Abstract: The effect of an
air-separator to improve the low flow rate performance of an
axial flow fan has been discussed by the present paper. The
influence of its geometric parameters and different locations
ahead of the rotor on the performance of the air-separator was
described. It is found that the air-separator is the most
effective equipment for improving the unstable characteristics
of an axial flow fan. These investigations provide scientific
basis for understanding the working mechanism and choosing the
dimensions and structure of the air-separator of the fan.
