Abstract

In this paper the movement and aggregation of the magnetic nanoparticles are investigated numerically in the presence of magnetic field in a micro-sized domain. The nanoparticles are located in a microfluidic device, in which continuous fluid flow is applied. The numerical model is created with the open source CFD software OpenFOAM, by extending one of its Eulerian-Lagrangian based solver. The simulations show that in the magnetic field the particles are aggregating to chains, which are oriented parallel to the magnetic field. The aggregation procedure is dominated by the magnetic interactions between the particles due to their magnetization.
