Carefully timed tandem microbubbles have been shown to produce directional and targeted membrane poration of individual cells in microfluidic systems, which could be of use in ultrasound-mediated drug and gene delivery. This study aims at contributin

The dynamics of a bubble in a dilute bubbly water-air mixture is investigated experimentally and the results compared with a simple homogeneous compressible fluid model in order to elucidate the requirements from a better advanced numerical solution.

A geometrically simple configuration of a gas bubble expanding in a bubbly medium is chosen to study multi-scale modeling approaches in simulating multiphase flows. Three solvers following the Eulerian-Lagrangian, multi-component compressible and ana
