摘要：

A method to calculate the unsteady flow fields and aeroacoustic sound pressure in the centrifugal fan of a vacuum cleaner was developed. The sound pressure was calculated by an acoustic analogy. It was stated that the proposed method can predict the peak sound pressure levels from the centrifugal fan within 3-4 dBA. The tonal sound pressure levels spectra of an acoustic pressure agree well with the measured data within 4 dBA deviation range.
