Simulation of the translational motion of few cavitation bubbles in an ultrasonic field

The experimentally recorded motions of two and three bubbles in an acoustic standing wave field are simulated by a particle model approach. The parameters are similar to typical environment in acoustic cavitation at 20 kHz (bubble equilibrium sizes of a few micron and pressure amplitudes larger than 100 kPa). Observed bubble paths can be sufficiently reproduced by the model within the range of experimental error of parameters.
