Chaotic mixing using periodic and aperiodic sequences of mixing protocols in a micromixer

Kang T.G., Singh M.K., Kwon T.H., Anderson P.D., Eindhoven University of Technology, NL

We conducted a numerical study on mixing in a barrier embedded micromixer with an emphasis on the effect of periodic and aperiodic sequences of mixing protocols on mixing performance. A mapping method was employed to [...]

A Microfluidic Mixer for Chaotic Mixing of Magnetic Particles

Zolgharni M., Azimi S.M., Bahmanyar M.R., Balachandran W., Brunel University, UK

Magnetic isolation of specific biological entities through utilizing super-paramagnetic micro-particles has been of great interest in both bench-top and microfluidic platforms. Since the magnetic particles and target entities are suspended in separate fluids, prior to [...]

Chaotic flows in microchannels: A lattice Boltzmann study

Varnik F., Raabe D., Max-Planck Institut fuer Eisenforschung, DE

Lubricant flows are usually assumed to be laminar and the lubricatedmetallic surfaces are anticipated to be perfectly flat and references therein). Both assumptions are incorrectwhen it comes to a detailed analysis. Indeed, metallic surfaces arenever [...]

Numerical Visualization and Quantification of Chaotic Mixing for Micromixers

Kang T.G., Kwon T.H., Pohang University of Science and Technology, KR

We present a systematic way of visualization and quantification of mixing in chaotic micromixers with a periodic mixing protocol. We name it colored particle tracking method, which consists of three steps. One is flow analysis [...]
