Abstract :
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.
