Simulation of high Schmidt number fluids with dissipative particle dynamics: Parameter identification and robust viscosity evaluation

Dissipative Particle Dynamics simulation hydrated Nafion EW 1200 as fuel cell membrane in nanoscopic scale

The microphase separation of hydrated perfluorinated sulfonic acid membrane Nafion was investigated using Dissipative Particle Dynamics (DPD). The nafion as a polymer was modelled by connecting coarse grained beads which corresponds to the hydrophobic backbone of polytetrafluoroethylene and perfluorinated side chains terminated by hydrophilic end particles of sulfonic acid groups [1, 2]. Each f...

Dissipative Particle Dynamics Modelling of Low Reynolds Number Incompressible Flows

Simulation of Droplet Breakup by Dissipative Particle Dynamics (DPD)

Coil-to-globule transition by dissipative particle dynamics simulation.

The dynamics of a collapsing polymer under a temperature quench in dilute solution is investigated by dissipative particles dynamics. Hydrodynamic interactions and many-body interaction are preserved naturally by incorporating explicit solvent particles in this approach. Our simulation suggests a four-stage collapse pathway: localized clusters formation, cluster coarsening in situ, coarsening i...

Polyelectrolyte electrophoresis in nanochannels: a dissipative particle dynamics simulation.

We present mesoscopic dissipative particle dynamics-simulations of polyelectrolyte electrophoresis in confined nanogeometries for varying salt concentration and surface slip conditions. Special attention is given to the influence of electroosmotic flow on the migration of the polyelectrolyte. The effective polyelectrolyte mobility is found to depend strongly on the boundary properties, that is,...
