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…

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…

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…

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…
Flow-driven collapse of lubricant-infused surfaces
Evgeny S. Asmolov, Tatiana V. Nizkaya, Olga I. Vinogradova
Lubricant-infused surfaces in an outer liquid flow generally reduce viscous drag. However, owing to the meniscus deformation, the infused state could collapse. Here we discuss the…

Evgeny S. Asmolov, Tatiana V. Nizkaya, Olga I. Vinogradova
We ascertain the enhanced slip properties for a liquid flow over lubricant-infused unidirectional surfaces. This situation reflects many practical settings involving liquid flows p…
Boundary conditions at the gas sectors of superhydrophobic grooves

The hydrodynamics of liquid flowing past gas sectors of unidirectional superhydrophobic surfaces is revisited. Attention is focussed on the local slip boundary condition at the liq…
Inertial focusing of finite-size particles in microchannels
Evgeny S. Asmolov, Alexander L. Dubov, Tatiana V. Nizkaya +2
At finite Reynolds numbers, Re, particles migrate across laminar flow streamlines to their equilibrium positions in microchannels. This migration is attributed to a lift force, and…
Advective superdiffusion in superhydrophobic microchannels
Tatiana V. Nizkaya, Evgeny S. Asmolov, Olga I. Vinogradova
We consider pressure-driven flows in wide microchannels, and discuss how a transverse shear, generated by misaligned superhydrophobic walls, impacts cross-sectional spreading of Br…
Electro-hydrodynamics near Hydrophobic Surfaces
S. R. Maduar, A. V. Belyaev, V. Lobaskin +1
We show that an electro-osmotic flow near the slippery hydrophobic surface depends strongly on the mobility of surface charges, which are balanced by counter-ions of the electrosta…
Flows and mixing in channels with misaligned superhydrophobic walls
Tatiana V. Nizkaya, Evgeny S. Asmolov, Jiajia Zhou +2
Aligned superhydrophobic surfaces with the same texture orientation reduce drag in the channel and generate secondary flows transverse to the direction of the applied pressure grad…
