Diffusioosmosis of electrolyte solutions in axisymmetric channels
Elena F. Silkina, Evgeny S. Asmolov, Olga I. Vinogradova
We present a theory of a flow of salt solutions in long axisymmetric channels induced by concentration and pressure drops between their ends. The consideration is restricted to thi…
Tuning diffusioosmosis of electrolyte solutions by hydrostatic pressure
Elena F. Silkina, Evgeny S. Asmolov, Olga I. Vinogradova
When two reservoirs of a distinct salinity are connected by channels or pores, a fluid flow termed diffusio-osmotic is generated. This article investigates the flow emerging in an…
Enhanced zeta potentials caused by surface ion mobilities
Evgeny S. Asmolov, Elena F. Silkina, Olga I. Vinogradova
The electro-hydrodynamics near conducting walls is revisited. Attention is focused on the impact of an explicit diffuse Stern layer, which permittivity and viscosity differ from th…
Instability of particle inertial migration in shear flow
Evgeny S. Asmolov, Tatiana V. Nizkaya, Jens Harting +1
In a shear flow particles migrate to their equilibrium positions in the microchannel. Here we demonstrate theoretically that if particles are inertial, this equilibrium can become…
Inertial migration of oblate spheroids in a plane channel
Tatiana V. Nizkaya, Anna S. Gekova, Jens Harting +2
We discuss an inertial migration of oblate spheroids in a plane channel, where steady laminar flow is generated by a pressure gradient. Our lattice Boltzmann simulations show that…
Achieving large zeta-potentials with charged porous surfaces
Olga I. Vinogradova, Elena F. Silkina, Naren Bag +1
We discuss an electro-osmotic flow near charged porous coatings of a finite hydrodynamic permeability, impregnated with an outer electrolyte solution. It is shown that their electr…
