Leading Edge Surface Pressures from Airfoils in a Turbulent Flow

Abstract

Surface pressure cross spectral measurements near the leading edges of a variety of airfoils in a turbulent flow disclose contributions from the near fields of the diffracted pressures and the incident pressures from the grid-generated turbulence. The thickness dependence of the measured cross spectra of the near field components of the diffracted surface pressures corresponds to the thickness dependence of the dipole sound measured in the far field.
