| Abstract | As part of the program of studies on centrifugal impellers, the problem of instability at low flows was investigated. The major cause was found to be flow detachment from the impeller vanes.
Slotted blades were found to be the most effective means of delaying this detachment, and extending the working range of the blower.
Low speed studies were confirmed by a test program on a high speed machine, where it was demonstrated that the improved flow range was accompanied by a general increase of efficiency.
The design and placement of the slots is discussed. |
