Numerical Simulation of Flow Fractionation Characteristics of Magnetic Chromatography Using an HTS Bulk Magnet

Numerical simulation results for characteristics of separating multiple kinds of magnetic particles with different magnetic susceptibility by magnetic chromatography using high temperature superconducting bulk magnet are presented in this paper. The transient particle transport process of two kinds of particles with different magnetic susceptibility are numerically simulated. The calculated time evolutions of the particle concentration in the narrow channel of the spiral arrangement placed in the magnetic field produced by the highly magnetized high temperature superconducting bulk magnet show the flow velocity difference of the particle transport corresponding to the difference of the magnetic susceptibility. The numerical results also show that the separation of paramagnetic particles of 20 nm diameter is possible.
