Tonal noise of a controlled-diffusion airfoil at low angle of attack and Reynolds number

The acoustic signature of a controlled-diffusion airfoil immersed in a flow is experimentally characterized. Acoustic measurements have been carried out in an anechoic open-jet-wind-tunnel for low Reynolds numbers (from 5 × 104 to 4.3 × 105) and several angles of attack. As with the NACA0012, the ac...
