Slip boundaries in nanopores

Molecular Simulation, 2011
The flow of liquid water confined within slit pores formed from amorphous surfaces of carbon and polydimethylsiloxane (PDMS) has been investigated using molecular dynamics techniques. For PDMS (including plasma treated forms) the slip length is found to be very small, and there are essentially stick boundary conditions.

Limits of the Hydrodynamic No-Slip Boundary Condition

Physical Review Letters, 2002
A controversial point in fluid dynamics is to distinguish the relative importance of surface roughness and fluid-surface intermolecular interactions in determining the boundary condition. Here hydrodynamic forces were compared for flow of Newtonian fluids past surfaces of variable roughness but similar, poorly wetted, surface chemistry.

Boundary slip from the immersed boundary lattice Boltzmann models

Physical Review E, 2009
We report an interesting and important observation of the velocity fields from immersed boundary lattice Boltzmann methods (IB-LBM). The computed velocity profiles can deviate from theoretical predictions greatly even for very simple flow situations, both in the immersed boundary layer and the bulk region.

THE NO-SLIP BOUNDARY CONDITION IN FINITE DIFFERENCE APPROXIMATIONS

International Journal for Numerical Methods in Fluids, 1996
Summary: A finite difference method for the Navier-Stokes equations in vorticity-streamfunction formulation is proposed to resolve the difficulty of the lack of a vorticity boundary condition at a no-slip boundary. It is particularly suitable for flows in regions with complicated geometries.

No-Slip Hydrodynamic Boundary Condition for Hydrophilic Particles

Physical Review Letters, 2007
We describe measurement and interpretation of the force acting on a smooth hydrophilic glass particle during rapid (1-100 microm s(-1) approach to, and separation from, a hydrophilic glass plate in viscous concentrated aqueous sucrose solutions (0.001 Pa ...

On the no-slip boundary condition

Journal of Fluid Mechanics, 1973
It has been argued that the no-slip boundary condition, applicable when a viscous fluid flows over a solid surface, may be an inevitable consequence of the fact that all such surfaces are, in practice, rough on a microscopic scale: the energy lost through viscous dissipation as a fluid passes over and around these irregularities is sufficient to ensure
