A spring model for suspended particles in dissipative particle dynamics

A spring model for suspended particles in dissipative particle dynamics

This paper is concerned with the use of oscillating particles instead of the usual frozen particles to model a suspended particle in the dissipative particle dynamics (DPD) method. A suspended particle is represented by a set of basic DPD particles connected to reference sites by linear springs of very large stiffness. The reference sites, collectively modeling a rigid body, move as a rigid bod...

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...

A splitting scheme for highly dissipative Smoothed Dissipative Particle Dynamics

Smoothed Dissipative Particle Dynamics (SDPD) is a novel coarse-grained mesoscopic method for the simulation of complex fluids representing the effect of microscopic scales by a stochastic process. It has some advantages over more traditional particle-based methods but, on the other hand, shares some problems common to particle-based simulations of microfluidic systems. In particular a prohibit...
