AB  - The wake behind a NACA0012 wing at incidence with cut-in sinusoidal trailing edges(TE) is experimentally investigated. A wing model with interchangeable trailing edges isused to study their impact on the wake properties. Both vertical and span-wise traversesof hot-wires are done at different downstream positions, to obtain the downstream evolutionof statistical properties and to perform spectral analysis. Stereoscopic particle imagevelocimetry is used to study the flow structure in a span-wise/cross-stream plane.Span-wise inhomogeneity of the velocity deficit and of the wake width is observed andexplained by the presence of a span-wise/cross-stream flow induced by the cut-in modifications.Spectral analysis shows a decrease of shedding intensity with shorter TE wavelength,with up to 57% reduction when compared to a straight blunt wing. Blunt sinusoidal TEsoffer a reduction of span-wise correlation compared to the blunt straight one, which ismitigated when compared to an unmodified wing. A sharp cut-in design is also studied,that exhibits a more broad-band shedding spike at a lower frequency.
