Abstract
Investigation of sound source in a flow separated from a sharp edged fence was discussed by simultaneous measurements of fluctuating static-pressure and aerodynamic sound. Sound source terms of Ribner's Dilatation theory were calculated with measured fluctuating static-pressure, and intensity of the sound source term, spectra, coherence and integral of coherent output power of aerodynamic sound and sound source term-were-discussed to determine flow regions contributing to aerodynamic sound generation. The results suggest that the separated shear layer contributes to a broaden. spectrum generation of aerodynamic sound, in particular a region clear the edge of the fence shows maximum contribution even though there is not outstanding characteristics in coherence.
