内容記述タイプ | Abstract | |||||
内容記述 | Noise generated by a fan consists of the discrete frequency noise (DFN) and the turbulent noise. When the jet fan operates near the design point, the former is dominantly. The DFN consists of the noise due to rotation of the steady pressure field on the impeller blades and the noise due to the interaction of the impeller blades and the stator (strut). The rate of decay of the rotating pressure field noise is predictable and in the most cases the quickly decreases in proportion the distance from the rotor. Therefore, DFN observed away from the jet fan is mostly interaction noise which due to interact rotor-strut and rotor-distorted flow incoming the rotor | |||||
