Structure design of low-frequency broadband sound-absorbing volute for a multi-blade centrifugal fan

Applied Acoustics, 2020
Abstract A novel low-frequency broadband sound-absorbing structure is proposed for the noise reduction of an existing multi-blade centrifugal fan in range hoods. Incorporating the advantages of both sound absorption materials and micro-perforated panel absorbers in series and in parallel with unequal cavity depths, the compound absorber is designed ...

Research on blade design method of multi-blade centrifugal fan for building efficient ventilation based on Hicks-Henne function

Sustainable Energy Technologies and Assessments, 2021
Abstract The customary single-arc blade applied in the multi-blade centrifugal ventilating fan for building ventilation is ordinary in shape and hard to meet the design requirements of the pertinent parameters. The article used the modified Hicks-Henne function (suitable for blade design with multi-arc and complex curve blades) to parametrically ...
