Magnetic fluids containing nano or submicron magnetic particles and their application in food, biological and pharmaceutical systems have recently attracted increasing attention. Magnetic particles can be collected efficiently in magnetizable matrices (e.g. iron wires) in high gradient magnetic separation (HGMS) process.

In this work, the dynamic buildup growth process is treated as a moving-boundary problem, in which the growing front of the buildup is tracked explicitly by marker points evenly distributed on its surface. The flow field and magnetic field are calculated using the finite element method (FEM). The simulation results with this dynamic model showed very good agreement with experimental results.
