Abstract
This works aims to perform a series of
experimental studies on flow control in a
low-speed, large-scale, axial flow compressor.
Specifically, air will be ejected from the rotor
blade trailing edge in an attempt to interact
with the stator downstream. Measurement
will be made on the rotor wake with and
without flow ejection, as well as the unsteady
force on the stator. Due to the thinness of the
rotor blade, the first year effort was mainly on
overcoming the tremendous difficulty in
obtaining an uniform ejected flow at 10%
chord downstream of the rotor trailing edge.
Various designs were attempted and the final
version uses embedded tubes within the blade
and ejected flow was also fine tuned using a
special technique. Results show an acceptable
uniform ejected flow.
