Lubricating motion of a sphere towards a thin porous slab with Saffman slip condition
Autor: Antoine Sellier, Sondes Khabthani, François Feuillebois
Publikováno v: Journal of Fluid Mechanics. 867:949-968
Near-contact hydrodynamic interactions between a solid sphere and a plane porous slab are investigated in the framework of lubrication theory. The size of pores in the slab is small compared with the slab thickness so that the Darcy law holds there.

Effective viscosity of a dilute homogeneous suspension of spheres in Poiseuille flow between parallel slip walls
Autor: Néjiba Ghalya, Maria L. Ekiel-Jeżewska, François Feuillebois, Antoine Sellier
Publikováno v: Journal of Fluid Mechanics. 899
For flows in microchannels, a slip on the walls may be efficient in reducing viscous dissipation. A related issue, addressed in this article, is to decrease the effective viscosity of a dilute monodisperse suspension of spheres in Poiseuille flow by

High-frequency effective viscosity of a dilute suspension of particles in Poiseuille flow between parallel walls

Publikováno v: Journal of Fluid Mechanics. 800:111-139
It is shown that the formal expression for the effective viscosity of a dilute suspension of arbitrary-shaped particles in Poiseuille flow contains a novel quadrupole term, besides the expected stresslet. This term becomes important for a very confin

International audience; In boundary element method (BEM), one encounters linear system with a dense and non-symmetric square matrix which might be so large that inverting the linear system is too prohibitive in terms of cpu time and/or memory. Each u

This work considers a nearly spherical bubble and a nearly flat free surface interacting under buoyancy at vanishing Bond number Bo. For each perturbed surface, the deviation from the unperturbed shape is asymptotically obtained at leading order on B

Motion of a solid particle in a shear flow along a porous slab

Journal of Fluid Mechanics, Cambridge University Press (CUP), 2012, 713, pp.271-306. ⟨10.1017/jfm.2012.457⟩
The flow field around a solid particle moving in a shear flow along a porous slab is obtained by solving the coupled Stokes–Darcy problem with the Beavers and Joseph slip boundary condition on the slab interfaces. The solution involves the Green’

This work examines the slow viscous migration of two insulting spherical bubbles freely suspended in a conducting Newtonian liquid when subject to superposed uniform and steady electric and magnetic fields. Assuming vanishing Reynolds and Hartmann nu

A general expression for the effective viscosity of a dilute suspension of arbitrary-shaped particles in linear shear flow between two parallel walls is derived in terms of the induced stresslets on particles. This formula is applied to $N$-bead rods

The axisymmetric gravity-driven dynamics of a bubble rising toward a free surface is addressed for gas-liquid interfaces having unequal surface tensions. The liquid flow is governed by the Stokes equations which are here solved using a boundary eleme
