6 dB, 4.9 dB and 5.8 dB respectively.

Key words: engineering bionics, noise reduction, biological coupling, axial fan
