Molecular Simulations of Knudsen Wall-slip: Effect of Wall Morphology

This work involves a molecular simulation study of the phenomena of wall slip occurring in rarefied gases flowing through microand nano-channels. A simulation strategy that mimics a scattering experiment is developed in order to compute the tangential momentum accommodation coefficient ( f) which governs the degree of slip at the wall surface. Noninteracting gas molecules are bombarded at an at...

Quantifying hydrodynamic slip: a comprehensive analysis of dewetting profiles.

To characterize nontrivial boundary conditions of a liquid flowing past a solid, the slip length is commonly used as a measure. From the profile of a retracting liquid front (e.g., measured with atomic force microscopy), the slip length can be extracted with the help of a Stokes model for a thin liquid film dewetting from a solid substrate. Specifically, we use a lubrication model derived from ...
