- Although effective in the suppression of the boundary-layer separation, the potential of the Dielectric-Barrier-Discharge plasma actuators to reduce the aerodynamic-noise remains largely unexplored in both the literatures and industries. Supported by the EPSRC Grant EP/K002309/1, this work fills the gap by utilising the plasma actuators to successfully reduce the high-amplitude, narrowband vortex-shedding tonal-noise generated by a flat-plate aerofoil with blunt trailing-edge. This article also develops other novel and effective noise-control mechanisms that only require low-electrical power input to the plasma actuators, which will certainly increase the impact and encourage a wider proliferation of the plasma technology to the industries.
