20 Citations | In this paper, an improved algorithm for active control of fan noise is proposed. |
This noise may have both tonal and random components and is strongly dependent on the way that the fan is placed in the unit and on how close its operation is to the design operating point. | |
10 Citations | Therefore, the noise observeda way from a low pressure axial flow fan is mostly the turbulent noise. |
26 Citations | The results show that under the abnormal condition, fan performance is lower than normal value and the noise rises. |
07 Jun 2010 15 Citations | Furthermore the acoustic output at the presence of parameter variations provides guidelines for the design-to-noise of fan components. |
The method described and applied in this work provides a good qualitative prediction of the noise generation when designing a new fan, thus facilitating the choice of the lowest noise fan from several feasible alternatives. | |
18 Citations | The results indicate the limits of maximum noise reduction which manufacturers may expect using existing fan designs and also indicates the methods for achieving maximum noise reduction for these configurations. |
15 Citations | In addition, new sources caused by the interaction between the stationary distortion and the fan blades appear and contribute to the inlet noise. |
10 May 2004 18 Citations | A comparative study shows that the potential acoustic shielding effect is less favourable to the jet noise than to the downstream fan noise. |
23 May 2005 20 Citations | These computations show that the acoustic directivity pattern of fan noise is strongly modified when the jet mean flow is included in the simulation. |
