Abstract
Active flow control (AFC) has been proven to be an effective method to counteract flow disturbances and improve the performance of flow systems. Here, we compare the efficiency of open- and closed-loop AFC for a periodically disturbed compressor stator cascade flow. While still being effective in damping disturbances, it turned out that an additional efficiency gain could not be confirmed for this experiment.
