The Lattice Boltzmann Simulation of Magnetic Fluid

AbstractThe magnetic fluid is a multiphase system which property and morphology are affected by a number of internal and external forces such as the brown force, viscous force, magnetic force, van der Waals force, repelling force, gravity and buoyancy. All these forces are compared respectively in this paper in order to reduce the calculation process. And the four strongest kinds of forces are considered in the two-phase lattice Boltzmann model. With this model, we simulated the magnetic fluid and got the chainlike structure of magnetic particles under an external magnetic field. The validity of above two-phase lattice Boltzmann model is verified by the simulation results
