Abstract

A study of the control of pairing sound of two identical thin vortex rings by means of a thin control vortex ring of opposite circulation is reported. Amplification and attenuation of the pairing sound have been observed. The amplification and attenuation are due to the effect of the control vortex ring on the interaction of the two pairing rings. Four basic types of interaction of the three interacting vortex rings and different degrees of amplification and attenuation have also been established.
