Optimisation of efficiency of axial fans
2014A three-stage research project has been executed to develop ducted axial-fans with increased efficiency. In the first stage a design method has been developed in which various conflicting design criteria can be incorporated. Based on this design method, an optimised design has been determined through the use of a genetic optimisation algorithm.

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 ...

The main objective of this study is to determine the flow in and around a cooling fan of an automotive engine by means of CFD computations using the commercial software package ANSYS Fluent. Two distinct external disturbances are applied: external flow characterized by the in-flow velocity U and covering plates placed on the suction side of the fan ...
