CFD modelling of magnetic nanoparticle suspension in microfluidics

In this paper a CFD model is presented to model the magnetic nanoparticle (MNP) suspension aggregation in a microfluidic device. The nanoparticles are injected to the microfluidic chip, which consists of serially connected microchambers. The device with the nanoparticle suspension is used to investigate enzyme-substrate reactions. The current work presents a dedicated two-phase solver for the nanoparticle suspension filling procedure of the chambers. The model relies on our measurements and a magnetorheological model, and it is created with the open source CFD software OpenFOAM.
