Abstract
Magnetic fluids are suspensions of magnetic particles coated with a molecular layer of dispersant. The magnetic particles form chains in a magnetic field, which cause magnetic theological effects. Consequently the behavior of the particles under flow is an important subject for the analysis of the behavior of magnetic fluids. The present study proposed a numerical scheme in which the molecular dynamics simulation for the motion of the magnetic particles and the multi-particle collision dynamics simulation for describing the hydrodynamics interaction among the particles are coupled. This scheme can simulate typical behaviors of magnetic fluids such as the formation of particle clusters and the breaking and reconstruction of the chains under shear.
