| Abstract: We present a general algorithm for calculating the spatial variation of the shear viscosity and thermal conductivity through an equilibrium solid-liquid interface using the zero-flux version of the boundary fluctuation theory. In the case of an equilibrium interface between a high melting point Lennard-Jones solid and a low melting point Lennard-Jones liquid, we find that the transport coefficients deviate from the bulk values only in a narrow layer close to the interface. We observe a sliding friction of the liquid against the surface of the solid that increases with increased wetting of the solid by the liquid. The thermal conductivity, in contrast, is suppressed in the interfacial region, irrespective of how the liquid wets the solid. |

| Title: A continuum model for the flow of thin liquid films over intermittently chemically patterned surfaces |
| Authors: |
| Author Full Names: Sprittles, J. E.; Shikhmurzaev, Y. D. |

| Abstract: It is known from both experiments and molecular dynamics simulations that chemically patterning a solid surface has an effect on the flow of an adjacent liquid. This fact is in stark contrast with predictions of classical fluid mechanics where the no-slip boundary condition is insensitive to the chemistry of the solid substrate. It has been shown that the influence on the flow caused by a steep change in the wettability of the solid substrate can be described in the framework of continuum mechanics using the interface formation theory. The present work extends this study to the case of intermittent patterning. Results show that variations in wettability of the substrate can significantly affect the flow, especially of thin films, which may have applications to the design of microfluidic devices. |
