48 Citations | The experimental results show that a good coupled modification not only could reduce the fan noise but also could advance the fan performance and extend the operating range. |
6 Citations | The much smoother pressure distribution of the modified fan than that of the datum fan is the main mechanism of noise reduction of hollow blade root. |
52 Citations | Grooved blade tips amplify the fan noise, so measures should be taken to control the noise. |
64 Citations | The unsteady forces exerted on the fan blades constitute another noise generation mechanism, which affects the whole extension of the impeller, thus transmitting pressure fluctuations to the entire volute casing. |
10 Citations | Therefore, the noise observeda way from a low pressure axial flow fan is mostly the turbulent noise. |
10 Citations | The proposed form of the thickness noise enables to highlight the effect of each geometrical parameter of the fan on the overall thickness noise, on the one hand, and presents a fast computational mean and low memory storage capability since the acoustic pressure in the frequency domain is calculated for only one blade, on the other. |
39 Citations | The data presented indicates that this turbulence is the dominant source of noise above 1.5 kHz for the fan tested. |
| Such correlations may contribute to redesign guidelines for simultaneous reduction of noise and improvement of efficiency at prescribed fan performance. | |
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. |
| 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. |
