Pulsating Ventilated Cavities as High Output, Low Frequency Underwater Sound Projectors

Abstract

SOW: Ventilated cavities are generated by introducing gas into the separated flow region behind a cavitator. When the ratio of the vaporous cavitation number to the cavity cavitation number is greater than 2.645, it is possible for the cavity to “pulsate”. This pulsation and its control will be investigated with experiments and computations.
