Abstract:

We develop new non-periodic boundary conditions in molecular dynamics (MD) simulations, applied to inlets and outlets of nanochannel flow problems. We demonstrate Poiseuille-type flow simulations for two applications in relatively complex geometries: a mixing channel case of three inlet one outlet design; and an extensional flow problem showing droplet deformation in the throat of the channel.
