Effect of a Microscopic Roughness on Biological Adhesion of a Spherical Capsule
Aleksey V. Belyaev
By means of computer simulations, this work addresses adhesion of a deformable spherical capsule to a micro-rough surface consisting of a periodic array of pillars. Depending on th…
Long ligands reinforce biological adhesion under shear flow
Aleksey V. Belyaev
In this work the computer modeling has been used to show that longer ligands allow biological cells (e.g., blood platelets) to withstand stronger flows after their adhesion to soli…
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…
Threshold of microvascular occlusion: injury size defines the thrombosis scenario
Aleksey V. Belyaev, Mikhail A. Panteleev, Fazly I. Ataullakhanov
Damage to the blood vessel triggers formation of a hemostatic plug, which is meant to prevent bleeding, yet the same phenomenon may result in a total blockade of a blood vessel by…
Anisotropic flow in striped superhydrophobic channels
Jiajia Zhou, Aleksey V. Belyaev, Friederike Schmid +1
We report results of dissipative particle dynamics simulations and develop a semi-analytical theory of an anisotropic flow in a parallel-plate channel with two superhydrophobic str…
Tensorial slip of super-hydrophobic channels
Sebastian Schmieschek, Aleksey V. Belyaev, Jens Harting +1
We describe a generalization of the tensorial slip boundary condition, originally justified for a thick (compared to texture period) channel, to any channel thickness. The eigenval…
Drag force on a sphere moving towards an anisotropic super-hydrophobic plane
Evgeny S. Asmolov, Aleksey V. Belyaev, Olga I. Vinogradova
We analyze theoretically a high-speed drainage of liquid films squeezed between a hydrophilic sphere and a textured super-hydrophobic plane, that contains trapped gas bubbles. A su…
Electro-osmosis on anisotropic super-hydrophobic surfaces
Aleksey V. Belyaev, Olga I. Vinogradova
We give a general theoretical description of electro-osmotic flow at striped super-hydrophobic surfaces in a thin double layer limit, and derive a relation between the electro-osmo…
Wetting, roughness and hydrodynamic slip
Olga I. Vinogradova, Aleksey V. Belyaev
The hydrodynamic slippage at a solid-liquid interface is currently at the center of our understanding of fluid mechanics. For hundreds of years this science has relied upon no-slip…
Wetting, roughness and flow boundary conditions
Olga I. Vinogradova, Aleksey V. Belyaev
We discuss how the wettability and roughness of a solid impacts its hydrodynamic properties. We see in particular that hydrophobic slippage can be dramatically affected by the pres…
Hydrodynamic interaction with super-hydrophobic surfaces
Aleksey V. Belyaev, Olga I. Vinogradova
Patterned surfaces with large effective slip lengths, such as super-hydrophobic surfaces containing trapped gas bubbles, have the potential to reduce hydrodynamic drag. Based on lu…
Effective slip in pressure-driven flow past super-hydrophobic stripes
Aleksey V. Belyaev, Olga I. Vinogradova
Super-hydrophobic array of grooves containing trapped gas (stripes), have the potential to greatly reduce drag and enhance mixing phenomena in microfluidic devices. Recent work has…
