Recent Advances in Acoustics of Transitional Airfoils with Feedback-Loop Interactions: A Review

Recent Advances in Acoustics of Transitional Airfoils with Feedback-Loop Interactions: A Review

We discuss herein recent experimental and numerical studies examining resonant flow-acoustic feedback–loop interactions in transitional airfoils (i.e., possessing a notable area of laminar-to-turbulent boundary-layer transition) characteristic of low-to-medium Reynolds number flow regimes. Such inte...
