Acoustophoretic trapping of particles by bubbles in microfluidics

Frontiers in Physics, 2023
We present in this paper a simple method to produce strategic acoustic particle capture sites in microfluidic channels in a controlled way. Air bubbles are intermittently injected into a micro-capillary with rectangular cross section during a flow motion

Numerical simulations of non-spherical bubble collapse [PDF]

, 2009
A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a ...

An Alternative Method to Deduce Bubble Dynamics in Single Bubble Sonoluminescence Experiments [PDF]

, 2002
In this paper we present an experimental approach that allows to deduce the important dynamical parameters of single sonoluminescing bubbles (pressure amplitude, ambient radius, radius-time curve) The technique is based on a few previously confirmed ...
