| Abstract: | The method is raised to reduce the turbulence noise by equipping metal net masks in the vane wheel.The influence of different structure parameters of metal net masks on turbulence noise is measured,and the noise in inlet and outlet of the centrifugal fan is reduced 3 5 dB(A) and 2 5 dB(A) by equipped metal net mask that the structural parameter is optimized in inlet of vane wheel. |
