pre-print
Acoustic streaming can be generated around sharp structures, even when the acoustic wavelength is much larger than the vessel size. This sharp-edge streaming can be relatively intense, blueowing to the strongly focused inertial effect experienced by the acoustic flow near the tip. We conducted experiments with Particle Image Velocimetry to quantify this streaming flow through the influence of liquid viscosity ν, from 1 mm^2/s to 30 mm^2/s, and acoustic frequency f from 500 Hz to 3500 Hz.
