# Microfluidics: The no-slip boundary condition

@article{Lauga2005MicrofluidicsTN, title={Microfluidics: The no-slip boundary condition}, author={Eric Lauga and Michael P. Brenner and Howard A. Stone}, journal={arXiv: Soft Condensed Matter}, year={2005}, pages={1219-1240} }

The no-slip boundary condition at a solid-liquid interface is at the center of our understanding of fluid mechanics. However, this condition is an assumption that cannot be derived from first principles and could, in theory, be violated. In this chapter, we present a review of recent experimental, numerical and theoretical investigations on the subject. The physical picture that emerges is that of a complex behavior at a liquid/solid interface, involving an interplay of many physico-chemical…

It is found that the apparent slip is independent of the detailed boundary shape, but only given by the distribution of surface heights, and it is shown that slip diverges as the amplitude of the roughness increases which highlights the importance of a proper treatment of surface variations in very confined geometries.

The amount of slip is found to be independent of the channel size, but is a function of the shear rate, the type of liquid (polar or nonpolar molecular structure), and the morphology of the solid surface (molecular-level smoothness).
