Aerofoil dipole noise due to flow separation and stall at a low Reynolds number

International Journal of Heat and Fluid Flow Turner J.M. & Kim J.-W. Aircraft wings and wind-turbine blades generate aerodynamic noise and such noise becomes louder when they are operating at an off-design condition (i.e. a high incidence angle against the oncoming flow). This is due to the wing/blade section undergoes flow separation and stall which …
