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’

Two dimensional numerical simulations of sets of vesicles in a Poiseuille flow are presented. Vesicles are a simple model to describe the dynamics of red cells in blood flow. At the scale of vesicles, the hydrodynamics is well described by the Stokes

Microfiltration of particles is modelled by the motion of particles embedded in a Stokes flow near a porous membrane in which Darcy equations apply. Stokes flow also applies on the other side of the membrane. A pressure gradient is applied across the

The method of fundamental solution is used to calculate the creeping flow around a spherical solid particle close to a porous membrane. The equations for the flow in the porous medium and conditions at the interface are satisfied automatically with t

The paper discusses the Green's function method of the Stokes flow equation in the presence of a slip wall. The far field of the Green's function is obtained and interpreted in terms of singularities. It is found that the flux for the stokeslet near

The creeping flow around several spherical particles moving on a line perpendicular to a plane wall is calculated numerically using the boundary integral method. The locations of the point forces on the surfaces of the spheres are chosen so as to des

The boundary integral equation method is extended to calculate the creeping flow around a solid body near a porous slab. The boundary condition on the slab is taken automatically into account by an appropriate Green's function calculated by Elasmi an

Navier's (1823) slip condition, where the tangential velocity is proportional to the shear stress, may apply at micro-scales for a viscous liquid on walls with modified surfaces, e.g. hydrophobic ones in water. Experiments by Lumma et al (2003) show

The Green function of the Stokes equations for the creeping flow of a viscous fluid near a porous slab is calculated analytically. The flow in the porous slab is represented by Darcy equations and the boundary condition on the interface between the f
