Paper Abstract

In this study, we use the Lagrangian-Eulerian model, usually termed as Discrete Particle Model(DPM), and the Eulerian mixture model to numerically simulate the magnetophoresis-based separation of magnetic beads in a microfluidic system. The separation is based on High Gradient Magnetic Separation (HGMS) principle. A comparative assessment of both computational models was conducted. Mixture model provides a solution similar to that obtained using the DPM but with reduced computational time. However, the fidelity of mixture model can be attained only by the proper modeling of the slip velocity between the particle and the carrier fluid. For both of DPM and mixture approaches, the appropriate constitutive physics models for drag, lift, slip were resolved.
