Abstract
The self-diffusion coefficient and the shear viscosity are calculated for a system evolving under dissipative particle dynamics in two and three dimensions. The self-diffusion coefficient agrees with that Marsh et al. although the shear viscosity has corrections absent in previous theories. These corrections arise from a subtle combination of convective and dissipative effects. When the present theory is compared with computer simulations of two dimensional fluids, it appears that the present work portrays albeit qualitatively the deviation of the dissipative and kinetic parts of the shear viscosity from the low friction limits depicted in the Marsh et al. work.
