Abstract

The improvement in efficiency of axial flow fans is major concern in turbomachinery industries including outdoor units of air conditioners. The end wall region is responsible for losses in axial flow fan. Researches on the relationship between the efficiency and the vortex occurring on the hub with a short length have been little found in the literature. Variations of the vortical flow field and the effects on the efficiency have been investigated with the entrance hub length and corner shape of the axial flow fan. The losses and the efficiency were evaluated by the stagnation pressure loss coefficient distribution calculated using commercial CFD solver SC/Tetra v12. The results show the efficiency was improved at specific entrance hub length due to the interaction between the hub vortex and the blade.
