Abstract

Colloidal dispersions, suspensions of small solid particles in a liquid, are an important member of soft matter. Their dynamics and rheological behavior are strongly influenced by hydrodynamic interactions between particles, but their analytical treatment is very difficult because of the long-range, many-body nature. Here we explain a principle of fluid particle dynamics method, which we deveopled to deal with interparticle hydrodynamic interactions properly. Taking gelation of colloidal particles and electrophoresis of charged colloids as examples, we consider dynamic many-body coupling between colloids and a liquid and its consequences.
