Transport at the Fluid-Solid Interface

Transport in the presence of a fluid-solid interface is affected, and in many cases dominated, by the interaction between the fluid and solid in the interface vicinity. Transport in nanoscale devices and across 2D and 1D nanomaterials in particular, is synonymous with the presence of fluid-solid interfaces. Realizing the considerable potential of the multitude of applications curently being investigated in this context requires improved fundamental understanding of transport processes at the fluid-solid interface.<br/>In this talk we review recent progress in modeling certain canonical transport problems involving mass, momentum and energy transport, as well as the layering behavior of a fluid in the vicinity of a fluid-solid interface. We show that the fluid layering phenomenon can be described using scaling relations derived from the Nernst-Planck equation. Transport across the interface is studied using non-equilibrium statistical mechanics methods and is connected to the layering phenomena where appropriate. All results are validated using molecular dynamics simulations.
