Strongly nonlinear dynamics of electrolytes in large ac voltages
Laurits H. Olesen, Martin Z. Bazant, Henrik Bruus
We study the response of a model micro-electrochemical cell to a large ac voltage of frequency comparable to the inverse cell relaxation time. To bring out the basic physics, we co…
Kilohertz microfluidics as an analytical tool for determining dynamic characteristics of microfluidic systems
Soren Vedel, Laurits H. Olesen, Henrik Bruus
The advent in recent years of highly parallelized microfluidic chemical reaction systems necessitates an understanding of all fluid dynamic time scales including the often neglecte…
Optimal homogenization of perfusion flows in microfluidic bio-reactors; a numerical study
Fridolin Okkels, Martin Dufva, Henrik Bruus
To ensure homogeneous conditions within the complete area of perfused microfluidic bio-reactors, we develop a general design of a continuously feed bio-reactor with uniform perfusi…
A numerical analysis of finite Debye-length effects in induced-charge electro-osmosis
Misha Marie Gregersen, Mathias B. Andersen, Gaurav Soni +2
For a microchamber filled with a binary electrolyte and containing a flat un-biased center electrode at one wall, we employ three numerical models to study the strength of the resu…
