A closed-form solution for streaming and Lagrangian transport in a deforming circular cavity
Zijian Liu, Julian Olszewski, Yang Lin +3
Streaming from a deforming cavity wall serves micromixing, pumping and particle handling. We solve it in closed form in a two-dimensional circular cavity, for any azimuthal wall mo…
On the Quantification of Mixing in Microfluidics
Ali Hashmi, Jie Xu
Methods for quantifying mixing in microfluidics have varied largely in the past, and various indices have been employed to represent the extent of mixing. Mixing between two or mor…
Acoustophoresis in Variously Shaped Liquid Droplets
Gan Yu, Xiaolin Chen, Jie Xu
The ability to precisely trap, transport and manipulate micrometer-sized objects, including biological cells, DNA-coated microspheres and microorganisms, is very important in life…
Do surfaces with mixed hydrophilic and hydrophobic areas enhance pool boiling?
Amy Betz, Jie Xu, Huihe Qiu +1
We demonstrate that smooth and flat surfaces combining hydrophilic and hydrophobic patterns improve pool boiling performance. Compared to a hydrophilic surface with 7 degree wettin…
Use of a porous membrane for gas bubble removal in microfluidic channels: physical mechanisms and design criteria
Jie Xu, Regis Vaillant, Daniel Attinger
We demonstrate and explain a simple and efficient way to remove gas bubbles from liquid-filled microchannels, by integrating a hydrophobic porous membrane on top of the microchanne…
A bubble-powered micro-rotor: conception, manufacturing, assembly, and characterization
Jonathan Kao, Xiaolin Wang, John Warren +2
A steady fluid flow, called microstreaming, can be generated in the vicinity of a micro-bubble excited by ultrasound. In this article, we use this phenomenon to assemble and power…
