BUBBLE SELF-PROPULSION SIMULATION USING ACCELERATED BOUNDARY ELEMENT METHOD

In the present study, bubble dynamics in potential flow is considered. The computational approach is based on the boundary element method (BEM) accelerated both via the fast multipole method (FMM) and the heterogeneous computing architecture (multicore CPUs and graphics processors). The dynamics of exited high-order surface modes of bubble and the transfer of energy between surface modes, which can lead to bubble self-propulsion, are studied.
