内容記述タイプ | Abstract | |||||
内容記述 | Discrete frequency noise (DFN) generated from a tubular centrifugal fan was investigated experimentally and theoretically.It was made clear that the DFN is caused by the interaction of the rotor blades with the distorted inlet flow, but not with the stator blades. It is effective for reducing the DFN level that the inlet nozzle is lengthened to the duct diameter and set the honeycomb in it. In the latter case, the DFN level can be reduced almost to the turbulent noise level. The DFN level was theoretically predicted. The prediction shows that the noise source concentrates to the leading edge of the blade. And the characteristic lengths are almost constant for any inlet distortion. The predicted noise level agrees with the experimental results. | |||||
