    报告摘要:Ferrohydrodynamics (FHD) describes the motion of a magnetic fluid, usually called a ferrofluid. A ferrofluid is a stable colloidal fluid consisting of nanoscale ferromagnetic particles suspended in a carrier fluid. A colloidal ferrofluid can keep magnetization and fluidity under the action of an external magnetic field. In this talk, we propose unconditionally energy-stable, and fully discrete finite element schemes for the FHD model. We obtain the existence and uniqueness of the numerical solutions b, and prove the unconditional convergence. Numerical experiments simulate the controllability of the magnetic fluid driven by an applied magnetic field.
