Acoustic analysis of an axial fan
2017 16th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm), 2017Axial fans are often used in cooling electronic enclosures where low noise levels are highly demanded. Therefore, methods for predicting the noise emitted by an application including single or multiple fans are desirable to improve, stimulate and reduce the cost of low-noise design.

Volume 5: Turbo Expo 2004, Parts A and B, 2004
Flow reversal in axial fans is usually performed by the change of revolution direction and by stator vanes turning. Derived relations express the relative position of characteristics curves for reverse and normal flows. The ratio of volume flow rates at these conditions decreases with rotor blade profiles camber (aerodynamic loading) and with flow ...

Axial fan, centrifugal fan, and electronic equipment employing one of these fans
The Journal of the Acoustical Society of America, 2003A low-noise axial fan is provided with whirring sound minimized. The axial fan includes a plurality of blades arranged around a rotation axis at predetermined layout pitches. The blades are arranged at varied layout pitches. For instance, the layout pitch between the two adjacent blades may be different from the layout pitch between the remaining ...
