Abstract
A new mesoscopic simulation method, dissipative particle dynamics (DPD), is applied to model suspensions. DPD is a coarse-graining technology, in which several atoms are united into a single simulation particle so that simulation is realized in a larger length scale and time scale. Now this method has been widely used in simulating the rheology of colloidal suspensions, and mainly focused on the equilibrium dynamics and the steady-state shear rheological behaviors for a range of suspensions volume fractions. It is shown that the diffusion coefficient of dispersion decreased, but the viscosity of suspension increased at a given shear rate with the increase of volume fractions of suspension particles; the viscosity decreased with the increase of shear rate at the same volume fractions of suspensions.
