The present communication is to provide a focus on two classes of fans that have been investigated in the writers laboratory! When the impeller blades are not rotating these adverse pressure gradients pump the flow in the direction opposite to the direction of the fan. Axial fans with severe pratcice regions should not be operated at blades angles, mass flow rat. Enhanced cooling fan performance with the aeroshroud of Figure .
Axial fans generally comprise fewer blades two to six than ducted fans. When the impeller blades are not rotating these adverse xaial gradients pump the flow in the direction opposite to the direction of the fan. Note that the signatures of the blades are well resolved in these data. Connect with:.

Foss 1 , Scott C. Morris 2 , Douglas R. Their distinguishing feature is that the pressure rise will be relatively small and the flow rate relatively large in comparison with prime movers of other designs, e. Numerous general discussions of axial fans exist; the following are among those that can be recommended: Wallis , Osborne , and Bleier The present communication is to provide a focus on two classes of fans that have been investigated in the writers laboratory. These two classes can be described in terms of the application areas served: automotive engine thermal management and agricultural building ventilation.
