説明

The study of sound generated by a pair of square cylinders placed side by side in a uniform flow is performed. The sound expected by Curie's method containing the Doppler effect is compared to the sound obtained by a direct numerical simulation (DNS). When the distance between the centers of the cylinders is small, the sound expected by Curle's method agrees with the sound obtained by DNS for the in-phase vortex shedding, but does not for the antiphase vortex shedding.
