Dissipative Particle Dynamics for Modeling Complex Fluidics
In this paper we present a new formulation of a Dissipative Particle Dynamics (DPD) model which is computationally less expensive than Voronoi-based DPD while preserving most of the advantages of Voronoi DPD over simple spherical-particle models. Aiming at fully three-dimensional flows an alternative to the straight-forward application of Voronoi DPD is desirable. The new model presented here can be derived from the Molecular Dynamics level by a coarse graining procedure (bottom-up approach) as well as from the continuum or macro-scale level conservation equations (top-down approach). In this paper the bottom-up derivation is presented.
