Abstract

Following recent experiments on thin films of simple molecular liquids confined between two solid plates, a simple model of the effective viscosity is proposed based on the assumption of wall-induced solid-like order in the liquid film. The ordering produces a dramatic increase of the viscosity as film thickness approaches molecular dimensions. Shear-induced melting of these solid-like boundary layers gives rise to non-Newtonian shear-rate dependence of the viscosity. The results are compared with the observations of Granick and co-workers, and further experiments are proposed.
