In this sixteenth part of the series on “Acoustofluidics – exploiting ultrasonic standing waves forces and acoustic streaming in microfluidic systems for cell and particle manipulation,” we continue our discussion on the analytical aspects of the streaming phenomenon. In particular, the use of the singular perturbation technique for this class of problems is delineated with a set of examples where fluid-fluid interaction takes place. In this category, we focus on drops and bubbles, and deal specifically with the effect of interfacial mobility on the streaming flow.
