Cavitation microstreaming generated by a bubble pair in an ultrasound field.
An analytical theory has been developed to calculate the acoustic streaming velocity inside and outside bubbles for the case of a bubble pair suspended in an unbounded viscous liquid, taking into account the two predominant modes of a bubble pair: The volume and translation modes. It was demonstrated that the interaction between bubbles can affect the magnitude and direction of acoustic streaming, especially for tangential components outside of bubbles. The acoustic streaming intensifies as the radius of the neighboring bubble increases and is weakened as the distance between the bubbles increases.
