Abstract
We developed a simulation scheme called “Smoothed Profile (SP) method” to predict the dynamic behavior of colloidal dispersions. SP method provides a coupling scheme between continuum fluid dynamics and rigid-body dynamics through smoothed profile of colloidal particles. Moreover, SP method can incorporate multi-component fluids, such systems as charged colloids in electrolyte solutions. Numerical results which assess the hydrodynamic interactions of colloidal dispersions are presented to verify SP method. Application of SP method is not restricted to a Newtonian solvent, but any constitutive model can be handled. Henceforth, it is suitable to treat colloidal dispersions in complex fluids where solvent-mediated interaction dominates the dynamical behaviors of colloids.
