A flow control technique for noise reduction of a rod-airfoil configuration Vrije Universiteit Brussel
Adaptive and flow control techniques have been investigated as possible noise reduction approaches in modern commercial aircraft and small unmanned air vehicles. In the present paper, a rotating cylinder is examined as a noise reduction device in a simplified airframe component. The rod-airfoil canonical benchmark is used as a test case and noise prediction is realized by a 3D hybrid computational aeroacoustics approach. The rod is rotated at ...
