46 Citations | The paper illustrates how a computational fluid mechanic technique, based on stabilized finite element formulations, can be used in analysis of noise reduction devices in axial fans. |
12 Citations | It is apparent that the ability to decompose the output of the aerodynamic noise sources in the near field is a useful tool in designing fans to achieve desirable low-noise targets. |
11 Citations | The results of this research may provide proof of the parameter optimization and the structural design of small axial flow fans with low noise. |
286 Citations | It is concluded that broad band noise in fans arises from vortex shedding at the blade trailing edges under normal conditions, but that any large-scale turbulence in the flow can increase the noise significantly. |
24 Citations | In future, these results can anticipate reducing the broadband noise in automotive cooling fans. |
27 Citations | Although the main contribution to fan noise generation is due to mechanical sources, the bands in which aerodynamic noise is generated by these fans correspond to frequencies especially unpleasant to the human earl Therefore, the research presented in this paper may be of considerable interest, establishing a starting point for the design of quieter and more efficient fans. |
