Modelling of contact regimes in wire sawing with dissipative particle dynamics.

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...

Collective effects in dissipative particle dynamics

We study the detailed dynamics of DPD particles by looking at the velocity autocorrelation function. We observe that in the regimes of interest for simulations, the velocity autocorrelation function reflects the hydrodynamic behavior of these particles.  1999 Elsevier Science B.V.

Modelling of Cylindrical Contact Theories ‎of Hertz and JKR for the Manipulation of ‎Biological Micro/Nanoparticles

   This paper deals with the development and modeling of cylindrical contact theories and also the simulation of contact forces to be applied in the manipulation of various biological micro/nanoparticles by means of the AFM. First, the simulation of contact forces in four environments has been carried out, which are the most commonly used fluid in biomanipulation. Then, the spherical and cy...

Dissipative Particle Dynamics Modelling of Low Reynolds Number Incompressible Flows

بررسی دینامیکی ذرات خارج شده از هسته برانگیخته با استفاده از روش لانژوین

Using Langevin dynamics and the dissipative nature of the fission process, we have studied dynamical variations of nucleus from the formation of the compound nucleus to separation stage of two fission fragments. During this dissipative process, particles such as neutron, proton, alpha particle and gamma ray emit from the compound system. In the present work, the number of emitted particles usin...
