Simulation method of colloidal suspensions with hydrodynamic interactions: fluid particle dynamics

Phys Rev Lett. 2000 Aug 7;85(6):1338-41. doi: 10.1103/PhysRevLett.85.1338.

Abstract

We develop a new simulation method of colloidal suspensions, which we call a "fluid particle dynamics" (FPD) method. This FPD method, which treats a colloid as a fluid particle, removes the difficulties stemming from a solid-fluid boundary condition in the treatment of hydrodynamic interactions between the particles. The importance of interparticle hydrodynamic interactions in the aggregation process of colloidal particles is demonstrated as an example. This method can be applied to a wide range of problems in colloidal science.
