In this study, three-dimensional particle-based simulations are used to model
magnetorheological fluids. The numerical model of the MRF is implemented in the framework
of the Discrete Element Method (DEM) and takes into account the coupling of the
magnetic dipoles, the hydrodynamic drag forces and steric forces between particles. To
accurately treat the magnetic interaction between particles, the magnetic field at the
particles’ position is computed and an appropriate magnetization model is implemented.
DEM simulations with different volume fractions of the MRF are carried out and the
resulting magnetization curves are put in comparison with experimental data
