Sinopsis

This paper analyzes numerical simulations of the deposition of magnetic beads in a microchannel, with a nearby permanent magnet, under different conditions. Two different computational approaches are analyzed: the classical particle Lagrangian tracking and an Eulerian approach based on the balance of the magnetic and the drag forces. It has been found that for the conditions considered the Eulerian approach is adequate to simulate the dynamics of the particles. These simulations easily allow the tracking of the time evolution of the shape of the deposition and its effect on the flow as the deposition grows in time. The effect of the magnetization of the magnet on the time evolution of the accumulation of particles is analyzed.
