Abstract
Two-dimensional Stokes flow generated by an acoustic streaming around two circular cylinders were studied. A series solution method is developed to obtain both the potential and Stokes flows. Calculation results for two equal cylinders show that the streaming flow pattern undergoes six bifurcations with the direction of the oscillatory motion of the fluid when two bodies are at moderate or large distance. When they come closer, the pattern becomes more complicated especially in the gap region. The present solution method can be easily extended to an arbitrary arrangement of multiple circular cylinders with different radii.
