摘要

本文用数值方法研究了磁性纳米颗粒在微尺度磁场作用下的运动和聚集。纳米颗粒位于微流控装置中，在该装置中施加连续流体流动。数值模型是利用开源CFD软件OpenFOAM，通过扩展其中一个基于欧拉-拉格朗日的求解器来创建的。模拟结果表明，在磁场作用下，粒子聚集成与磁场平行的链。粒子间的磁相互作用是聚集过程的主导因素。

Numerical modelling of magnetic nanoparticle dynamics in microfluidic devices

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.
