SEPARATION CONTROL BY SYNTHETIC JET ACTUATOR IN A STRAIGHT BLADE CASCADE

摘要

The paper deals with an experimental research of active boundary layer control using periodic excitation by a synthetic jet on a straight compressor blade cascade flow. Synthetic jet was introduced on the side wall of the tunnel perpendicularly into the main flow just in position of leading edge of compressor blades. Visualizations of the flow field on the wall and total loss coefficient were obtained.
