Lubrication of textured surfaces: a general theory for flow and shear stress factors

Phys Rev E Stat Nonlin Soft Matter Phys. 2012 Aug;86(2 Pt 2):026314. doi: 10.1103/PhysRevE.86.026314. Epub 2012 Aug 23.

Abstract

We report on a mean field theory of textured surface lubrication. We study the fluid flow dynamics occurring at the interface as a function of the texture characteristics, e.g. texture area density, shape and distribution of microstructures, and local slip lengths. The present results may be very important for the investigation of tailored microtextured surfaces for low-friction hydrodynamic applications.
