Samenvatting

The noise emitted by the interaction of a turbulent jet with an airfoil is considered. The incoming-turbulence noise mechanism is assumed to be the dominant noise source. Amiet's broadband noise theory is combined with a semi-empirical description of the turbulent field. The turbulence characteristics of the transitional shear layer are obtained from particle image velocimetry measurements. The turbulence energy spectra are found to compare well with Liepmann's isotropic model. This model is combined with Amiet's theory to predict the noise that would be emitted by a 1-meter span airfoil uniformly submitted to a turbulence with the same characteristics as found in our jet.
