Dissipative particle dynamics (DPD) is an effective mesoscopic particle modelwith a lower computational cost than molecular dynamics because of the softpotentials that it employs. However, the soft potential is not strong enough toprevent the DPD particles that are used to represent the fluid from penetratingsolid boundaries represented by stationary DPD particles. A phase fieldvariable, , is used to indicate the phase at point and time t, with a smoothtransition from -1 (phase 1) to +1 (phase 2) across the interface. We describean efficient implementation of no-slip boundary conditions in DPD models thatcombines solid-liquid particle-particle interactions with reflection at a sharpboundary located with subgrid scale accuracy using the phase field. Thisapproach can be used for arbitrarily complex flow geometries and other similarparticle models (such as smoothed particle hydrodynamics), and the validity ofthe model is demonstrated by DPD simulations of flow in confined systems withvarious geometries.
