Theoretical model for acoustic streaming generated by a bubble near a wall

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 translation caused by the wave scattered by the bubble and then reflected from the wall is much stronger than the bubble translation in an infinite liquid, which is caused by the primary incident wave alone.
