Fig. 7From: A theoretical study of serrated leading edges in aerofoil and vortical gust interaction noiseThe predicted sound pressure levels (in dB) of the scattered sound field on the upper surface at y=0+, where the vertical axis shows the spanwise coordinate and the horizontal axis shows the streamwise coordinate. Both coordinates are normalised by the sound wavelength at the frequency. The other set-ups are the same as those in Fig. 6Back to article page
