Investigation on a Negative Magnetophoretic-inertial Combined Sortor for Non-magnetic Microparticles
摘要
Abstract
In order to sort non-magnetic micro-particles with a very close diameter,lateral migra-tion of negative magnetophoretic coupled inertial sorter might be numerically calculated for 3 kinds of non-magnetic particles of 3 μm,4 μm,5 μm in different magnetic fields for different microchannel pa-rameters,different inlet velocities and velocity ratios of two inlets.The numerical results show that, greater lateral migration of non-magnetic particles are induced by more powerful magnetic field and bigger particle diameters.Separation efficiency of non-magnetic particles promotes when lower inlet velocity and greater inlet-velocity ratio.Moreover,smaller H a/H band larger extension proportion in sorter are beneficial to particle separation.Partial numerical results verified by laser induced fluores-cence experiments may prove the validity of numerical model.关键词
