DPD Simulation of Nano-Polymer Chain behaviour in Electroosmotic Flow

In this paper, the simulation of polymer chain behaviour is studied for two modes: the inflation of fixed twoends polymer chain curvature and motion of polymer chain in electroosmotic flow (EOF) for various geometries. Weapply dissipative particle dynamics (DPD) method for simulation. Particles are driven by electroosmotic flow as externalbody force. Our aim from this paper is that amount of inflation of polymer chain in fixed two ends or amount of complexfreely motion of polymer in DPD solvent in nanochannel completely depend on particles interaction (fluid-fluid, fluidpolymer-polymer-polymer) in EOF which simulation for various condition is presented. Our results for simplenanochannel in EOF are validated with analytical results and we have developed our results when polymer chain subjectin simple and stenosis nanochannel for fixed two ends and also freely motion of polymer chain.
