Flow at Interfaces: Boundary Conditions and Multiscale Approaches

Dr. Mark Robbins

Department of Physics & Astronomy at Johns Hopkins University

Abstract:   Traditional approaches to dynamics at interfaces use continuum mechanics and phenomenological boundary conditions. The first part of the talk will briefly describe qualitative failures of common boundary conditions and use molecular dynamics to derive appropriate ones. The next part of the talk will describe two multiscale approaches. One uses detailed atomistic simulations to construct a realistic mesoscale fluid model. The parameters of this model are very different from those commonly assumed based on symmetry arguments. The second multiscale approach is a simultaneous atomistic and continuum simulation that has been used to study flow near solid surfaces.
