Abstract

A brief review is presented of the scaling of complex fluids, polymers and polyelectrolytes in solution and in confined geometry, in thermodynamical, structural and rheology properties using equilibrium and nonequilibrium dissipative particle dynamics simulations. All simulations were carried out on high performance computational facilities using parallelized algorithms, solved on computers using both central and graphical processing units. The scaling approach is shown to be a unifying axis around which general trends and basic knowledge can be gained, illustrated through a series of case studies.
