Query: Nonlinear electro-osmosis in dilute non-adsorbing polymer solutions with
  low ionic strength   Nonlinear behavior of electro-osmosis in dilute non-adsorbing polymer
solutions with low salinity is investigated with Brownian dynamics simulations
and a kinetic theory. In the Brownian simulations, the hydrodynamic interaction
between the polymers and a no-slip wall is considered with Rotne-Prager
approximation of Blake tensor. In a plug flow under a sufficiently strong
applied electric field, the polymer migrates toward the bulk, forming a
depletion layer thicker than the equilibrium one. Consequently, the
electro-osmotic mobility increases nonlinearly with the electric field and gets
saturated. This nonlinear mobility qualitatively does not depend on the details
of rheological properties of the polymer solution. Analytical calculation of
the kinetic theory for the same system reproduces quantitatively well the
results of the Brownian dynamics simulation.
