Experimental Evaluation of Air Injection for Actuation of Rotating Stall in a Low Speed, Axial Fan |
Abstract |
This paper presents an experimental invest … This paper presents an experimental investigation of the effects of
air injection on the rotating stall instability in a low speed axial
compressor. Two experiments concerning air injection were tried. The
first experiment used a continuous forcing perpendicular to the flow
in the same or opposite direction of the tip velocity. The results
show a dramatic difference between the two directions, with opposite
direction forcing causing a significant increase in performance, and
same direction forcing causing a significant decrease in performance.
This result contradicts the Emmons stall propagation model. The
second experiment investigated the differences with respect to
different frequencies of air injection, with the injector pointed at
the fan, parallel to the flow. We found that the change in the
compressor characteristic in the unstalled region was highly dependent
upon the forcing frequency with the maximum change occurring near the
frequency of stall. nge occurring near the
frequency of stall. +
