Active control of rotor-stator interaction noise is studied numerically using a locally oscillating stator surface. A stator of 24 blades inside an infinite coaxial duct is considered. The governing equations are linearized three-dimensional Euler equations and solved with an explicit numerical technique based on a high-order approximation of spatial derivatives. A number of parameters governing actuation-induced sound field and control performance are investigated. It is found that the actuation-induced sound field and noise reduction achieved depend on the actuation amplitude and frequency. The side and position, where actuation is imposed, of the blade as well as actuator geometry are also crucial for the control performance. The downstream-radiated sound power may be reduced by 50% or more over a range of frequencies given an optimum combination of control parameters.
