Flat Fluidics: Programmable On-Chip Networks for Biological and Chemical Applications

Wixforth A., University of Augsburg and Advalytix AG, DE

We present a novel approach towards the needs of a versatile microfluidic chip-based microfluidic system with unique properties and functionality. Like for microarrays and in contrast to many existing microfluidic technologies, the fluid handling is [...]

Modelling Annular Micromixers

Gleeson J.P., Roche O.M., West J., Gelb A., University College Cork, IE

The search for efficient mixing methods in the low Reynolds numbers flows typical of lab-on-a-chip technology has led us to propose an annular magnetohydrodynamic micromixer, currently under construction at the NMRC. In this talk we [...]

Mixing and Impulse Extremization in Microscale Vortex Formation

Mohseni K., University of Colorado, US

A key idea in microscale mixing, where the conventional turbulent mixing is not applicable, is to increase the area of the interface between two fluids. Significant entrainment and consequently mixing during vortex formation works based [...]

Magnetohydrodynamic Micromixing

Gleeson J.P., West J., University College Cork, IR

Modeling of magnetohydrodynamic (MHD) pumping in an annular microchannel is reduced to a two-dimensional Poisson equation for the azimuthal velocity. A method for enhancing the mixing of fluids is proposed, and is proven to yield [...]
