摘要：

A theory is presented for the capture of magnetic particles by a bed of spheres in high gradient magnetic separation. The laminar approximation to fluid flow is used in conjunction with the free surface condition (Happel's model) to obtain the fluid velocity profile near a representative collector sphere in the assemblage. An effective medium treatment is used to model the magnetic field, thus taking into account the effects of neighboring spheres. Results are reported for the capture of both paramagnetic and diamagnetic particulates by a filter operating either in the longitudinal or transverse design mode.
