Abstract
The casing treatment system includes a compressor having an injection port, an extraction portion, a recirculation channel. It is also contemplated for the casing treatment system to include a plurality of injection ports, a plurality of extraction ports, and/or a plurality of recirculation channels. The casing treatment system is based on using the differences in the flow field at peak efficiency and near stall to “turn on” the recirculation at near stall operation to extend the stall margin, and to “turn off” the recirculation at peak efficiency operation to minimize impact to efficiency.
