| Abstract | |
In the present work, the Extremum Seeking Control (ESC) technique is applied to reduce noise generated by vortex shedding in a NACA0012 airfoil. High-fidelity simulations are conducted where a suction actuator is placed at the airfoil suction side. The ESC is implemented to minimize noise generation by finding the best position for actuator placement. Different actuation setups are tested and, in some cases, flow control provides a sound pressure level reduction of -11dB without flow reattachment. For higher actuator intensities, flow reattachment occurs leading to a steady flow with sound pressure level reduction of -70dB. (AU) | |
