Electrophoretic motion of porous particles in a cylindrical tube at low Reynolds number


Members: Yao Xin, Wong Teck Neng, Marcos


Problems relating to transport and manipulation of porous particles involve hydrodynamic interactions due to multiple objects under the externally applied electric field. It is known that when a particle travelling within a confined geometry is exposed to an electric field, formation of the EDL on its surface exerts an electric force on the particle which alters the particle’s velocity. We proceed to construct a new mathematical model which can analytically solve for the velocities of particles within a cylindrical tube, under the influence of an externally applied electric field. Constructing such models will contribute to the understanding of situations in which the motion of each particle can be approximated as an isolated particle exposed to the electric field, or alternatively, when the particle-particle interaction has to be taken into account.
