摘要：
Electrical polarization strength of a particle is calculated by finite element method to obtain the dielectrophoretic and the secondary dielectrophoretic forces. Relying on the commercial software COMSOL Multiphysics 5.3a, the electrical polarization strength can be obtained in the AC/DC module from COMSOL, and then the module of particle tracing for fluid flow(PTF)is used to realize the dynamic simulation of particles on which the dielectrophoretic force, secondary dielectrophoretic force, fluid force and repulsive force are exerted. This novel method in which AC/DC module coupled PTF module in multi-physical fields provides an insight into the particle trajectories with positive or negative dielectrophoresis, which has a good agreement in other particle simulation methods. Whatever positive or negative dielectrophoresis is, these results imply that it is essential to consider secondary dielectrophoretic effect on metal electrodes to improve the prediction of experimental observation. © 2021, Editorial Department of Journal of Northeastern University.
