Title:

Transport in fluids and materials: Molecular dynamics beyond equilibrium

Abstract:

Viscous flow, heat conduction and thermal diffusion are important dynamical processes. They have an immediate bearing on the technical performance of fluids, materials, and interfaces, sometimes as a much-desired design goal, sometimes as an inevitable nuisance factor. Molecular dynamics has evolved to a state that transport processes can be quantitatively predicted and qualitatively understood at the molecular level. This talk will present molecular dynamics simulations aimed at thermal and flow transport properties in simple and complex fluids, polymers, and composites. It will cover peculiarities like non-Fourier behavior and thermal rectification in carbon nanotubes, the unexpectedly low thermal conductivity of polymer-carbon nanotube composites and the importance of the interfacial thermal conductance in evaporation processes. The non-equilibrium molecular dynamics techniques employed will be outlined.
