Mesoscale hydrodynamics simulations of particle suspensions under shear flow: From hard to ultrasoft colloids

摘要: We discuss the nonequilibrium properties of rodlike and ultrasoft, star-polymer like colloidal particles in shear flow. Conformational, dynamical, as well rheological aspects are addressed for a broad range concentrations. For concentrated solutions colloids, we study phase separated system, where disordered coexists with nematic phase. starlike polymers consider systems various functionality, starting from linear polymers. The individual rods, polymers, or stars exhibit an intriguing dynamical behavior, which determines their macroscopic properties. Despite diversity on level, qualitatively similar e.g., thinning, yet some quantitative differences.
