Numerical Study on a passive micromixer with sinusoidal channel walls

Afzal A., Kim K-Y, Inha University, KR
Mixing of liquid samples in microfluidic systems has attracted many researchers mainly due to small characteristic dimensions of these channels, absence of turbulence and small diffusion coefficients. Depending on the mode of operation, different realizations [...]

A simulation of microfluidic oscillator micromixer

Khelfaoui R., University of Bechar, DZ
Micromixing is particularly interesting for many microfluidic applications. In micrometric size devices, reaching an efficient mixing is often difficult, due to laminarization of the flow. As an example, efficient mixing may be obtained using a [...]

Discrete Mixing of Nanoliter Drops in Microchannels

Rhee M., Burns M.A., University of Michigan, US
We present the theory, simulations and experiments for discrete drop mixing in microfluidic systems. The generalized analytical solutions have been derived and confirmed by simulations and on-chip experiments. The discrete drop mixing occurs in three [...]

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 study on the novel micromixer with chaotic flow

Lee S-H., Kang H.J., Choi B.K., Sogang University, KR
We design that a fluid was rotated by a coupling between Lorentz force and a moving force of a electric charge in an electric field. And it generate barrier embedded chaotic flow to use mass [...]

Compact Model of a Laminar Micro Mixer

Cupelli C., Koltay P., Zengerle R., Santer M., University of Freiburg, DE
In this paper we discuss a novel approach towards a system-level description for microreactors. In particular, a compact model for laminar micromixers for fluids with different viscosities is presented. We show how the well known [...]

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 [...]

Simulation of Electrically-Excited Flows in Microchannels for Mixing Application

Meisel I., Ehrhard P., Forschungszentrum Karlsruhe GmbH, DE
In the present paper we propose a method for improved mixing in microchannels. The basic idea is to excite a secondary vortex flow around an obstacle within the micromixer by applying an external oscillatory electrical [...]
