Migration of an electrophoretic particle in a weakly inertial or viscoelastic shear flow
Aditya S. Khair, Jason K. Kabarowski
Abstract
The cross-streamline migration of a spherical particle undergoing electrophoresis in weakly inertial or viscoelastic simple shear flow is quantified via asymptotic analysis. The findings for the migration direction and speed are in reasonable agreement with previous experimental studies on migration of electrophoretic colloids in Poiseuille microchannel flow.
