This paper derives the effective force between particles in the framework of dissipative particle dynamics (DPD) by using the formalism discussed by Revenga et al. [Int. J. Mod. Phys. C 9 (1998) 1319]. In order to mimic realistic systems, we obtained explicit expressions for the effective...

The efficient simulation of models defined in terms of stochastic differential equations (SDEs) depends critically on an efficient integration scheme. In this article, we investigate under which conditions the integration schemes for general SDEs can be derived using the Trotter expansion. It...

The hydrodynamics of viscoelastic materials (for example, polymer melts and solutions) presents interesting and complex phenomena, for example, instabilities and turbulent flow at very low Reynolds numbers due to normal stress effects and the existence of a finite stress relaxation time. This...

Solutions of flexible polymer chains with harmonic bonds undergoing rectilinear flow in slit pores are investigated via dissipative particle dynamics (DPD) simulations. We found that when DPD with low Schmidt number (Sc∼1) is used, the polymer chains tend to migrate across the streamlines...
