A theoretical model is proposed that describes the dynamics of an ultrasound-activated contrast microbubble at arbitrary distances from a wall. The model consists of two coupled equations that describe the bubble radial oscillation and the translation of the bubble center. The equations make it possible to simulate the interaction of the microbubble with the wall starting from large distances and...
The paper proposes a theory that describes acoustic microstreaming generated by a gas bubble oscillating near a rigid wall. Numerical simulations based on the proposed theory show that, if a bubble is driven near resonance, the presence of a wall increases considerably the intensity of acoustic microstreaming as compared to that in an infinite liquid. This increase results from the fact that the bubble...
