Wind tunnel measurements of three different airfoils are investigated using surface pressure microphones flush-mounted on the suction side of the airfoils. In stalled conditions, these microphones can be used to evaluate the convection velocity and the correlation length of the turbulent vortices that are generated in the separated region of the stalled flow. In addition, stall is characterized by the appearance of a spectral hump at relatively low frequencies that can be measured by the microphones located in the separated region. Using appropriate normalization and scaling, a nearly universal model that can represent the behavior of the surface pressure spectra in this low frequency range is devised.
