- 1107 Effects of distance between plates on aerodynamic sound around a cascade of flat plates
抄録
In order to clarify the effects of the distance between the plates on aerodynamic sound and flows around a cascade of flat plates, wind tunnel experiments were performed with the various ratios of the distance between the plates to thickness, s/b = 0.5, 1.0, 1.5, 3.0, 6.0 and 13.0. For s/b = 6.0 and 3.0, the intense aerodynamic sound with acoustic resonance radiates. For the large distance of s/b = 13.0, as the freestream velocity increases, the variation of the sound pressure level does not have local maximum. This indicates that acoustic resonance becomes weaker. For the smaller distance of s/b = 1.0, the frequency of the vortex shedding from each plate differs between neighboring plates. As a result, the resonant acoustic radiation becomes weaker. For the much smaller distance of s/b = 0.5, the intense vortex formation does not occur in the wake of each plate and intense tonal sound does not radiate.
