| Abstract: | The problem of characterizing a fluid flow near a solid surface is considered. The interface parameters are the friction coefficient and the hydrodynamic location of the interface. A method to obtain quantitatively these parameters from a non equilibrium molecular dynamics (NEMD) simulation is presented. Results for the flow of a soft sphere fluid confined between two corrugated surfaces are presented. |
