内容記述タイプ | Abstract | |||||
内容記述 | The effects of three parameters; the location of the partition of impeller, the bare ratio and the outlet angle of scroll casing on the turbulent noise and aerodynamic characteristics, were experimentally investigated in the dual-cascades centrifugal fans. In this report, we proposed a new method to estimate the wake width which is an important parameter to calculate the turbulent noise. It was shown that the fan noise became lower when the bare ratio was from 9% to 25% and the outlet angle of scroll casing was about 20°. When the inlet/outlet area ratio of upper cascade was equal to that of the lower cascade and both of these are equal to about unity, the fan noise became lower. The predicted sound pressure level agrees well with the experimental values of the overall turbulent noise with L-weighting and A-weighting functions. | |||||
