Abstract

The DBD Plasma actuator consists of two electrodes which exert the body force resulting from the electrical excitation and is used as a tool for active flow separation control. In the current research, the control of flow separation in a linear cascade of axial compressor blades has been experimentally investigated using a DBD plasma actuator and boundary layer suction. The experimental results show that using the DBD plasma actuator in the chord position of 30%, leads to 31% decrease in the energy dissipation, and also improves the performance of the compressor cascade blades. Likewise, applying the DBD plasma actuator in the velocity of 10 m/s results in the decrement of 19.1% in total pressure loss parameter. Also, utilizing the boundary layer suction device in the same velocity, leads in elimination of low energy part of the flow, and then decreases the total pressure loss parameter up to 14%. The performance of the linear axial compressor cascade blades using a DBD plasma actuator and boundary layer suction has been investigated and reported.
