Interactions of Magnetic Particles in a Rotational Magnetic Field

A. Weddemann, A. Auge, F. Wittbracht, S. Herth, A. Hütten
Bielefeld University, Germany

Particle-particle interactions are usually neglected when considering the behaviour of magnetic particle's so called magnetic beads in e.g. a microfluidic device. However, if the particle density exceeds a critical limit, this assumption might not lead to proper results anymore. In this ... En savoir plus

Superhydrophobic Surfaces for Friction Reduction Applications

Y. K. Hwa [1]
[1] National University of Singapore, Singapore

The present work investigates the role of suspended liquid-gas interfaces for applications involving the reduction in flow resistance using the COMSOL multiphysics software. A pressure-driven viscous flow of a liquid through microtubes containing superhydrophobic surfaces patterned with ... En savoir plus
