SELF-CONSISTENT DISSIPATIVE PARTICLE DYNAMICS ALGORITHM

We propose an implementation of dissipative particle dynamics that is free of the inconsistencies that plagued earlier algorithms. The prese nt algorithm satisfies a form of microscopic reversibility. As a conse quence, we recover the correct equilibrium properties. Moreover, we ca n use much larger time steps than previously. We report a detailed com parison between simulated transport properties and the theoretical pre dictions. We find that the existing theory is only valid under very sp ecial conditions. A more general theory is still lacking.
