Abstract: An acoustic technique designed to increase the gas-dissolution rate of a bubble in a liquid media is proposed. Increased gas-dissolution rate is achieved by increasing the bubble's surface-to-volume ratio via bubble fragmentation. This is achieved by attaching an electroacoustic transducer to the system or load in which bubbles travel and exciting the transducer at the frequency of resonance. The electric resonance of the transducer attached to the system corresponds in frequency to the mechanical resonance of the system or load which allows for achieving such state without the use of an internally placed hydrophone to certify the resonance state. The acoustic bubble fragmentation technique increased the dissolution rate 4 to 5 times of bubbles with initial diameters between 150 and 550 ?m in distilled water and in medical grade saline solution.
