Large Scale Simulation of Colloidal Suspensions
Michael Bybee, University of Illinois at Urbana-Champaign
The dynamics of concentrated suspensions of solid particles in a viscous fluid is a problem of great technical interest and computational challenge. Our goal is to develop fast algorithms for the computational study of these systems including the effects of many-body hydrodynamic interactions, interparticle forces, and stochastic Brownian motion.
Owing to the difficulty of accurately computing the hydrodynamic interactions, the computational cost of traditional methods scales as O(N³) which has limited simulations to systems of N=25-100 particles. In our research group, new algorithms have been developed which scale as
This poster outlines the governing equations and computational algorithms as well as presents some simulation results and plans for future research.
