Micron-bubble streaming flow towards micron to sub-micron sized sorting
Micro-bubble streaming flows represent a unique type of actuating mechanism for microfluidics and have demonstrated great potential in the applications of micro-particle manipulation (e.g. size dependent trapping, sorting, and focusing etc.). The main object of this thesis work is to extend towards …

Quantifying particle sorting in microbubble streaming flows
… size-dependent behaviour of microparticles in a bubble streaming flow. We show that in microchannels, the steady streaming flow generated by an ultrasonically driven semicylindrical microbubble can be combined with a Poiseuille flow to achieve tunable, high throughput, size-sensitive sorting and …

A numerical study on microbubble mixer
… the micromixer, a device which actuates steady streaming by semi-cylindrical sessile bubble oscillations. The mixer's capability of producing chaotic mixing is confirmed and a numerical simulation that is in good agreement with the experiment is developed, which then leads to the exploration of …

Microbubble streaming flows for non-invasive particle manipulation and liquid mixing
… we study an emerging actuating mechanism -- microbubble steady streaming flows -- by emphasizing both fundamental understanding and the design and applications of bubble-based microfluidic devices. Under periodic acoustical driving, microbubbles with radius 20 -- 100µm absorbed or attached to a …
