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...

D Dissipative Particle Dynamics , Overview

Natural systems can be described at different scales based on both spatial and temporal size. In general, there are three different scales, i.e., micro-, meso-, and macroscales. A microscopic event occurs at nanometers in length and nanoseconds in time or, even less, governed by quantum mechanics or classical laws. Macroscale describes physical objects or phenomena that are measurable and visib...

Splitting for Dissipative Particle Dynamics

We study numerical methods for dissipative particle dynamics, a system of stochastic differential equations for simulating particles interacting pairwise according to a soft potential at constant temperature where the total momentum is conserved. We introduce splitting methods and examine the behavior of these methods experimentally. The performance of the methods, particularly temperature cont...
