Abstract
Cavitation bubbles are present in a plethora of industrial and medical applications, and their understanding proves crucial to the development and tuning processes. In this study, we perform three dimensional direct numerical simulations (DNS) of multiple cavitation bubbles driven by pressure waves. Similarly observed in previously conducted experiments, it is found that these bubbles can exhibit an asymmetry in the direction of wave propagation. We show that this asymmetry is a consequence of the force induced by the wave on the bubbles, due to the finite speed of sound in the liquid medium.
