Self-diffusion coefficient in smoothed dissipative particle dynamics

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...

Fluid particle dynamics: A synthesis of dissipative particle dynamics and smoothed particle dynamics

– We present a generalization of dissipative particle dynamics that includes shear forces between particles. The new algorithm has the same structure as the (isothermal) smoothed particle dynamics algorithm, except that it conserves angular momentum and includes thermal fluctuations consistently with the principles of equilibrium statistical mechanics. This clarifies the connection of dissipati...

Smoothed dissipative particle dynamics - a mesoscopic particle-based hydrodynamic technique for complex fluids

Smoothed dissipative particle dynamics (SDPD) combines two popular mesoscopic techniques, the smoothed particle hydrodynamics and dissipative particle dynamics (DPD) methods, and can be considered as an improved DPD approach. Advantages of the SDPD method over conventional DPD include the possibility of using an arbitrary equation of state, direct input of transport properties, and a well-defin...
