The performance of a conventional axial flow fan and other fans, which have various types of rings fixed at the blade tips of the same fan, were compared. Then, the effects of these rings were investigated in detail. The fans displayed higher performance with a fixed ring. The authors also showed that a labyrinth seal is able to seal the tip clearance between the ring and the fan shroud of the fan with a fixed ring, especially when the fan operates in a low static pressure difference. As a result, the fan with a fixed ring and the labyrinth seal prevented the effect of the tip clearance, and achieved higher fan performance and lower fan noise than the conventional fan in any practical tip clearances.
