Theoretical modeling of catalytic self-propulsion
Tatiana V. Nizkaya, Evgeny S. Asmolov, Olga I. Vinogradova
Self-propelling particles or microswimmers have opened a new field of investigation with both fundamental and practical perspectives. They represent very convenient model objects f…
Self-diffusiophoresis of Janus particles that release ions
Evgeny S. Asmolov, Tatiana V. Nizkaya, Olga I. Vinogradova
Catalytic Janus swimmers demonstrate a diffusio-phoretic motion by self-generating the gradients of concentrations and electric potential. Recent work has focused on simplified cas…
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…
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…
Inertial migration of neutrally-buoyant particles in superhydrophobic channels
Tatiana V. Nizkaya, Evgeny S. Asmolov, Jens Harting +1
At finite Reynolds numbers particles migrate across flow streamlines to their equilibrium positions in microchannels. Such a migration is attributed to an inertial lift force, and…
